Originally from Paris, France, by way of New York City, Julien Divay received his B.Sc. from Liverpool John Moores University and his M.Sc. from the University of Bristol. He moved back to North America to obtain his Ph.D. from the University of Alberta and joined the Royal Tyrrell Museum’s Research Program in spring 2015. Julien’s main research interest combines the reconstruction of North American freshwater fish faunas and the development of the use of microvertebrates (small, disarticulated fossil bones) in palaeoichthyology (the study of fossil fishes). He also uses fish faunas to determine temperatures, seasonality, and other ecological aspects of ancient environments. He is also involved with collaborations on projects focusing on Asian and African fishes, as well as projects describing Chinese trace fossils.

Current Research

Julien’s research aims to develop the use of the abundantly preserved microvertebrate fossils representing North American freshwater fishes between the Late Cretaceous and today.

  • Julien’s work mostly focuses on one kind of fish in particular, the Gonorynchiformes (milkfishes), represented by microvertebrate fossils in the Late Cretaceous Dinosaur Park Formation of southern Alberta.
  • These fossils are identified by comparing them to better-known relatives found as articulated specimens in the Eocene Green River Formation of Wyoming, from which individual bones can be mechanically extracted, allowing direct comparisons with the Canadian fossils.
  •  Both types of fossils can be compared to their closest living relatives, developing the use of microvertebrates to help time the appearance of certain morphological features within fish phylogenies.
