Apes are a clade of Old World simians native to sub-Saharan Africa and Southeast Asia. Apes are more closely related to Old World monkeys than to the New World monkeys (Platyrrhini) with both Old World monkeys and apes placed in the clade Catarrhini. Apes do not have tails due to a mutation of the TBXT gene. In traditional and non-scientific use, the term ape can include tailless primates taxonomically considered Cercopithecidae, and is thus not equivalent to the scientific taxon Hominoidea. There are two extant branches of the superfamily Hominoidea: the gibbons, or lesser apes; and the hominids, or great apes.
The parvorder Catarrhini consists of the Cercopithecoidea and apes (Hominoidea). In 1812, Geoffroy grouped those two groups together and established the name Catarrhini, "Old World monkeys",. Its sister in the infraorder Simiiformes is the parvorder Platyrrhini. There has been some resistance to directly designate apes 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". The Catarrhini are all native to Africa and Asia. Members of this parvorder are called catarrhines.
Pliopithecus is a genus of extinct primates of the Miocene. It was discovered in 1837 by Édouard Lartet (1801–1871) in France, with fossils subsequently discovered in Switzerland, Slovakia and Spain.
Pierolapithecus catalaunicus is an extinct species of primate which lived around 12.5-13 million years ago during the Miocene in what is now Hostalets de Pierola, Catalonia, Spain. Some researchers believe that it is a candidate for common ancestor to the great ape clade, or is at least closer than any previous fossil discovery. Others suggest it being a pongine, or a dryopith. On 16 October 2023, scientists reported the facial reconstruction of the great ape.
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.
Victoriapithecus macinnesi was a primate from the middle Miocene that lived approximately 15 to 17 million years ago in Northern and Eastern Africa. Through extensive field work on Maboko Island in Lake Victoria, Kenya, over 3,500 specimens have been found, making V. macinnesi one of the best-known fossil primates. It was previously thought that perhaps multiple species of Victoriapithecus were found, however the majority of fossils found indicate there is only one species, V. macinnesi. Victoriapithecus shows similarities to the extant subfamilies Colobinae and Cercopithecinae. However, Victoriapithecus predates the last common ancestor of these two groups and instead is thought to be a sister taxon.
Proconsul major, an extinct primate of the genus Proconsul, was possibly the ancestor of Afropithecus and showed hominid characteristics. It occurred during the early Miocene and was roughly, the size of a gorilla. The species previously referred to as Ugandapithecus major is now considered to be a synonym of Proconsul major. Prior to 2000 it was known as Proconsul major and some argue against the renaming.
Samburupithecus is an extinct primate that lived in Kenya during the middle to late Miocene. The one species in this genus, Samburupithecus kiptalami, is known only from a maxilla fragment dated to 9.5 million years ago discovered in 1982 and formally described by Ishida & Pickford 1997. The type specimen KNM-SH 8531 was discovered by the Joint Japan-Kenya Expedition at the SH22 fossil site in the Samburu District, a locality where several other researchers found no ape fossils.
Dinopithecus is an extinct genus of very large primates closely related to baboons, that lived during the Pliocene and Pleistocene epochs in South Africa and Ethiopia. It was named by British paleontologist Robert Broom in 1937. The only species currently recognized is Dinopithecus ingens, as D. quadratirostris has been reassigned to the genus Soromandrillus. It is known from several infilled cave sites in South Africa, all of early Pleistocene age, including Skurweberg, Swartkrans, and Sterkfontein.
Saadanius is a genus of fossil primates dating to the Oligocene that is closely related to the common ancestor of the Old World monkeys and apes, collectively known as catarrhines. It is represented by a single species, Saadanius hijazensis, which is known only from a single partial skull tentatively dated between 29 and 28 million years ago. It was discovered in 2009 in western Saudi Arabia near Mecca and was first described in 2010 after comparison with both living and fossil catarrhines.
Rangwapithecus is an extinct genus of ape from the Early Miocene of Kenya. Late Miocene phalanges from Hungary have also been assigned to this genus, but were later reclassified as Dryopithecus.
Anapithecus is a late Miocene primate known from fossil locations in Hungary and Austria. Many Anapithecus fossils come from the site of Rudabánya, in northern Hungary, where Anapithecus lived alongside the ape Rudapithecus. The only species in the genus, Anapithecus hernyaki, is named after Gabor Hernyák, chief geologist of the Iron Ore Works of Rudabánya.
The evolutionary history of the primates can be traced back 57-90 million years. One of the oldest known primate-like mammal species, Plesiadapis, came from North America; another, Archicebus, came from China. Other similar basal primates were widespread in Eurasia and Africa during the tropical conditions of the Paleocene and Eocene. Purgatorius is the genus of the four extinct species believed to be the earliest example of a primate or a proto-primate, a primatomorph precursor to the Plesiadapiformes, dating to as old as 66 million years ago.
Pliobates cataloniae is a primate from 11.6 million years ago, during the Iberian Miocene. Originally described as a species of stem-ape that was found to be the sister taxon to gibbons and great apes like humans, it was subsequently reinterpreted as a non-ape catarrhine belonging to the group Crouzeliidae within the superfamily Pliopithecoidea on the basis of discovery of new dental remains with crouzeliid synapomorphies.
Pliopithecoidea is an extinct superfamily of catarrhine primates that inhabited Asia and Europe during the Miocene. Although they were once a widespread and diverse group of primates, the pliopithecoids have no living descendants.
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.
The family Dendropithecidae is an extinct family of catarrhine monkeys. They date from the Early Miocene, around 20 - 12 million years ago.
Epipliopithecus vindobonensis is an extinct species of pliopithecoid primate recovered from the Middle Miocene deposits of Devínska Nová Ves fissure in western Slovakia. Epipliopithecus is one of the few pliopithecoids for which both cranial and post-cranial fossil material has been recovered. Most pliopithecoids are known only from fossilized teeth, whereas Epipliopithecus is known from three nearly complete skeletons. As such, Epipliopithecus has greatly informed the modern understanding of pliopithecoid anatomy, locomotion, and phylogeny.
Micropithecus is an extinct genus of primates that lived in East Africa about 19 to 15 million years ago, during the early Miocene. The genus and its type species, Micropithecus clarki, were first scientifically described in 1978.
Nyanzapithecus is an extinct genus of primate from the Middle Miocene of Maboko Island, Nyanza Province, Kenya. This genus is known from four species. It had an average body mass of around 10 kg (22 lb).
