Purgatorius
Purgatorius is an extinct genus of eutherian mammal from the early Paleocene epoch of western North America. It is typically believed to be the earliest example of a primate or protoprimate (a primatomorph precursor to the Plesiadapiformes), dating to nearly as old as 66 million years ago.
