Solimoea
''Solimoea acrensis'' is a prehistoric ateline monkey from the Late Miocene Solimões Formation of Brazil. It is the only known species of the genus ''Solimoea''. Discovery and naming Despite the abundance of primates in modern-day Amazonia, the fossil record of these animals is rather poor with only few specimens having been described from Miocene South America prior to 2006. During a joint expedition between the Universidade Federal do Acre and the University of Rondônia further primate remains where recovered and later described by Richard Kay and Mario Alberto Cozzuol. These remains include the holotype UFAC-LPP 5177, an isolated lower left first molar, and UFAC-LPP 5178, a maxillary fragment containing the 3rd and 4th premolar. Although they represent different parts of the dentition, they are referred to the same species for a series of reasons. Both specimens were found in the same locality and share certain morphological features including the moderately developed shear ...

List Of Fossil Primates Of South America
Various fossil primates have been found in South America and adjacent regions such as Panama and the Caribbean.Tejedor et al., 2013, p.22 Presently, 78 species of New World monkeys have been registered in South America.Rosenberger & Hartwig, 2001, p.2 Around the middle of the Cenozoic, approximately 34 million years ago,Lynch Alfaro et al., 2015, p.519 two types of mammals appeared for the first time in South America: rodents and primates. Both of these groups had already been inhabiting other continents for millions of years and they simply arrived in South America rather than originated there. Analyses of evolutionary relationships have shown that their closest relatives were living in Africa at the time. Therefore, the most likely explanation is that they somehow crossed the Atlantic Ocean, which was less wide than today, landed in South America, and founded new populations of rodents and primates. The first South American primates gave rise to an impressive evolutionary radiati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atelinae
The Atelinae are a subfamily of New World monkeys in the family Atelidae, and includes the various spider and woolly monkeys. 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 Bolivia. Diurnal and arboreal, they move speedily and acrobatically through the trees using their tails. Atelines, along with the related howler monkeys, are the largest of the New World monkeys. They live in groups, show amicable intergroup relations, and can coalesce into large aggregations for extended periods of time. Atelines are frugivore-folivores, their diet consisting primarily of fruits, seeds and leaves, with ''Ateles'' being the most frugivorous, fruits comprising over 80% of their diet. Those species relying most heavily on patchily distributed fruit trees have the largest ranges. These animals are characterized by a slow reproduct ...

Atelidae
The Atelidae are one of the five families of New World monkeys now recognised. It was formerly included in the family Cebidae. Atelids are generally larger monkeys; the family includes the howler, spider, woolly, and woolly spider monkeys (the latter being the largest of the New World monkeys). They are found throughout the forested regions of Central and South America, from Mexico to northern Argentina. Characteristics The Atelidae family consists of monkeys that are small to moderate in size, usually 34 to 72 cm in head-body length, with the howler monkeys being the largest members of the group, and the spider monkeys being the smallest. They have long prehensile tails with a sensitive, almost hairless, tactile pad on the underside of the distal part. The tail is frequently used as 'fifth limb' while moving through the trees where they make their homes. They also have nails on their fingers and toes, enabling them to climb. Most species have predominantly dark brown, g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Huayquerian
The Huayquerian ( es, Huayqueriense) age is a period of geologic time (9.0–6.8 Ma) within the Late Miocene epoch of the Neogene, used more specifically within the SALMA classification. It follows the Mayoan and precedes the Montehermosan age. Etymology The age is named after the Huayquerías Formation in the western Cuyo Basin of northwestern Argentina that was later dated to the Montehermosan. The most complete Huayquerian fauna is found in the Cerro Azul Formation The Cerro Azul Formation ( es, Formación Cerro Azul), in the Buenos Aires Province also described as Epecuén Formation, is a geological formation of Late Miocene (Tortonian, or Huayquerian in the SALMA classification) age in the Colorado Basin ..., in Buenos Aires Province also referred to as Epecuén Formation.

