}}Duchesneodus is a large brontothere endemic to North America during the Eocene living from 46.2—38 mya, existing for approximately {{Mya|46.2-38|million years}}.[1] TaxonomyDuchesneodus 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]MorphologyTwo specimens were examined by M. Mendoza for body mass The first specimen was estimated to have a weight of {{Convert|215.7|kg|lb|abbr=on|sigfig=2}}. The second was estimated to have a weight of {{Convert|607|kg|lb|abbr=on|sigfig=2}}.[4] References1. ^PaleoBiology Database: Duchesneodus, basic info {{Brontotheriidae}}{{Taxonbar|from=Q5311279}}{{paleo-oddtoedungulate-stub}}2. ^S.
