Not to be confused with Uinta Formation and Uintatherium.

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 , ^[5] though the nature of Altanius as an incartae sedis may bring that classification into question. ^[6] Another genus of Uintanin, Jemezius, has been synonymized with Uintanius. ^[2]
