We risk damaging the artifacts and removing the fine surface detailing if we try mechanical cleaning methods.”</p> <p>The coin imaging and analysis project began as an assignment for the Analytical Electron Microscopy course Stanko took with <strong>Janet Howe</strong>, an associate professor in the department of materials science and engineering and the department of chemical engineering and applied chemistry and Stanko’s PhD co-supervisor.</p> <p>Stanko and collaborators, including Howe, PhD candidate <strong>Dian (Jack) Yu</strong> and post-doctoral fellow&nbsp;<strong>Michel Haché</strong>, developed a strategy to examine the coins with a scanning electron microscope paired with energy-dispersive X-ray spectroscopy (SEM-EDS).</p> <p>“Once we know more about the chemical composition on the surfaces of these coins, we can advise ROM conservators on non-destructive treatment strategies and storage solutions,” Stanko says.</p> <p>The project has proven to be challenging. Since EDS works by exciting the electrons on the surface of a sample to emit X-ray signatures, the team needed to fix the position of the coins – without the use of clamps or guides that might cause damage – for the signals to hit the detector in just the right way.</p> <figure role="group" class="caption caption-drupal-media align-center"> <div> <div class="field field--name-field-media-image field--type-image field--label-hidden field__item"> <img loading="lazy" src="/sites/default/files/styles/scale_image_750_width_/public/2024-01/Collage_ROMkomma-OCCAM-coins---Jan2024-crop.jpg?itok=IszKhNM9" width="750" height="559" alt="&quot;&quot;" class="image-style-scale-image-750-width-"> </div> </div> <figcaption><em>One of the ancient Greek coins being analyzed at OCCAM is seen on the top left (photo: Laura Lipcsei, Royal Ontario Museum).

It’s not just about having access to state-of-the-art technology and tools, this is an excellent team to work with,” says Lipcsei. “They are sharing important information, and we couldn’t do our work without them.”</p> <p>The ROMkomma project is just one of many currently underway at the centre right now.</p> <p>“OCCAM is the infrastructure supporting research across U of T and beyond,” says Howe, the newly appointed co-director of OCCAM, who played a leading role in installing the equipment at the centre.</p> <p>“Many branches of science and engineering rely on understanding the structure of materials at atomic and nano scales, whether it’s related to designing catalysts for green energy, developing new biomolecules in medicine or enhancing microchips in our smartphones. Our work benefits every researcher tackling today’s grand challenges.”</p> <p>Howe is looking forward to an upcoming collaboration with Hitachi High-Tech, involving a low-cost structural analysis tool that could significantly bring down the cost of characterizing the structure of new materials.</p> <p>She identifies the centre’s focus on teaching as one of its core strengths.</p> <p>“At OCCAM, we don’t restrict access to our world-class instrumentation to post-doctoral fellows and senior researchers. Undergraduate and graduate student get hands-on experience and are encouraged to come to us with projects.”</p> </div> <div class="field field--name-field-news-home-page-banner field--type-boolean field--label-above"> <div class="field__label">News home page banner</div> <div class="field__item">Off</div> </div> Wed, 10 Jan 2024 17:05:32 +0000 Christopher.Sorensen 305213 at U of T researchers help study, catalogue ROM's ancient Greek coins /news/u-t-researchers-help-study-catalogue-rom-s-ancient-greek-coins <span class="field field--name-title field--type-string field--label-hidden">U of T researchers help study, catalogue ROM's ancient Greek coins</span> <div class="field field--name-field-featured-picture field--type-image field--label-hidden field__item"> <img loading="eager" srcset="/sites/default/files/styles/news_banner_370/public/2023-10/lede-crop.jpg?h=afdc3185&amp;itok=PZQCH-Yy 370w, /sites/default/files/styles/news_banner_740/public/2023-10/lede-crop.jpg?h=afdc3185&amp;itok=UD-Rrhkj 740w, /sites/default/files/styles/news_banner_1110/public/2023-10/lede-crop.jpg?h=afdc3185&amp;itok=UXPCBORj 1110w" sizes="(min-width:1200px) 1110px, (max-width: 1199px) 80vw, (max-width: 767px) 90vw, (max-width: 575px) 95vw" width="740" height="494" src="/sites/default/files/styles/news_banner_370/public/2023-10/lede-crop.jpg?h=afdc3185&amp;itok=PZQCH-Yy" alt="&quot;&quot;"> </div> <span class="field field--name-uid field--type-entity-reference field--label-hidden"><span>Christopher.Sorensen</span></span> <span class="field field--name-created field--type-created field--label-hidden"><time datetime="2023-10-19T13:14:14-04:00" title="Thursday, October 19, 2023 - 13:14" class="datetime">Thu, 10/19/2023 - 13:14</time> </span> <div class="clearfix text-formatted field field--name-field-cutline-long field--type-text-long field--label-above"> <div class="field__label">Cutline</div> <div class="field__item"><p><em>An Athenian coin, circa 454-404 BCE, with the head of Athena and an owl near an olive branch (photos by Laura Lipcsei © Royal Ontario Museum)&nbsp;</em></p> </div> </div> <div class="field field--name-field-author-reporters field--type-entity-reference field--label-hidden field__items"> <div class="field__item"><a href="/news/authors-reporters/sean-mcneely" hreflang="en">Sean McNeely</a></div> </div> <div class="field field--name-field-topic field--type-entity-reference field--label-above"> <div class="field__label">Topic</div> <div class="field__item"><a href="/news/topics/our-community" hreflang="en">Our Community</a></div> </div> <div class="field field--name-field-story-tags field--type-entity-reference field--label-hidden field__items"> <div class="field__item"><a href="/news/tags/classics" hreflang="en">Classics</a></div> <div class="field__item"><a href="/news/tags/faculty-arts-science" hreflang="en">Faculty of Arts &amp;

First, a blank coin was heated to become softer and placed on a die containing the design on the one side – the obverse or “heads” side. Then another die containing the design of the other side – the reverse or “tails” side – was placed on top and was struck by a hammer, creating a two-sided coin in a single blow.</p> <figure role="group" class="caption caption-drupal-media align-center"> <div> <div class="field field--name-field-media-image field--type-image field--label-hidden field__item"> <img loading="lazy" src="/sites/default/files/styles/scale_image_750_width_/public/2023-10/soldier-owl-vase-slide.jpg?itok=QdJjwETX" width="750" height="500" alt="&quot;&quot;" class="image-style-scale-image-750-width-"> </div> </div> <figcaption><em>A Greek coin (circa 125-124 BCE) with the head of Athena and an owl standing on an amphora – a type of Greek vase.</em></figcaption> </figure> <p>One group of coins the team is studying is from ancient Athens, one of the earliest Greek cities to create its own coinage in the middle of the sixth century BCE.</p> <p>“If you look at the Athenian coins, what's striking is that they’re instantly recognizable as coins, monetary instruments like ours – and partly because, in many ways, they resemble the coins we have in our pocket,” Akrigg says.