South America (orthographic Projection)
South America is a continent entirely in the Western Hemisphere and mostly in the Southern Hemisphere, with a relatively small portion in the Northern Hemisphere at the northern tip of the continent. It can also be described as the southern subregion of a single continent called America. South America is bordered on the west by the Pacific Ocean and on the north and east by the Atlantic Ocean; North America and the Caribbean Sea lie to the northwest. The continent generally includes twelve sovereign states: Argentina, Bolivia, Brazil, Chile, Colombia, Ecuador, Guyana, Paraguay, Peru, Suriname, Uruguay, and Venezuela; two dependent territories: the Falkland Islands and South Georgia and the South Sandwich Islands; and one internal territory: French Guiana. In addition, the ABC islands of the Kingdom of the Netherlands, Ascension Island (dependency of Saint Helena, Ascension and Tristan da Cunha, a British Overseas Territory), Bouvet Island ( dependency of Norway ...

Lestodon Armatus Ghedo
''Lestodon'' is an extinct genus of megafaunal ground sloth from South America during the Pliocene to Pleistocene periods. Its fossil remains have been found in Argentina, Paraguay, Uruguay, Venezuela, Bolivia, and Brazil. Measuring approximately from snout to tail tip, it is estimated to have weighed . It was a herbivore and primarily fed on the grasses on the South American plains and is thought to perhaps have used its semi-bipedal stance to obtain foliage from trees. ''Lestodon'' is placed as member of the Mylodontidae as indicated by the lobed form of the last tooth in the dentition. Etymology The genus name ''Lestodon'' derives from the Greek for "robber tooth". Evolutionary adaptations Cranial The skeleton morphologically reflects its evolutionary history as well as its daily activities. At the caudal end, the sloth’s head connects to its neck with a class one lever. The skull is two to three orders of magnitude larger than that of living species of sloth, but ...

Canis Dirus Reconstruction
''Canis'' is a genus of the Caninae which includes multiple extant species, such as wolves, dogs, coyotes, and golden jackals. Species of this genus are distinguished by their moderate to large size, their massive, well-developed skulls and dentition, long legs, and comparatively short ears and tails.Heptner, V. G.; Naumov, N. P. (1998). ''Mammals of the Soviet Union'' Vol.II Part 1a, SIRENIA AND CARNIVORA (Sea Cows, Wolves and Bears). Science Publishers, Inc. USA. pp. 124–129. . Taxonomy The genus ''Canis'' (Carl Linnaeus, 1758) was published in the 10th edition of Systema Naturae and included the dog-like carnivores: the domestic dog, wolves, coyotes and jackals. All species within ''Canis'' are phylogenetically closely related with 78 chromosomes and can potentially interbreed. In 1926, the International Commission on Zoological Nomenclature (ICZN) in Opinion 91 included Genus ''Canis'' on its ''Official Lists and Indexes of Names in Zoology''. In 1955, the ICZN's Direction ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dire Wolf
The dire wolf (''Aenocyon dirus'' ) is an extinct canine. It is one of the most famous prehistoric carnivores in North America, along with its extinct competitor ''Smilodon''. The dire wolf lived in the Americas and eastern Asia during the Late Pleistocene and Early Holocene epochs (125,000–9,500 years ago). The species was named in 1858, four years after the first specimen had been found. Two subspecies are recognized: ''Aenocyon dirus guildayi'' and ''Aenocyon dirus dirus''. The largest collection of its fossils has been obtained from the Rancho La Brea Tar Pits in Los Angeles. Dire wolf remains have been found across a broad range of habitats including the plains, grasslands, and some forested mountain areas of North America, the arid savanna of South America, and the steppes of eastern Asia. The sites range in elevation from sea level to . Dire wolf fossils have rarely been found north of 42°N latitude; there have been only five unconfirmed reports above this latitude. ...

Pampatherium
''Pampatherium'' is an extinct genus of xenarthran that lived in the Americas during the Pleistocene. Some species went extinct right at the Pleistocene-Holocene border. Distribution ''Pampatherium humboldtii'' and ''P. typum'' lived in South America (mostly Brazil) during the Pleistocene, with ''P. humboldtii'' surviving into the very Late Pleistocene. ''Pampatherium mexicanum'' was the only North American species, reaching as far north as Sonora, Mexico. It lived during the Rancholabrean. Description ''Pampatherium'' resembled a very large armadillo. One species, ''P. humboldtii'', weighed up to . Pampatheres generally resembled armadillos, particularly in the shape of it skull, long snout, and the presence of three areas on the carapace (movable bands, scapular and pelvic shields). Among the features that distinguish them from armadillos are their posterior teeth, which are bilobate rather than peg-like. Their endocranial morphology is also similar to glyptodonts.

Pachyarmatherium
''Pachyarmatherium'' is a genus of extinct large armadillo-like cingulates found in North and South America from the Pliocene and Pleistocene epochs, related to the extant armadillos and the extinct pampatheres and glyptodonts. It was present from 4.9 Mya to 11,000 years ago, existing for approximately . Taxonomy ''Pachyarmatherium'' was named by Downing and White (1995). Its type is ''P. leiseyi''. It was assigned to Dasypodoidea by Downing and White (1995), and tentatively to Glyptodontidae by McKenna and Bell (1997). A cladistic analysis performed by de O. Porpino et al. (2009) led to the conclusion that ''Pachyarmatherium'' is a sister group to a clade consisting of Glyptodontidae and Pampatheriidae. Oliveira et al. (2013) suggest that ''Pachyarmatherium'' is a possible dasypodid. Fossil distribution of ''Pachyarmatherium'' ''P. leiseyi'' * Kissimmee River site, Tamiami Formation, Okeechobee County, Florida ~4.9—1.8 Mya. * Haile 16A Site, Alachua Count ...
