Hypertragulus were primitive and ancient ruminants, resembling small deer or musk deer, although they were more closely related to modern chevrotains. Its diet is stated[by whom?] to be that of a frugivore.

Palaeoecology
editBecause its fossils are found predominantly in semiarid palaeosols, it is believed that Hypertragulus hesperius primarily inhabited semiarid biomes.[2]