</p> <p>On the “heads” side, many of these coins have a profile image of Athena – the goddess of wisdom and war, and the city’s protector. The other side of the coins display symbols associated with Athena such as an owl or an olive branch.</p> <p>“The owl is a symbol of wisdom associated with the goddess, though owls have other meanings as well,” says Akrigg.</p> <figure role="group" class="caption caption-drupal-media align-center"> <div> <div class="field field--name-field-media-image field--type-image field--label-hidden field__item"> <img loading="lazy" src="/sites/default/files/styles/scale_image_750_width_/public/2023-10/profile-man-bird-slide.jpg?itok=ZwYbPhEW" width="750" height="500" alt="&quot;&quot;" class="image-style-scale-image-750-width-"> </div> </div> <figcaption><em>A coin from the Hellenistic period (circa 300-295 BCE) with the head of a young Herakles and Zeus sitting on a throne holding an eagle.</em></figcaption> </figure> <p>Later coins from the Seleukid Empire often placed rulers on the face of the coin – especially Alexander the Great, with the image of a god such as Zeus or Apollo on the reverse, as well as a variety of creatures such as turtles, lions, elephants.</p> <p>“At the end of the fourth century BCE, some of Alexander’s successor kings put Alexander's portrait on their coins, but then after a while, the kings thought, ‘Hang on, why don't we just put ourselves on?’” says Akrigg. “And so coins became a way to assert their own legitimacy as kings in their new kingdoms.”</p> <p>For Zabalueva, the ROMkomma project is more than the analysis of ancient artifacts and identifying whose face is on what coin&nbsp;– it’s a journey into cultural history.</p> <p>“Each kingdom depicted on their coins represents something very important for the community: it might be a god or goddess, an animal, a ruler, an abstract symbol,” she says.</p> <p>“It's much more than just a means of exchange. It's a display of local culture, history, power and state propaganda all at the same time.”</p> <p>That tradition remains relatively unchanged. Most Canadian coins have a portrait of the late Queen Elizabeth II on one side&nbsp;– and for our loonies, quarters and nickels, a loon, a caribou and a beaver, respectively, on the opposite side.</p> <p>Though ROMkomma is a massive project that will ultimately take years to complete, Akrigg says he will always get a charge out of seeing the coins first-hand.</p> <p>“The coins are mass produced but because they're handmade, each one is unique,” he says. “No two coins are exactly alike. They’re unique little works of art.”</p> <p>&nbsp;</p> </div> <div class="field field--name-field-news-home-page-banner field--type-boolean field--label-above"> <div class="field__label">News home page banner</div> <div class="field__item">Off</div> </div> Thu, 19 Oct 2023 17:14:14 +0000 Christopher.Sorensen 303639 at Archaeologist looks to ancient solutions to help solve contemporary global problems /news/researcher-turns-ancient-solutions-help-solve-contemporary-global-problems <span class="field field--name-title field--type-string field--label-hidden">Archaeologist looks to ancient solutions to help solve contemporary global problems</span> <div class="field field--name-field-featured-picture field--type-image field--label-hidden field__item"> <img loading="eager" srcset="/sites/default/files/styles/news_banner_370/public/2023-08/jennings-book.jpg?h=afdc3185&amp;itok=kifRWwk0 370w, /sites/default/files/styles/news_banner_740/public/2023-08/jennings-book.jpg?h=afdc3185&amp;itok=vHKZkF98 740w, /sites/default/files/styles/news_banner_1110/public/2023-08/jennings-book.jpg?h=afdc3185&amp;itok=0q0oQtFm 1110w" sizes="(min-width:1200px) 1110px, (max-width: 1199px) 80vw, (max-width: 767px) 90vw, (max-width: 575px) 95vw" width="740" height="494" src="/sites/default/files/styles/news_banner_370/public/2023-08/jennings-book.jpg?h=afdc3185&amp;itok=kifRWwk0" alt="&quot;&quot;"> </div> <span class="field field--name-uid field--type-entity-reference field--label-hidden"><span>Christopher.Sorensen</span></span> <span class="field field--name-created field--type-created field--label-hidden"><time datetime="2023-08-22T16:04:06-04:00" title="Tuesday, August 22, 2023 - 16:04" class="datetime">Tue, 08/22/2023 - 16:04</time> </span> <div class="clearfix text-formatted field field--name-field-cutline-long field--type-text-long field--label-above"> <div class="field__label">Cutline</div> <div class="field__item"><p><em>Justin Jennings, the&nbsp;curator of world cultures at the&nbsp;Royal Ontario Museum and an associate professor in U of T’s&nbsp;

Authoritarianism and nationalism are once again on the rise and trading blocs based on Western ideals did not anticipate the rise of economies in the East&nbsp;– all of which can make international co-operation more difficult.</p> <p>Yet, Jennings says before the rise of the nation-state&nbsp;people often governed themselves in a more flexible, borderless way.</p> <p>He says one such society is the Haudenosaunee Confederacy, a group of First Nations Peoples in the northeastern region of North America. The Confederacy’s constitution, known as the Great Law of Peace, outlined a detailed, thoughtful process to be used when seeking consensus on important decisions.</p> <p>In fact, when crafting their own constitution, the founding fathers of the United States were initially curious about incorporating ideas from the Great Law of Peace,&nbsp;Jennings says.</p> <p>“I quote from John Adams in the book, who said the framers of the constitution could learn a lot from the Haudenosaunee,” he says.</p> <p>“[But] then they didn’t – because those ideas weren’t in their wheelhouse.”</p> <p>While Jennings notes that some ancient societies were also hierarchical – ancient Egypt, he says, was a “pyramid society in more ways than one”&nbsp;–&nbsp;he asks whether a more decentralized governance model, where power is more equitably shared, might not be more responsive to our changing times.</p> <p>“The galactic polities of traditional Southeast Asian kingdoms were often organized around a centre, with different groups in and out of the orbit of that centre. There wasn’t a lot of effort towards creating rigid connections between that centre and other places. Now, is this a good idea? I’m not sure. But it’s a different idea and one that should be explored because putting patches on the big bucket that is the nation-state isn’t proving very effective.”</p> <figure role="group" class="caption caption-drupal-media align-center"> <div> <div class="field field--name-field-media-image field--type-image field--label-hidden field__item"> <img loading="lazy" src="/sites/default/files/styles/scale_image_750_width_/public/2023-08/GettyImages-604435103%20%281%29.jpg?itok=mEFMWqVs" width="750" height="504" alt="&quot;&quot;" class="image-style-scale-image-750-width-"> </div> </div> <figcaption>A&nbsp;<em>council meeting held by </em>the&nbsp;<em>Onondaga, one of the nations of the Haudenosonee&nbsp;Confederacy, is depicted from the 1700s (Illustration by H.

