propliopithecids: This is a somewhat diverse group of fossil primates. Although they were larger in body size, they still showed signs of arboreal quadrupedalism. They had a 2.1.2.3/2.1.2.3 dental formula and ate mainly fruit. oligopithecids: These primates share many primitive features with the Eocene strepsirhines.
