Gelada
The gelada (''Theropithecus gelada'', , ), sometimes called the bleeding-heart monkey or the gelada baboon, is a species of Old World monkey found only in the Ethiopian Highlands, living at elevations of above sea level. It is the only living member of the genus '' Theropithecus'', a name derived from the Greek root words for "beast-ape" (θηρο-πίθηκος : thēro-píthēkos). Like its close relatives in genus ''Papio'', the baboons, it is largely terrestrial, spending much of its time foraging in grasslands, with grasses comprising up to 90% of its diet. It has buff to dark brown hair with a dark face and pale eyelids. Adult males have longer hair on their backs and a conspicuous bright red patch of skin shaped like an hourglass on their chests. Females also have a bare patch of skin but it is less pronounced, except during estrus, when it brightens and exhibits a "necklace" of fluid-filled blisters. Males average and females average in weight. The head-body length is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Theropithecus Brumpti
''Theropithecus brumpti'' was a large terrestrial monkey that lived in the mid to late Pliocene. It is an extinct species of papionin. This fossil primate is mostly known from skulls and mandibles found in Pliocene deposits excavated in the Shungura Formation, at the Omo River, Ethiopia. Both ''T. brumpti'' and its cousin, the extant gelada (''T. gelada''), were related to the baboon. Description Similar to most other such animals, ''T. brumpti'' was quadrupedal with highly dexterous, manipulative hands. Males grew very large, as evidenced by a specimen found at Lomekwi, Kenya, which was estimated to have weighed approximately 43.8 kilograms. (In comparison, the male gelada averages around 20 kilograms ). In addition, the male was most likely very colorful, with the female smaller and less colorful; the species displayed a high degree of sexual dimorphism. Like most papionins, the male possessed large canine teeth, primarily for display. Diet ''Theropithecus brumpti'' was ...

Old World Monkey
Old World monkeys are primates in the family Cercopithecidae (). Twenty-four genera and 138 species are recognized, making it the largest primate family. Old World monkey genera include baboons (genus '' Papio''), red colobus (genus '' Piliocolobus''), and macaques (genus '' Macaca''). Common names for other Old World monkeys include the talapoin, guenon, colobus, douc (douc langur, genus '' Pygathrix''), vervet, gelada, mangabey (a group of genera), langur, mandrill, drill, surili ('' Presbytis''), patas, and proboscis monkey. Phylogenetically, they are more closely related to apes than to New World monkeys, with the Old World monkeys and apes diverging from a common ancestor between 25 million and 30 million years ago. This clade, containing the Old World monkeys and the apes, diverged from a common ancestor with the New World monkeys around 45 to 55 million years ago. The individual species of Old World monkey are more closely related to each other than to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Ethiopian Highlands
The Ethiopian Highlands (also called the Abyssinian Highlands) is a rugged mass of mountains in Ethiopia in Northeast Africa. It forms the largest continuous area of its elevation in the continent, with little of its surface falling below , while the summits reach heights of up to . It is sometimes called the "Roof of Africa" due to its height and large area. It is the only country in the region with such a high elevated surface. This elevated surface is bisected diagonally by the Great East African Rift System which extends from Syria to Mozambique across the East African Lakes. Most of the Ethiopian Highlands are part of central and northern Ethiopia, and its northernmost portion reaches into Eritrean Highlands, Eritrea. History In the southern parts of the Ethiopian Highlands once was located the Kingdom of Kaffa, a medieval and Early modern period, early modern state, whence the coffee plant was exported to the Arabian Peninsula.

Theropithecus Oswaldi
''Theropithecus oswaldi'' is an extinct species of '' Theropithecus'' from the early to middle Pleistocene of Kenya, Ethiopia, Tanzania, South Africa, Spain, Morocco, and Algeria. The species went extinct in South Africa around 1 million years ago. Having existed alongside hominins like ''Homo erectus'', it is likely that conflict with early humans played a role in their extinction as a site has been found with many juveniles butchered. Description It is remarkable for its large size compared to other Old World monkeys. One source projects a specimen of ''Theropithecus oswaldi'' to have weighed .

Baboon
Baboons are primates comprising the biology, genus ''Papio'', one of the 23 genera of Old World monkeys, in the family Cercopithecidae. There are six species of baboon: the hamadryas baboon, the Guinea baboon, the olive baboon, the yellow baboon, the Kinda baboon and the chacma baboon. Each species is native to one of six areas of Africa and the hamadryas baboon is also native to part of the Arabian Peninsula.
