In Depth
Smilodectes is another example of an early Eocene era primate, and one of the better known from North America. As a notharctine primate, Smilodectes was similar to the type genus of the group, Notharctus. Like its relatives, Smilodectes was a small and lightly built primate that spent most of its time up in the tree canopy, where it’s presumed to have been a leaf eater. This is also a reflection of Eocene ecosystems which had a much wider expanse of forests than what are seen today, especially within the United States.
