South America's considerable cervid diversity belies their relatively recent arrival. The presence of camelids in South America but not North America today is ironic, given that they have a 45-million-year-long history in the latter continent (where they originated), and only a 3-million-year history in the former. Family: Tayassuidae (peccaries)
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 ]
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 ...
In 2024, the South American tapir was observed in the state of Rio de Janeiro for the first time since 1914. According to Marcelo Cupello, a scientist from Rio de Jaineiro's State Environmental Institution, the return of the species indicates that the state's forests are once again capable of sustaining populations of large mammals.

Meridiungulata might have originated in South America from a North American condylarth ancestor, [3] and they may be members of the clade Laurasiatheria, related to other ungulates, including artiodactyls and perissodactyls. [4] It has, however, been suggested the Meridiungulata are part of a different macro-group of placental mammals called ...
Around the middle of the Cenozoic, approximately 34 million years ago, [3] two types of mammals appeared for the first time in South America: rodents and primates. Both of these groups had already been inhabiting other continents for millions of years and they simply arrived in South America rather than originated there.
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.
