Neotamandua
''Neotamandua'' is an extinct genus of anteaters that lived in the Miocene to Pliocene in South America. Taxonomy Their fossils have been found in the Miocene Collón Cura Formation of Argentina, the Honda Group at La Venta in Colombia and the Pliocene Araucano Formation in Argentina. Its closest living relatives are the giant anteater (''Myrmecophaga tridactyla'') and tamandua ''Tamandua'' is a genus of anteaters in the Myrmecophagidae family with two species: the southern tamandua (''T. tetradactyla'') and the northern tamandua (''T. mexicana''). They live in forests and grasslands, are semiarboreal, and possess part ...s (genus ''Tamandua''). The species '' Neotamandua borealis'' was suggested to be an ancestor of the giant anteater. Patterson (1992) suggested the ''Neotamandua'' fossils are very similar to ''Myrmecophaga'', which would mean ''Neotamandua'' may be congeneric with ''Myrmecophaga''.

Neotamandua Borealis
''Neotamandua borealis'' is an extinct species of anteater. Fossils were found in the Honda Group at the Konzentrat-Lagerstätte of La Venta, Colombia. It was suggested to be an ancestor of the giant anteater, and is also related to the tamanduas.

Giant Anteater
The giant anteater (''Myrmecophaga tridactyla'') is an Insectivore, insectivorous mammal native to Central America, Central and South America. It is the largest of the four living species of anteaters, which are classified with sloths in the order (biology), order Pilosa. The only extant member of the genus ''Myrmecophaga'', the giant anteater is mostly terrestrial, in contrast to other living anteaters and sloths, which are arboreal or semiarboreal. The species is in length, with weights of for males and for females. It is recognizable by its elongated snout, bushy tail, long foreclaws, and distinctively colored fur. The giant anteater is found in multiple habitats, including grassland and rainforest. It forages in open areas and rests in more forested habitats. It feeds primarily on ants and termites, using its foreclaws to dig them up and its long, sticky tongue to collect them. Though giant anteaters live in overlapping home ranges, they are mostly solitary except during ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Honda Group, Colombia
The Honda Group (, Tsh, Ngh) is a group (geology), geological group of the Upper Magdalena Basin, Upper and Middle Magdalena Basins and the adjacent Cordillera Central (Colombia), Central and Cordillera Oriental (Colombia), 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 departments of Colombia, department of Huila Department, Huila subdivided into two main formations; La Victoria and Villavieja. The group was originally defined in and named after Honda, Tolima, 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 Oligocene, Late Oligocene to Miocene, Late Miocene, and in the redefine ...

Laventan
The Laventan () 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. 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.

Anteater
Anteaters are the four extant mammal species in the suborder Vermilingua (meaning "worm tongue"), commonly known for eating ants and termites. The individual species have other names in English and other languages. Together with sloths, they are within the order Pilosa. The name "anteater" is also commonly applied to the aardvark, numbat, echidnas, and pangolins, although they are not closely related to them. Extant species are the giant anteater ''Myrmecophaga tridactyla'', about long including the tail; the silky anteater ''Cyclopes didactylus'', about long; the southern tamandua or collared anteater ''Tamandua tetradactyla'', about long; and the northern tamandua ''Tamandua mexicana'' of similar dimensions. Etymology The name ''anteater'' refers to the species' diet, which consists mainly of ants and termites. Anteater has also been used as a common name for a number of animals that are not in Vermilingua, including the echidnas, numbat, pangolins, and aardvark. Anteate ...

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.

Miocene Mammals Of South America
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 followed the Oligocene and preceded 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 distinct global events but by regionally defined transitions from the warmer Oligocene to the cooler Pliocene Epoch. During the Early Miocene, Afro-Arabia collided with Eurasia, severing the connection between the Mediterranean and Indian Oceans, and allowing the interchange of fauna between Eurasia and Africa, including the dispersal of proboscideans and hominoids into Eurasia. During the late Miocene, the connections between the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
