Brachypotherium is an extinct genus of rhinocerotid that lived in Eurasia and Africa during the Miocene. [1]

Many species of Brachypotherium have been described. Some species have moved to other genera, such as B. aurelianense being transferred to Diaceratherium . [2] 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. [3]

A first upper decidual molar referable 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. [4] However, rhinoceros were never native to New Caledonia, and the tooth likely originates from France and was probably used as jewelry by a French convict deported there. [5] [6]

Palaeoecology

Dental microwear and mesowear analysis suggests that B. brachypus was a mixed feeder. [7]

<i>Elasmotherium</i> Genus of extinct rhinoceroses

Elasmotherium is an extinct genus of large rhinoceros that lived in Eastern Europe, Central Asia and East Asia during Late Miocene through to the Late Pleistocene, with the youngest reliable dates of at least 39,000 years ago. It was the last surviving member of Elasmotheriinae, a distinctive group of rhinoceroses separate from the group that contains living rhinoceros (Rhinocerotinae).

<span class="mw-page-title-main">Rhinoceros</span> Family of mammals

A rhinoceros, commonly abbreviated to rhino, is a member of any of the five extant species of odd-toed ungulates (perissodactyls) in the family Rhinocerotidae; it can also refer to a member of any of the extinct species of the superfamily Rhinocerotoidea. Two of the extant species are native to Africa, and three to South and Southeast Asia.

<i>Teleoceras</i> Extinct genus of mammals

Teleoceras is an extinct genus of rhinocerotid. It lived in North America during the Miocene and Pliocene epochs during the Hemingfordian to the end of Hemphillian from around 17.5 to 4.9 million years ago. It grew up to lengths of 13 feet long.

<i>Diceros</i> Genus of Rhinocerotidae

Diceros is a genus of rhinoceros containing the extant black rhinoceros (Diceros bicornis) and several extinct species.

<i>Dicerorhinus</i> Genus of mammals

Dicerorhinus is a genus of the family Rhinocerotidae, consisting of a single extant species, the two-horned Sumatran rhinoceros, and several extinct species. The genus likely originated from the Late Miocene of central Myanmar. Many species previously placed in this genus probably belong elsewhere.

<i>Ceratotherium</i> Genus of mammals

Ceratotherium is a genus of the family Rhinocerotidae, consisting of a single extant species, the white rhinoceros, as well as several fossil species.

<i>Rhinoceros</i> (genus) Genus of mammals

Rhinoceros is a genus comprising one-horned rhinoceroses. This scientific name was proposed by Swedish taxonomist Carl Linnaeus in 1758. The genus contains two species, the Indian rhinoceros and the Javan rhinoceros. Although both members are threatened, the Javan rhinoceros is one of the most endangered large mammals in the world with only 60 individuals surviving in Java (Indonesia). The word 'rhinoceros' is of Greek origin meaning "nose-horn".
