Eotragus is an extinct genus of early bovid. Species belonging to the genus inhabited Europe, Africa, and Asia during the Miocene some 20-18 million years ago. It is related to the modern nilgai and four-horned antelope. It was small and probably lived in woodland environments.

The subfamily Caprinae, also sometimes referred to as the tribe Caprini, is part of the ruminant family Bovidae, and consists of mostly medium-sized bovids. A member of this subfamily is called a caprine.

<span class="mw-page-title-main">Bovidae</span> Family of mammals belonging to even-toed ungulates

The Bovidae comprise the biological family of cloven-hoofed, ruminant mammals that includes cattle, 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.

<span class="mw-page-title-main">Moschidae</span> Family of mammals belonging to even-toed ungulates

Moschidae is a family of pecoran even-toed ungulates, containing the musk deer (Moschus) and its extinct relatives. They are characterized by long 'saber teeth' instead of horns, antlers or ossicones, modest size and a lack of facial glands. While various Oligocene and Miocene pecorans were previously assigned to this family, recent studies find that most should be assigned to their own clades, although further research would need to confirm these traits. As a result, Micromeryx, Hispanomeryx, and Moschus are the only undisputed moschid members, making them known from at least 18 Ma. The group was abundant across Eurasia and North America during the Miocene, but afterwards declined to only the extant genus Moschus by the early Pleistocene.

<span class="mw-page-title-main">Four-horned antelope</span> Small antelope from Asia (Tetracerus quadricornis)

The four-horned antelope, also called chousingha, is a small bovid antelope native to central, South and Western India, along with a smaller population in Nepal. The sole member of the genus Tetracerus, the chousingha was first described in 1816 by French zoologist Henri Marie Ducrotay de Blainville. Three regional subspecies are currently recognised. The four-horned antelope has a yellowish-tan, sometimes reddish or goldenrod coat. It is slender with thin legs and a short tail. It stands nearly 55–64 cm (22–25 in) at the shoulder and weighs about 17–22 kg (37–49 lb). Its four horns are unique among antelopes and distinguish it from most other bovids. The longer pair of straight, spike-like horns is atop its head between the ears, while the other, shorter pair is on the forehead; its posterior horns are always longer than the anterior horns, which may even present as merely fur-covered "studs". While the posterior horns measure 8–12 cm (3.1–4.7 in), the anterior ones are usually 2–5 cm (0.79–1.97 in) long.

<i>Tragelaphus</i> Genus of mammals

Tragelaphus is a genus of medium-to-large-sized spiral-horned antelopes. It contains several species of bovines, all of which are relatively antelope-like. Species in this genus tend to be large in size and lightly built, and have long necks and considerable sexual dimorphism. Elands, including the common eland, are embedded within this genus, meaning that Taurotragus must be subsumed into Tragelaphus to avoid paraphyly. Alternatively, Taurotragus could be maintained as a separate genus, if the nyala and the lesser kudu are relocated to their own monospecific genera, respectively Nyala and Ammelaphus. Other generic synonyms include Strepsiceros and Boocercus. The name "Tragelaphus" comes from the mythical tragelaph.

<span class="mw-page-title-main">Antilopinae</span> Subfamily of mammals

The antilopines are even-toed ungulates belonging to the subfamily Antilopinae of the family Bovidae. The members of tribe Antilopini are often referred to as true antelopes, and include the gazelles, blackbucks, springboks, gerenuks, dibatags, and Central Asian gazelles. True antelopes occur in much of Africa and Asia, with the highest concentration of species occurring in East Africa in Sudan, Eritrea, Ethiopia, Somalia, Kenya, and Tanzania. The saiga inhabits Central and Western Asia, mostly in regions from the Tibetan Plateau and north of the Indian Subcontinent. The dwarf antelope species of tribe Neotragini live entirely in sub-Saharan Africa.

Antilope is a genus of twisted-horn bovid that contains a single living species, the blackbuck of South Asia. Two extinct species are also known.

The tribe Bovini or wild cattle are medium to massive bovines that are native to Eurasia, North America, and Africa. These include the enigmatic, antelope-like saola, the African and Asiatic buffalos, and a clade that consists of bison and the wild cattle of the genus Bos. Not only are they the largest members of the subfamily Bovinae, they are the largest species of their family Bovidae. The largest species is the gaur, weighing up to 1,500 kg (3,300 lb).

A gazelle is one of many antelope species in the genus Gazella. There are also seven species included in two further genera; Eudorcas and Nanger, which were formerly considered subgenera of Gazella. A third former subgenus, Procapra, includes three living species of Asian gazelles.

<span class="mw-page-title-main">Orleanian</span> Geologic time period

The Orleanian age is a period of geologic time, within the Miocene and used more specifically with European Land Mammal Ages. It precedes the Astaracian age and follows the Agenian age.

In biostratigraphy, MN 4 is one of the MN zones used to characterize the fossil mammal faunas of the Neogene of Europe. It is preceded by MN 3 and followed by MN 5; together, these three zones form the Orleanian age of the middle Miocene. This zone starts within magnetostratigraphic chron C5Dr, at 18 million years ago, and ends within chron C5Cr, at 17.0 million years ago, although some different correlations have been proposed.

Protragocerus is an extinct genus of antelope from the late Serravallian Age of the Miocene Epoch. Fossils of the genus have been found in France, India, and Saudi Arabia. It is classified under the tribe Boselaphini, subfamily Bovinae of the family Bovidae. The genus was first established by the French paleontologist Charles Depéret in 1887.

Bubalina is a subtribe of wild cattle that includes the various species of true buffalo. Species include the African buffalo, the anoas, and the wild water buffalo. Buffaloes can be found naturally in sub-Saharan Africa, South Asia and Southeast Asia, and domestic and feral populations have been introduced to Europe, the Americas, and Australia. In addition to the living species, bubalinans have an extensive fossil record where remains have been found in much of Afro-Eurasia.

<span class="mw-page-title-main">Domestication of the goat</span>

Goat evolution is the process by which domestic goats came to exist through evolution by natural selection. Wild goats — medium-sized mammals which are found in noticeably harsh environments, particularly forests and mountains, in the Middle East and Central Asia — were one of the first species domesticated by modern humans, with the date of domestication generally considered to be 8,000 BC. Goats are part of the family Bovidae, a broad and populous group which includes a variety of ruminants such as bison, cows and sheep. Bovids all share many traits, such as hooves and a herbivorous diet and all males, along with many females, have horns. Bovids began to diverge from deer and giraffids during the early Miocene epoch. The subfamily Caprinae, which includes goats, ibex and sheep, are considered to have diverged from the rest of Bovidae as early as the late Miocene, with the group reaching its greatest diversity in the ice ages.

<i>Tragoportax</i> Extinct genus of bovid

Tragoportax is an extinct genus of bovid ungulate. It lived during the upper Miocene, and its fossils have been found in Europe, Asia and Africa. Tragoportax is sometimes considered to have been a close relative of the extant nilgai, though it may have formed its own subfamily, along with Miotragocerus.
