The armadillos are small mammals with a bony armored shell. All 21 extant species are found in South America, where they originated. Their much larger relatives, the pampatheres and glyptodonts, once lived in North and South America but became extinct following the appearance of humans. Family: Dasypodidae (long-nosed armadillos) Subfamily ...
The extinct meridiungulate family Archaeohyracidae, consisting of seven genera of notoungulate mammals known from the Paleocene through the Oligocene of South America, [36] is a group unrelated to the true hyraxes.
The South American tapir can be found near water in the Amazon Rainforest and River Basin in South America, east of the Andes. Its geographic range stretches from Venezuela, Colombia, and the Guianas in the north to Brazil, Argentina, and Paraguay in the south, to Bolivia, Peru, and Ecuador in the west. [15]
Capybaras are semiaquatic mammals [15] found throughout all countries of South America except Chile. [19] They live in densely forested areas near bodies of water, such as lakes, rivers, swamps, ponds, and marshes, [14] as well as flooded savannah and along rivers in the tropical rainforest. They are superb swimmers and can hold their breath ...
South America had no placental predatory mammals until the Pleistocene, and xenarthran large-mammal faunas may have been vulnerable to many factors including a rise in numbers of mammalian predators, resource use by spreading North American herbivores with faster metabolisms and higher food requirements, and climate change.
The fauna of South America consists of a huge variety of unique animals some of which evolved in relative isolation. The isolation of South America allowed for many separate animal lineages to evolve, creating a lot of originality when it comes to South American animal species. [ 1 ]
Armadillos are small mammals with a bony armored shell. There are 21 extant species in the Americas, 19 of which are only found in South America, where they originated. Their much larger relatives, the pampatheres and glyptodonts, once lived in North and South America but became extinct following the appearance of humans.
South America was an island continent for much of the Cenozoic, or the "Age of Mammals". As a result, its mammals evolved in their own unique directions, as Australia and Madagascar still have today.
