Panthera Onca Mesembrina
''Panthera onca mesembrina'' is an extinct subspecies of the jaguar that was endemic to southern South America during the Pleistocene epoch (1.8 mya–11,000 years ago). Its fossils have been excavated primarily in Argentina and Chile, though few fossils are known. Genetic analysis in 2016 showed that ''P. onca mesembrina'' was in an extinct sister lineage to extant ''Panthera onca'' species based on genetic evidence, and is the largest known subspecies of jaguar. History and taxonomy In the 1890s in the “Cueva del Milodon” in southern Chile, fossil collector Rodolfo Hauthal collected a fragmentary postcranial skeleton of a large Felid that he sent to Santiago Roth who described them as a new genus and species of Felid, "Iemish listai", in 1899, though the name is considered a nomen nudum. 5 years later in 1904, Roth reassessed the phylogenetic affinities of “Iemish” and moved the species to ''Felis,'' referring several cranial and fragmentary postcranial elements to ...

Pleistocene
The Pleistocene ( , often referred to as the ''Ice age'') is the geological Epoch (geology), epoch that lasted from about 2,580,000 to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations. Before a change was finally confirmed in 2009 by the International Union of Geological Sciences, the cutoff of the Pleistocene and the preceding Pliocene was regarded as being 1.806 million years Before Present (BP). Publications from earlier years may use either definition of the period. The end of the Pleistocene corresponds with the end of the last glacial period and also with the end of the Paleolithic age used in archaeology. The name is a combination of Ancient Greek grc, label=none, πλεῖστος, pleīstos, most and grc, label=none, καινός, kainós (latinized as ), 'new'. At the end of the preceding Pliocene, the previously isolated North and South American continents were joined by the Isthmus of Panama, causing Great American Interchang ...

Última Esperanza Province
Última Esperanza ( es, Provincia de Última Esperanza, meaning "Last Hope Province") is one of four provinces in the southern Chilean region of Magallanes and Antártica Chilena. The capital is Puerto Natales and it is named after Última Esperanza Sound. A section of its border with Argentina in the Southern Patagonian Ice Field is under dispute. Administration As a province, Última Esperanza is a second-level administrative division of Chile, which is further divided into two communes (''comunas''): Puerto Natales and Torres del Paine. The province is administered by a presidentially appointed governor. Ana Ester Mayorga Bahamonde was appointed governor by president Sebastián Piñera. Noted features Within this province, the noted Torres del Paine National Park, Cerro Torre and Cerro Chaltén is located, comprising some of the most spectacular mountain peaks of South America. Also part of the biggest non-polar glacier, the Southern Patagonian Ice Field is within Última Es ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hippidion
''Hippidion'' (meaning ''little horse'') is an extinct genus of Equinae, equine that lived in South America from the Late Pliocene to the end of the Late Pleistocene (Lujanian), between two million and 11,000 years ago. They were one of two lineages of equines native to South America during the Pleistocene epoch, alongside those of the ''Equus (genus), Equus'' subgenus ''Amerhippus''. Evolution ''Hippidion'' has been considered a Lineal descendant, descendant of Evolution of the horse#Pliohippus, pliohippines, equines that migrated into the South American continent around 2.5 million years ago. Early analysis of the ancient DNA of ''Hippidion'' and other New World Pleistocene equines supported the novel hypothesis that ''Hippidion'' was actually a member of the living genus ''Equus (genus), Equus'', with a particularly close relationship to the wild horse, ''Equus ferus''. However this was later shown to be incorrect, with more complete sequences finding ''Hippidion'' as an ou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mylodon
''Mylodon'' is a genus of extinct ground sloth belonging to the family Mylodontidae, known from the region of Patagonia in Chile and Argentina in southern South America. With a total length of 3 to 4 m, it is one of the best-known and largest representatives of the group. The oldest finds probably date to the Lower Pleistocene; however, most of the fossil remains date from the Upper Pleistocene period. One of the most important sites of this phase is the Cueva del Milodón in southern Chile. Shortly after, about 10,200 BP, ''Mylodon'' became extinct. At this point in time, it coexisted with the first human colonists in America. However, there is little evidence that it was hunted by humans. In ''Mylodons case, not only bones and teeth are known, but also various soft tissue and integumentary structures are preserved. The diet of ''Mylodon'' is known in great detail due to fossilized faeces. Its skull is greatly elongated and, compared to other large mylodontids, is narrower, posse ...

Indigenous Peoples Of South America
The Indigenous peoples of South America or South American Indigenous peoples, are the pre-Colombian peoples of South America and their descendants. These peoples contrast with South Americans of European ancestry and those of African descent. In Spanish, Indigenous people are often referred to as ''indígenas'' or ''pueblos indígenas'' (lit. Indigenous peoples). They may also be called ''pueblos nativos'' or ''nativos'' (lit. Native peoples). The term ''aborigen'' (lit. aborigine) is used in Argentina and ''pueblos aborígenes'' (lit. aboriginal peoples) is commonly used in Colombia. The English term "Amerindian" (short for "Indians of the Americas") is often used in the Guianas. Latin Americans of mixed European and Indigenous descent are usually referred to as mestizos (Spanish) and mestiços (Portuguese). While those of mixed African and Indigenous ancestry are referred to as zambos. It is believed that the first human populations of South America either arrived from Asia ...

Guanaco
The guanaco (; ''Lama guanicoe'') is a camelid native to South America, closely related to the llama. Guanacos are one of two wild South American camelids, the other being the vicuña, which lives at higher elevations. Etymology The guanaco gets its name from the Quechua word ''huanaco'' (modern spelling ''wanaku''). Young guanacos are called ''chulengos''. Characteristics Guanacos stand between at the shoulder, body length of , and weigh . Their color varies very little (unlike the domestic llama), ranging from a light brown to dark cinnamon and shading to white underneath. Guanacos have grey faces and small, straight ears. The lifespan of a guanaco can be as long as 28 years. Guanacos are one of the largest terrestrial mammals native to South America today.San Diego Zoo's Animal Bytes Other terrestrial mammali ...

