Altanius

Altanius is a genus of extinct primates found in the early Eocene of Mongolia. Though its phylogenetic relationship is questionable, many have placed it as either a primitive omomyid or as a member of the sister group to both adapoids and omomyids. The genus is represented by one species, Altanius orlovi, estimated to weigh about from relatively well-known and complete dental and facial characteristics.

==Morphology== Much of the fossilized remains of Altanius, as with any extinct vertebrate, are isolated teeth fragments. However, an abundance of specimens, collected between Dashzeveg and McKenna's initial discovery of the species in 1977 and the present, have yielded an almost complete dentition.
