Megalotragus
''Megalotragus'' was a genus of very large extinct African alcelaphines that occurred from the Pliocene to early Holocene.Thackeray, John Francis. (2015). Faunal Remains from Holocene Deposits, Excavation 1, Wonderwerk Cave, South Africa. African Archaeological Review. Its skull resembled that of modern hartebeests, but it differed in having a larger body size and wildebeest-like proportions. ''Megalotragus'' includes some of the largest bovid species in the tribe Alcelaphini, reaching a shoulder height of . The genus consists of three species of which ''Megalotragus priscus'' survived until the early Holocene 7.500 C14yBP. Description With a distance between the tips of its horns of around , ''Megalotragus'' is probably the largest alcelaphine bovid ever recorded, much bigger than the extanct wildebeest. The skull of ''Megalotragus'' is similar to that of the hartebeest: characterized by extreme elongation, and the fusion and posterior placement of the horn pedicels. However, ...

Alcelaphinae
The subfamily Alcelaphinae or tribe Alcelaphini of the family Bovidae contains wildebeest, hartebeest, bonteboks, and several similar species. Depending on the classification, there are 6–10 species placed in four genera, although ''Beatragus'' is sometimes considered a subgenus of ''Damaliscus'', and ''Sigmoceros'' for the Lichtenstein's hartebeest. Subfamily Alcelaphinae * Genus ''Beatragus'' ** Hirola, ''Beatragus hunteri'' * Genus ''Damaliscus'' ** Tsessebe, ''D. lunatus'' *** Korrigum, ''D. lunatus korrigum'' *** Topi, ''D. lunatus jimela'' *** Coastal topi, ''D. lunatus topi'' ** Bontebok, ''D. pygargus'' *** Bontebok (subspecies), ''D. p. pygargus'' *** Blesbok, ''D. p. phillipsi'' * Genus '' Alcelaphus'' ** Hartebeest, ''A. buselaphus'' *** Bubal hartebeest, †''A. b. buselaphus'' *** Coke's hartebeest, ''A. b. cokii'' *** Lelwel hartebeest, ''A. b. lelwel'' *** Western hartebeest, ''A. b. major'' *** Swayne's hartebeest, ''A. b. swaynei'' *** Tora hartebees ...

Rusingoryx
''Rusingoryx'' is a genus of extinct alcelaphine bovid artiodactyl closely related to the wildebeest. It contains only one species, ''R. atopocranion'', that lived on the plains of Kenya during the Pleistocene. It was originally named as a species of '' Megalotragus''. ''Rusingoryx'' is known for its strange pointed nose with a large nasal dome. This structure represents an instance of convergent evolution with the crests of hadrosaurid dinosaurs, which were used for display and vocalization. Studies have shown that the ''Rusingoryx'' is a specialized grazing animal, with a preference for arid grasslands. The first specimens, which were poorly preserved, were described in 1983, having been taken from a site called Bovid Hill on Rusinga Island Rusinga Island, with an elongated shape approximately 10 miles (16 km) from end to end and 3 miles (5 km) at its widest point, lies in the eastern part of Lake Victoria at the mouth of the Winam Gulf. Part of Kenya, it is lin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hartebeest
The hartebeest (; ''Alcelaphus buselaphus''), also known as kongoni or kaama, is an African antelope. It is the only member of the genus ''Alcelaphus''. Eight subspecies have been described, including two sometimes considered to be independent species. A large antelope, the hartebeest stands just over at the shoulder, and has a typical head-and-body length of . The weight ranges from . It has a particularly elongated forehead and oddly-shaped horns, a short neck, and pointed ears. Its legs, which often have black markings, are unusually long. The coat is generally short and shiny. Coat colour varies by the subspecies, from the sandy brown of the western hartebeest to the chocolate brown of the Swayne's hartebeest. Both sexes of all subspecies have horns, with those of females being more slender. Horns can reach lengths of . Apart from its long face, the large chest and the sharply sloping back differentiate the hartebeest from other antelopes. A conspicuous hump over the ...

Pleistocene Mammals Of Africa
The Pleistocene ( , often referred to as the ''Ice age'') is the geological epoch that lasted from about 2,580,000 to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations. Before a change was finally confirmed in 2009 by the International Union of Geological Sciences, the cutoff of the Pleistocene and the preceding Pliocene was regarded as being 1.806 million years Before Present (BP). Publications from earlier years may use either definition of the period. The end of the Pleistocene corresponds with the end of the last glacial period and also with the end of the Paleolithic age used in archaeology. The name is a combination of Ancient Greek grc, label=none, πλεῖστος, pleīstos, most and grc, label=none, καινός, kainós (latinized as ), 'new'. At the end of the preceding Pliocene, the previously isolated North and South American continents were joined by the Isthmus of Panama, causing a faunal interchange between the two ...

Holocene Extinctions
The Holocene ( ) is the current geological epoch. It began approximately 11,650 cal years Before Present (), after the Last Glacial Period, which concluded with the Holocene glacial retreat. The Holocene and the preceding Pleistocene together form the Quaternary period. The Holocene has been identified with the current warm period, known as MIS 1. It is considered by some to be an interglacial period within the Pleistocene Epoch, called the Flandrian interglacial.Oxford University Press – Why Geography Matters: More Than Ever (book) – "Holocene Humanity" section https://books.google.com/books?id=7P0_sWIcBNsC The Holocene corresponds with the rapid proliferation, growth and impacts of the human species worldwide, including all of its written history, technological revolutions, development of major civilizations, and overall significant transition towards urban living in the present.
