Macrauchenia ("long llama", based on the now-invalid llama genus, Auchenia, from Greek "big neck") is an extinct genus of large ungulate native to South America from the Pliocene or Middle Pleistocene to the end of the Late Pleistocene. It was one of the last surviving members of the extinct order Litopterna, a group of South American native ungulates distinct from the two orders which contain all living ungulates which had been present in South America since the early Cenozoic, over 60 million years ago, prior to the arrival of living ungulates in South America around 2.5 million years ago as

Toxodon (from Ancient Greek τόξον (tóxon), meaning "bow", and ὀδούς (odoús), meaning "tooth", in reference to the curvature of the teeth) is an extinct genus of large ungulate native to South America from the Pliocene to the end of the Late Pleistocene. Toxodon is a member of Notoungulata, an order of extinct South American native ungulates distinct from the two living ungulate orders that had been indigenous to the continent for over 60 million years since the early Cenozoic, prior to the arrival of living ungulates into South America around 2.5 million years ago during the Great American Int

Arctotherium ("bear beast") is an extinct genus of short-faced bears endemic to Central and South America from the Late Pliocene to the end of the Late Pleistocene. Arctotherium migrated from North America to South America during the Great American Interchange, following the formation of the Isthmus of Panama during the late Pliocene.

Eremotherium (from Greek for "steppe" or "desert" "beast": ἔρημος "steppe or desert" and θηρίον "beast") is an extinct genus of giant ground sloth in the family Megatheriidae. Eremotherium lived in southern North America, Central America, and northern South America. It was one of the largest sloths, with a body size comparable to elephants, weighing around and measuring about long, slightly larger than its close relative Megatherium.

Hippidion (meaning "little horse" in Ancient Greek) is an extinct genus of equine that lived in South America from the Late Pliocene to the end of the Late Pleistocene (Lujanian), between 2.5 million and 11,000 years ago. Hippidion arrived in South America along with many other animals of North American origin as part of the Great American Interchange. They were one of two lineages of equines native to South America during the Pleistocene epoch, alongside Equus (Amerhippus) neogeus. Hippidion ranged widely over South America, extending to the far south of Patagonia. Hippidion differs from livi

Cuvieronius is an extinct New World genus of gomphothere which ranged from southern North America to northwestern South America during the Pleistocene epoch. Reaching a shoulder height of and a body mass of , it was comparable in size to an Asian elephant. Cuvieronius inhabited subtropical and tropical latitudes in environments ranging from grasslands to tropical rainforest. Among the last gomphotheres along with the South American Notiomastodon, it became extinct as part of the end Pleistocene-extinction event, approximately 12-11,000 years ago, along with most other large mammals in the Amer

Platygonus ("flat head" in reference to the straight shape of the forehead) is an extinct genus of herbivorous peccaries of the family Tayassuidae, endemic to North and South America from the Miocene through Pleistocene epochs (10.3 million to 11,000 years ago), existing for about . P. compressus stood tall.

Glossotherium is an extinct genus of large mylodontid ground sloths of the subfamily Mylodontinae. It represents one of the best-known members of the family, along with Mylodon and Paramylodon. Reconstructed animals were between long and possibly weighed up to 1,002.6–1,500 kg. The majority of finds of Glossotherium date from the Middle and Upper Pleistocene, around 300,000 to 10,000 years ago, with a few dating older, as far back Pliocene, about 3.3-3 million years ago. The range included large parts of South America, east of the Andes roughly from latitude 20 to 40 degrees south, leavin

Scelidotherium is an extinct genus of ground sloth of the family Scelidotheriidae, endemic to South America during the Late Pleistocene epoch. It lived from 780,000 to 11,000 years ago, existing for approximately .

Protocyon (from Greek for "first dog") is an extinct genus of large canid endemic to South and Central America from the Late Pliocene to the Late Pleistocene.

Mixotoxodon ("mixture Toxodon") is an extinct genus of notoungulate of the family Toxodontidae inhabiting South America, Central America and parts of southern North America during the Pleistocene epoch, from 1,800,000–12,000 years ago.

Panochthus is an extinct genus of glyptodont, which lived in the Gran Chaco-Pampean region of Argentina (Lujan, Yupoí and Agua Blanca Formations), Brazil (Jandaíra Formation), Bolivia (Tarija and Ñuapua Formations), Paraguay and Uruguay (Sopas and Dolores Formations) during the Pleistocene epoch. The first specimen of Panochthus consisted of two carapace (shell) fragments, now lost, recovered from Buenos Aires. In 1845, the fragments were referred by Sir Richard Owen to the genus Glyptodon. In 1864, working from more complete remains, Karl Hermann Konrad Burmeister erected Panochthus as a subg

Hemiauchenia is an extinct genus of lamine camelids that evolved in North America in the Miocene epoch about 10 million years ago. This genus diversified and entered South America in the Late Pliocene about three to two million years ago, as part of the Great American Biotic Interchange. The genus became extinct at the end of the Pleistocene. The monophyly of the genus has been considered questionable, with phylogenetic analyses finding the genus to paraphyletic or polyphyletic, with some species suggested to be more closely related to living lamines (llamas and relatives) than to other Hemiau

Lestodon is an extinct genus of giant ground sloth native to South America during the Pleistocene epoch. Its fossil remains have primarily been found in the Pampas and adjacent regions. The largest member of the family Mylodontidae, It is estimated to have weighed . It was a herbivore and primarily fed on the grasses and low-growing plants.

Catonyx is an extinct genus of ground sloth of the family Scelidotheriidae, endemic to South America during the Pliocene and Pleistocene epochs. It lived from 2.5 Ma to about 10,000 years ago, existing for approximately . The most recent date obtained is about 9600 B.P.

Theriodictis is an extinct monotypic genus of cerdocyonine canid endemic to South America during the Middle Pleistocene.

Morenelaphus is an extinct genus of capreoline deer that lived in South America during the Pleistocene, ranging from the Pampas to southern Bolivia and Northeast Brazil. There is only a single recognised species, Morenelaphus brachyceros. It was a large deer, with some specimens estimated to exceed 200 kilograms in body mass. The antlers were over 70 cm in length, and are superficially similar those of deer belonging to the subfamily Cervinae, like red deer. Fossils of the genus have been recovered from the Agua Blanca, Fortín Tres Pozos and Luján Formations of Argentina, the Ñuapua Formation

Plaxhaplous was a dubious genus of glyptodont, an extinct relative of the modern armadillo. It lived in the Pleistocene epoch. The type species is Plaxhaplous canaliculatus. Plaxhaplous canaliculatus fossils were found in Argentina, near Luján in Buenos Aires Province. Plaxhaplous fossils have also been found in Uruguay. and in the Charana Formation of Bolivia.

Reigomys primigenus is an extinct oryzomyine rodent known from Pleistocene deposits in Tarija Department, southeastern Bolivia. It is known from a number of isolated jaws and molars which show that its molars were almost identical to those of the living Lundomys. On the other hand, the animal possesses a number of derived traits of the palate which document a closer relationship to living Holochilus, the genus of South American marsh rats, and for this reason it was placed in the genus Holochilus when it was first described in 1996. The subsequent discoveries of Noronhomys and Carletonomys, wh

Nothrotherium is an extinct genus of medium-sized ground sloth from South America (Bolivia, Brazil and the Ware Formation, La Guajira, Colombia). It differs from Nothrotheriops in smaller size and differences in skull and hind leg bones.
