Tetonius is a genus of anaptomorphine primate from Eocene Wyoming.¹

Description

The dental formula of Tetonius is 2,1,3,32,1,3-2,3 × 2 = 34-36. The premolars are bicuspid whilst the molars are tritubercular.¹ They had enlarged orbits and a shortened face.¹ Compared to other Wasatch Formation fauna, Tetonius had a rather large cranium.¹

Classification

Tetonius homunculus was originally ascribed to the genus Anaptomorphus,² though this is disputed now.³
