Early primate — Smilodectes gracilis
Geologic period: Middle Eocene — Bridgerian
Age: Eocene, Bridgerian.
Feeding: Diet reconstructed from dental anatomy.
Evidence: Skull, teeth and postcranial fossils document primate anatomy. Arboreal behavior is inferred from limb and joint morphology.
Why it matters: Smilodectes records the diversity of early primates living in warm Eocene North American ecosystems.
Plain Language Identity: An Eocene notharctid primate from North America.
What You Are Looking At: A composite reconstruction of Smilodectes gracilis.
