Plesiadapiformes is an extinct order of mammals. It is either closely related to the primates or a pre-cursor to them. Many are too derived to be ancestral to primates. Earliest ones have teeth that are strongly indicative that they share a common ancestor with primates. Purgatorius is the earliest fossil that could have given rise to both primates and plesiadapiformes.

Plesiadapiforme first showed up in the Cretaceous period, though many were extinct by the beginning of the Eocene.
