Femke Holwerda studies the diet of mosasaurs from the Bearpaw Formation in southern Alberta. The main aspect of Femke’s research is odontology (the study of teeth, and their structure and development). By examining fossilized mosasaur teeth and other marine animals, Femke will reconstruct a foodweb for mosasaurs from the Bearpaw Formation.
Research Interests
- Mosasaur diet
- Fossil teeth
- Jurassic sauropod palaeobiology and classification
- Sauropod evolutionary history
Professional Highlights
- Participated in fieldwork with the American Museum of Natural History in Wyoming.
- Conducted research at: the Museo Paleontológico Egidio Feruglio (Argentina); the Oxford University Museum of Natural History (United Kingdom); the Friedrich-Alexander University Erlangen-Nürnberg (Germany).
