Mylodon Darwinii
''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 Natural Monument, 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 integument, integumentary structures are preserved. The diet of ''Mylodon'' is known in great detail due to fossilized coprolite, faeces. Its skull is greatly elongated ...

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 ...

Charles Darwin
Charles Robert Darwin ( ; 12 February 1809 – 19 April 1882) was an English naturalist, geologist, and biologist, widely known for his contributions to evolutionary biology. His proposition that all species of life have descended from a common ancestor is now generally accepted and considered a fundamental concept in science. In a joint publication with Alfred Russel Wallace, he introduced his scientific theory that this branching pattern of evolution resulted from a process he called natural selection, in which the struggle for existence has a similar effect to the artificial selection involved in selective breeding. Darwin has been described as one of the most influential figures in human history and was honoured by burial in Westminster Abbey. Darwin's early interest in nature led him to neglect his medical education at the University of Edinburgh; instead, he helped to investigate marine invertebrates. His studies at the University of Cambridge's Christ's Col ...

Paramylodon
''Paramylodon'' is an extinct genus of ground sloth of the family Mylodontidae endemic to North America during the Pliocene through Pleistocene epochs, living from around ~4.9 Mya–11,000 years ago. It is also known as Harlan's ground sloth. Due to the partly very good fossil preservation, the body armor typical for the mylodonts has mostly been preserved in the form of osteoderms. In addition, a sex-specific difference in cranial structure can be demonstrated. According to the finds, the representatives of ''Paramylodon'' lived in open landscapes, sometimes also in mountainous locations, and most likely fed on grass-eating or mixed plant diets. Unique trace fossils also provide information about the locomotion of the animals, which was quadrupedal. In addition, due to the design of the forelimbs, a certain burrowing way of life cannot be disputed. Within the genus only two species are recognized: ''Paramylodon harlani'' and ''Paramylodon garbanii''. The first fossil findings d ...
