Title

Plesiadapis tricuspidens

Subject

Plesiadapis was a lemur-like animal that existed around 55.8 to 48.6 MYA, and fossils of this species has been found in multiple locations all over the world. It had claws instead of nails, which demonstrates how ancient and primitive this mammal was. Plesiadapis plays a crucial role in the realm of mammals: it is a possible ancestor to all modern primates. Without Plesiadapis, the family tree of primates may not have evolved, expanded, and grown.
