Catopithecus2020
''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.

Catarrhine
The parvorder Catarrhini (known commonly as catarrhine monkeys, Old World anthropoids, or Old World monkeys) consists of the Cercopithecoidea and apes (Hominoidea). In 1812, Geoffroy grouped those two groups together and established the name Catarrhini, "Old World monkeys", ("''singes de l'Ancien Monde''" in French). Its sister in the infraorder Simiiformes is the parvorder Platyrrhini (New World monkeys). There has been some resistance to directly designate apes (and thus humans) as monkeys despite the scientific evidence, so "Old World monkey" may be taken to mean the Cercopithecoidea or the Catarrhini. That apes are monkeys was already realized by Georges-Louis Leclerc, Comte de Buffon in the 18th century. Linnaeus placed this group in 1758 together with what we now recognise as the tarsiers and the New World monkeys, in a single genus "''Simia''" (sans ''Homo''). The Catarrhini are all native to Africa and Asia. Members of this parvorder are called catarrhines. The Catarrh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jebel Qatrani Formation
The Jebel Qatrani Formation (also Gebel Qatrani, Gabal Qatrani or Djebel Qatrani) 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. The geology and fauna of this formation gives a good idea of the environment and animals present during this time period. Research suggests that the Jebel Qatrani Formation featured a mix of subtropical to tropical forest, lowland swamps and marshes, ponds and rivers that would empty northward into the Tethys Sea. This is supported by the presence of water-dependent fauna inc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Faiyum Governorate
Faiyum ( ) is one of the governorates of Egypt in the middle of the country. Its capital is the city of Faiyum, located about 81 mi (130 km) south west of Cairo. It has a population of 3,848,708 (2020). Etymology The name Faiyum comes from Coptic language, Coptic / ''efiom/peiom'' (whence the proper name ), meaning ''the Sea'' or ''the Lake'', which in turn comes from late Egyptian language, Egyptian ''pA y-m'' of the same meaning, a reference to the nearby Lake Moeris. Overview The rate of poverty is more than 60% in this governorate but recently some social safety networks have been provided in the form of financial assistance and job opportunities. The funding has been coordinated by the Ministry of Finance (Egypt), country's Ministry of Finance and with assistance from international organizations. Municipal divisions The governorate is divided into the following Subdivisions of Egypt#Municipal divisions, municipal divisions for administrative purposes, with a ...

Nicolas Steno
Niels Steensen (; Latinized to Nicolas Steno or Nicolaus Stenonius; 1 January 1638 – 25 November 1686 ) was a Danish scientist, a pioneer in both anatomy and geology who became a Catholic bishop in his later years. He has been beatified by the Catholic Church. Steensen was trained in the classical texts on science; however, by 1659 he seriously questioned accepted knowledge of the natural world. Importantly he questioned explanations for tear production, the idea that fossils grew in the ground and explanations of rock formation. His investigations and his subsequent conclusions on fossils and rock formation have led scholars to consider him one of the founders of modern stratigraphy and modern geology. The importance of Steensen's foundational contributions to geology may be gauged from the fact that half of the twenty papers in a recent miscellany volume on ''The Revolution in Geology from the Renaissance to the Enlightenment'' focus on Steensen, the "preeminent Baroqu ...

Ectotympanic
The ectotympanic, or tympanicum, is a bony structure found in all mammals, located on the tympanic part of the temporal bone, which holds the tympanic membrane (eardrum) in place. In catarrhine primates (including humans), it takes a tube-shape. Its position and attachment to the skull vary between primates, and can be either inside or outside the auditory bulla. It is homologous with the angular bone of non-mammalian tetrapods A tetrapod (; from Ancient Greek τετρα- ''(tetra-)'' 'four' and πούς ''(poús)'' 'foot') is any four- limbed vertebrate animal of the clade Tetrapoda (). Tetrapods include all extant and extinct amphibians and amniotes, with the lat .... When the latter is present, it contacts the entotympanic.

Oligopithecidae

Eocene Primates
The Eocene ( ) is a geological epoch that lasted from about 56 to 33.9 million years ago (Ma). 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.See: *Letter from William Whewell to Charles Lyell dated 31 January 1831 in: * From p. 55: "The period next antecedent we shall call Eocene, from ήως, aurora, and χαινος, recens, because the extremely small proportion of living species contained in these strata, indicates what may be considered the first commencement, or ''dawn'', of the existing state of the animate creation." 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 com ...
