The scimitar oryx or scimitar-horned oryx (''Oryx dammah''), also known as the Sahara oryx, is a species of ''Oryx'' now extinct in the wild. It formerly inhabited all of North Africa. It has a long taxonomic history since its discovery in 1816 by Lorenz Oken, who named it the ''Oryx algazel''. This spiral-horned antelope stands a little more than at the shoulder. The males weigh and the females weigh . The coat is white with a red-brown chest and black markings on the forehead and down the length of the nose. The calves are born with a yellow coat, and the distinguishing marks are initially absent. The coats change to adult coloration at 3–12 months old. The scimitar oryx formed herds of mixed sexes of up to 70 members, usually guided by the bulls. They inhabited semideserts and deserts and were adapted to live in the extreme heat, with their efficient cooling mechanism and very low requirement of water. Scimitar oryx feed on foliage, grasses, succulent plants and plant parts during the night or early morning. Births peak between March and October. After a gestation of eight to nine months, one calf is born. Soon after, the female has a postpartum estrus. The scimitar oryx was once widespread in northern Africa. Its decline began as a result of climate change, and later it was hunted extensively for its horns. Today, it is bred in captivity in special reserves in Tunisia, Morocco and Senegal. The scimitar oryx was domesticated in Ancient Egypt and is believed to have been used as food and sacrificed as offerings to gods. Wealthy people in Ancient Rome also bred them. The use of their valuable hides began in the Middle Ages. The unicorn myth may have originated from sightings of a scimitar oryx with a broken horn. ==Taxonomy and naming== The scimitar oryx is a member of the genus ''Oryx'' and family Bovidae. The German naturalist Lorenz Oken first described it in 1816, naming it ''Oryx algazel''. The nomenclature has undergone various changes since then, with the introduction of names like ''Oryx tao'', ''O. leucoryx'', ''O. damma'', ''O. dammah'', ''O. bezoarticus'' and ''O. ensicornis''. In 1826, Philipp Jakob Cretzschmar used the name ''Oryx ammah'' for the species. A year later, the name ''Orys leucoryx'' came into use, but as this was a synonym of the Arabian oryx (then called ''Oryx beatrix''), it was abandoned, and ''Oryx algazel'' was accepted once more. Over a hundred years later, in 1951, Sir John Ellerman and Terence Morrison-Scott realized the invalidity of the name ''Oryx algazel''. Finally, in January 1956, the International Trust for Zoological Nomenclature accepted ''Oryx dammah'' as the scientific name. There have been no more changes since then, though many papers published after 1956 created confusion by using names like ''O. gazella tao''. Its scientific name, ''Oryx dammah'', is derived from: Ancient Greek (''orux''), meaning a gazelle or antelope (originally a pickaxe); Latin ''damma'' (fallow deer or antelope); and Arabic ''dammar'' (sheep).〔 The scimitar oryx is named for its horns,〔(【引用サイトリンク】url=http://www.arkive.org/scimitar-horned-oryx/oryx-dammah/#text=All )〕 which resemble scimitars.〔 Its common name in English is "scimitar-horned oryx", or simply "scimitar oryx".〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Scimitar oryx」の詳細全文を読む スポンサード リンク
