A rhinoceros (/ r aɪ ˈ n ɒ s ər ə s / ry-NOSS-ə-rəss; from Ancient Greek ῥινόκερως (rhinókerōs) 'nose-horned'; from ῥίς (rhis) 'nose' and κέρας (kéras) 'horn'; [1] pl.: rhinoceros or rhinoceroses), commonly abbreviated to rhino, is a member of any of the five extant species (or numerous extinct species) of odd-toed ungulates (perissodactyls) in the family ...
Elasmotherium had similar running limbs to the white rhinoceros–which run at 30 km/h (19 mph) with a top speed of 40–45 km/h (25–28 mph). However, Elasmotherium had double the weight–about 5 t (5.5 short tons)–and consequently had a more restricted gait and mobility, likely achieving much slower speeds.
Both species are relatively small, and comparable in size to living Sumatran and Javan rhinoceros, with shoulder heights of 123–131 centimetres (4.04–4.30 ft), with Nesorhinus hayasaki being somewhat larger than N. philippinensis with an estimated body mass of approximately 1,018–1,670 kilograms (2,244–3,682 lb), in comparison to 998–1,185 kilograms (2,200–2,612 lb) estimated for N ...
Gaindatherium is believed to be the direct ancestor of the genus Rhinoceros. Among the features it shares with that genus are arched nasal bones that helped support its single horn and a forward-inclined back of skull. [2] Its skull is longer and narrower compared to Rhinoceros, with more primitive brachyodont teeth. [3]
Rhinoceros is a genus comprising one-horned rhinoceroses. This scientific name was proposed by Swedish taxonomist Carl Linnaeus in 1758. [ 1 ] The genus contains two species, the Indian rhinoceros ( Rhinoceros unicornis ) and the Javan rhinoceros ( Rhinoceros sondaicus ).
Ceratotherium mauritanicum is a species of fossil African rhinoceros found in the Late Pliocene to early Late Pleistocene of Morocco, Tunisia, and Algeria. [1] It is disputed as to whether remains from the Pliocene of East Africa belong to this species, and if so, whether C. mauritanicum is ancestral to the modern white rhinoceros (Ceratotherium simum).
Comparison of the head angle of Merck's rhinoceros (top) with that of Stephanorhinus hemitoechus and the woolly rhinoceros (middle and bottom, respectively). Merck's rhinoceros was a large rhinoceros, with a body mass in the range of 1,500–3,000 kilograms (3,300–6,600 lb), [1] with a 2016 study estimating an average body weight of around 1,800–1,900 kilograms (4,000–4,200 lb).

Stephanorhinus is an extinct genus of two-horned rhinoceros native to Eurasia and North Africa that lived during the Late Pliocene to Late Pleistocene.Species of Stephanorhinus were the predominant and often only species of rhinoceros in much of temperate Eurasia, especially Europe, for most of the Pleistocene.
