Jeffrey W. Martz studies the Upper Triassic stratigraphy and vertebrate paleontology of the western United States. Dr. Martz is interested in understanding the environmental and evolutionary changes that allowed dinosaurs to become the dominant land animals early in the Mesozoic Era over 200 million years ago. In addition to studying the systematics of early dinosauromorphs and pseudosuchian archosaurs, he is currently developing detailed lithostratigraphic and biostratigraphic models for the Upper Triassic Chinle Formation in western North America that will be used to track the relationship between paleoenvironmental (especially paleoclimatic) change and paleoecology. Much of his work has focused on increasing the methodological rigor of Late Triassic paleontological and stratigraphic research.
