Herpetotherium is an extinct genus of metatherian mammal.
Herpetotherium fugax
Restoration
Fossils have been found in California, Oregon, Texas, Florida, Montana, Wyoming, Colorado, North and South Dakota, Nebraska, and Saskatchewan.[1] The oldest species, H. knighti, is dated to around 50.3 mya,[2] and the most recent, an unnamed species, may be as recent as 15.97 mya.[1] A morphological analysis of marsupials and basal metatherians conducted in 2007 found Herpetotherium to be the sister group to extant marsupials.[3]
