Metacheiromys

Metacheiromys ("next to Cheiromys") is an extinct genus of placental mammals from extinct paraphyletic subfamily Metacheiromyinae within extinct paraphyletic family Metacheiromyidae in extinct order Palaeanodonta, that lived in North America (what is now Wyoming) from the early to middle Eocene.

==Etymology== The generic name means "next to Cheiromys" because the scientist who saw the bones mistakenly thought that the animal was a primate with hands like those of the lemurs from genus Daubentonia, whose synonym is Cheiromys.
