Biretia
''Biretia'' is an extinct genus of Old World monkey belonging to the extinct family Parapithecidae. Fossils are found from Late Eocene strata in Egypt. The first discovery of ''Biretia'' was a single tooth dated to approximately 37 mya, which was found in 1988 at the Bir el Ater site in Algeria. This species was named ''Biretia piveteaui''. In 2005, two new species were classified, ''B. fayumensis'' and ''B. megalopsis''. Both were discovered at Birket Qarun Locality 2 (BQ-2), which is located about 60 mi south of Cairo in Egypt's Fayum depression. A very small anthropoid, it only weighed around 280 to possibly 380 grams. Fragments from the jaw suggest that it had had very large eyes in proportion to its body size, which would suggest that it was nocturnal. ''Biretia'' is unique among early anthropoids in exhibiting evidence for nocturnality, but derived dental features shared with younger parapithecids draw this genus, and possibly 45-million-year-old ''Algeripithecus ...

Parapithecidae
Parapithecidae is an extinct family of primates which lived in the Eocene and Oligocene periods in Egypt. Eocene fossils from Myanmar are sometimes included in the family in addition. They showed certain similarities in dentition to Condylarthra, but had short faces and jaws shaped like those of tarsiers. They are part of the superfamily Parapithecoidea, perhaps equally related to Ceboidea and Cercopithecoidea plus Hominoidea - but the placement of Parapithecoidea is substantially uncertain. The most commonly found fossil species of parapithecid is '' Apidium phiomense'', found like many of the species in the Jebel Qatrani Formation in Egypt. It appears to have been arboreal, diurnal and frugivorous and lived in social groups, and its postcranial skeleton is similar to that of extant species of pronograde leapers, indicating its likely form of locomotion.Seiffert, Erik & Simons, Elwyn & Fleagle, John & Godinot, Marc.

Anthrasimias
''Marcgodinotius'' is a genus of adapiform primate that lived in Asia during the early Eocene. It is a monotypic genus, the only species being ''Marcgodinotius indicus''. Another adapiform primate ''Suratius robustus'' was found in the same horizon. ''Anthrasimias'' may be a junior synonym of ''Marcgodinotius'' and ''Anthrasimias gujaratensis'' a junior synonym of ''Marcgodinotius indicus''. ''Marcgodinotius indicus'' was a species of primate first found in Gujarat, India in 2005. It is believed to have lived about 55 million years ago, during the early Eocene. It weighed around 75 grams which would make it only slightly larger than the world's smallest primates, the mouse lemurs and the dwarf galagos. The generic name, ''Anthrasimias'', referred to , Greek for coal, because the fossils were found in a coal mine and , Latin for monkey or ape.

Ganlea
''Ganlea'' is a fossil primate from central Myanmar, formerly known as Burma. Its age is about 38 million years, living during the late Eocene epoch. ''Ganlea'' belongs to the group of anthropoids (i. e. humans, apes and monkeys), and is in the family Amphipithecidae. It is older than any other known anthropoid from Africa, and is the second oldest known from Asia. Its remains consist of teeth and jawbones belonging to 10 to 15 individuals found near the city of Bagan in the central part of the country. The teeth of ''Ganlea'' have many diagnostic features that help to show its relations with other anthropoids. It is thought to be closely related to the genera '' Myanmarpithecus'', '' Pondaungia'' and '' Siamopithecus'', both found from the same area as ''Ganlea''. In all of these genera, the canine tooth is enlarged and compressed anteroposteriorly, making it quite wide. A great deal of tooth wear has been observed in ''Ganlea'', which has been viewed as an adaptation for cons ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eocene
The Eocene ( ) Epoch is a geological epoch that lasted from about 56 to 33.9 million years ago (mya). It is the second epoch of the Paleogene Period in the modern Cenozoic Era. The name ''Eocene'' comes from the Ancient Greek (''ēṓs'', " dawn") and (''kainós'', "new") and refers to the "dawn" of modern ('new') fauna that appeared during the epoch. The Eocene spans the time from the end of the Paleocene Epoch to the beginning of the Oligocene Epoch. The start of the Eocene is marked by a brief period in which the concentration of the carbon isotope 13C in the atmosphere was exceptionally low in comparison with the more common isotope 12C. The end is set at a major extinction event called the ''Grande Coupure'' (the "Great Break" in continuity) or the Eocene–Oligocene extinction event, which may be related to the impact of one or more large bolides in Siberia and in what is now Chesapeake Bay. As with other geologic periods, the strata that define the start and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Old World Monkey
Old World monkey is the common English name for a family of primates known taxonomically as the 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, surili ('' Presbytis''), patas, and proboscis monkey. Phylogenetically, they are more closely related to apes than to New World monkeys. They diverged from a common ancestor of New World monkeys around 45 to 55 million years ago. The smallest Old World monkey is the talapoin, with a head and body 34–37 cm in length, and weighing between 0.7 and 1.3 kg. The largest is the male mandrill, around 70 cm in length, and weighing up to 50&nbs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opin ...

