Primates are relative newcomers on our planet. The earliest ones are found in the fossil record dating to 50-55 million years ago. These first prosimians thrived during the Eocene Epoch. There were no monkeys or apes for them to compete with yet.he first true primates evolved by 55 million years ago or a bit earlier, near the beginning of the Eocene Epoch. Their fossils have been found in North America, Europe, and Asia. They looked different from the primates today.
Plesiadapiformes is an extinct order of mammals which is either closely related to primates or a precursor of them. They first appear in the fossil record between 65 and 55 million years ago. It is thought that these were the first mammals to have developed finger nails in place of claws. Based on fossil evidence, the earliest known true primates were represented by the genus Teilhardina date to 55.8 million years old. This was a marmoset like primate that lived about 56-47 million years ago. Archicebus is a genus of primate also from around 55 million years ago.
