Kathlyn Stewart collects and studies fossils of fish, bird and mammal bones from across Canada and Eastern Africa to better understand what life was like for these long-dead animals and what evolutionary forces shaped their existence. Her research provides insight into the environment of these creatures, including their interactions with humans.
Over the course of her 30 years as a palaeobiologist, Kathlyn has named 10 species of fossil fish, joined several fossil expeditions to eastern Africa, authored and edited numerous scientific papers and books, founded Canadian Zooarchaeology, which she continues to co-edit in addition to the journal Syllogeus, and held adjunct professorships at the Universities of Victoria, Toronto and Trent. She joined the Canadian Museum of Nature in 1991.
Main Research Projects
- Changing Faunas and Human Activities on the Canadian Northwest Coast for the Past 6000 Years.
- Vertebrate Evolution, Hominid Origins and Environmental Change in the Later Cenozoic Era.
- Adjunct Professor, University of Victoria
- Founder and Co-Editor, Canadian Zooarchaeology.
- Zooarchaeological identification (identification and/or analysis of subfossil or fossil bones by contract).

Cabinets, Cabinets Everywhere: The Sequel
Meteorites and fossil plant type specimens are among the first of the collections of the Geological Survey of Canada to be housed within our walls. It's the first part of an important move taking place in 2017. Continue reading
Cabinets, Cabinets Everywhere: Getting Ready to Welcome New Collections From Geological Survey of Canada
In 1842, Sir William Logan and his colleagues undertook a comprehensive geological survey of Canada. A great many of the specimens they collected are moving to the Canadian Museum of Nature. Palaeobiologist Kathlyn Stewart tells about the preparations that are underway to welcome these precious specimens.
