Theropithecus Gelada
The gelada (''Theropithecus gelada'', am, ጭላዳ, translit=č̣əlada), 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". 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 with a tail o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Debre Libanos
Debre Libanos (Amharic: ደብረ ሊባኖስ, om, Dabra libanose) is an Ethiopian Orthodox Tewahedo monastery, lying northwest of Addis Ababa in the North Shewa Zone of the Oromia Region. It was founded in 1284 by Saint Tekle Haymanot as Debre Atsbo and was renamed as Debre Libanos in the 15th century. He meditated in a cave above the current monastery for 29 years. The monastery's chief abbot, called the ''Ichege'', was the second most powerful official in the Ethiopian Church after the '' Abuna''. The monastery complex sits on a terrace between a cliff and the gorge of one of the tributaries of the Abbay River (the Blue Nile). None of the original buildings of Debre Libanos survive, although David Buxton suspected "there are interesting things still to be found among the neighbouring cliffs". Current buildings include the church over Tekle Haymanot's tomb, which Emperor Haile Selassie ordered constructed in 1961; a slightly older Church of the Cross, where Buxton was t ...

Lophocebus
The crested mangabeys are West African Old World monkeys belonging to the genus ''Lophocebus''. They tend to have dark skin, eyelids that match their facial skin, and crests of hair on their heads. Another genus of mangabeys, ''Cercocebus'', was once thought to be very closely related, so much so that all the species were placed in one genus. However, ''Lophocebus'' species are now understood to be more closely related to the baboons in genus ''Papio'', while the ''Cercocebus'' species are more closely related to the mandrill. In 2006, the highland mangabey was moved from ''Lophocebus'' to a new genus, ''Rungwecebus The kipunji (''Rungwecebus kipunji''), also known as the highland mangabey, is a species of Old World monkey that lives in the highland forests of Tanzania.

Mangabey
Mangabeys are West-African Old World monkeys, with species in three of the six genera of tribe Papionini. The more typical representatives of ''Cercocebus'', also known as the white-eyelid mangabeys, are characterized by their bare, upper eye-lids which are lighter than their facial skin colouring, and the uniformly coloured hairs of the fur. Members of ''Lophocebus'', the crested mangabeys, tend to have dark skin, eyelids that match their facial skin, and crests of hair on their heads. A new species, the highland mangabey, was discovered in 2003 and was initially placed in ''Lophocebus''. The genus ''Rungwecebus'' was later created for this species. ''Lophocebus'' and ''Cercocebus'' were once thought to be very closely related, so much so that all the species were in one genus. However, the species within genus ''Lophocebus'' are now thought to be more closely related to the baboons in genus '' Papio'', while the species within genus ''Cercocebus'' are more closely related to ...

Mandrillus
''Mandrillus'' is a genus of large Old World monkeys distributed throughout central and southern Africa, consisting of two species: ''M. sphinx'' and ''M. leucophaeus'', the mandrill and drill, respectively. ''Mandrillus'', originally placed under the genus ''Papio'' as a type of baboon, is closely related to the genus ''Cercocebus''. They are characterised by their large builds, elongated snouts with furrows on each side, and stub tails. Both species occupy the west central region of Africa and live primarily on the ground. They are frugivores, consuming both meat and plants, with a preference for plants. ''M. sphinx'' is classified as vulnerable and ''M. leucophaeus'' as endangered on the ''IUCN Red List of Threatened Species''. Taxonomy ''Mandrillus'' is a genus within the tribe Papionini, which in turn is under the subfamily Cercopithecinae. This subfamily is classified under the family of Old World monkeys (Cercopithecidae) within the infraorder Simiiformes. The Papionini ...

Baboon
Baboons are primates comprising the genus ''Papio'', one of the 23 genera of Old World monkeys. 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. Baboons are among the largest non-hominoid primates and have existed for at least two million years. Baboons vary in size and weight depending on the species. The smallest, the Kinda baboon, is in length and weighs only , while the largest, the chacma baboon, is up to in length and weighs . All baboons have long, dog-like muzzles, heavy, powerful jaws with sharp canine teeth, close-set eyes, thick fur except on their muzzles, short tails, and nerveless, hairless pads of skin on their protruding buttocks called ischial callosities that provide for sitting comfort. Male hamadryas baboons have large white man ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monophyly
In cladistics for a group of organisms, monophyly is the condition of being a clade—that is, a group of taxa composed only of a common ancestor (or more precisely an ancestral population) and all of its lineal descendants. Monophyletic groups are typically characterised by shared derived characteristics ( synapomorphies), which distinguish organisms in the clade from other organisms. An equivalent term is holophyly. The word "mono-phyly" means "one-tribe" in Greek. Monophyly is contrasted with paraphyly and polyphyly as shown in the second diagram. A ''paraphyletic group'' consists of all of the descendants of a common ancestor minus one or more monophyletic groups. A '' polyphyletic group'' is characterized by convergent features or habits of scientific interest (for example, night-active primates, fruit trees, aquatic insects). The features by which a polyphyletic group is differentiated from others are not inherited from a common ancestor. These definitions have taken ...

Subspecies
In biological classification, subspecies is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (morphology), but that can successfully interbreed. Not all species have subspecies, but for those that do there must be at least two. Subspecies is abbreviated subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology, under the International Code of Zoological Nomenclature, the subspecies is the only taxonomic rank below that of species that can receive a name. In botany and mycology, under the International Code of Nomenclature for algae, fungi, and plants, other infraspecific ranks, such as variety, may be named. In bacteriology and virology, under standard bacterial nomenclature and virus nomenclature, there are recommendations but not strict requirements for recognizing other important infraspecific ranks. A taxonomist decides whether ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Swartkrans
Swartkrans is a fossil-bearing cave designated as a South African National Heritage Site, located about from Johannesburg. It is located in the Cradle of Humankind World Heritage Site and is notable for being extremely rich in archaeological material, particularly hominin remains. Fossils discovered in the limestone of Swartkrans include ''Homo ergaster'' (a variety of ''Homo erectus''), ''Paranthropus'' and ''Homo habilis''. The oldest deposits present at the site are believed to be between 1.9 and 2.1 million years old. Noted paleontologist Robert Broom was a frequent digger. He was followed by C. K. 'Bob' Brain, whose excavations at the site inspired his book '' The Hunters or the Hunted?'' in which he demonstrated that instead of being bloodthirsty killer apes, the hominin fossils found at the site were themselves victims of predation by big cats. Originally, it was believed that ''Dinofelis'' was responsible for such killings, though recent evidence suggests that hominids ...

Makapansgat
Makapansgat () (or Makapan Valley World Heritage Site) is an archaeological location within the Makapansgat and Zwartkrans Valleys, northeast of Mokopane in Limpopo province, South Africa. It is an important palaeontological site, with the local limeworks containing ''Australopithecus''-bearing deposits dating to between 3.0 and 2.6 million years BP. The whole Makapan Valley has been declared a South African Heritage Site. Makapansgat belongs to the Cradle of Humankind. Makapansgat Valley sites Makapansgat limeworks This is the oldest of the cave sites in the Makapansgat valley, spanning an age of greater than 4.0 million years until perhaps 1.6 million years ago. This site has yielded many thousands of fossil bones, amongst which were found remains of the gracile australopithecine ''Australopithecus africanus''. The ''A. africanus'' fossils are suggested to date to between 2.85 and 2.58 million years ago based on palaeomagnetism by Andy Herries (La Trobe University, Australi ...
