Prehistoric Artiodactyla genera

Andrewsarchus (), meaning "Andrews' ruler", is an extinct genus of artiodactyl that lived during the Middle Eocene in what is now China. The genus was first described by Henry Fairfield Osborn in 1924 with the type species A. mongoliensis based on a largely complete cranium. A second species, A. crassum, was described in 1977 based on teeth. A mandible, formerly described as Paratriisodon, does probably belong to Andrewsarchus as well. The genus has been historically placed in the families Mesonychidae or Arctocyonidae, or was considered to be a close relative of whales. It is now regarded as

Sivatherium ("Shiva's beast", from Shiva and therium, Latinized form of Ancient Greek θηρίον - thēríon) is an extinct genus of giraffid that ranged throughout Africa and Eurasia. The species Sivatherium giganteum is, by weight, one of the largest giraffids known, and also one of the largest ruminants of all time. Sivatherium originated during the Late Miocene (around 7 million years ago) in Africa and survived through to the late Early Pleistocene (Calabrian) until around 1 million years ago.

Entelodon (meaning 'complete teeth', from Ancient Greek entelēs 'complete' and odōn 'tooth', referring to its "complete" eutherian dentition), formerly called Elotherium, is an extinct genus of entelodont artiodactyl found in Eurasia. Fossils of species of Entelodon are found in Paleogene strata ranging in age from the Houldjinian (37.2–33.9 mya) until the Rupelian epoch of the early Oligocene (33.9–28.4 mya).

Camelops is an extinct genus of camel that lived in North and Central America from the middle Pliocene (from around 4-3.2 million years ago) to the end of the Pleistocene (around 13-12,000 years ago). It is more closely related to living camels than to lamines (llamas, alpacas, vicuñas, and guanacos), making it a true camel of the Camelini tribe. Its name is derived from the Ancient Greek (, "camel") and (, "face"), i.e. "camel-face". Camelops lived across Western North America, ranging from the Pacific Coast to the Great Plains, southwards to Honduras and northwards to Alaska. Camelops became

Megaloceros (from Greek: + , literally "Great Horn"; see also Lister (1987)) is an extinct genus of deer whose members lived throughout Eurasia from the Pleistocene to the early Holocene. The type and only undisputed member of the genus, Megaloceros giganteus, vernacularly known as the "Irish elk" or "giant deer", is also the best known. Fallow deer are thought to be their closest living relatives. Megaloceros has been suggested to be closely related to other genera of "giant deer", like the East Asian genus Sinomegaceros and the largely European Praemegaceros, the species of both genera havin

Hexaprotodon is an extinct genus of hippopotamid known from Asia and possibly Africa and Europe. The genus name Hexaprotodon comes from Ancient Greek ἑξα- (hexa-), meaning "six", πρῶτος (prôtos), meaning "first", and ὀδούς (odoús), meaning "tooth", therefore, "six front-teeth" as some of the fossil forms have three pairs of incisors. The pygmy hippopotamus was historically placed in the genus, but today is generally placed in its own genus. The core Asian members of the genus ranged from the Indian subcontinent to Southeast Asia, and are thought to have had an aquatic ecology similar to that o

Archaeotherium (, meaning "ancient beast") is an extinct genus of entelodont artiodactyl endemic to North America during the Eocene and Oligocene epochs (35–28 mya). Archaeotherium fossils are most common in the White River Formation of the Great Plains, but they have also been found in the John Day Basin of Oregon and the Trans-Pecos area of Texas. Archaeotherium's fossils come from North America, between the Priabonian and Rupelian stages of the Eocene and Oligocene (35–28 million years ago). Up to fifteen species of Archaeotherium have been identified, which are divided into three subgenera

Samotherium ("beast of Samos") is an extinct genus belonging to the family Giraffidae from the Miocene and Pliocene of Eurasia and Africa. Samotherium had two ossicones on its head and possessed long legs. The ossicones usually pointed upward, and were curved backwards, with males having larger, more curved ossicones, though in the Chinese species, S. sinense, the straight ossicones point laterally, not upwards. The genus is closely related to Shansitherium. Fossil evidence suggests that Samotherium had a rounded muzzle, which would suggest a grazing lifestyle and a habitat composed of grassla

Anthracotherium (from Ancient Greek ἄνθραξ (ánthrax), meaning "coal", and θηρίον (theríon), meaning "beast") is an extinct genus of anthracotheriid artiodactyls characterized by having 44 teeth, with five semi-crescentic cusps on the crowns of the upper molars. The genus ranged from the middle Eocene period until the early Miocene, having a distribution throughout Eurasia probably even reaching South East Asia (Kalimantan and West Timor). Material subjectively assigned to Anthracotherium from Pakistan suggests the last species died out soon after the start of the Miocene.

