Aegyptopithecus is an early fossil catarrhine that predates the divergence between hominoids (apes) and cercopithecids. It is known from a single species, Aegyptopithecus zeuxis, which lived around 38-29.5 million years ago in the early part of the Oligocene epoch. It likely resembled modern-day New World monkeys, and was about the same size as a modern howler monkey, which is about 56 to 92 cm long. Aegyptopithecus fossils have been found in the Jebel Qatrani Formation of modern-day Egypt. Aegyptopithecus is believed to be a stem-catarrhine, a crucial link between Eocene and Miocene fossils.
Oligopithecidae is an extinct basal Catarrhine family from the late Eocene of Egypt as sister of the rest of the Catarrhines. Its members were probably insectivorous due to their simple molars and cusp arrangement.
Witwatia is an extinct genus of giant bat that contained two species which lived in the Al Fayyum in Egypt during the late Eocene and one species which lived in Tunisia during the early Eocene. It is known from a lower jaw and teeth. Three species have been named: the type species W. schlosseri, W. eremicus and W. sigei.
Catopithecus is an early catarrhine fossil. It is known from more than 16 specimens of a single species, Catopithecus browni, found in the Jebel Qatrani Formation of the Fayum Province, Egypt. The Jebel Qatrani Formation has been divided into two main faunal zones based on the fact that the fauna found in the lower portion of the quarry appear to be more primitive than those found in the upper section. The upper zone has been dated to older than 31 ± 1 myr based on the dating of a basalt layer that lies immediately above the formation and Nicolas Steno’s Law of Superposition. The lower zone contains the late Eocene green shale unit called Locality-41 (L-41) in which all the specimens of Catopithecus browni have been found. The relative dating of L-41 based on paleomagnetic correlations places it at 36 Myr according to Simons et al (1999), but Seiffert (2006) suggests this should be revised to 34.8-33.9 Myr.
Karanisia is an extinct genus of strepsirrhine primate from middle Eocene deposits in Egypt.
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 Jebel Qatrani Formation is a geologic formation located in the Faiyum Governorate of central Egypt. It is exposed between the Jebel Qatrani escarpment and the Qasr el Sagha escarpment, north of Birket Qarun lake near Faiyum. The formation conformably overlies the Qasr el Sagha Formation and is topped by the Widan el Faras Basalt. The age of the formation has been subject to debate, but the most recent research indicates that it covers both the latest parts of the Eocene and the Early Oligocene, spanning over the boundary between these two time periods.
Nosmips aenigmaticus is a rare fossil primate known only from 12 teeth. Most teeth were found at a site in the Fayum Depression about 40 miles (64 km) outside Cairo, Egypt.
Hyraxes, also called dassies, are small, thickset, herbivorous mammals in the order Hyracoidea. Hyraxes are well-furred, rotund animals with short tails. Typically, they measure between 30 and 70 cm long and weigh between 2 and 5 kg. They are superficially similar to pikas and marmots, but are more closely related to elephants and sea cows.
Kabirmys qarunensis is an extinct species of anomaluroid rodent from the earliest late Eocene of the Birket Qarun Formation from northern Egypt. So far, it was monotypic in its genus. It was described in September 2010 by Hesham Sallam, Erik Seiffert, Elwyn Simons, and Chlöe Brindley based on isolated teeth, partial mandibles, and an edentulous partial maxilla. It is noteworthy for being the largest known Eocene anomaluroid.
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.
Plesiopithecus is an extinct genus of early strepsirrhine primate from the late Eocene.
Philisidae is an extinct family of bats of the suborder Microchiroptera that lived between the Eocene to the Late Miocene in the continent of Africa.
This paleomammalogy list records new fossil mammal taxa that were described during the year 2010, as well as notes other significant paleomammalogy discoveries and events which occurred during that year.
Widanelfarasia is an extinct genus of placental mammals known from the Late Eocene Jebel Qatrani Formation of Egypt. Two species are known: W. bowni and the smaller W. rasmusseni. Described in 2000 by E. R. Seiffert and Elwyn L. Simons, Widanelfarasia was initially classified as uncertain position within placentals, but was later placed within the afrosoricidan suborder Tenrecomorpha. The genus name derives from Widan el-Faras, two prominent hills in the area where the fossils were recovered.
Megalohyrax is an extinct hyrax-grouped genus of herbivorous mammal that lived during the Miocene, Oligocene, and Eocene, about 55-11 million years ago. Its fossils have been found in Africa and in Asia Minor.
Antilohyrax was a genus of herbivorous mammal belonging to the order Hyracoidea. Fossils were found in 1983 in Egypt, 46 m above the bottom of the Jebel Qatrani Formation. The species Antilohyrax pectidens had an approximate weight of 33–35 kg. It had features not seen in other hyraxes, including a "broad hyper-pectinate comb-like first incisor" on its lower jaw, selenodont molars and a rostrum similar to that seen in even-toed ungulates.
Parapithecoidea is an extinct superfamily of primates which lived in the Eocene and Oligocene periods in Egypt. In some classifications all Parapithecoidea are placed within the family Parapithecidae. Seiffert et al. (2010) propose that Parapithecoidea arose during the Bartonian, with a split between Biretia and the Parapithecidae occurring early in the Priabonian.
Proteopithecidae is an extinct family of primates which lived in the Priabonian and probably early Oligocene periods. Fossils that have been found are in the Jebel Qatrani Formation in Egypt. Currently two genera are recognised, each with a single species, those being Proteopithecus sylviae and Serapia eocaena.
Hesham Sallam is an Egyptian paleontologist and the founder of the Mansoura University Vertebrate Paleontology Center (MUVP-C), the first vertebrate paleontology program in the Middle East. He works as an associate professor at the American University in Cairo and Mansoura University. Sallam led the discovery and description of Mansourasaurus shahinae, a species of sauropod dinosaur from Egypt, which has improved understanding of the prehistory of Africa during the latest Cretaceous period. His work has helped popularize paleontology in Egypt.
