The plesiadapiform Plesiadapis cookei (right), compared to Notharctus tenebrosus (left), an early crown primate. Both come from Eocene Wyoming, though the former is slightly geologically …

Plesiadapiforms share some traits with living primates, including long fingers well designed for grasping, and other features of the skeleton that are related to arboreality (Bloch & Boyer, …

A new relatively complete skeleton of Plesiadapis cookei (illustration) enables analysis and comparison of Plesiadapis across a range of primates and related mammals.

Plesiadapis tricuspidens (Gervais 1877) Paleocene ~55 mya. The Plesiadapiformes were widely thought to be the earliest representatives of the primate order, but here they nest basal to …

Plesiadapis itself is polyphyletic, with P. cookei recovered as the sister taxon of Platychoerops. Our reconstructed phylogeny for the family is largely congruent with that of Gingerich (1976) …

Within the family, Pronothodectes is the likely ancestor of all other genera, while Plesiadapis may be directly ancestral to both Chiromyoides and Platychoerops. [3]
