Welcome to Dr. Robert Reisz's vertebrate palaeontology research group at the University of Toronto's Mississauga campus. The lab has studied a diverse array of animals and biological processes, with a broad focus on Paleozoic and Mesozoic tetrapods, since Robert first began teaching at UTM in 1975, with our current focus centered on the unique early Permian tetrapod assemblage at Richards Spur, Oklahoma and on the evolutionary trends and features of the tetrapod dentition. Within these broad umbrellas, we seek to address broad questions related to evolution in deep time and extinct organisms, ranging from transitions in tooth implantation and replacement across major tetrapod clades to the radiation of terrestrial vertebrates in the early Permian. Robert has also ventured into other areas of research, including sauropodomorph dinosaur embryology and growth, and the preservation of organic remains within the bones of fossils. Details regarding our research areas, methods, study systems, and the members of our lab can be found in the tabs above.
