Nanotragulus is an extinct genus belonging to the family Hypertragulidae, within the order Artiodactyla, endemic to North America, Europe, and Asia during the Eocene through Miocene, living 46.2–13.6 Ma, existing for approximately 32.6 million years.[1]
Nanotragulus was a primitive and ancient ruminant, resembling small deer or musk deer, although more closely related to the modern chevrotain. Its diet is stated[by whom?] to be that of a frugivore.
Taxonomy
Nanotragulus was named by Lull (1922). It was assigned to Cervidae by Cook (1934); and to Hypertragulidae by Lull (1922), Matthew (1926) and Carroll (1988).[2][3][4]
