Micropithecus
''Micropithecus'' is an extinct genus of primates that lived in East Africa about 19 to 15 million years ago, during the early Miocene. The genus and its type species, ''Micropithecus clarki'', were first scientifically described in 1978.John G. Fleagle and Elwyn L. Simons: ''Micropithecus clarki, a small ape from the Miocene of Uganda.'' In: ''American Journal of Physical Anthropology.'' Vol. 49, No. 4, 1978, pp. 427-440, doi:10.1002/ajpa.1330490402 Naming The generic name, ''Micropithecus'', is derived from the Greek Words μικρός (ancient Greek pronounced ''mikrós'', "small") and πίθηκος (pronounced ''píthēkos'', "monkey"). ''Micropithecus'' thus means "small ape", referring to the fact that the fossils of this genus are among the smallest fossil apes discovered. History of description The holotype of both the genus and type species, ''Micropithecus clarki'', is an upper jaw, which is approximately 19 to 17 million years old, with largely preserved palate ...

Maboko Island
Maboko Island is a small island lying in the Winam Gulf of Lake Victoria, in Nyanza Province of western Kenya. It is about 1.8 km long by 1 km wide. It is an important Middle Miocene paleontological site with fossiliferous deposits that were discovered in the 1930s. The age of the deposits is estimated to be , and they are especially important for the abundance of primate fossils they contain. Excavations Miocene fossils in the fluvial deposits of Maboko was first discovered by Archdeacon W.E. Owen in 1933, who started an excavation later that year which yielded a lot of vertebrate fossils. Owen's excavations continued the following two years supervised by Donald Gordon MacInnes. Then few expeditions visited the island before MacInnes returned together with Louis Leakey in 1947. These excavations resulted in a large number of craniodental (crania and teeth) remains of a medium seized cercopithecoid monkey and cranial and postcranial remains of a large anthropoid ape ...

Miocene
The Miocene ( ) is the first geological epoch of the Neogene Period and extends from about (Ma). The Miocene was named by Scottish geologist Charles Lyell; the name comes from the Greek words (', "less") and (', "new") and means "less recent" because it has 18% fewer modern marine invertebrates than the Pliocene has. The Miocene is preceded by the Oligocene and is followed by the Pliocene. As Earth went from the Oligocene through the Miocene and into the Pliocene, the climate slowly cooled towards a series of ice ages. The Miocene boundaries are not marked by a single distinct global event but consist rather of regionally defined boundaries between the warmer Oligocene and the cooler Pliocene Epoch. During the Early Miocene, the Arabian Peninsula collided with Eurasia, severing the connection between the Mediterranean and Indian Ocean, and allowing a faunal interchange to occur between Eurasia and Africa, including the dispersal of proboscideans into Eurasia. During the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dendropithecus
''Dendropithecus'' is an extinct genus of apes native to East Africa between 20 and 15 million years ago. ''Dendropithecus'' was originally suggested to be related to modern gibbons, based primarily on similarities in size, dentition, and skeletal adaptations. However, further studies have shown that ''Dendropithecus'' lacks derived hominoid traits. Instead, the traits shared between this taxon and modern primates are primitive for all catarrhines. ''Dendropithecus'' is now considered to be a stem catarrhine, too primitive to be closely related to any modern primates. ''Dendropithecus'' was a slender ape, about in body length. The structure of its arms suggest that it would have been able to brachiate Brachiation (from "brachium", Latin for "arm"), or arm swinging, is a form of arboreal locomotion in which primates swing from tree limb to tree limb using only their arms. During brachiation, the body is alternately supported under each forelimb. ..., swinging between trees b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lake Victoria is one of the African Great Lakes. With a surface area of approximately , Lake Victoria is Africa's largest lake by area, the world's largest tropical lake, and the world's second-largest fresh water lake by surface area after Lake Superior in North America.

Propliopithecus
''Propliopithecus'' is an extinct genus of primate. The 40 cm (1 ft 4 in) long creature resembled today's gibbons. Its eyes faced forwards, giving it stereoscopical vision. ''Propliopithecus'' was most likely an omnivore. It is possible that ''Propliopithecus'' is the same creature as ''Aegyptopithecus''. If that would be the case the name ''Propliopithecus'' would take precedence over ''Aegyptopithecus'' according to ICZN rules, because it was coined earlier. Human-like dental features ''Propliopithecus'' had small canine teeth, lacked spaces to fit the canine teeth of the other jaw into, and had molars very similar to those of ''Australopithecus''. These features set ''Propliopithecus'' apart from ''Aegyptopithecus ''Aegyptopithecus'' ("Egyptian ape", from Greek ''Αίγυπτος'' "Egypt" and ''πίθηκος'' "ape") is an early fossil catarrhine that predates the divergence between hominoids ( apes) and cercopithecids (Old World monkeys).

White-fronted Capuchin
White-fronted capuchin can refer to any of a number of species of gracile capuchin monkey which used to be considered as the single species ''Cebus albifrons''. White-fronted capuchins are found in seven different countries in South America: Bolivia, Brazil, Colombia, Venezuela, Ecuador, Peru, and Trinidad and Tobago. White-fronted capuchins are medium-sized monkeys with a light brown back and a creamy white underside. Like other capuchin monkeys, they are omnivorous, feeding primarily on fruits, invertebrates, other plant parts and sometimes small vertebrates. They are predated upon primarily by raptors and probably small cats, especially the margay, though snakes have been known to attack them. They are polygamous primates and live in fairly large groups of 15 to 35 individuals. Reproductive females give birth to a single young at biennial intervals. They maintain home ranges of and have complex vocal repertoires. They are among the few primates to have been observed craftin ...

Gibbon
Gibbons () are apes in the family Hylobatidae (). The family historically contained one genus, but now is split into four extant genera and 20 species. Gibbons live in subtropical and tropical rainforest from eastern Bangladesh to Northeast India to southern China and Indonesia (including the islands of Sumatra, Borneo and Java). Also called the lesser apes, gibbons differ from great apes ( bonobos, chimpanzees, gorillas, orangutans and humans) in being smaller, exhibiting low sexual dimorphism, and not making nests. Like all apes, gibbons are tailless. Unlike most of the great apes, gibbons frequently form long-term pair bonds. Their primary mode of locomotion, brachiation, involves swinging from branch to branch for distances up to , at speeds as fast as . They can also make leaps up to , and walk bipedally with their arms raised for balance. They are the fastest of all tree-dwelling, nonflying mammals. Depending on the species and sex, gibbons' fur coloration varies from dar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
