Heptodon is an extinct genus of tapir-type herbivore of the family Helaletidae endemic to North America during the Early Eocene. It lived from 50.3—48.6 mya, existing for approximately 1.7 million years.[1]
Heptodon was about 1 metre (3.3 ft) in length, and closely resembled modern tapirs. The shape of the skull suggests that it probably lacked the characteristic tapir trunk. Instead it probably had a slightly elongated, fleshy upper lip, like its relative Helaletes.[2]
