Research Scientist, Palaeobiology
Jordan Mallon studies the evolution and ecology of dinosaurs.
- Evolutionary palaeoecology
- Functional morphology
- Postdoctoral Fellow, Canadian Museum of Nature, Ottawa, Ontario, 2013–2014
- Ph.D., University of Calgary, Calgary, Alberta, 2006–2012
- B.Sc., Carleton University, Ottawa, Ontario, 2001–2005.
Jordan Mallon's research focuses on dinosaur ecology, particularly on those factors that influenced dinosaur diversity leading up to the end-Cretaceous mass extinction. To this end, 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, U.S.A.
