Plesiadapidae


Plesiadapidae is a family of plesiadapiform mammals related to primates known from the Paleocene and Eocene of North America, Europe, and Asia. Plesiadapids were abundant in the late Paleocene, and their fossils are often used to establish the ages of fossil faunas.

Classification

McKenna and Bell recognized two subfamilies and one unassigned genus within Plesiadapidae. More recently Saxonella and Pandemonium have been excluded from the family, leaving only a redundant Plesiadapinae. Within the family, Pronothodectes is the likely ancestor of all other genera, while Plesiadapis may be directly ancestral to both Chiromyoides and Platychoerops.
