Tremacebus is an extinct genus of New World monkeys from the Early Miocene (Colhuehuapian in the SALMA classification). The type species is T. harringtoni.

Description

Tremacebus was about 1 metre (3.3 ft) in length, and would have resembled a modern night monkey, to which it may have been related, [1] though possibly a stem aotid. [2] However, its eyes appear to have been smaller than the modern species, CT scans of the cranium suggest a relatively small olfactory bulb and poor sense of smell, compared with night monkeys. These features suggest that it may not have been nocturnal. [3] It had an estimated body mass of 1.8 kg (4.0 lb). [2]

Only a few fossils have been found, including a skull from the Sarmiento Formation, Patagonia. [4]

New World monkeys are the five families of primates that are found in the tropical regions of Mexico, Central and South America: Callitrichidae, Cebidae, Aotidae, Pitheciidae, and Atelidae. The five families are ranked together as the Ceboidea, the only extant superfamily in the parvorder Platyrrhini.

Branisella is an extinct genus of New World monkey from the Salla Formation of what is now Bolivia during the Late Oligocene, approximately 26 million years ago (Deseadan), comprising only the species Branisella boliviana. Together with the Peruvian genus Canaanimico, it is the oldest fossil New World monkey discovered.

Xenotrichini is a tribe of extinct primates, which lived on the Greater Antilles as recently as the 16th century.

Stirtonia is an extinct genus of New World monkeys from the Middle Miocene. 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. Synonyms are Homunculus tatacoensis, described by Ruben Arthur Stirton in 1951 and Kondous laventicus by Setoguchi in 1985. The genus is classified in Alouattini as an ancestor to the modern howler monkeys.

<i>Dendropithecus</i> Extinct genus of primates

Dendropithecus is an extinct genus of apes native to East Africa between 20 and 15 million years ago. Dendropithecus was originally suggested to be related to modern gibbons, based primarily on similarities in size, dentition, and skeletal adaptations. However, further studies have shown that Dendropithecus lacks derived hominoid traits. Instead, the traits shared between this taxon and modern primates are primitive for all catarrhines. Dendropithecus is now considered to be a stem catarrhine, too primitive to be closely related to any modern primates.

Acrecebus is a prehistoric cebid monkey from the Late Miocene Solimões Formation of Acre State, Brazil and Bolivia. The only species known is A. fraileyi. This genus is closely related to the genus Cebus.

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.

Aotus dindensis is an extinct species of New World monkeys in the genus Aotus from the Middle Miocene. Its remains have been found at the Konzentrat-Lagerstätte of La Venta in the Honda Group of Colombia.

<span class="mw-page-title-main">Evolution of primates</span> Origin and diversification of primates through geologic time

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.

Nuciruptor is an extinct genus of New World monkeys from the Middle Miocene. Its remains have been found at the Konzentrat-Lagerstätte of La Venta in the Honda Group of Colombia. The type species is N. rubricae.

Cebupithecia is an extinct genus of New World monkeys from the Middle Miocene. Its remains have been found at the Konzentrat-Lagerstätte of La Venta in the Honda Group of Colombia. The type species is C. sarmientoi.

Lagonimico is an extinct genus of New World monkeys from the Middle Miocene. Its remains have been found at the Konzentrat-Lagerstätte of La Venta in the Honda Group of Colombia. The type species is Lagonimico conclucatus.

Micodon is an extinct genus of New World monkeys from the Middle Miocene. Its remains have been found at the Konzentrat-Lagerstätte of La Venta in the Honda Group of Colombia. The type species is M. kiotensis, a very small monkey among the New World species.

Miocallicebus is an extinct genus of New World monkeys from the Middle Miocene. Its remains have been found at the Konzentrat-Lagerstätte of La Venta in the Honda Group of Colombia. The type species is Miocallicebus villaviejai.

Mohanamico is an extinct genus of New World monkeys from the Middle Miocene. Its remains have been found at the Konzentrat-Lagerstätte of La Venta in the Honda Group of Colombia. The type species is M. hershkovitzi. Due to the relatively few material found of Mohanamico, the placement of the genus is not certain and four possible families have been proposed by different authors, Atelidae, Callitrichidae, Pitheciidae or Aotidae.
