The genus Hydrochoerus contains two living (the lesser and greater capybaras) and three extinct species of rodents from South America, the Caribbean island of Grenada, California and Panama. Capybaras are the largest living rodents. The name of the genus is derived from Ancient Greek ὕδωρ (húdor), meaning "water", and χοῖρος (khoîros), meaning "pig".

Purussaurus is a genus of extinct giant caimans that lived in the Americas during the Miocene epoch, from the Friasian to the Huayquerian in the SALMA classification. It is known from skull material found in the Brazilian and Peruvian Amazon, Argentina, Colombian Villavieja Formation, Panamanian Culebra Formation, Urumaco, and Socorro Formations of northern Venezuela.

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.

Chapalmalania is an extinct genus of procyonid from the Late Miocene or Early Pliocene to Early Pleistocene (Montehermosan to Uquian) of Argentina (Andalhualá Formation), Venezuela (San Gregorio Formation, Venezuela), and Colombia (Ware Formation, Cocinetas Basin, La Guajira).

Gryposuchus (meaning "hooked crocodile") is an extinct genus of gavialid crocodilian. Fossils have been found from Argentina, Colombia, Venezuela, Brazil and the Peruvian Amazon. The genus existed during the Miocene epoch (Colhuehuapian to Huayquerian). One recently described species, G. croizati, grew to an estimated length of . Gryposuchus is the type genus of the subfamily Gryposuchinae, although a 2018 study indicates that Gryposuchinae and Gryposuchus might be paraphyletic and rather an evolutionary grade towards the gharial.

Theosodon is an extinct genus of litoptern mammal from the Early to Middle Miocene of South America.

Granastrapotherium is an extinct genus of ungulate mammals, described from remains found in rocks of the Honda Group in the Tatacoa Desert, in the Colombian departments of Huila and Tolima, at the Miocene fossil site La Venta. The only species formally recognized is Granastrapotherium snorki (from Spanish, gran, "great"; Astrapotherium, "lightning beast"; and snorkel, breathing tube, in reference to the trunk). Remains found in Bolivia and Peru, seem to belong to Granastrapotherium or a very similar animal.

Anachlysictis gracilis is an extinct carnivorous mammal belonging to the group Sparassodonta, which were metatherians (a group including marsupials and their close relatives) that inhabited South America during the Cenozoic. Anachlysictis is the first record of such borhyaenoids in northern South America, and also the most primitive known member of the family Thylacosmilidae, a group of predators equipped with "saber teeth". It was also the only confirmed record of a thylacosmilid that did not belong to the genus Thylacosmilus until the official publication of Patagosmilus in 2010.

Mourasuchus is an extinct genus of giant, aberrant caiman from the Miocene of South America. Its skull has been described as duck-like, being broad, flat, and very elongate, superficially resembling Stomatosuchus from the Late Cretaceous.

Lycopsis is an extinct genus of South American metatherian that lived during the Miocene in Argentina and Colombia.

Pholadomya is a genus of saltwater clams, marine bivalve molluscs in the family Pholadomyidae.

Langstonia (meaning "[crocodile] of Langston", in honor of paleontologist Wann Langston, Jr.) is an extinct genus of notosuchian crocodylomorph of the family Sebecidae. It lived in the middle Miocene (specifically in the Laventan land-mammal age), in the "Monkey Beds" of the Colombian Villavieja Formation. Langstonia was named in 2007 by Alfredo Paolillo and Omar Linares for fossils originally described by Langston in 1965 as Sebecus huilensis. Thus, the type species is L. huilensis. == Discovery and naming == left|thumb|The Tatacoa Desert, in which has been discovered numerous Miocene fossil

Neotamandua is an extinct genus of anteaters that lived in the Miocene to Pliocene in South America.

Huilatherium is an extinct genus of leontiniid, a group of hoofed mammals belonging to the order Notoungulata, that comprises other South American ungulate families that evolved in parallel with some mammals of the Northern hemisphere. The leontiinids were a family of herbivorous species comprising medium to large browsers, with relatively short skulls and robust limbs, somewhat similar to their relatives, the best known toxodontids.

