Xenastrapotherium
''Xenastrapotherium'' is an extinct genus of astrapothere, a type of hoofed herbivorous mammal, native to South America, which lived in the Middle to Late Miocene period, typically during the Laventan stage. It is a member of the family Astrapotheriidae in the subfamily Uruguaytheriinae, large astrapotheres, equipped with a trunk-like nose and protruding teeth, similar to the elephants, but their tusks were the canine teeth, not the incisors. ''Xenastrapotherium'' (named after the Greek word ''xenos'' "strange" add to the genus ''Astrapotherium'', "lightning beast") was a genus widely distributed in northern South America, in contrast to other species of astrapotheres which lived in the area of the Southern Cone of the continent. It differed from other astrapotheres by having two lower incisors on each side of the jaw and the tusks have a pronounced longitudinal curvature, although their general shape and size are probably very similar to ''Astrapotherium'', whose weight would ...

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.

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 ...

Astrapotheriidae
Astrapotheriidae is an extinct family of herbivorous South American land mammals that lived from the Late Eocene (Mustersan SALMA) to the Middle Miocene (Laventan SALMA) . The most derived of the astrapotherians, they were also the largest and most specialized mammals in the Tertiary of South America. There are two sister taxa: Eoastrapostylopidae and Trigonostylopidae. Around 1900, Argentine paleontologist Florentino Ameghino described eight Colhuehuapian (Early Miocene) species from specimens he found south of Lake Colhué Huapi in Patagonia and grouped them into three genera: '' Parastrapotherium'', '' Astrapotherium'', and '' Astrapothericulus''. It was obvious to Ameghino that these species represented a great diversity, ranging in size from a peccary to a rhinoceros, but his description was based entirely on fragmentary and not always comparable dental remains. Other expeditions to Patagonia have subsequently recovered considerably more complete materials. Genera Accor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Granastrapotherium
''Granastrapotherium'' is an extinct genus of ungulate mammals, described from remains found in rocks of the Honda Group in the Tatacoa Desert, in the Colombian departments of Huila and Tolima, at the Miocene fossil site La Venta. The only species formally recognized is ''Granastrapotherium snorki'' (from Spanish, ''gran'', "great"; ''Astrapotherium'', "lightning beast"; and snorkel, breathing tube, in reference to the trunk). Remains found in Bolivia and Peru, seem to belong to ''Granastrapotherium'' or a very similar animal. Description This astrapothere differs from its coeval, the uruguaytheriine astrapotheriid ''Xenastrapotherium'' by their larger size, between 3 and 4 tonnes, with tusks about one meter long, making it one of the largest representatives of Astrapotheria, only surpassed by some species of ''Parastrapotherium''. Other differences include the presence of only one premolar, the lack of incisors in both jaws and the disposition of the canine tooth, which ar ...

Huayquerian
The Huayquerian () 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 Chasicoan 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 Montehermosan age is a period of geologic time (6.8–4.0 Mya (unit), Ma) within the Miocene and Pliocene epochs of the Neogene used more specifically with South American Land Mammal Ages. It follows the Huayquerian and precedes the Chapadmalal .... The most complete Huayquerian fauna is found in the Cerro Azul Formation, in Buenos Aires Province also referred to as Epecuén Formation.

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.

Astrapotheria
Astrapotheria is an extinct order of South American and Antarctic hoofed mammals that existed from the late Paleocene to the Middle Miocene, ."The uruguaytheriine Astrapotheriidae from the rich middle Miocene Honda Group of the upper Magdalena River valley in Colombia (...) are the youngest securely dated remains of that order in South America." Astrapotheres were large, rhinoceros-like animals and have been called one of the most bizarre orders of mammals with an enigmatic evolutionary history. The taxonomy of this order is not clear, but it may belong to Meridiungulata (along with Notoungulata, Litopterna, Pyrotheria and Xenungulata). In turn, Meridungulata is believed to belong to the extant superorder Laurasiatheria. Some scientists have regarded the astrapotheres (and sometimes the Meridiungulata as a whole) as members of the clade Atlantogenata. However, collagen and mitochondrial DNA sequence data analysed in 2015 places at least the notoungulates and litopterns firmly w ...

Department Of Huila
Huila () is one of the departments of Colombia. It is located in the southwest of the country, and its capital is Neiva. Demography and Ethnography Huila department had a population of 1,122,622 inhabitants in 2020, of which 679,667 (60.54%) live in urban areas and 442,955 (39.46%) in the rest of the ''Huilense'' territory. This amounts to 2.5% of the total Colombian population. The majority of it is settled in the Magdalena valley, the main urban centers being Neiva and Garzón, due to the possibilities offered by commercial-type agricultural economy, oil production, access to basic public services and roads connected to the central road axis along the Magdalena. The rest of the population is located on the coffee belt, standing out Pitalito and La Plata; the North Subregion is undergoing a decrease in its rural population, mainly attributable to alterations of agricultural and oil activities on the landscape. The average population density in the department is 59.88 inhabit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
