Duchesneodus is a large brontothere endemic to North America during the Eocene living from 46.2—38 mya, existing for approximately 8.2 million years.[1]

Taxonomy

Duchesneodus was named by Lucas and Schoch (1982).[2] It was assigned to Brontotheriidae by Lucas and Schoch (1982) and Carroll (1988); and to Brontotheriinae by Mader (1998).[3]

Morphology

Two specimens were examined by M. Mendoza for body mass The first specimen was estimated to have a weight of 215.7 kg (480 lb). The second was estimated to have a weight of 607 kg (1,300 lb).[4]
