Dr. Jack Horner

Talk Title: Dinosaurs were way cooler than anyone has ever imagined!

Jack received an honorary Ph.D. from the University of Montana, and holds several honorary degrees. In 1986 he was awarded a MacArthur Fellowship, and in 2013 Jack received the Romer-Simpson Medal by the Society of Vertebrate Paleontology. Jack’s vast research has been at the forefront of paleontological discoveries and revolutionizing the way the think of, view, and study dinosaurs. In 1979, Jack and Bob Makela described Maiasaura – consisting of eggs, young in nests, and adults all together, this was the critical discovery for understanding parental care in dinosaurs. Jack’s research strives to better understand dinosaurs through several avenues of ontogenetic, histologic, and stratigraphic research. Jack also serves as the scientific consultant for the Jurassic Park franchise, and his favorite dinosaurs are sauropods.

Dr. Phil Currie

Talk Title: The dromaeosaurids (‘raptors’) of Alberta

Phil received his Ph.D. from McGill University, and has received numerous professional accolades including: elected to the Royal Society of Canada (1999), awarded the Alberta Order of Excellence (2010), gold medal winner by the Canadian Geographical Society (2012), and the Romer-Simpson Medal by the Society of Vertebrate Paleontology (2017). Phil is a leading expert in theropod dinosaurs, and has scoured the Canadian, Mongolian, and Argentinian (just to name a few!) badlands on the hunt for these carnivorous dinosaurs. Phil was a pivotal member of what would become the Royal Tyrrell Museum of Paleontology. In 2015, Phil’s vast achievements to Canadian paleontology resulted in a museum being named in his honor – the Phillip J. Currie Dinosaur Museum.

Dr. Eva Koppelhus

Eva is Assistant Professor and Curator of Paleobotany and Palynology at The University of Alberta. Eva’s interest in paleobotany (the study of fossil plants) and palynology (the study of fossilized spores and pollen) goes way back into the Cretaceous Period (135 to 64 million years ago). Many of her research projects have taken place in Argentina, Australia, China, Europe, Indonesia, Japan, Madagascar, Mongolia, New Zealand, South Korea, South Africa, and the U.S.


Dr. David Evans

Talk Title: The Raptor Dinosaurs of Montana

David received his Ph.D. from the University of Toronto, and he is the Temerty Chair in Vertebrate Palaeontology and oversees dinosaur research at the Royal Ontario Museum. David is is also an Associate Professor in the Department of Ecology and Evolutionary Biology at the University of Toronto. David’s research focuses on the evolution, ecology and diversity of dinosaurs, and their relationship to environmental changes leading up to the end Cretaceous mass extinction event. Active in the field, he has participated in expeditions all over the world, including the Africa, Mongolia, and Canada, and has helped discover 10 new dinosaur species in the last five years- including the remarkable horned dinosaur Wendiceratops from southern Alberta, and the wickedly armoured Zuul named after the Ghostbusters movie monster.

Dr. Don Brinkman

Talk Title: Non-marine teleost fish assemblages from the Late Cretaceous of the Western Interior of North America – evidence from vertebrate microfossil localities

Don studies how ancient animals, and turtles in particular, lived in their environments during the time of the dinosaurs. By comparing turtle specimens from Asia and North America, he investigates why some species lived where they did, what unique traits helped them to survive, and how environmental conditions affected them. This research allows Don to determine the conditions of life during specific periods of history, and why some species survived catastrophic events, while others did not.

Dr. Ray Rogers

Talk Title: Conceptualizing the Stratigraphy of the Upper Cretaceous (Campanian) Judith River Formation in central Montana and Beyond

Ray received his Ph.D. from the University of Chicago, and is a preeminent expert on sedimentary geology and vertebrate taphonomy (Ray literally wrote the book on this subject, entitle “Bonebeds: Genesis, Analysis, and Paleobiological Significance”). Ray’s work on rocks and dinosaurs (and dinosaur precursors) has taken him from the Cretaceous foreland basin of Montana, the Triassic Ischigualasto Basin of Argentina, the Triassic-Jurassic Karoo-equivalent rocks of southern Zimbabwe, and the Mahajanga Basin of Madagascar.

Dr. Thomas Carr

Talk Title: Campanian tyrannosaurids of Alberta and Montana

Thomas received his Ph.D. from the University of Toronto, and is a preeminent expert on tyrannosaurs. Studying their growth and development, Thomas strives to shed light on the intimate life history of the “Tyrant Kings”. Thomas’ research on tyrannosaur growth is persistently at the forefront of active scientific debate. Understanding how the bones changed shaped through growth in the famed Tyrannosaurus, Thomas has shown that the previously recognized ‘Nannotyrannus‘ is in fact just an immature Tyrannosaurus (though this is still hotly debated). In addition to tyrannosaurs, Thomas also researches archosaur craniofacial anatomy, the integration of ontogenic and phylogenetic data in paleontology, and sauropod ontogeny (I kid you not!).

Dr. Liz Freedman Fowler

Talk Title: My Crest is Bigger Than Yours: Evolution of Display Structures in Brachylophosaurins (Duck-billed Dinosaurs)

Liz received her Ph.D. from Montana State University (Go ‘Cats!) with Dr. Jack Horner, and her research focuses on the evolution and ontogenetic growth of hadrosaur (duck-billed) dinosaurs in the Late Cretaceous of North America.

