Our ScientistsJames Gardner, Ph.D.
Curator of Palaeoherpetology
James (Jim) Gardner, focuses on palaeoherpetology, the study of fossil amphibians (such as frogs and salamanders) and reptiles (such as snakes, lizards, and turtles). The primary goal of his research is to document and interpret the evolutionary history of Mesozoic and Tertiary members of the Lissamphibia, or so-called modern amphibians. His research focuses on the morphology, systematics, distribution (both geographically and temporally), and paleobiology of lissamphibian taxa, especially those with North American representatives. Because fossil and living lissamphibians have a near global distribution, his research includes regional and international components.

Over the next five years Jim’s work will include the following solo and collaborative research projects:
- re-evaluation of the supposed Late Cretaceous frog Nezpercius
- description of new Late Cretaceous frogs from Alberta
- revision and descriptions of new scapherpetontid and batrachosauroidid salamanders from the latest Cretaceous and Paleocene of the North American Western Interior
- survey of Late Cretaceous salamanders and albanerpetontids from Utah
- re-evaluation of a previously described Eocene salamander skeleton from Wyoming
- descriptions of new albanerpetontid fossils and taxa from the Paleocene of Alberta, the Late Cretaceous of Hungary and Romania, and the Pliocene of Romania
- description of a new amphibian assemblage from the Lower Cretaceous of southern England
Much of his fieldwork is in collaboration with Craig Scott, the Museum’s Curator of Fossil Mammals, and focuses on Upper Cretaceous and Palaeocene non-marine strata in southern Alberta and Saskatchewan. Their work involves relocating known fossil vertebrate localities and prospecting for new ones, interpreting the stratigraphic and depositional context of the localities, and collecting material from them. In future years they hope to expand the geographic scope of their fieldwork.
