Plesiadapis tricuspidens

Plesiadapis is one of the oldest known primate-like mammal genera which existed about 58–55 million years ago in North America and Europe.[2][3] Plesiadapis means "near-Adapis", which is a reference to the adapiform primate of the Eocene period, Adapis. Plesiadapis tricuspidens, the type specimen, is named after the three cusps present on its upper incisors.
