Plesiadapis is one of the oldest known primate-like mammal species which existed about 58-55 mya in North America and Europe. It looked a little like a squirrel. Plesiadapis still had claws and its eyes were located on each side of the head, making them faster on the ground than on the top of the trees, but they begin to spend long times on lower branches of trees, feeding on fruits and leaves.
