Killikaike is an extinct genus of New World monkey. The genus includes one species, Killikaike blakei, that lived in Argentina during the Early Miocene. [1]
Killikaike blakei was collected from the Santa Cruz Formation in the far south of Argentina in January, 2005 and the type specimen consists of a remarkably well preserved face. The neurocranium is not present. The specimen was named for the locality where it was found Killik Aike Norte, on the estate of the Blake family. [1]
Perry et al. (2014) considered K. blakei to be a junior synonym of Homunculus patagonicus, which is also known from the Santa Cruz Formation. [2] However, Silvestro at al. (2017) considered Killikaike to be a distinct genus. [3] Kay & Perry (2019) continued to regard the species as synonymous. [4]
Homunculus is an extinct genus of New World monkey that lived in Patagonia during the Miocene. Two species are known: Homunculus patagonicus and Homunculus vizcainoi, which are known from material found in the Santa Cruz Formation in the far south of Argentina.
Chilecebus is an extinct genus of New World monkeys that lived in what is now Chile during the Early Miocene some 20 million years ago. The type species is C. carrascoensis. It had a body mass of about 1,000 g (35 oz).
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.
Paralouatta is a platyrrhine genus that currently contains two extinct species of small primates that lived on the island of Cuba.
Tremacebus is an extinct genus of New World monkeys from the Early Miocene. The type species is T. harringtoni.
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.
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.
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.
Panamacebus is an extinct genus of monkey known from the Early Miocene of central Panama. Panamacebus transitus is the only and type species of this genus.
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 L. 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.
Patasola 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 Patasola magdalenae.
Saimiri annectens, originally described as Laventiana annectens and later as Neosaimiri annectens, is an extinct species of New World monkey in the genus Saimiri from the Middle Miocene. Its remains have been found at the Konzentrat-Lagerstätte of La Venta in the Honda Group of Colombia.
Saimiri fieldsi is an extinct species of New World monkey in the genus Saimiri from the Middle Miocene. Its remains have been found at the Konzentrat-Lagerstätte of La Venta in the Honda Group of Colombia.
The Santa Cruz Formation is a geological formation in the Magallanes/Austral Basin in southern Patagonia in Argentina and in adjacent areas of Chile. It dates to the late Early Miocene epoch, and is contemporaneous with eponymous Santacrucian SALMA. The formation extends from the Andes to the Atlantic coast. In its coastal section it is divided into two members, the lower, fossil rich Estancia La Costa Member, which has a lithology predominantly consisting of tuffaceous deposits and fine grained sedimentary claystone and mudstone, and the upper fossil-poor Estancia La Angelina Member, which consists of sedimentary rock, primarily claystone, mudstone, and sandstone. The environment of deposition is interpreted to have been mostly fluvial, with the lowermost part of the Estancia La Costa Member being transitional between fluvial and marine conditions. The environment of the Estancia La Costa Member is thought to have been relatively warm and humid, but likely became somewhat cooler and drier towards the end of the sequence. The Santa Cruz Formation is known for its abundance of South American native ungulates, as well as an abundance of rodents, xenarthrans, and metatherians.
