What is "tsoabichi"

Tsoabichi is an extinct genus of caiman crocodylian. Fossils are known from the Green River Formation in Wyoming, and date back to the Wasatchian stage of the Eocene. The genus was named and described in 2010 by paleontologist Christopher A. Brochu, with the type species being Tsoabichi greenriverensis. According to the current understanding of caiman evolutionary relationships, Tsoabichi is a basal member of Caimaninae and likely evolved after caimans dispersed into North America from northern and central South America, their main center of diversity in the Paleozoic.
