Uintanius

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]

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]
