Aphelops is an extinct genus of rhinoceros endemic to North America during the Miocene through the Pliocene, living from 20.43—4.9 mya.[1]


A. fossiger skeletal restoration

Aphelops was named by Owen (1845) with species attributed to Cope 1873 and Cope 1874. It was assigned to Aceratheriinae by Prothero (1998); and to Rhinocerotidae by Owen (1845), Carroll (1988) and Hulbert and Whitmore (2006).[2][3]


Body mass[edit]

Five specimens were examined by M. Mendoza, C. M. Janis, and P. Palmqvist.[4] The results were:
