Within mammals, only primates have binocular vision, grasping hands, and flat nails–instead of claws. Purgatorius might have had all three earning it the earliest known proto-primate label. It lived in Eastern Montana about 66 million years ago during the very last years of the Cretaceous period. It lived through the K-T extinction event and the extinction of dinosaurs.
