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)
Guanacos are one of the largest terrestrial mammals native to South America today. [6] Other terrestrial mammalian megafauna weighing as much or more than the guanaco include the tapirs , the marsh deer , the white-tailed deer , the spectacled bear , and the jaguar .
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 ]
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 ...
The Baird's tapir (Tapirus bairdii), also known as the Central American tapir, is a species of tapir native to Mexico, Central America, and northwestern South America. [4] It is the largest of the three species of tapir native to the Americas, as well as the largest native land mammal in both Central and South America.
The South American cougar (Puma concolor concolor), also known as the Andean mountain lion [4] or puma, [5] is a cougar subspecies occurring in northern and western South America, from Colombia and Venezuela to Peru, Bolivia, Argentina and Chile. [6] It is the nominate subspecies.
Sudamerica, literally "South America" in Spanish, is a genus of mammal from the extinct suborder Gondwanatheria that lived in Patagonia, Argentina (Salamanca Formation) and Antarctica (La Meseta Formation) from the Middle Paleocene , just after the end of the "Age of Dinosaurs", to the Early Eocene (Casamayoran).
Thylacosmilus is an extinct genus of saber-toothed metatherian mammals that inhabited South America from the Late Miocene to Pliocene epochs.Though Thylacosmilus looks similar to the "saber-toothed cats", it was not a felid, like the well-known North American Smilodon, but a sparassodont, a group closely related to marsupials, and only superficially resembled other saber-toothed mammals due to ...