Miocene
The Miocene ( ) is the first geological epoch of the Neogene Period and extends from about (Ma). The Miocene was named by Scottish geologist Charles Lyell; the name comes from the Greek words (', "less") and (', "new") and means "less recent" because it has 18% fewer modern marine invertebrates than the Pliocene has. The Miocene is preceded by the Oligocene and is followed by the Pliocene. As Earth went from the Oligocene through the Miocene and into the Pliocene, the climate slowly cooled towards a series of ice ages. The Miocene boundaries are not marked by a single distinct global event but consist rather of regionally defined boundaries between the warmer Oligocene and the cooler Pliocene Epoch. During the Early Miocene, the Arabian Peninsula collided with Eurasia, severing the connection between the Mediterranean and Indian Ocean, and allowing a faunal interchange to occur between Eurasia and Africa, including the dispersal of proboscideans into Eurasia. During the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stirtonia (mammal)
''Stirtonia'' is an extinct genus of New World monkeys from the Middle Miocene (Laventan in the South American land mammal ages; 13.8 to 11.8 Ma). Its remains have been found at the Konzentrat-Lagerstätte of La Venta in the Honda Group of Colombia. Two species have been described, ''S. victoriae'' and the type species ''S. tatacoensis''.''Stirtonia victoriae'' at .org''Stirtonia tatacoensis'' at |
Lagothrix Lagotricha
The common woolly monkey, brown woolly monkey, or Humboldt's woolly monkey (''Lagothrix lagothricha'') is a woolly monkey from Colombia, Ecuador, Peru, Bolivia, Brazil, and Venezuela. It lives in groups of two to 70 individuals, usually splitting the group into smaller subgroups when active. Taxonomy The taxonomy of the common woolly monkey is still debated. Fooden classified it is as one of two species under the genus ''Lagothrix'' with four sub-species (''L. l. lagotricha'', ''L. l. lugens'', ''L. l. cana'', and ''L. l. poeppgigii''. Later, an analysis of craniodental morphology suggested a move of all sub-species to the species level and also led to the yellow-tailed woolly monkey (formerly ''Lagothrix flavicauda'') being moved to a monotypic genus ''Oreonax''. Genetic analyses also identify distinct groups, but different groupings from morphological and molecular data continue to make this a difficult issue that might be addressed with larger data sets. A 2014 study found th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Protopithecus
''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. Fossils of another large, but less robust ateline monkey, ''Caipora'', were also discovered in Toca da Boa Vista. History Fossils of primates from the New World were unknown for many years despite the large quantities of megafauna fossils that had been found by Europeans since the 1700s. In July 1836, a left proximal femur ( UZM 1623) and a right distal humerus (UZM 3530) were collected by Danish paleontologist Peter Wilhelm Lund, who is commonly hailed as the founder of Brazilian paleontology, from the limestone cave of Lapo de Periperi. Lapo de Periperi is part of the cave networks of Lagoa Santa, Brazil that bear many fossils dating to the Late Pleistocene - Early Holocene. The humerus and femur were both found in the same cavern but not the exact same site, however they ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paralouatta
''Paralouatta'' is a platyrrhine genus that currently contains two extinct species of small primates that lived on the island of Cuba. Description ''Paralouatta varonai'' was described from a nearly complete cranium from the late Quaternary in 1991. This cranium and a number of isolated teeth and postcranial bones were found in the Cueva del Mono, a cave site in Pinar del Río Province. The initial description of the cranium included a proposal that ''Paralouatta varonai'' was a close Caribbean relative of the extant ''Alouatta'' (howler monkeys) of Central and South America, but this taxonomic placement was called into question with the analysis of the dental remains. Based on shared similarities with the three other Caribbean monkeys, '' Xenothrix mcgregori'', '' Insulacebus toussaintiana'', and '' Antillothrix bernensis'', MacPhee and Horovitz have proposed that the Caribbean primates are part of a monophyletic radiation which entered the Caribbean at the Oligocene&ndash ...

Alouatta
Howler monkeys (genus ''Alouatta'', monotypic in subfamily Alouattinae) are the most widespread primate genus in the Neotropics and are among the largest of the platyrrhines along with the muriquis (''Brachyteles''), the spider monkeys (''Ateles'') and woolly monkeys (''Lagotrix''). These monkeys are native to South and Central American forests. They are famous for their loud howls, which can travel more than a mile through dense rain forest. Fifteen species are recognized. Previously classified in the family Cebidae, they are now placed in the family Atelidae. They are primarily folivores but also significant frugivores, acting as seed dispersal agents through their digestive system and their locomotion. Threats include human predation, habitat destruction, and capture for pets or zoo animals.
