It was an anthracosaurian that lived in the Permian of North America.[1] The skeleton is that of a medium-sized, rather advanced reptile-like amphibian. In life it was about {{convert|1|m|ft|0}} long and may have looked vaguely like an iguana, though slower and with a more amphibian foot without claws. The dentition was somewhat blunt, indicating herbivory or possibly omnivory. PhylogenyTseajaia was described from a single, fairly complete specimen and was given its own family by Robert L. Carroll. It was originally thought to be a Seymouriamorph.[2] Additional finds allowing for a better taxonomic analysis indicate they belong in the Diadectomorpha, as the sister group to the large and more derived Diadectidae. Tseajaia itself being a fairly generalized form, gives a reasonable indication of the build and looks of the closest relatives of the amniotes.[3][4]References1. ^Time Traveler: In Search of Dinosaurs and Other Fossils from Montana to Mongolia by Michael Novacek 2. ^Moss, J.L.