He shows how the Enga people of Papua New Guinea defused warfare and resolved economic inequality through a system known as the “tee cycle,” and how societies such as the Pomo of northern California organized daily life by creating order out of anarchy.</p> <p>Hippies experimented with anarchy in the 1960s, he adds, “but communes often failed because members weren’t looking at solid examples of communal, collective, egalitarian structures that lasted millennia.”&nbsp;</p> <p>While Jennings is studying smaller societies, he believes there are nevertheless learnings that could inform global governance.</p> <p>“Certainly there are scalar elements,” he says. “As a community gets larger it does tend to get more hierarchical, and the decision-making process changes. But this book suggests there may be alternative pathways. Those New Guinea tee cycles, for example, created vast amounts of wealth moving from one side of the country to the other. Thanks to a solid overarching structure, they had a playing field that was much larger than the village where they lived their day-to-day lives. This allowed them to interact with and organize hundreds of thousands of people doing things hundreds of kilometers away.”</p> <p>As the world changes and our concerns mount, Jennings says rather than rely on ideas that clearly aren’t working, we should look to the past to find new solutions.</p> <p>“Human history is all about trying to solve problems together,” he says. “We’ve been doing it successfully for many years. Now, as we take on some of the biggest challenges that humans have ever faced, it would be wrong for us not to be looking at other ways that people can come together to solve issues, especially because the context in which some groups used to&nbsp;– and in some cases still continue to&nbsp;– live is in many ways parallel to where our societies are going in this increasingly globalized world.”</p> </div> <div class="field field--name-field-news-home-page-banner field--type-boolean field--label-above"> <div class="field__label">News home page banner</div> <div class="field__item">Off</div> </div> Tue, 22 Aug 2023 20:04:06 +0000 Christopher.Sorensen 302703 at Researchers discover the oldest species of swimming jellyfish: CNN /news/researchers-discover-oldest-species-swimming-jellyfish-cnn <span class="field field--name-title field--type-string field--label-hidden">Researchers discover the oldest species of swimming jellyfish: CNN</span> <div class="field field--name-field-featured-picture field--type-image field--label-hidden field__item"> <img loading="eager" srcset="/sites/default/files/styles/news_banner_370/public/2023-08/fa643856-0b9b-4407-8542-54b9c4823bf9.jpg?h=58e332cb&amp;itok=X7JUhbXN 370w, /sites/default/files/styles/news_banner_740/public/2023-08/fa643856-0b9b-4407-8542-54b9c4823bf9.jpg?h=58e332cb&amp;itok=xyER1dtg 740w, /sites/default/files/styles/news_banner_1110/public/2023-08/fa643856-0b9b-4407-8542-54b9c4823bf9.jpg?h=58e332cb&amp;itok=DoiHWHoq 1110w" sizes="(min-width:1200px) 1110px, (max-width: 1199px) 80vw, (max-width: 767px) 90vw, (max-width: 575px) 95vw" width="740" height="494" src="/sites/default/files/styles/news_banner_370/public/2023-08/fa643856-0b9b-4407-8542-54b9c4823bf9.jpg?h=58e332cb&amp;itok=X7JUhbXN" alt="&quot;&quot;"> </div> <span class="field field--name-uid field--type-entity-reference field--label-hidden"><span>Christopher.Sorensen</span></span> <span class="field field--name-created field--type-created field--label-hidden"><time datetime="2023-08-08T15:20:32-04:00" title="Tuesday, August 8, 2023 - 15:20" class="datetime">Tue, 08/08/2023 - 15:20</time> </span> <div class="clearfix text-formatted field field--name-field-cutline-long field--type-text-long field--label-above"> <div class="field__label">Cutline</div> <div class="field__item"><p><em>An artist’s depiction of Burgessomedusa phasmiformis swimming 505 million years ago in the Cambrian sea, where it was believed to be one of the largest predators (illustration by Christian McCall)</em></p> </div> </div> <div class="field field--name-field-topic field--type-entity-reference field--label-above"> <div class="field__label">Topic</div> <div class="field__item"><a href="/news/topics/breaking-research" hreflang="en">Breaking Research</a></div> </div> <div class="field field--name-field-story-tags field--type-entity-reference field--label-hidden field__items"> <div class="field__item"><a href="/news/tags/ecology-and-evolutionary-biology" hreflang="en">Ecology and Evolutionary Biology</a></div> <div class="field__item"><a href="/news/tags/faculty-arts-science" hreflang="en">Faculty of Arts &amp; Science</a></div> <div class="field__item"><a href="/news/tags/research-innovation" hreflang="en">Research &amp; Innovation</a></div> <div class="field__item"><a href="/news/tags/royal-ontario-museum" hreflang="en">Royal Ontario Museum</a></div> </div> <div class="clearfix text-formatted field field--name-body field--type-text-with-summary field--label-hidden field__item"><p>Researchers at the Royal Ontario Museum (ROM) and the Ƶ have discovered evidence of the oldest swimming jellyfish in the fossil record, <a href="https://www.cnn.com/2023/08/02/world/oldest-swimming-jellyfish-fossils-scn/index.html">CNN reports</a>.</p> <p>A study, <a href="https://royalsocietypublishing.org/doi/10.1098/rspb.2022.2490">published in <em>Proceedings of the Royal Society B</em></a>, documented the finding of 182 fossils in the Burgess Shale, a deposit in B.C.’s Rocky Mountains&nbsp;known for its rich preservation of the explosion of life during the Cambrian period.</p> <p>Researchers found that the fossils belong to a newly identified species of jellyfish that swam in the Earth’s oceans 505 million years ago, CNN reported.

