Protopithecus is an extinct genus of large New World monkey that lived during the Pleistocene. Fossils have been found in the Toca da Boa Vista cave of Brazil, as well as other locales in the country. [1] Fossils of another large, but less robust ateline monkey, Caipora, were also discovered in Toca da Boa Vista. [2]
These primates are known as platyrrhine (flat-nosed) primates and are closely related to Old World apes and monkeys (catarrhine primates). Platyrrhines include some of the most popular and acrobatic monkeys such as spider monkeys ( Ateles ) and capuchins ( Cebus ), both of which have grasping (prehensile) tails that can be used as a fifth limb.
Atelid monkeys are typically polygamous, and live in social groups with anything up to twenty five adults, depending on species. Where groups are relatively small, as is common amongst the howler monkeys, a single male monopolises a 'harem' of females, but larger groups will contain several males, with a clear hierarchy of dominance.
Caipora was a large-bodied monkey: despite the subadult age of the type specimen, its postcranial skeleton is more robust than any living New World monkey, but not as robust as Protopithecus, and the individual is estimated to have weighed around 20.5 kilograms.
The Atelinae are a subfamily of New World monkeys in the family Atelidae, and includes the various spider and woolly monkeys. [2] The primary distinguishing feature of the atelines is their long prehensile tails, which can support their entire body weight. Atelines live on the American continent from southern Mexico through central Brazil and ...
The primates of Colombia include 41 extant species in 13 genera and five families. [1] [2] [3] [4] Additionally, 12 fossil species in 10 genera and five families have ...
Proteopithecidae is an extinct family of primates which lived in the Priabonian (late Eocene) and probably early Oligocene periods. Fossils that have been found are in the Jebel Qatrani Formation in Egypt.
There are 54 currently recognized extant species of pitheciid monkey, grouped into two subfamilies and six genera. [1] [3] Eleven extinct genera known from the fossil record are placed in the family, extending the age of the family to the Miocene.
