Among other locations, well-preserved Acerorhinus skull specimens have been found at Kerassiá in North Eubonea, Greece. [3]

Taxonomy

Acerorhinus was named by Kretzoi (1942). Its type is Aceratherium zernowi. Originally, many species in this genus including A. zernowi were assigned to Chilotherium . It was assigned to Aceratheriini by Kaya and Heissig (2001); and to Aceratheriini by Antoine and Saraç (2005). [4]

Description

Acerorhinus had very short legs, more like Teleoceras than other Aceratherines. While most other Aceratherines were grazers, Acerorhinus had brachyodont teeth which indicate a preferences for browsing. [5]

Like other Aceratherines, it was hornless and had tusk-like incisors.

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

Elasmotherium is an extinct genus of large rhinoceros endemic to Eurasia during Late Miocene through to the Late Pleistocene, with the youngest reliable dates around 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 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 in the Mid to Late Pliocene of Northern Indochina and South China. 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, and its extinct relative Ceratotherium mauritanicum, of which Ceratotherium efficax is considered a synonym. Another species known as Ceratotherium praecox is now considered a member of the related genus Diceros. The placement of Ceratotherium neumayri from the Late Miocene of Europe and Western Asia within the genus has been questioned, with other authors assigning it to the separate genus Miodiceros. The species 'Ceratotherium’ advenientis is known from the Late Miocene of Italy.

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

Menoceras is a genus of extinct, small rhinocerotids endemic to most of southern North America and ranged as far south as Panama during the early Miocene epoch. It lived from around 30.7—19.7 Ma, existing for approximately 11 million years.

<i>Paraceratherium</i> Extinct genus of hornless rhinocerotoids from Eurasia

Paraceratherium is an extinct genus of hornless rhinocerotoids belonging to the family Paraceratheriidae. It is one of the largest terrestrial mammals that has ever existed and lived from the early to late Oligocene epoch. The first fossils were discovered in what is now Pakistan, and remains have been found across Eurasia between China and the Balkans. Paraceratherium means "near the hornless beast", in reference to Aceratherium, the genus in which the type species P. bugtiense was originally placed.

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

<i>Stephanorhinus</i> Extinct genus of rhinoceros

Stephanorhinus is an extinct genus of two-horned rhinoceros native to Eurasia and North Africa that lived during the Late Pliocene to Late Pleistocene.
