from Wikipedia resources: Cimolestes ("Bug Thief") is a genus of basal, non-placental eutherians. Fossils have been found in North America, where they first appeared during the Late Cretaceous; they died out at the start of the Paleocene.[1] They were once considered to be marsupials, then primitive placental mammals, but now are considered to be members of the order Cimolesta (which was named after the genus), outside of placental mammals proper