Eucladoceros (Greek for "well-branched antler") is an extinct genus of large deer whose fossils have been discovered across Eurasia, from Europe to China, spanning from the Early Pliocene to the end of the Early Pleistocene. The various species of the genus are noted for their unusual comb-like or branching antlers, though antler shape varied considerably between different species.

Aepycamelus is an extinct genus of camelids that lived during the Miocene 20.6–4.9 million years ago, existing for about . Its name is derived from the Homeric Greek , "high and steep" and κάμηλος – "camel"; thus, "high camel"; alticamelus in Latin.

Palaeotragus ("ancient goat") is a genus of very large, primitive, okapi-like giraffids from the Miocene to Early Pleistocene of Africa and Eurasia.

Giraffokeryx is an extinct genus of medium-sized giraffids known from the Miocene of the Indian subcontinent and Eurasia. It is distinguished from other giraffids by the four ossicones on its head; one pair in front of the eyes on the anterior aspect of the frontal bone and the other behind the eyes in the frontoparietal region overhanging the temporal fossae. It has a brachydont dentition like in other giraffids and its legs and feet are of medium length. Giraffokeryx is considered monotypic by most authors, in the form of G. punjabiensis, but other species have been assigned to the genus: G

Pelorovis is an extinct genus of African wild cattle which existed during the Pleistocene epoch. Originally believed to be a giant member of Caprinae, related to modern sheep, it is now known to be a relative of cattle and buffalos. The best known and type species is Pelorovis oldowayensis, from the Early Pleistocene of Olduvai Gorge, Tanzania, though two others, P. turkanensis and P. howelli, are currently recognised. A fourth, P. praeafricanus, may exist, or it may represent the same species as P. oldowayensis. "Pelorovis" antiquus, from the Late Pleistocene-Holocene, and "P." kaisensis, hav

Fossils of Prolibytherium were found in the Marada Formation of Libya, Vihowa Formation of Pakistan, and the Moghara Formation of Egypt.

Cervalces is an extinct deer genus that lived during the Pliocene and Pleistocene epochs. Cervalces gallicus is either classified as a species of the related Libralces, or an ancestral species to other members of Cervalces. It lived in Europe from the Pliocene to the Pleistocene. Cervalces scotti, the stag-moose, lived in Pleistocene North America. Cervalces latifrons, the broad-fronted moose, and Cervalces carnutorum were found in Pleistocene Europe and Asia. The genus has been suggested to be paraphyletic and ancestral with respect to Alces, the genus which contains the modern moose, and as

Discoveries of incomplete skeletons of A. commune in 1807 led Cuvier to thoroughly describe unusual features for which there are no modern analogues. His drawn skeletal

Kubanochoerus is an extinct genus of large, long-legged suid artiodactyl mammal from the Miocene of Eurasia and Africa.

Elomeryx is an extinct genus of artiodactyl ungulate, and is among the earliest known anthracotheres. The genus was extremely widespread, first being found in Asia in the middle Eocene, in Europe during the latest Eocene, and having spread to North America by the early Oligocene. The closest living relatives of the Elomeryx are said suids, and hippopotamids (hippopotami and cetaceans). thumb|left|Restoration of E. armatus Elomeryx was about in body length, and had a long, vaguely horse-like head. It had small tusks which it used to uproot plants, and spoon-shaped incisors ideal for pulling an

Kolpochoerus is an extinct genus of the pig family Suidae related to the modern-day genera Hylochoerus, Phacochoerus, and Potamochoerus. It is believed that most of them inhabited African forests, as opposed to the bushpig and red river hog that inhabit open brush and savannas. There are currently eleven recognized species.

Merycopotamus is an extinct genus of Asian anthracothere that appeared during the Middle Miocene, and died out in the Late Pliocene. At the height of the genus' influence, species ranged throughout South Asia and South East Asia (Indonesia, Myanmar, and Thailand). With the extinction of the last species, M. dissimilis, the lineage of anthracotheres came to an end. Merycopotamus was closely related to the anthracothere genus Libycosaurus, which, unlike the former, never left Africa. In fact, some African fossils originally placed in Merycopotamus, but are now referred to Libycosaurus.
