Tatmanius is a genus of omomyid primate from Eocene North America.[1]

Description

[edit]

Tatmanius was rather derived, having similar dentition to Trogolemur. Tatmanius lacks a second premolar, much like the related Pseudotetonius.[2] The third premolar was also small compared to other anaptomorphines, and the fourth bore a bilobed root.[3] It is speculated that Tatmanius descended from Pseudotetonius, as they share remarkable similarity in dentition.[2]
