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]
