It contains three genera, Leptomeryx, Pronodens, and Pseudoparablastomeryx, which lived in North America during the Middle Eocene to Middle Miocene. Leptomeryx may also have occurred in Asia during the Early Oligocene. The subfamily was first named by Zittel in 1893.[1] Leptomerycinae were primitive and ancient ruminants, resembling small deer or musk deer, although they were more closely related to modern chevrotains. Its diet is stated to be that of a frugivore. TaxonomyLeptomerycinae was named by Zittel (1893). It was reranked as the subfamily Leptomerycinae by Matthew (1908). It was assigned to Hypertragulidae by Matthew (1908); and to Traguloidea by Carroll (1988).[2][3]MorphologyBody massOne specimen was examined by M. Mendoza, C. M. Janis, and P. Palmqvist for body mass:[4]
