Brachypotherium is an extinct genus of rhinocerotid that lived in Eurasia and Africa during the Miocene.[1] A first upper decidual molar referrable to Brachypotherium brachypus was found during gold mining in New Caledonia during the 19th century, being misidentified as a species of marsupial known as Zygomaturus.[2] However, rhinoceros were never native to New Caledonia, and the tooth was probably used as jewelry by a French convict deported there.[3]

Many species of Brachypotherium have been described. Some species have moved to other genera, such as B. aurelianense being transferred to Diaceratherium.[4] The genus was widespread during the Early and Middle Miocene, before heading into a decline. They went extinct in Eurasia by the beginning of the Late Miocene, with the African species B. lewisi surviving until the end of the epoch.[5]
