Chiromyiformes is an order of strepsirrhine primates that includes the aye-aye from Madagascar and its extinct relatives.
The simians, anthropoids or, higher primates are an infraorder of primates containing all animals traditionally called monkeys and apes. More precisely, they consist of the parvorders New World monkeys (Platyrrhini) and Catarrhini, the latter of which consists of the superfamilies Old World monkeys in the stricter sense (Cercopithecidae) and apes.
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.
Oligopithecus is a fossil primate that lived in Africa during the Early Oligocene. It is represented by one species, Oligopithecus savagei, known from one jaw bone found in Egypt.
The genus Apidium is that of at least three extinct primates living in the early Oligocene, from 30 to 28 million years ago. Apidium fossils are common in the Fayoum deposits of Egypt. Fossils of the earlier species, Apidium moustafai, are rare; fossils of the later species Apidium phiomense are fairly common.
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.
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.
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.
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.
Djebelemur is an extinct genus of early strepsirrhine primate from the late early or early middle Eocene period from the Chambi locality in Tunisia. Although they probably lacked a toothcomb, a specialized dental structure found in living lemuriforms, they are thought to be a related stem group. The one recognized species, Djebelemur martinezi, was very small, approximately 100 g (3.5 oz).
Plesiopithecus is an extinct genus of early strepsirrhine primate from the late Eocene.
Afradapis is a genus of adapiform primate that lived during the Late Eocene. The only known species, Afradapis longicristatus, was discovered in the Birket Qarun Formation in northern Egypt in 2009. While its geographic distribution is confined to Afro-Arabia, Afradapis belongs to the predominately European adapiform family Caenopithecidae. This taxonomic placement is supported by recent phylogenetic analyses that recover a close evolutionary relationship between Afradapis and adapiforms, including Darwinius. While adapiforms have been noted for their strepsirrhine-like morphology, no adapiform fossil possesses the unique anatomical traits to establish an ancestor-descent relationship between caenopithecids and living strepsirrhines. It ate leaves and moved around slowly like lorises.
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.
Propliopithecoidea is a superfamily of catarrhine primates that inhabited Africa and Arabia during the Early Oligocene about 32 to 29 million years ago. Fossils have been found in Egypt, Oman and Angola. They are one of the earliest known families of catarrhines.
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 Quseir Formation is a geological formation in the vicinity of the Kharga Oasis in Egypt. It is Campanian In age. The lithology largely consists of soft shale with hard bands of sandstone, siltstone and phosphorite. The environment of deposition was nearshore to freshwater fluvio-lacustrine characterized by moist and aquatic habitats with a tropical warm-humid climate. It is conformably overlain by the marine late Campanian-Maastrichtian Duwi Formation, and unconformably overlies the Turonian Taref Formation. The sauropod dinosaur Mansourasaurus is known from the formation, as well as the proximal fibula of an indeterminate theropod. Additionally the lungfish genera Lavocatodus and Protopterus and the Crocodyliform Wahasuchus are also known.
Propotto is an extinct, monotypic genus of early strepsirrhine primate from the early Miocene of Kenya. It contains one described species, Propotto leakeyi. Although long considered a pteropodid fruit-eating bat after spending a brief sojourn as a prehistoric relative of lorises, recent research shows it to be an extinct relative of the aye-aye.
