Dr. Zanno’s primary interest centers on the anatomy, phylogeny, and paleoecology of theropod dinosaurs—a group that includes the iconic megapredator T. rex as well as living birds. Although theropods are colloquially known as predatory dinosaurs, Dr. Zanno’s research has demonstrated extensive dietary diversity among bird-like theropods, including widespread plant eating. She is currently one of the world’s leading experts on a bizarre group of herbivorous theropods dubbed therizinosaurs, some species of which possessed scythe-shaped hand claws more than five feet in length.
Dr. Zanno’s field-based research tackles patterns of faunal turnover, extinction, and replacement in ancient terrestrial ecosystems, with a current focus on the southwestern USA. Here she works to identify the influence of geographic and climatic variables on faunal dynamics during two particularly turbulent periods in the Cretaceous of western North America—the late Early Cretaceous, a time of interchange and turn-over associated with the initial establishment of a transarctic land bridge, and the Campano-Maastrichtian, a time of remarkably high dinosaur diversity associated with tectonic evolution of the Western Interior Basin. Dr. Zanno also studies the ontogeny and life history of fossil vertebrates through her research on bone histology and trait expression. Her team continues to unearth one of the world’s largest samples of a single theropod dinosaur species from a mass death site known as the Crystal Geyser Quarry.
As Director of the Paleontology & Geology Research Laboratory, Dr. Zanno supervises the fossil preparation and citizen scientist volunteer programs.
