Kubanochoerus is an extinct genus of large, long-legged suid artiodactyl mammal from the Miocene of Eurasia and Africa.
The genera Libycochoerus and Megalochoerus were once assigned to Kubanochoerus but are now considered distinct based on dental and minor cranial details. [2]
The putative paraceratheriid genus Caucasotherium, described from the Caucasus on the basis of a bone fragment with four incisors, is actually a synonym of the Middle Miocene Kubanochoerus gigas. [3]
The largest species, the aptly named K. gigas, grew to be around 1 metre (3.3 ft) at the shoulder, and probably weighed up to 500 kilograms (1,100 lb) in life. [4] The heads of these pigs were unmistakable, with small eyebrow horns, and a large horn emanating from the forehead of the males. It is speculated that the males used their forehead horns for jousting with each other.
The Bovidae comprise the biological family of cloven-hoofed, ruminant mammals that includes cattle, yaks, bison, buffalo, antelopes, sheep and goats. A member of this family is called a bovid. With 143 extant species and 300 known extinct species, the family Bovidae consists of 11 major subfamilies and thirteen major tribes. The family evolved 20 million years ago, in the early Miocene.
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).
Platybelodon is an extinct genus of large herbivorous proboscidean mammals related to modern-day elephants, placed in the "shovel tusker" family Amebelodontidae. Species lived during the middle Miocene Epoch in Africa, Asia and the Caucasus.
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.
Ostriches are large flightless birds. Two living species are recognised, the common ostrich, native to large areas of sub-Saharan Africa, and the Somali ostrich, native to the Horn of Africa.
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.
Amphicyon is an extinct genus of large carnivorans belonging to the family Amphicyonidae, subfamily Amphicyoninae, from the Miocene epoch. Members of this family received their vernacular name for possessing bear-like and dog-like features. They ranged over North America, Europe, Asia, and Africa.
Gomphotherium is an extinct genus of gomphothere proboscidean from the Neogene of Eurasia, Africa and North America. It is the most diverse genus of gompothere, with over a dozen valid species. The genus is probably paraphyletic.
Prolibytherium is an extinct genus of prolibytheriid artiodactyl ungulate native to Middle Miocene North Africa and Pakistan, from around 16.9 to 15.97 million years ago. Fossils of Prolibytherium were found in the Marada Formation of Libya, Vihowa Formation of Pakistan, and the Moghara Formation of Egypt.
Sinotherium is an extinct genus of single-horned elasmotheriine rhinocerotids that lived from the late Miocene to Early Pliocene. It was ancestral to Elasmotherium, demonstrating a very important evolutionary transition from nasal-horned elasmotheriines to frontal-horned elasmotheriines. Its fossils have been found in the Karabulak Formation of Kazakhstan, lower jaw and teeth have been found in Mongolia, and a partial skull is known from the upper part of the Liushu Formation of western China. Sinotherium diverged from the ancestral genus, Iranotherium, first found in Iran, during the early Pliocene. Some experts prefer to lump Sinotherium, and Iranotherium into Elasmotherium.
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.
The tribe Tragelaphini, or the spiral-horned antelopes, are bovines that are endemic to sub-Saharan Africa. These include the bushbucks, kudus, and the elands. The scientific name is in reference to the mythical creature the tragelaph, a Chimera with the body of a stag and the head of a goat. They are medium-to-large, tall, long-legged antelopes characterized by their iconic twisted horns and striking pelage coloration patterns.
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.
Gobicyon is an extinct genus of large-sized carnivoran mammals, belonging to the Amphicyonidae, that was discovered in China, Mongolia, and Serbia, and lived during the Middle Miocene epoch. Despite only being known from rather fragmentary remains, recent discoveries showcase that it was an aberrant member of the subfamily Haplocyoninae, with adaptions towards bone-crushing similar to those of a hyaena.
Libycochoerus is an extinct genus of large and long-legged animals in the pig family from the Miocene of Africa.
Megalochoerus is an extinct genus of large and long-legged pig-like animals from the Miocene of Africa.
Amphimachairodus is an extinct genus of large machairodonts. It is also a member of the tribe Homotherini within Machairodontinae and is most closely related to such species as Xenosmilus, Homotherium itself, and Nimravides. It inhabited Eurasia, Northern Africa and North America during the late Miocene epoch.
Paratrigodon is an extinct genus notoungulate belonging to the subfamily Toxodontinae, containing one species, P. euguii. Like its close relative Trigodon, it is known for the presence of a horn-like protuberance on its forehead. Fossils of Paratrigodon are known from the Arroyo Chasicó Formation dating from the Chasicoan period, and teeth from the Laventan-aged Quebrada Honda Fauna of Bolivia were also associated with the genus, although considered too different from the type species to be assigned to it.
Discokeryx is an extinct genus of even-toed ungulates, possibly related to the modern giraffe and okapi. D. xiezhi was alive during the Early Miocene period 17–16.9 million years ago. Fossilized remains of this animal were discovered in the Halamagai Formation located in northwest China. This species is known for their thick skulls and stumpy necks used for fighting other male D. xiezhi.
