Dimaitherium is an extinct hyracoid which existed in what is now Egypt, during the late Eocene period. [2] It was first named by Eugenie Barrow, Erik R. Seiffert, and Elwyn L. Simons in 2010. [2] The type species is Dimaitherium patnaiki. [2]
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.
The Phiomyidae are a family of prehistoric rodents from Africa and Eurasia. A 2011 study placed Gaudeamus in a new family, Gaudeamuridae.
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 Faiyum Governorate, 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, stout, herbivorous mammals in the order Hyracoidea. Hyraxes are well-furred, rotund animals with short tails. Modern hyraxes are typically between 30 and 70 cm in length and weigh between 2 and 5 kg. They are superficially similar to marmots, or over-large pikas, but are much more closely related to elephants and sea cows. Hyraxes have a life span from 9 to 14 years. Both types of "rock" hyrax live on rock outcrops, including cliffs in Ethiopia and isolated granite outcrops called koppies in southern Africa.
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 is the only known species 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.
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.

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.
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.
The Birket Qarun Formation is an Eocene aged formation in Egypt. It is part of the famous Wadi al Hitan. Notable fossils include the ancient whales Basilosaurus and Dorudon as well as sirenians Eotheroides and Eosiren. It also contains the teeth of various sharks and reptiles. The area was likely a mix of both marine and freshwater area with many freshwater deposits being found alongside a marine influence from the Tethys Sea. Fossils here also preserve a shallow marine nursery for the whale Dorudon and it seems that this area would have also been the site of active predation from Basilosaurus as it attacked the newly born Dorudon calves.
The Fayyum is a region and an important fossil Lagerstätte in northern Egypt. The region comprises the Fayyum Basin, which is intensively used for agriculture, and adjoining areas; the important areas of discovery are mostly north and west of Lake Qarun. The Wadi al-Hitan, known for its numerous whale fossils and since 2005 UNESCO World Natural Heritage Site, forms the south-western end. The deposits of the Fayyum belong to various geological formations. They are mainly composed of limestone, siltstone and sandstone. The lower sections consist of marine sediments, while the upper, continental sediments were formed in a coastal landscape. The formation period ranges from the Middle to the Upper Eocene to the Lower Oligocene, which corresponds to an age of around 41 to 28 million years ago. The entire sedimentary complex is overlain by basalt, which dates back to volcanic activity around 24 million years ago.
