Mounted skeleton

Leptomeryx was named by Leidy (1853). Its type is Leptomeryx evansi. It was assigned to Leptomerycinae by Matthew (1908); to Hypertragulidae by Cook (1934); and to Leptomerycidae by Leidy (1853) and then by Carroll (1988).[3]

Morphology

Leptomeryx was a small deer-like ruminant with somewhat slender body.
