Glyptodon (; ) is a genus of glyptodont, an extinct group of large, herbivorous armadillos that lived from the Pliocene, around 3.2 million years ago, to the early Holocene, around 11,000 years ago, in South America. It is one of, if not the, best-known genera of glyptodont. Glyptodon has a long and storied past, being the first named extinct cingulate and the type genus of the subfamily Glyptodontinae. Fossils of Glyptodon have been recorded as early as 1814 from Pleistocene aged deposits from Uruguay, though many were incorrectly referred to the ground sloth Megatherium by early paleontologi

Doedicurus, from Ancient Greek δοῖδυξ (doîdux), meaning "pestle" and oυρά (ourá), meaning "tail", is an extinct genus of glyptodont from South America containing one species, D. clavicaudatus. Glyptodonts are a member of the family Chlamyphoridae, which also includes some modern armadillo species, and they are classified in the superorder Xenarthra alongside sloths and anteaters. Being a glyptodont, it was a rotund animal with heavy armor and a carapace. Averaging at an approximate , it was one of the largest glyptodonts to have ever lived. Though glyptodonts were quadrupeds, large ones like D

Josephoartigasia is an extinct genus of enormous dinomyid rodent from the Early Pliocene to Early Pleistocene of Uruguay. Its closest living relative is the pacarana. Josephoartigasia is named after Uruguayan national hero José Artigas. It contains two species: J. magna, described in 1966 based on a left mandible, and J. monesi, described in 2008 based on a nearly complete skull. Both are reported from the San José Member of the Raigón Formation by the Barrancas de San Gregorio along Kiyú beach.

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

Psilopterus (Greek for "bare wing") is an extinct genus of phorusrhacid ("terror bird") from the Middle Oligocene to possibly the Late Pleistocene of Argentina and Uruguay. Compared to other phorusrhacids, members of the genus are both relatively gracile and diminutive, and include the smallest known species of terror bird: with the head raised P. bachmanni was in height and weighed about , while the largest members of the genus were only about . The birds resemble the modern cariama (Cariama cristata), except with a heavier build and considerably smaller wings. Fossil finds in Uruguay indicat

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.

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.

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

Antifer is an extinct genus of large herbivorous deer belonging to the tribe Odocoileini native to South America during the Pleistocene, becoming extinct around 12,000 years ago. It was one of the largest South American deer genera, with an estimated body mass of up to , comparable to red deer, considerably exceeding the marsh deer, the largest living South American deer species in size. The genus has large antlers that could reach a length of over .

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

Neolicaphrium is an extinct genus of ungulate mammal belonging to the extinct order Litopterna. This animal lived from the Late Pliocene (Chapadmalalan) to the Late Pleistocene (Lujanian) in southern South America, being the last survivor of the family Proterotheriidae.

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.
