Kabirmys qarunensis is an extinct species of anomaluroid (scaly-tailed flying squirrel) 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. [1]
The Anomaluridae are a family of rodents found in central Africa. They are known as anomalures or scaly-tailed squirrels or [African] flying squirrels. The six extant species are classified into two genera.
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 Phiomyidae are a family of prehistoric rodents from Africa and Eurasia. A 2011 study placed Gaudeamus in a new family, Gaudeamuridae.
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.
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.
Dimaitherium is an extinct hyracoid which existed in what is now Egypt, during the late Eocene period. It was first named by Eugenie Barrow, Erik R. Seiffert, and Elwyn L. Simons in 2010. The type species is Dimaitherium patnaiki.
Plesiopithecus is an extinct genus of early strepsirrhine primate from the late Eocene.
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.
Propliopithecoidea is a superfamily of catarrhine primates that inhabited Africa and the Arabian Peninsula 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. They have a number of features in common with extant catarrhines, but also features that are primitive and not found in later catarrhine families.
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.
Masradapis is an extinct genus of caenopithecine primate from the Priabonian Birket Qarun Formation of the Fayum Depression, Egypt. The type and only species, Masradapis tahai, was named and described by Erik R. Seiffert et al., in 2017. Bayesian tip-dating, when combined with Bayesian biogeographic analysis, suggests that a common ancestor of known caenopithecines dispersed to Afro-Arabia from Europe between 49.4 and 47.4 Ma, and that a trans-Tethyan back-dispersal explains Caenopithecus’ later presence in Europe.
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 dinosaurs Mansourasaurus and Igai are known from the formation, as well as the proximal fibula of an indeterminate theropod. Additionally the lungfish genera Lavocatodus and Protopterus, the crocodyliform Wahasuchus and the bothremydid turtle Khargachelys are also known.
Tupelocetus is an extinct genus of early cetacean found in the Bartonian Middle Eocene Tupelo Bay Formation, in Berkeley County, South Carolina.
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.