Dr. Denver Fowler

Talk Title: “Dannyceratops” from Rudyard, Montana, and its significance for Chasmosaurines: evolution of long frilled horned dinosaurs during the Judithian (and beyond!)

Denver received his Ph.D. from Montana State University (Go ‘Cats!) with Dr. Jack Horner, and his research largely focuses on how dinosaurs lived. Ranging from how “raptor” dinosaurs used their sickle-like claws to pin down prey, the biggest dinosaur in North America, sauropod ontogeny and how they used their feet for nest building, Triceratops ontogeny and how it evolved throughout the Hell Creek Formation, to even how a Tyrannosaurus ate a Triceratops, Denver’s areas of research and expertise span a variety of fascinating topics. Denver is the Curator at the Badlands Dinosaur Museum at the Dickinson Museum Center in Dickinson, ND – in addition to many new displays, the Badlands Dinosaur Museum is doing tons of amazing Montana fieldwork, so go check out their great discoveries!

Dr. Michael Ryan

Talk Title: A new centrosaurine ceratopsid from the Oldman Formation of Alberta

Emily’s research primarily focuses on Cretaceous palaeoecology, involving the study of plant and animals fossils, geology and sedimentology in order to understand ancient ecosystems. In 2008, she began her PhD at McGill University under the supervision of Dr. Hans Larsson, exploring pre-extinction biodiversity trends immediately prior to the K-Pg extinction in Saskatchewan. Emily has published several papers and numerous conference abstracts of Ediacaran and Cretaceous paleontology. She was a recipient of an NSERC CGS-D Scholarship, as well as a two-time winner of the Geological Association of Canada – Paleontology Division’s Thomas E. Bolton Best Student Paper award.  She enjoys public outreach, teaching and fieldwork, often with the help of her dog, Aster.

Dr. Jordan Mallon

Talk Title: The first Canadian dinosaur finds

Jordan received his Ph.D. from the University of Calgary, and is a Research Scientist and Head of Palaeobiology at the Canadian Museum of Nature in Ottawa, Canada. His studies focus on dinosaur systematics and palaeoecology, although he is known to occasionally work on other Mesozoic reptiles as well. Jordan studies dinosaur feeding adaptations, community ecology and geographic distribution. By carefully examining feeding posture, skull and beak shape, jaw function and tooth wear, he has shown that diverse plant-eating dinosaurs living in Alberta 75 million years ago were able to coexist as a result of their varied dietary specializations. Jordan is also interested in horned dinosaurs, which were among the most successful animals of their time. He investigates their lifestyles, growth, and evolution to determine what allowed them to thrive during the Late Cretaceous Period. Jordan recently published on a showy new horned-dinosaur species from Montana named Spiclypeus.

Taia Wyenberg-Henzler

Talk Title: Ontogenetic niche shifts in megaherbivorous dinosaurs from the Late Cretaceous of North America

Taia is currently an M.Sc. student with Dr. Jordan Mallon jointly at Carleton University and the Canadian Museum of Nature. For her thesis, Taia is researching ontogenetic niche shifts in large herbivorous dinosaurs. Additionally, Taia has worked on the stratigraphy, biostratigraphy and X-ray fluorescence analysis of mudstone and heterolithic facies in the Dinosaur Park Formation, from Dinosaur Provincial Park in Alberta, the paleoecology from trilobite heads in the Lower Cambrian of Fort Steele, British Columbia, and the stratigraphy and ichnology of coastal plain heterolithic and mudstone facies of the Cambrian Dinosaur Park to Bearpaw transgression of Southern Alberta.

Anthony Maltese

Talk Title: Preparation and restoration methods of ceratopsian skulls from Fergus County, Montana

Working with sauropod dinosaurs from the Black Hills region of Wyoming, Anthony started his career in 1997 in “The Pit” at the University of Kansas. Since then he’s conducted field work in Mexico, Portugal, The Netherlands, and South Korea as well as all over the western United States while working for the Rocky Mountain Dinosaur Resource Center/Triebold Paleontology Inc. in Woodland Park, Colorado. Focusing intensely on the Niobrara Chalk of Kansas, Hell Creek Formation of South Dakota and Judith River Formation of Montana, he’s assisted with researchers worldwide in recovering new specimens of animals. This field season will be his 14th summer in the Judith River Formation. Anthony has participated in naming 4 species of fish (Bonnerichthys gladius and all 3 species of Rhinconichthys), engaged in lively presentations on fossil ethics and legality at SVP and EAVP, and has led SVP workshops on field safety.  In his free time he volunteers on the board of directors of several outdoor organizations and city commissions for Open Space management, is a certified outdoor crew leader, and most importantly spoils his golden retriever Annabelle (named after a Camarasaurus, KUVP 129716).

David Trexler

Talk Title: Taphonomy of an Unusual Multiple-Individual Ceratopsian Bonebed in the Lower Judith River Formation, North-Central Montana

Dave Trexler received his M.Sc. degree from the University of Calgary where he studied the famed Montana hadrosaur Maiasaura. He and his family have been heavily involved in dinosaur nesting behavior research (Dave’s mother found the very first baby dinosaurs in a nest – a discovery that would become the famed Egg Mountain locality). Since 1995, Dave has worked with the Two Medicine Dinosaur Center in Bynum, Montana. Dave’s love of dinosaurs is matched only by his love of flying, and he has spent many hours mapping possible dinosaur-bearing outcrops from the air!