Egypt
Egypt ( ar, مصر , ), officially the Arab Republic of Egypt, is a transcontinental country spanning the northeast corner of Africa and southwest corner of Asia via a land bridge formed by the Sinai Peninsula. It is bordered by the Mediterranean Sea to the north, the Gaza Strip of Palestine and Israel to the northeast, the Red Sea to the east, Sudan to the south, and Libya to the west. The Gulf of Aqaba in the northeast separates Egypt from Jordan and Saudi Arabia. Cairo is the capital and largest city of Egypt, while Alexandria, the second-largest city, is an important industrial and tourist hub at the Mediterranean coast. At approximately 100 million inhabitants, Egypt is the 14th-most populated country in the world. Egypt has one of the longest histories of any country, tracing its heritage along the Nile Delta back to the 6th–4th millennia BCE. Considered a cradle of civilisation, Ancient Egypt saw some of the earliest developments of writing, agriculture ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Algeripithecus
''Algeripithecus'' is an extinct genus of early fossil primate, weighing approximately . Fossils have been found in Algeria dating from 50 to 46 million years ago. It was once commonly thought to be one of the oldest simian primates (a group that includes monkeys and apes), and was crucial to the hypothesis that simians originated in Africa. Research on more complete specimens suggest it was instead a strepsirrhine primate, more closely related to living lemurs and lorisoids. However, this is still disputed. Discovery Fragmentary fossils were first found in the Glib Formation at the Glib Zegdou locality in Algeria and dated to the Early to Middle Eocene, 50 to 46 million years ago. The holotype was an upper left molar (M2). Evolutionary history and taxonomy First described in the journal ''Nature'' by Marc Godinot and Mohamed Mahboubi in 1992, ''Algeripithecus'' was once widely considered one of the oldest known fossil simian primates, giving weight to the African origin ...

Strepsirrhini
Strepsirrhini or Strepsirhini (; ) is a suborder of primates that includes the lemuriform primates, which consist of the lemurs of Madagascar, galagos ("bushbabies") and pottos from Africa, and the lorises from India and southeast Asia. Collectively they are referred to as strepsirrhines. Also belonging to the suborder are the extinct adapiform primates which thrived during the Eocene in Europe, North America, and Asia, but disappeared from most of the Northern Hemisphere as the climate cooled. Adapiforms are sometimes referred to as being "lemur-like", although the diversity of both lemurs and adapiforms does not support this comparison. Strepsirrhines are defined by their "wet" (moist) rhinarium (the tip of the snout) – hence the colloquial but inaccurate term "wet-nosed" – similar to the rhinaria of canines and felines. They also have a smaller brain than comparably sized simians, large olfactory lobes for smell, a vomeronasal organ to detect pheromones, and a bic ...

Africa
Africa is the world's second-largest and second-most populous continent, after Asia in both cases. At about 30.3 million km2 (11.7 million square miles) including adjacent islands, it covers 6% of Earth's total surface area and 20% of its land area.Sayre, April Pulley (1999), ''Africa'', Twenty-First Century Books. . With billion people as of , it accounts for about of the world's human population. Africa's population is the youngest amongst all the continents; the median age in 2012 was 19.7, when the worldwide median age was 30.4. Despite a wide range of natural resources, Africa is the least wealthy continent per capita and second-least wealthy by total wealth, behind Oceania. Scholars have attributed this to different factors including geography, climate, tribalism, colonialism, the Cold War, neocolonialism, lack of democracy, and corruption. Despite this low concentration of wealth, recent economic expansion and the large and young population make Afric ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eurasia
Eurasia (, ) is the largest continental area on Earth, comprising all of Europe and Asia. Primarily in the Northern and Eastern Hemispheres, it spans from the British Isles and the Iberian Peninsula in the west to the Japanese archipelago and the Russian Far East to the east. The continental landmass is bordered by the Atlantic Ocean and Africa to the west, the Pacific Ocean to the east, the Arctic Ocean to the north, and by Africa, the Mediterranean Sea, and the Indian Ocean to the south. The division between Europe and Asia as two continents is a historical social construct, as many of their borders are over land; thus, in some parts of the world, Eurasia is recognized as the largest of the six, five, or four continents on Earth. In geology, Eurasia is often considered as a single rigid megablock. However, the rigidity of Eurasia is debated based on paleomagnetic data. Eurasia covers around , or around 36.2% of the Earth's total land area. It is also home to the lar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