The most iconic representative of this group is the streamlined predator&nbsp;Anomalocaris, which may itself have approached a metre in length. Like all radiodonts,&nbsp;Titanokorys&nbsp;had multifaceted eyes, a pineapple slice-shaped, tooth-lined mouth, a pair of spiny claws below its head to capture prey and a body with a series of flaps for swimming. Within this group, some species also possessed large, conspicuous head carapaces, with&nbsp;Titanokorys&nbsp;being one of the largest ever known.</p> <p>“Titanokorys&nbsp;is part of a subgroup of radiodonts, called hurdiids, characterized by an incredibly long head covered by a three-part carapace that took on myriad shapes. The head is so long relative to the body that these animals are really little more than swimming heads,” added <strong>Joe Moysiuk</strong>, co-author of the study, and a PhD student in EEB based at the ROM.</p> <div> <div class="image-with-caption right"><em><img class="migrated-asset" src="/sites/default/files/Andrew%20Gregg%20_Joe%20and%20JB_8793%5B1688%5D-crop.jpg" alt><span style="font-size:12px;">Jean-Bernard Caron and Joe Moysiuk in the ROM palaeontogy lab room examining Titanokorys gainesi and Cambroraster falcatus (photo by Andrew Gregg/© Red Trillium)</span></em></div> </div> <p>Why some radiodonts evolved such a bewildering array of head carapace shapes and sizes is still poorly understood and was likely driven by a variety of factors, but the broad flattened carapace form in&nbsp;Titanokorys&nbsp;suggests this species was adapted to life near the seafloor.</p> <p>“These enigmatic animals certainly had a big impact on Cambrian seafloor ecosystems. Their limbs at the front looked like multiple stacked rakes and would have been very efficient at bringing anything they captured in their tiny spines towards the mouth. The huge dorsal carapace might have functioned like a plough,” added Caron, who is Moysiuk’s PhD adviser.</p> <p>All fossils in the study were collected around Marble Canyon in northern Kootenay National Park by successive ROM expeditions. Discovered less than a decade ago, this area has yielded a great variety of Burgess Shale animals dating back to the Cambrian period, <a href="/news/paleontologists-u-t-and-rom-discover-fossils-new-predatory-species-canadian-rockies">including a smaller, more abundant relative of&nbsp;Titanokorys&nbsp;named&nbsp;Cambroraster falcatus</a>&nbsp;in reference to its Millennium Falcon-shaped head carapace. According to the authors, the two species might have competed for similar bottom-dwelling prey.</p> <p>These and other Burgess Shale specimens will be showcased in a new gallery at the ROM, the Willner Madge Gallery, Dawn of Life, opening in December 2021.</p> <p>The Burgess Shale fossil sites are located within Yoho National Park and Kootenay National Park&nbsp;and are managed by Parks Canada. Parks Canada works with leading scientific researchers to expand knowledge and understanding of this key period of earth history and to share these sites with the world through award-winning guided hikes. The Burgess Shale was designated a UNESCO World Heritage Site in 1980 due to its outstanding universal value and is now part of the larger Canadian Rocky Mountain Parks World Heritage Site.</p> <p>Support for the research came from a Natural Sciences and Engineering Research Council of Canada Discovery Grant to Caron and a Vanier Canada Graduate Scholarship to Moysiuk.

And, thanks to the efforts of local history buffs, it was well on its way to bringing back an event that recalled the days when Windsor attracted famous civil rights activists and Motown stars to celebrate the anniversary of the abolition of slavery in most of the British colonies in 1834.</p> <p>The history – and recent revival – of Windsor’s Emancipation Day is being closely followed by <strong>Tonya Sutherland</strong>, who graduated from the Ƶ with a master’s degree in museum studies this year. Building on research for her 2018 capstone project,&nbsp;Sutherland and two other women from the Toronto area – retired teacher Catherine MacDonald and actor and producer Audra Gray – sought to bring this chapter of Black Canadian history to a wider audience.&nbsp;</p> <p>In the 1950s and early1960s, hundreds of thousands of people would arrive in Windsor for the multi-day festivities that took place the first weekend in August. They heard from figures like Martin Luther King Jr., Rosa Parks, Adam Clayton Powell Jr. and Eleanor Roosevelt – and watched the Supremes, Stevie Wonder and the Temptations,&nbsp;who&nbsp;crossed the Detroit River to perform at Windsor’s Jackson Park. But by the late 1960s, Windsor’s Emancipation Day festivities had begun to lose steam.</p> <p>“These celebrations were some of the biggest in North America, but they didn’t remain in people’s consciousness,” says Sutherland. “It’s a bit of a shame how they’ve been mostly forgotten.”</p> <p>But efforts are underway&nbsp;to make Emancipation Day a big deal again. When Windsor’s Emancipation Day Committee announced it was cancelling this year’s events, it also said it was planning for an significant event in&nbsp;2021.</p> <p>In the meantime, the Royal Ontario Museum in Toronto will mark Emancipation Day <a href="https://www.rom.on.ca/en/whats-on/emancipation-day-canadas-past-present-future">with a special ROM Connects talk moderated by Sutherland on Aug.&nbsp;5</a>, which follows an earlier talk given this month.</p> <p>Working under the umbrella of the Jackson Park Project, named for the park where the Emancipation Day celebrations were held in Windsor, Sutherland’s goal is to create a digital archive of historical material.</p> <p>As for Sutherland’s partners in the project, MacDonald is aiming to create&nbsp;educational resources for use in classrooms that would be hosted by the digital archive while Gray wants to produce a drama television series based on the annual festivities as well as a documentary. The documentary&nbsp;would chronicle both the team’s behind-the-scenes journey and a proposal before Parliament to formally recognize Emancipation Day nationally (<a href="https://www.ontario.ca/laws/statute/08e25">Ontario officially&nbsp;recognized the day in 2008</a>).</p> <p>“Audra was watching TV one day and came across this documentary, <em>The Greatest Freedom Show on Earth</em>. It was a larger history of Emancipation Day, somewhat focused on Windsor, but with a broader view,” says Sutherland. “She wondered why she had never heard of it.”</p> <p>Thinking it a story worth dramatizing, Gray linked up with MacDonald, her former teacher who was also interested in Canada’s Black history. MacDonald’s husband mentioned the project to his co-worker, Sutherland’s father, who in turn told his daughter about it.