Dukecynus is an extinct genus of meat-eating metatherian belonging to the order Sparassodonta, which lived in South America during the Middle Miocene (Laventan), between about 13.8 and 11.8 million years ago. The name of the genus meaning "Duke dog", for Duke University and the Greek word cynos, dog, for the pretended similarity of this animal with dogs. A single species known so far, Dukecynus magnus. The species name "magnus" derives from Latin for big, to reflect their great size.

Artwork by Edwin Chávez "Disfrasaurio". Xenastrapotherium is an extinct genus of astrapothere, a type of hoofed herbivorous mammal, native to South America, which lived in the Middle to Late Miocene period, typically during the Laventan stage. It is a member of the family Astrapotheriidae in the subfamily Uruguaytheriinae, large astrapotheres, equipped with a trunk-like nose and protruding teeth, s

Scirrotherium is an extinct genus of pampatheres, a family of herbivorous cingulates, related to the similar but smaller modern armadillos, and with the now extinct glyptodonts, well-known from their shell-like armor. Its scientific name is derived from the Greek prefix "skiros-", "cover", and the suffix "-therion, "beast", while the name of the type species, hondaensis, honors the town of Honda, in the Tolima Department of Colombia. Scirrotherium is one of several genera of xenarthrans found in the La Venta fauna, dated from the Middle Miocene.

Potamosiren is an extinct genus of manatee from the Middle Miocene (Laventan) Honda Group of Colombia.

Created by Edwin Chávez "Disfrasaurio". Boreostemma is an extinct genus of glyptodonts from northern South America. Fossils assigned to the genus were first described as belonging to Asterostemma from southern South America, but have been placed in the new genus Boreostemma by Carlini et al. in 2008. The type species is B. pliocena. Fossils of Boreostemma have been found in the Honda Group of Colombia, in Peru an

Eocaiman is an extinct genus of caiman containing species living from the Early Paleocene to Miocene in what is now Argentina (Salamanca and Sarmiento Formations), Itaboraí Formation of Brazil and Colombia (Honda Group). Eocaiman contains three described species: E. cavernensis, E. palaeocenicus, and E. itaboraiensis, and is typically recovered as one of the more basal members of Caimaninae. Notocaiman was synonymized with Eocaiman paleocenicus in 2022.

Charactosuchus is an extinct genus of crocodilian. It was assigned to the family Crocodylidae in 1988. Specimens have been found in Colombia, Brazil, Jamaica, and possibly Florida and South Carolina. It was gharial-like in appearance with its long narrow snout but bore no relation to them, being more closely related to modern crocodiles than to gharials.

Cebupithecia is an extinct genus of New World monkeys from the Middle Miocene (Laventan in the South American land mammal ages; 13.8 to 11.8 million years ago). Its remains have been found at the Konzentrat-Lagerstätte of La Venta in the Honda Group of Colombia. The type species is C. sarmientoi.

Hondadelphys is an extinct genus of carnivorous sparassodonts, known from the Middle Miocene of Colombia. The type species, H. fieldsi, was described in 1976 from the fossil locality of La Venta, which hosts fossils from the Villavieja Formation. Hondadelphys was originally interpreted as belonging to the opossum family Didelphidae, but subsequently assigned to its own family, Hondadelphidae and interpreted as a basal sparassodont. The genus name refers to the Honda Group, the stratigraphic group in which the fossils of this animal were first found, combined with delphys (Greek for "womb", a c

Miocochilius is an extinct genus of small notoungulate mammals (typotheres) native to South America. The genus lived during the Middle Miocene epoch (Laventan in the SALMA classification). The genus contains two described species, the type species M. anomopodus described in 1953 by Ruben Arthur Stirton and M. federicoi, described and included in the genus by Darin A. Croft.
