Australopithecus (, ; or , , ) is a genus of early hominins that existed in Africa during the Pliocene and Early Pleistocene. The genera Homo (which includes modern humans), Paranthropus, and Kenyanthropus evolved from some Australopithecus species. Australopithecus is a member of the subtribe Australopithecina, which sometimes also includes Ardipithecus, though the term "australopithecine" is sometimes used to refer only to members of Australopithecus. Species include A. garhi, A. africanus, A. sediba, A. afarensis, A. anamensis, A. bahrelghazali, and A. deyiremeda. Debate exists as to whethe

Megatherium ( ; from Greek () 'great' + () 'beast') is an extinct genus of large ground sloths endemic to South America that lived from the Early Pliocene through the end of the Late Pleistocene. It is best known for the elephant-sized, type species Megatherium americanum, primarily known from the Pampas, but ranging southwards to northernmost Patagonia and northwards to southern Bolivia during the late Middle Pleistocene and Late Pleistocene. Various other species have been described, including those belonging to the Andean subgenus Pseudomegatherium, which range in size from comparable to M.

Elasmotherium (from Ancient Greek ἔλασμα (élasma), meaning "metal plate" with the intended meaning "lamina" in reference to the tooth enamel, and θηρίον (theríon), meaning "beast") is an extinct genus of very large rhinoceros that lived in Eastern Europe, Central Asia and East Asia from the late Miocene through to the Late Pleistocene, until at least 39,000 years ago. It was the last surviving member of the subfamily Elasmotheriinae, a formerly diverse group of rhinoceroses separate from the subfamily Rhinocerotinae, that contains all living rhinoceroses.

Miracinonyx, colloquially known as the American cheetah or the New World cheetah, is an extinct genus of felids belonging to the subfamily Felinae that was endemic to North America from the Pleistocene epoch (about 2.5 million to 16,000 years ago) and morphologically similar to the modern cheetah (Acinonyx jubatus), although its apparent similar ecological niches have been considered questionable due to anatomical morphologies of the former that would have limited its ability to act as a specialized pursuit predator. The genus was originally known from fragments of skeletons, but nearly comple

Camelops is an extinct genus of camel that lived in North and Central America from the middle Pliocene (from around 4-3.2 million years ago) to the end of the Pleistocene (around 13-12,000 years ago). It is more closely related to living camels than to lamines (llamas, alpacas, vicuñas, and guanacos), making it a true camel of the Camelini tribe. Its name is derived from the Ancient Greek (, "camel") and (, "face"), i.e. "camel-face". Camelops lived across Western North America, ranging from the Pacific Coast to the Great Plains, southwards to Honduras and northwards to Alaska. Camelops became

Castoroides (from Latin castor (beaver) and -oides (like)), or the giant beaver, is an extinct genus of enormous, bear-sized beavers that lived in North America during the Pleistocene. Two species are currently recognized, C. dilophidus in the Southeastern United States and C. ohioensis in most of North America. C. leiseyorum was previously described from the Irvingtonian age but is now regarded as an invalid name. All specimens previously described as C. leiseyorum are considered to belong to C. dilophidus.

Metridiochoerus is an extinct genus of swine known from the Pliocene and Pleistocene of Africa. It is also known as the giant warthog.

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

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 .

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.
