Elasmotherium is an extinct genus of large rhinoceros endemic to Eastern Europe and Central Asia with isolated finds from East Asia 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).
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.
Diceros is a genus of rhinoceros containing the extant black rhinoceros (Diceros bicornis) and several extinct species.
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.
Iranotherium is an extinct genus of large elasmotheriine rhinocerotids, comparable in size to a modern white rhino. It is known from the Late Miocene (Tortonian) of Maragha, Iran and the middle part of the Liushu formation of northwestern China. It was a precursor to the related Sinotherium and may have been ultimately outcompeted by its descendant. This species is most well known for showing unique sexual dimorphism among rhinos.
Subhyracodon is an extinct genus of hornless rhinocerotids. With a length of 2.4 m and an estimated weight of 381 kg (840 lb) in S. mitis, it was a tapir-sized herbivore on the plains of early Oligocene South Dakota 33 million years ago. It coexisted with other perissodactyls such as horses, brontotheres, and chalicotheres. Subhyracodon had no horns, relying more on its speed to escape from predators, but a species found at Wind Cave National Park had a pair of bony nasal ridges. The genus Caenopus and species originally referred to as Aceratherium were synonymized into Subhyracodon. It has been suggested to be one of the oldest known members of the subfamily Elasmotheriinae by some studies, though other studies place it firmly outside the Rhinocerotinae-Elasmotheriinae split.
Chilotherium is an extinct genus of rhinocerotids endemic to Eurasia during the Miocene through Pliocene living for 13.7—3.4 mya, existing for approximately 10.3 million years.
Euthecodon is an extinct genus of long-snouted crocodile. It was common throughout much of Africa during the Neogene, with fossils being especially common in Kenya, Ethiopia, and Libya. Although superficially resembling that of gharials, the long snout was a trait developed independently from that of other crocodilians and suggests a diet of primarily fish. Euthecodon coexisted with a wide range of other crocodiles in the areas it inhabited before eventually going extinct during the Pleistocene.
Ceratotherium neumayri is a fossil species of rhinoceros from the Late Miocene (Vallesian-Turolian) of the Balkans and Western Asia, with remains known from Greece, Bulgaria, Iran, and Anatolia in Turkey.
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. The last two species of Stephanorhinus – Merck's rhinoceros and the narrow-nosed rhinoceros – went extinct during the last glacial period.
Victoriaceros is an extinct genus of elasmotheriine rhinoceros known from the Miocene of Maboko Island, Kenya.
Rusingaceros or Dicerorhinus leakeyi is an extinct genus of rhinocerotid known from the Miocene of Rusinga Island, Kenya.
Deng Tao is a Chinese palaeontologist at the Institute of Vertebrate Paleontology and Paleoanthropology (IVPP), Chinese Academy of Sciences, who has made important fossil discoveries on Cenozoic mammals. He is a professor of vertebrate palaeontology, deputy director of the Academic Committee, and deputy director of Key Laboratory of Evolutionary Systematics of Vertebrates at IVPP.
Tsaidamotherium is an extinct genus of Late Miocene ovibovinid caprine from the Tibetan Plateau of Northwestern China. Both known species are extremely unusual in that the horns are of unequal sizes: the left horn core is several times smaller than the right horn core. Although it is originally considered that it belongs to the tribe Ovibovini, close to the muskox, Ovibos moschatus, a study in 2022 posits Tsaidamotherium as a giraffoidean genus in the family Prolibytheriidae together with Prolibytherium and Discokeryx.
Forstercooperia is an extinct genus of forstercooperiine paraceratheriid rhinocerotoids from the Middle Eocene of Asia.
Pappaceras is an extinct genus of rhinocerotoids from the Early Eocene of Asia belonging to Paraceratheriidae.
The Liushu Formation is a geological formation in Gansu province, China that spans up to 100 m thick and is widely distributed within the Linxia Basin, with a paleomagnetic age between 11 and 6.4 mya.
Dihoplus is an extinct genus of rhinoceros that lived in Eurasia from the Late Miocene to Pliocene.
Eoazara xerrii is a species of extinct elasmotheriine rhinoceros from the upper Miocene of Morocco, the first definitive representative of the subfamily in North Africa. It is known from a well preserved skull and postcranial material, preserving the most complete late Miocene rhino skull found in Africa.
Pliorhinus is an extinct genus of rhinoceros known from the Late Miocene and Pliocene of Eurasia. The type species, Pliorhinus megarhinus, was previously assigned to Dihoplus.
