"A new hypertraguloid, Praetragulus electus, n. gen. and sp., is described from part of a skull and numerous mandibles, teeth, and limb bones from the Lower Oligocene of the Khoer-Dzan locality in eastern Mongolia. Besides species from Khoer-Dzan, Lophiomeryx gobiae from Ardyn-Obo is referred to Praetragulus. Praetragulus possessed a mixture of primitive and derived features that give evidence of its early offshoot from the Tragulina, connected with the Asian early adaptive radiation of that group. The peculiarities of the skull structure and the short premolar row, together with unfused magnum and trapezoid as well as unfused central metapodials, lead to the assumption of a close relationship between the Central Asian and the North American hypertragulids. The ancestor of the latter group may have invaded North America during the Eurasian-American faunal exchange in the late Middle Eocene, approximately 41 Ma"--P. [1].