Santa Cruz Province, Argentina
Santa Cruz Province ( es, Provincia de Santa Cruz, , 'Holy Cross') is a province of Argentina, located in the southern part of the country, in Patagonia. It borders Chubut Province to the north, and Chile to the west and south, with an Atlantic coast on its east. Santa Cruz is the second-largest province of the country (after Buenos Aires Province), and the least densely populated in mainland Argentina. The indigenous people of the province are the Tehuelches, who despite European exploration from the 16th century onwards, retained independence until the late 19th century. Soon after the Conquest of the Desert in the 1870s, the area was organised as the Territory of Santa Cruz, named after its original capital in Puerto Santa Cruz. The capital moved to Rio Gallegos in 1888 and has remained there ever since. Immigrants from various European countries came to the territory in the late 19th and early 20th century during a gold rush. Santa Cruz became a province of Argentina in 1957. ...

Cave Painting
In archaeology, Cave paintings are a type of parietal art (which category also includes petroglyphs, or engravings), found on the wall or ceilings of caves. The term usually implies prehistoric origin, and the oldest known are more than 40,000 years old (art of the Upper Paleolithic), found in the caves in the district of Maros ( Sulawesi, Indonesia). The oldest are often constructed from hand stencils and simple geometric shapes.M. Aubert et al., "Pleistocene cave art from Sulawesi, Indonesia", ''Nature'' volume 514, pages 223–227 (09 October 2014). "using uranium-series dating of coralloid speleothems directly associated with 12 human hand stencils and two figurative animal depictions from seven cave sites in the Maros karsts of Sulawesi, we show that rock art traditions on this Indonesian island are at least compatible in age with the oldest European art. The earliest dated image from Maros, with a minimum age of 39.9 kyr, is now the oldest known hand stencil in the world. In ...

Panthera Onca Augusta
''Panthera onca augusta'', commonly known as the Pleistocene jaguar or simply the giant jaguar, is an extinct subspecies of the jaguar that was endemic to North America during the Pleistocene epoch (1.8 mya–11,000 years ago). History and distribution Although '' P. onca'' still resides in the southern United States and several Native American tales possibly about ''P. onca augusta'' exist, the first published remains were described in 1872. The fossils were found by Ferdinand Vandeveer Hayden on the Platte River of Nebraska and sent to Joseph Leidy at the Academy of Natural Sciences in Philadelphia, who named them ''Felis augustus'' in 1872. The fossils consisted of a premolar IV and maxilla fragment, the type (USNM 1004), as well as another tooth and a distal humerus, though the humerus is likely that of ''Panthera atrox'' or ''Smilodon fatalis''. Leidy also mistakenly believed the fossils were from the Pliocene, but they actually come from the Pleistocene. Later in 1919, O ...

American Lion
''Panthera atrox'', better known as the American lion, also called the North American lion, or American cave lion, is an extinct pantherine cat that lived in North America during the Pleistocene epoch and the early Holocene epoch, about 340,000 to 11,000 years ago. Its fossils have been excavated from Alaska to Mexico. Genetic analysis has shown that the American lion and the Late Pleistocene Eurasian cave lion (''Panthera spelaea'') are sister lineages. It was about 25% larger than the modern lion, making it one of the largest known felids. History and taxonomy Initial discovery and North American fossils The first specimen now assigned to ''Panthera atrox'' was collected in the 1830s and placed in the collection of by William Henry Huntingtion Esquire, who announced their discovery to the American Philosophical Society on April 1, 1836 and placed with other fossils from Huntington's collection in the Academy of Natural Sciences in Philadelphia. The specimen had been c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Panthera Onca Mesembrina Cave Painting
''Panthera'' is a genus within the family Felidae that was named and described by Lorenz Oken in 1816 who placed all the spotted cats in this group. Reginald Innes Pocock revised the classification of this genus in 1916 as comprising the tiger (''P. tigris''), lion (''P. leo''), jaguar (''P. onca''), and leopard (''P. pardus'') on the basis of common cranial features. Results of genetic analysis indicate that the snow leopard (formerly ''Uncia uncia'') also belongs to the genus ''Panthera'' (''P. uncia''), a classification that was accepted by IUCN Red List assessors in 2008. The tiger, lion, jaguar and leopard are the only cat species with anatomical structures that enable them to roar; the snow leopard cannot. The primary reason for this was formerly assumed to be the incomplete ossification of the hyoid bone. However, new studies show the ability to roar is due to other morphological features, especially of the larynx. Etymology The word ''panther'' derives from classical ...

Catonyx
''Catonyx'' is an extinct genus of ground sloth of the family Scelidotheriidae, endemic to South America during the Pliocene and Pleistocene epochs. It lived from 2.5 Ma to about 10,000 years ago, existing for approximately . The most recent date obtained is about 9600 B.P. Description This animal, like many other terrestrial sloths, was of conspicuous size and mighty build. It had to reach and exceed 4 meters in length, and the skull alone was at least 50 centimeters long. Its weight has been estimated at over 1500 kg. The snout of ''Catonyx'' was elongated, although not as in some similar forms (e.g., ''Scelidotherium''). Unlike the latter, ''Catonyx'' possessed shorter premaxillae that formed a triangular (and not rectangular like ''Scelidotherium'') snout tip, a pronounced rostrum bulge, a palate equipped with a median groove, and larger teeth. In addition, the mandibular symphysis was elongated and elevated, and the posterior lobe of the lower fourth molar was more curve ...
