Uintanius is a genus of omomyine primate known from Eocene North America. [1]

Description

Uintanius has been compared to Omomys in dentition, with both genera bearing low crowned molars (a trait nearly exclusive to them among the omomyines). [2]

Classification

The positioning of Uintanius on the omomyid family tree has been contested, with some phylogenies placing the genus with the anaptomorphines, [3] while others return it as a basal omomyine. [4] [3] The unique morphology of Uintanius has caused it to be grouped in the tribe Uintaniini alongside Altanius , [2] though the nature of Altanius as an incartae sedis may bring that classification into question. [5] Another genus of uintaniin, Jemezius, has been synonymized with Uintanius. [2]
