Honda Group, Colombia
The Honda Group ( es, Grupo Honda, Tsh, Ngh) is a geological group of the Upper and Middle Magdalena Basins and the adjacent Central and Eastern Ranges of the Colombian Andes. The group, in older literature also defined as formation, is in its present-day type section in the Tatacoa Desert in the department of Huila subdivided into two main formations; La Victoria and Villavieja. The group was originally defined in and named after Honda, Tolima, but has been redefined based on the many fossil finds in the Tatacoa Desert, to the south. In the original type section of its occurrence, the thick group is subdivided into three formations, from old to young; Cambrás, San Antonio and Los Limones. The group dates to the Neogene period; in its broadest definition from the Late Oligocene to Late Miocene, and in the redefined type section restricted to the Laventan age of the South American Land Mammal Ages (SALMA), equivalent to the Middle Miocene Serravallian epoch.

Laventan
The Laventan ( es, Laventense) age is a period of geologic time (13.8 to 11.8 Ma) within the Middle Miocene epoch of the Neogene, used more specifically within the SALMA classification in South America. It follows the Colloncuran and precedes the Mayoan age.Madden et al., 1997 Etymology The age is named after the Miocene Lagerstätte La Venta, where a rich biodiversity from the Middle Miocene has been recovered from the Honda Group.

Pitheciidae
The Pitheciidae () are one of the five families of New World monkeys now recognised. Formerly, they were included in the family Atelidae. The family includes the titis, saki monkeys and uakaris. Most species are native to the Amazon region of Brazil, with some being found from Colombia in the north to Bolivia in the south. Characteristics Pithecids are small to medium-sized monkeys, ranging from 23 cm in head-body length for the smaller titis, to 44–49 cm for the uakaris. They have medium to long fur, in a wide range of colors, often with contrasting patches, especially on the face. They are diurnal and arboreal animals, found in tropical forests from low-lying swamp to mountain slopes. They are predominantly herbivorous, eating mostly fruit and seeds, although some species will also eat a small number of insects. Sakis and uakaris have a diastema between the canine and premolar teeth, but the titis, which have unusually small canines for New World monkeys, do ...

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] |
La Venta (Colombia)
La Venta is a fossil locality located in the modern departments of Tolima and Huila in Colombia. This site is one of the richest Neogene fossil assemblages in South America and represents the best-known Cenozoic fossil site outside of Argentina. It provides a glimpse of what life in the region was like before the main wave of the Great American Interchange. Geology The fossils occur in Middle Miocene rocks of the Honda Group, which is divided into the younger Villavieja Formation and the older La Victoria Formation. The La Venta fauna contained ancient species of animal genera and families still alive today, as well as some entirely extinct prehistoric lineages. These animals lived some 13.8 to 12 million years ago in the Laventan age, which was named after La Venta. At that time, the climate of the region was wetter than today and there was much forest of trees similar (and probably related) to the ''sapino'' (''Goupia glabra'') of our time.

South American Land Mammal Age
The South American land mammal ages (SALMA) establish a geologic timescale for prehistoric South American fauna beginning 64.5 Mya (unit), Ma during the Paleocene and continuing through to the Late Pleistocene (0.011 Ma). These periods are referred to as ages, stages, or intervals and were established using geographic place names where fossil materials where obtained.Flynn & Swisher, 1995 The basic unit of measure is the first/last boundary statement. This shows that the first appearance event of one taxon is known to predate the last appearance event of another. If two taxa are found in the same fossil quarry or at the same stratigraphic horizon, then their age-range zones overlap. Background South America was an island continent for much of the Cenozoic, or the "Age of Mammals". As a result, its mammals evolved in their own unique directions, as Australia and Madagascar still have today.

Mohanamico
''Mohanamico'' 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. 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. Etymology ''Mohanimico hershkovitzi'' is named after the river god Mohan of the Magdalena River, in which valley the fossils were found and to honor Philip Hershkovitz for his contributions to the study of Colombian and other South American primates.Luchterhand et al., 1986, p.1757 Description Fossils of ''Mohanamico'' were discovered in the "Monkey Beds" of the Honda Group, that has been dated to the Laventan, about 12.5 Ma.Wheeler, 2010, p.133 ''Mohanamico'' was about ...
