Praeovibos priscus, also known as the giant muskox, is an extinct mammal species of the family Bovidae.
 This species used to be regarded as the ancestor to the modern muskox ("Ovibos moschatus") but new findings of these two species of the same age has questioned this believe.
The gymnure, also called a hairy hedgehog or moonrat, is a type of mammal belonging to the subfamily Galericinae, in the family Erinaceidae and the order Eulipotyphla.
 Gymnures resemble rats but are not closely related as they are not rodents: they are instead closely related to hedgehogs.
 They are thought to have appeared in Eastern Asia before their closest relatives, and changed little from the original ancestor, which is thought to have been also the ancestor of the shrews.
Tsaidamotherium is an extinct genus of Late Miocene ovibovinid caprid 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.
 The closest living relative of "Tsaidamotherium" is probably the Muskox, "Ovibos moschatus".
The fossa ( or ; Malagasy ] ; "Cryptoprocta ferox") is a cat-like, carnivorous mammal endemic to Madagascar.
 It is a member of the Eupleridae, a family of carnivorans closely related to the mongoose family (Herpestidae).
 Its classification has been controversial because its physical traits resemble those of cats, yet other traits suggest a close relationship with viverrids (most civets and their relatives).
 Its classification, along with that of the other Malagasy carnivores, influenced hypotheses about how many times mammalian carnivores have colonized Madagascar.
 With genetic studies demonstrating that the fossa and all other Malagasy carnivores are most closely related to each other (forming a clade, recognized as the family Eupleridae), carnivorans are now thought to have colonized the island once around 18 to 20 million years ago.
Several mammals are known from the Mesozoic of Madagascar.
 The Bathonian (middle Jurassic) "Ambondro", known from a piece of jaw with three teeth, is the earliest known mammal with molars showing the modern, tribosphenic pattern that is characteristic of marsupial and placental mammals.
 Interpretations of its affinities have differed; one proposal places it in a group known as Australosphenida with other Mesozoic tribosphenic mammals from the southern continents (Gondwana) as well as the monotremes, while others favor closer affinities with northern (Laurasian) tribosphenic mammals or specifically with placentals.
 At least five species are known from the Maastrichtian (late Cretaceous), including a yet undescribed species known from a nearly complete skeleton that may represent a completely new group of mammals.
 The gondwanathere "Lavanify", known from two teeth, is most closely related to other gondwanatheres found in India and Argentina.
 Two other teeth may represent another gondwanathere or a different kind of mammal.
 One molar fragment is one of the few known remains of a multituberculate mammal from Gondwana and another (UA 8699) has been interpreted as either a marsupial or a placental.
The red hartebeest ("Alcelaphus buselaphus caama" or "A. caama") is a species of even-toed ungulate in the family Bovidae found in Southern Africa.
 More than 130,000 individuals live in the wild.
 The red hartebeest is closely related to the tsessebe and the topi.
The common tsessebe or sassaby ("Damaliscus lunatus lunatus") is one of five subspecies of African antelope "Damaliscus lunatus" of the genus "Damaliscus" and subfamily Alcelaphinae in the family Bovidae.
 It is most closely related to the topi, korrigum, coastal topi and tiang (all subspecies of "Damaliscus lunatus"), and the bangweulu tsessebe and bontebok in the same genus.
 Tsessebe are found primarily in Angola, Zambia, Namibia, Botswana, Zimbabwe, Swaziland, and South Africa.
 Tsessebe can run at a maximum of 80 km/h.
The black wildebeest or white-tailed gnu ("Connochaetes gnou") is one of the two closely related wildebeest species.
 It is a member of the genus "Connochaetes" and family Bovidae.
 It was first described in 1780 by Eberhard August Wilhelm von Zimmermann.
 The black wildebeest is typically between 170 - in head-and-body length, and the average weight is 110 - .
 Males stand up to approximately 111 - at the shoulder, while the height of the females is 106 - .
 The black wildebeest is characterised by its white, long, horse-like tail.
 It also has a dark brown to black coat and long, dark-coloured hair between its forelegs and under its belly.
The muskox ("Ovibos moschatus"), also spelled musk ox and musk-ox (in Inuktitut: ᐅᒥᖕᒪᒃ, "umingmak" ), is an Arctic mammal of the family Bovidae, noted for its thick coat and for the strong odor emitted during the seasonal rut by males, from which its name derives.
 This musky odor is used to attract females during mating season.
 Its Inuktitut name "umingmak" translates to "the bearded one".
 Muskoxen primarily live in the Canadian Arctic and Greenland, with small introduced populations in Alaska, the Scandinavian Peninsula, and Siberia.
The tamaraw or Mindoro dwarf buffalo ("Bubalus mindorensis") is a small hoofed mammal belonging to the family Bovidae.
 It is endemic to the island of Mindoro in the Philippines, and is the only endemic Philippine bovine.
 It is believed, however, to have once also thrived on the larger island of Luzon.
 The tamaraw was originally found all over Mindoro, from sea level up to the mountains (2000 meters above sea level), but because of human habitation, hunting, and logging, it is now restricted to only a few remote grassy plains and is now an endangered species.