</p> <p>“I tend to get really invested in the personal element of history,” says Sutherland who also&nbsp;earned an undergraduate degree in English and history from U of T in 2016. That interest caused her friends to suggest she might want to check out the Faculty of Information’s museum studies program. The idea resonated with Sutherland, who had also been inspired watching the TV program&nbsp;<em>Mysteries at the Museum</em>.&nbsp;</p> <p>During their first research trip to Windsor in 2018, Sutherland, MacDonald and Gray spent a week researching and filming. Irene Moore Davis, president of the Essex County Black Historical Research Society, shared a wealth of information with the visitors. “While we say this is a history that’s not known to a broader audience, people from Windsor – whose families were involved&nbsp;– are very aware,” says Sutherland. “Irene has been really key to our project because she has quite a large collection of family history including boxes of documents. Her family was very involved in Emancipation Day.”</p> <p>While in Windsor, Sutherland visited the University of Windsor archives, looked at hundreds of photographs&nbsp;and examined the programs printed annually, which typically included a letter from the mayor of Windsor and sometimes featured messages from prominent speakers. “From magazines, you could see who was buying ad space and supporting the celebrations,” she says, adding that the documents helped with her primary research.</p> <p>Sutherland&nbsp;digitized the materials as part of her capstone project with the goal of creating a permanent digital archive. “I’ve learned all the things that go into creating an archive and a digital archive,” she says. “The more I learn, the more it teaches me what I don’t know.”</p> <p>That also goes for Black Canadian history, says Sutherland, who adds that Canadians often don’t know what became of the people who arrived in places like Windsor via the Underground Railroad. “Was everything amazing? Did they face racism and struggle?”</p> <p>The holes in our knowledge “speak to a larger unknowing,” she says. “This whole thing has been extremely eye-opening to me.”</p> <p>MacDonald says the history of Windsor’s Emancipation Day is a perfect subject for teaching because it is so multi-faceted. “It’s the story of Canada and the Black diaspora. It’s the story of English and French, and the story of Canada and the U.S. It’s the story of two cities.”</p> <p>Black families were often divided between Detroit and Windsor with cousins walking across the frozen Detroit River in winter and holding large family get-togethers at Emancipation Day events in the summer. A Detroit historian, Kimberly Simmons, has spent more than a decade trying to get the Detroit River declared a UNESCO World Heritage site for the role it played in the underground railroad.</p> <p>Meanwhile Sutherland, MacDonald and Gray continue to move forward on their Windsor projects. The teaser for Gray’s documentary debuted last summer at Emancipation Day. MacDonald is working with local Black educators, members of Windsor’s Black historical society and the Ontario Black History Society to produce lesson plans. And Sutherland has produced a digital archive feasibility report as her capstone project in museum studies.</p> <p>In some ways, the work they are doing emulates that done almost a century ago by Windsor citizens. In 1932, they, too, decided that they wanted to build up their small Emancipation Day celebrations into a much bigger event – and eventually turned their vision into reality.&nbsp;</p> <p>Despite COVID-19, the work behind the scenes on bringing Emancipation Day to a wider audience&nbsp;continues. “We’re now trying to seek out and establish viable and more stable sources of funding,” Sutherland says.</p> <p>&nbsp;</p> </div> <div class="field field--name-field-news-home-page-banner field--type-boolean field--label-above"> <div class="field__label">News home page banner</div> <div class="field__item">Off</div> </div> Thu, 30 Jul 2020 13:32:09 +0000 Christopher.Sorensen 165433 at U of T paleontologists find traces of sabre-toothed cat in Medicine Hat /news/u-t-paleontologists-find-traces-sabre-toothed-cat-medicine-hat <span class="field field--name-title field--type-string field--label-hidden">U of T paleontologists find traces of sabre-toothed cat in Medicine Hat</span> <div class="field field--name-field-featured-picture field--type-image field--label-hidden field__item"> <img loading="eager" srcset="/sites/default/files/styles/news_banner_370/public/Ashley%204.jpg?h=afdc3185&amp;itok=64fxS4EE 370w, /sites/default/files/styles/news_banner_740/public/Ashley%204.jpg?h=afdc3185&amp;itok=edFTtJSO 740w, /sites/default/files/styles/news_banner_1110/public/Ashley%204.jpg?h=afdc3185&amp;itok=193Y-1T1 1110w" sizes="(min-width:1200px) 1110px, (max-width: 1199px) 80vw, (max-width: 767px) 90vw, (max-width: 575px) 95vw" width="740" height="494" src="/sites/default/files/styles/news_banner_370/public/Ashley%204.jpg?h=afdc3185&amp;itok=64fxS4EE" alt="Ashley Reynolds holds the Smilodon fatalis metacarpal from Medicine Hat, Alberta"> </div> <span class="field field--name-uid field--type-entity-reference field--label-hidden"><span>davidlee1</span></span> <span class="field field--name-created field--type-created field--label-hidden"><time datetime="2019-10-04T08:41:17-04:00" title="Friday, October 4, 2019 - 08:41" class="datetime">Fri, 10/04/2019 - 08:41</time> </span> <div class="clearfix text-formatted field field--name-field-cutline-long field--type-text-long field--label-above"> <div class="field__label">Cutline</div> <div class="field__item">U of T PhD student Ashley Reynolds, lead author of the study, holds the Smilodon fatalis metacarpal from Medicine Hat.

The fossil was identified during a review of collections at the ROM.</p> <p>The study also documents bone specimens from three other types of cat from Medicine Hat, Alta., including the American lion (<em>Panthera atrox</em>), a lynx or bobcat (<em>Lynx sp.</em>), and what may be the most southerly record of the cave lion (<em>Panthera cf. Panthera spelaea</em>), which was previously only known in North America from fossils found in Alaska and the Yukon.</p> <p>“Knowing now that Smilodon’s range extended this far north in Canada tells us a lot more about Pleistocene ecosystems and how they changed over time,” said&nbsp;<strong>Ashley Reynolds</strong>, a PhD student in the department of ecology and evolutionary biology in the Faculty of Arts &amp; Science at U of T, who is based at the ROM.</p> <p><img class="migrated-asset" src="/sites/default/files/Canadian%20Smilodon%20Reconstruction.jpg" alt="Illustration of "></p> <p><em>Illustration of&nbsp;Smilodon fatalis&nbsp;(Henry Sutherland Sharpe)</em></p> <p>“This allows us to learn how plant and animal communities responded to changes in the past, and even how they may respond to human-related changes today and in the future,” Reynolds said.</p> <p>Supersized cats like Smilodon and the American lion went extinct the same time their prey did, at the end of the Pleistocene epoch, around 11,000 years ago.</p> <p>“These few bones show that at least three large cat species lived in western Canada during the Ice Age” says <strong>Kevin Seymour</strong>, co-author and assistant curator, vertebrate paleontology, at the ROM.</p> <p>“This sharply contrasts with today when we have only one large cat in Canada, the mountain lion or cougar, which is smaller than the other big cats that roamed Canada during the Pleistocene.”</p> <p>The mountain lion’s larger Ice Age cousins, including Smilodon, would have hunted large herbivores that were also present at the time, including camels, horses, giant ground sloths and young mammoths and mastodons, whereas the mountain lion today hunts mainly deer.</p> <p>“Smilodon is best known from tar pit deposits in California and South America, so it’s both exciting and surprising to find evidence of this iconic sabre-toothed predator in Canada,” says co-author <strong>David Evans</strong>, an associate professor in the department of ecology and evolutionary biology and Reynolds's PhD supervisor. Evans is also the James and Louise Temerty Endowed Chair of Vertebrate Paleontology at the ROM.</p> <p>Reynolds’s interest in the comparative anatomy of big cats has led her to specialize in the study of pre-historic cats for her PhD. “I was looking through the ROM’s collections one day to see what we had and was very surprised to find fossils from Alberta labelled as Smilodon,” she says. “I knew then that we had something really cool.”</p> <p><img class="migrated-asset" src="/sites/default/files/Ashleys%20hand.jpg" alt></p> <p><em>Ashley Reynolds holds the Smilodon fatalis metacarpal from Medicine Hat (photo by Danielle Dufault/ROM)</em></p> <p>The fossils held at the ROM were collected in the late 1960s by U of T paleontologist <strong>C.S. Churcher</strong> and colleagues in the area around Medicine Hat. This latest research confirms the species to which the bones belonged to.</p> <p>This past summer, Evans and Reynolds followed up by leading a team of graduate students to explore the Ice Age deposits and revisit the fossil sites in Medicine Hat.</p> <p>The iconic Smilodon has captured the public’s imagination in pop culture. Fans of the big cat may know the animal as Diego from the 2002 movie <em>Ice Age</em>, or from the end credits of <em>The Flintstones </em>cartoon that shows Fred unceremoniously putting their sabre-toothed cat, Baby Puss, out of the house every night.</p> <p>The research was supported by the Natural Sciences and Engineering Research Council of Canada.</p> <p>&nbsp;</p> </div> <div class="field field--name-field-news-home-page-banner field--type-boolean field--label-above"> <div class="field__label">News home page banner</div> <div class="field__item">Off</div> </div> Fri, 04 Oct 2019 12:41:17 +0000 davidlee1 159391 at Researchers discover tiny, 500-million-year-old predecessor to scorpions and spiders /news/researchers-discover-tiny-500-million-year-old-predecessor-scorpions-and-spiders <span class="field field--name-title field--type-string field--label-hidden">Researchers discover tiny, 500-million-year-old predecessor to scorpions and spiders</span> <div class="field field--name-field-featured-picture field--type-image field--label-hidden field__item"> <img loading="eager" srcset="/sites/default/files/styles/news_banner_370/public/Image-resized---RL.jpg?h=afdc3185&amp;itok=V7kccFco 370w, /sites/default/files/styles/news_banner_740/public/Image-resized---RL.jpg?h=afdc3185&amp;itok=TNJP5wvq 740w, /sites/default/files/styles/news_banner_1110/public/Image-resized---RL.jpg?h=afdc3185&amp;itok=gerD8BbH 1110w" sizes="(min-width:1200px) 1110px, (max-width: 1199px) 80vw, (max-width: 767px) 90vw, (max-width: 575px) 95vw" width="740" height="494" src="/sites/default/files/styles/news_banner_370/public/Image-resized---RL.jpg?h=afdc3185&amp;itok=V7kccFco" alt="photo of Mollisonia plenovenatrix"> </div> <span class="field field--name-uid field--type-entity-reference field--label-hidden"><span>Christopher.Sorensen</span></span> <span class="field field--name-created field--type-created field--label-hidden"><time datetime="2019-09-12T11:34:23-04:00" title="Thursday, September 12, 2019 - 11:34" class="datetime">Thu, 09/12/2019 - 11:34</time> </span> <div class="clearfix text-formatted field field--name-field-cutline-long field--type-text-long field--label-above"> <div class="field__label">Cutline</div> <div class="field__item">Mollisonia plenovenatrix preserved in dorsal view, showing the large eyes, walking legs and the small chelicerae at the front (photo by Jean-Bernard Caron) </div> </div> <div class="field field--name-field-author-reporters field--type-entity-reference field--label-hidden field__items"> <div class="field__item"><a href="/news/authors-reporters/arts-science-news-staff" hreflang="en">Arts &amp; Science news staff</a></div> </div> <div class="field field--name-field-topic field--type-entity-reference field--label-above"> <div class="field__label">Topic</div> <div class="field__item"><a href="/news/topics/breaking-research" hreflang="en">Breaking Research</a></div> </div> <div class="field field--name-field-story-tags field--type-entity-reference field--label-hidden field__items"> <div class="field__item"><a href="/news/tags/earth-sciences" hreflang="en">Earth Sciences</a></div> <div class="field__item"><a href="/news/tags/ecology-evolutionary-biology" hreflang="en">Ecology &amp; Evolutionary Biology</a></div> <div class="field__item"><a href="/news/tags/faculty-arts-science" hreflang="en">Faculty of Arts &amp; Science</a></div> <div class="field__item"><a href="/news/tags/global" hreflang="en">Global</a></div> <div class="field__item"><a href="/news/tags/research-innovation" hreflang="en">Research &amp; Innovation</a></div> <div class="field__item"><a href="/news/tags/royal-ontario-museum" hreflang="en">Royal Ontario Museum</a></div> </div> <div class="clearfix text-formatted field field--name-body field--type-text-with-summary field--label-hidden field__item"><p>Paleontologists&nbsp;working on the world-renowned Burgess Shale have revealed a new species named <em>Mollisonia plenovenatrix</em>, which they describe as the oldest member of a group of animals called chelicerates. The discovery places the origin of this vast group of animals – over 115,000 species including horseshoe crabs, scorpions and spiders – to a time more than 500 million years ago, near the beginning of the Cambrian Period.</p> <p><a href="https://www.nature.com/articles/s41586-019-1525-4">The findings were published this week</a> in <em>Nature</em>.</p> <p><em>Mollisonia plenovenatrix</em> would have been a fierce predator – for its size. As big as a thumb, the creature boasted a pair of large egg-shaped eyes and a “multi-tool head” with long walking legs, as well as numerous pairs of limbs that could altogether sense, grasp, crush and chew.</p> <p>But, most importantly, the new species also had a pair of tiny pincers in front of its mouth, called chelicerae. These appendages give rise to the name chelicerates and are used to kill, hold and, sometimes, cut their prey.</p> <p><img class="migrated-asset" src="/sites/default/files/mollisonia-web-embed.jpg" alt></p> <p><em>Reconstruction of Mollisonia plenovenatrix (image courtesy of Joanna Liang, Royal Ontario Museum)</em></p> <p>“Before this discovery, we couldn’t pinpoint the chelicerae in other Cambrian fossils, although some of them clearly have chelicerate-like characteristics,” says <strong>Cédric Aria</strong>, lead author of the <em>Nature</em> study and a recent graduate of the PhD program in the Ƶ’s department of ecology and evolutionary biology in the Faculty of Arts &amp; Science.</p> <p>“This key feature, this ‘coat of arms’ of the chelicerates, was still missing.”</p> <p>Other features of this fossil, including back limbs likened to gills, further suggest that <em>Mollisonia’s</em> body already resembled those of modern species and was not some primitive version of a chelicerate.</p> <p>“Chelicerates have what we call either book gills or book lungs,” explains Aria, a member of the Royal Ontario Museum’s Burgess Shale expeditions since 2012 and currently a post-doctoral fellow at the Nanjing Institute of Geology and Palaeontology in China.</p> <p>“They are respiratory organs made of many collated thin sheets, like a book. This greatly increases surface area and therefore gas exchange efficiency. <em>Mollisonia</em> had appendages made up with the equivalent of only three of these sheets, which probably evolved from simpler limbs.”</p> <p><img class="migrated-asset" src="/sites/default/files/Cedric-Marble-Canyon-2014-web-embed.jpg" alt></p> <p><em>U of T alumnus Cédric Aria at the main Marble Canyon quarry site in Canada’s Kootenay National Park during the summer of 2014 (photo by Jean-Bernard Caron)</em></p> <p>Aria and co-author <strong>Jean-Bernard Caron</strong>, the curator of invertebrate palaeontology at the ROM and an associate professor at U of T’s department of Earth sciences,&nbsp;believe that <em>Mollisonia</em> hunted close to the sea floor – a type of behaviour called benthic predation – thanks to its well-developed walking legs. Because <em>Mollisonia</em> is so modern-looking, chelicerates seem therefore to have prospered quickly, filling in an ecological niche that was otherwise left poorly attended by other arthropods at that time. The authors conclude that the origin of the chelicerates must lie even earlier within the Cambrian, when the heart of the “explosion” really took place.</p> <p>“Evidence is converging towards picturing the Cambrian explosion as even swifter than what we thought,” says Aria.</p> <p>“Finding a fossil site like the Burgess Shale at the very beginning of the Cambrian would be like looking into the eye of the cyclone.”</p> </div> <div class="field field--name-field-news-home-page-banner field--type-boolean field--label-above"> <div class="field__label">News home page banner</div> <div class="field__item">Off</div> </div> Thu, 12 Sep 2019 15:34:23 +0000 Christopher.Sorensen 158201 at Three U of T faculty appointed members of the Royal Society of Canada’s college for new scholars /news/three-u-t-faculty-appointed-members-royal-society-canada-s-college-new-scholars <span class="field field--name-title field--type-string field--label-hidden">Three U of T faculty appointed members of the Royal Society of Canada’s college for new scholars</span> <div class="field field--name-field-featured-picture field--type-image field--label-hidden field__item"> <img loading="eager" srcset="/sites/default/files/styles/news_banner_370/public/Untitled-1_12.jpg?h=3fcbca33&amp;itok=XdxlU6L9 370w, /sites/default/files/styles/news_banner_740/public/Untitled-1_12.jpg?h=3fcbca33&amp;itok=qefH7aj5 740w, /sites/default/files/styles/news_banner_1110/public/Untitled-1_12.jpg?h=3fcbca33&amp;itok=_vMuAzmj 1110w" sizes="(min-width:1200px) 1110px, (max-width: 1199px) 80vw, (max-width: 767px) 90vw, (max-width: 575px) 95vw" width="740" height="494" src="/sites/default/files/styles/news_banner_370/public/Untitled-1_12.jpg?h=3fcbca33&amp;itok=XdxlU6L9" alt="From left to right Daniel de Carvalho, david evans, and jean-philippe julien"> </div> <span class="field field--name-uid field--type-entity-reference field--label-hidden"><span>perry.king</span></span> <span class="field field--name-created field--type-created field--label-hidden"><time datetime="2019-09-10T12:31:36-04:00" title="Tuesday, September 10, 2019 - 12:31" class="datetime">Tue, 09/10/2019 - 12:31</time> </span> <div class="clearfix text-formatted field field--name-field-cutline-long field--type-text-long field--label-above"> <div class="field__label">Cutline</div> <div class="field__item">From left to right: U of T researchers Jean-Philippe Julien, David Evans and Daniel De Carvalho are being recognized for demonstrating a high level of achievement in their careers to date (all photos by Perry King)</div> </div> <div class="field field--name-field-author-reporters field--type-entity-reference field--label-hidden field__items"> <div class="field__item"><a href="/news/authors-reporters/perry-king" hreflang="en">Perry King</a></div> </div> <div class="field field--name-field-topic field--type-entity-reference field--label-above"> <div class="field__label">Topic</div> <div class="field__item"><a href="/news/topics/our-community" hreflang="en">Our Community</a></div> </div> <div class="field field--name-field-story-tags field--type-entity-reference field--label-hidden field__items"> <div class="field__item"><a href="/news/tags/awards" hreflang="en">Awards</a></div> <div class="field__item"><a href="/news/tags/biochemistry" hreflang="en">Biochemistry</a></div> <div class="field__item"><a href="/news/tags/ecology-environmental-biology" hreflang="en">Ecology &amp; Environmental Biology</a></div> <div class="field__item"><a href="/news/tags/faculty-arts-science" hreflang="en">Faculty of Arts &amp; Science</a></div> <div class="field__item"><a href="/news/tags/faculty-medicine" hreflang="en">Faculty of Medicine</a></div> <div class="field__item"><a href="/news/tags/hospital-sick-children" hreflang="en">Hospital for Sick Children</a></div> <div class="field__item"><a href="/news/tags/immunology" hreflang="en">Immunology</a></div> <div class="field__item"><a href="/news/tags/princess-margaret-hospital" hreflang="en">Princess Margaret Hospital</a></div> <div class="field__item"><a href="/news/tags/research-innovation" hreflang="en">Research &amp; Innovation</a></div> <div class="field__item"><a href="/news/tags/royal-ontario-museum" hreflang="en">Royal Ontario Museum</a></div> </div> <div class="clearfix text-formatted field field--name-body field--type-text-with-summary field--label-hidden field__item"><p>One researcher wants to beat cancer.

I’m really happy.”</p> <p>The Brazil-born researcher’s work focuses on epigenetics, or the changes brought on by modification of gene expression, and better understanding the mechanisms behind tumour growth and translating this knowledge into more efficient approaches for therapy.</p> <p>Some of his research has&nbsp;<a href="/news/research-uncovers-possible-drug-treatment-incurable-brain-cancer">uncovered possible cancer treatments</a>.</p> <p>“When we’re thinking about cancer in general, [we’re thinking about] how can we beat cancer – make new therapies and so on,” De Carvalho says.</p> <p>His lab is focused on early detection since cancers evolve, cell mutations occur within patients and, in some cases, can become metastatic. His team wants to get ahead of such threats.</p> <p>“If you detect early, it’s much easier to treat. But&nbsp;it’s very difficult to detect. Later on, it’s very easy to detect but it’s very difficult to treat,” says De Carvalho. “We’re trying to break this in a way that can be more useful to the patient.”</p> <p>The opportunity to work with researchers across multiple disciplines, from immunology to computational biology, helps keep De Carvalho motivated.</p> <p>“I have to trust and believe everyone here,” he says. “I’m really hands off so it gives space to trainees – post-docs, visiting scientists, PhD students – so they’re all working together.”</p> <p>As he joins the Royal Society of Canada, De Carvalho wants to spread the idea that curiosity-driven research like his needs broad support.</p> <p>“We need to figure out ways … to create an ecosystem in Canada where science can move faster from basic science to the clinical side.”</p> <p><img class="migrated-asset" src="/sites/default/files/0J5A0974.jpg" alt></p> <h4>Jean-Philippe Julien</h4> <p>Julien, an assistant professor in the departments of biochemistry and immunology in the Faculty of Medicine and a scientist at the SickKids Research Institute, studies how the immune system works and harnesses that information to design interventions, including vaccines.</p> <p>In particular, Julien investigates B cells, which produce antibodies that neutralize invading pathogens like bacteria, viruses and parasites.</p> <p>With a focus on infectious diseases – in recent years, his team has been unpacking the complexities of malaria and HIV – his lab seeks to understand health at an atomic scale.</p> <p>“We think that if you understand the molecular basis of immune responses, you can intervene more precisely,” says Julien.</p> <p>His lab, which has recently been leading several research fronts toward the development of a malaria vaccine, partners with numerous collaborators. They include research sites with unique samples from individuals exposed to infectious disease, and from clinical trial sites that offer opportunities for researchers to learn how humans respond to vaccine candidates.</p> <p>“We learn from the human response as much as we can – natural settings, but also in testing new technologies and interrogating them at the molecular level,” says Julien, who received his PhD from U of T in 2010.</p> <p>Julien says his membership in the College of New Scholars, Artists and Scientists is a reflection of his team’s success – not only his own. He also sees it as an opportunity to grow as a thought leader.</p> <p>“The biggest aspect to it, for me, is the ability to be part of an organization that mentors junior colleagues – not just in science and research but also in leadership and outreach,” he says. “I really look forward to that.”</p> <p>As for the future, Julien says he’s focused on gaining a better understanding of the molecular basis of disease to guide the development of next-generation biomedical interventions.</p> <p><img class="migrated-asset" src="/sites/default/files/0J5A0982.jpg" alt></p> <h4>David Evans</h4> <p>An associate professor in the department of ecology and evolutionary biology in the Faculty of Arts &amp; Science who oversees dinosaur research at the Royal Ontario Museum, Evans studies the Cretaceous Period to understand Earth’s biodiversity crisis today.</p> <p>The paleontologist is trying to build the fossil record from that “data-rich” period – the one before the mass extinction event 66 million years ago wiped out over 75 per cent of species on Earth, including all the non-avian dinosaurs.</p> <p>Speaking at his office at the ROM, Evans says his work focuses on fundamental questions about life on Earth at that time. In turn, the data contributes to ecological models that test the resilience of different organisms to extinction, and ecosystems to collapse.</p> <p>Such work will help us understand the “causes and consequences of mass extinctions,” Evans says. His work takes into account what makes a robust ecosystem, what species are more likely to survive an extinction event and what happens to ecosystems as a result of habitat destruction and sea level and climate change.</p> <p>“We have a lot of these particular scenarios that have played out in Earth’s history that we can go back to and study to see what the particular consequences of those types of changes have been on the Earth’s biota through time,” says Evans, who joined the ROM in 2007.</p> <p>From “boots on the ground” fossil digs to collaborations with global research teams, Evans has personally been involved with the discovery of 11 new dinosaur species in the last six years, including&nbsp;<a href="/news/u-t-paleontologists-uncover-76-million-year-old-armoured-dinosaur-skull">a 76-million-year-old armoured dinosaur in 2017</a>.</p> <p>But there is still work to be done. Only about 900 dinosaur species have been verified in the 150 million years of recorded dinosaur history, says Evans. That pales in comparison to the number of known bird, mammal and reptile species in the present day.</p> <p>“That’s what I tell a lot of the up-and-coming young paleontologists that I see here at the museum and around the world – that dinosaur discoveries are not running out anytime soon,” Evans says.</p> <p>“There will be generations and generations of new discoveries to be made and they can make them. We’re not even close to knowing everything.”</p> </div> <div class="field field--name-field-news-home-page-banner field--type-boolean field--label-above"> <div class="field__label">News home page banner</div> <div class="field__item">Off</div> </div> Tue, 10 Sep 2019 16:31:36 +0000 perry.king 157944 at U of T paleontologist David Evans takes the Globe and Mail on a dinosaur dig /news/u-t-paleontologist-david-evans-takes-globe-and-mail-dinosaur-dig <span class="field field--name-title field--type-string field--label-hidden">U of T paleontologist David Evans takes the Globe and Mail on a dinosaur dig </span> <div class="field field--name-field-featured-picture field--type-image field--label-hidden field__item"> <img loading="eager" srcset="/sites/default/files/styles/news_banner_370/public/IMG_8144.JPG?h=afdc3185&amp;itok=yve2X36T 370w, /sites/default/files/styles/news_banner_740/public/IMG_8144.JPG?h=afdc3185&amp;itok=TUykK0pc 740w, /sites/default/files/styles/news_banner_1110/public/IMG_8144.JPG?h=afdc3185&amp;itok=I_jUPcOO 1110w" sizes="(min-width:1200px) 1110px, (max-width: 1199px) 80vw, (max-width: 767px) 90vw, (max-width: 575px) 95vw" width="740" height="494" src="/sites/default/files/styles/news_banner_370/public/IMG_8144.JPG?h=afdc3185&amp;itok=yve2X36T" alt="David Evans at a dig site in Montana"> </div> <span class="field field--name-uid field--type-entity-reference field--label-hidden"><span>perry.king</span></span> <span class="field field--name-created field--type-created field--label-hidden"><time datetime="2019-08-19T13:03:33-04:00" title="Monday, August 19, 2019 - 13:03" class="datetime">Mon, 08/19/2019 - 13:03</time> </span> <div class="clearfix text-formatted field field--name-field-cutline-long field--type-text-long field--label-above"> <div class="field__label">Cutline</div> <div class="field__item">(photo courtesy of David Evans)</div> </div> <div class="field field--name-field-topic field--type-entity-reference field--label-above"> <div class="field__label">Topic</div> <div class="field__item"><a href="/news/topics/global-lens" hreflang="en">Global Lens</a></div> </div> <div class="field field--name-field-story-tags field--type-entity-reference field--label-hidden field__items"> <div class="field__item"><a href="/news/tags/dinosaurs" hreflang="en">Dinosaurs</a></div> <div class="field__item"><a href="/news/tags/ecology-evolutionary-biology" hreflang="en">Ecology &amp; Evolutionary Biology</a></div> <div class="field__item"><a href="/news/tags/faculty-arts-science" hreflang="en">Faculty of Arts &amp; Science</a></div> <div class="field__item"><a href="/news/tags/research-innovation" hreflang="en">Research &amp; Innovation</a></div> <div class="field__item"><a href="/news/tags/royal-ontario-museum" hreflang="en">Royal Ontario Museum</a></div> </div> <div class="clearfix text-formatted field field--name-body field--type-text-with-summary field--label-hidden field__item"><p>When paleontologist <strong>David Evans</strong> and his team discovered a triceratops skull in the fossil-rich Hell Creek Formation, the <em>Globe and Mail</em>&nbsp;was right along with them.</p> <p>Evans, an associate professor at the Ƶ’s department of ecology and evolutionary biology,&nbsp;<a href="http://www.theglobeandmail.com/arts/art-and-architecture/article-roms-palaeontology-team-heads-to-montanas-badlands-to-uncover/">walked a reporter through his team’s Hell&nbsp;Creek expedition</a> – a five-year project seeking Late Cretaceous period fossils in the mountainous region of Montana.
