Species

Aeretes is a genus of squirrels that contains a single extant species, the groove-toothed flying squirrel (Aeretes melanopterus).

Two fossil species are also known from Late Pliocene of China. [1]

The earliest fossil record of Aeretes was found in South China in Middle Pleistocene deposits. In the Beijing area, the earliest records are from Upper Cave and Tianyuan Cave at Zhoukoudian. These fossils are of the Late Pleistocene age. The geographical distribution of this species are very limited. Aeretes experience evolution through the increase and decrease of tooth size throughout time. [2]

<i>Homotherium</i> Extinct genus of carnivores

Homotherium is an extinct genus of scimitar-toothed cat belonging to the extinct subfamily Machairodontinae that inhabited North America, Eurasia, and Africa during the Pliocene and Pleistocene epochs from around 4 million to 12,000 years ago. It was one of the last surviving members of the subfamily alongside the more famous sabertooth Smilodon, to which it was not particularly closely related. It was a large cat, comparable in size to a lion, functioning as an apex predator in the ecosystems it inhabited. In comparison to Smilodon, the canines of Homotherium were shorter, and it is suggested to have had a different ecology from Smilodon as a pursuit predator adapted to running down large prey in open habitats, with Homotherium also proposed to have likely engaged in cooperative hunting.

Peking Man is a subspecies of H. erectus which inhabited what is now northern China during the Middle Pleistocene. Its fossils have been found in a cave some 47 km (29 mi) southwest of Beijing, known as the Zhoukoudian Peking Man Site. The first fossil, a tooth, was discovered in 1921, and Zhoukoudian has since become the most productive H. erectus site in the world. Peking Man was instrumental in the foundation of Chinese anthropology, and fostered an important dialogue between Western and Eastern science. Peking Man became the centre of anthropological discussion, and was classified as a direct human ancestor, propping up the Out of Asia theory that humans evolved in Asia.

Paleoanthropology or paleo-anthropology is a branch of paleontology and anthropology which seeks to understand the early development of anatomically modern humans, a process known as hominization, through the reconstruction of evolutionary kinship lines within the family Hominidae, working from biological evidence and cultural evidence.

Zhoukoudian Peking Man Site (周口店北京人遗址), also romanized as Choukoutien, is a cave system in suburban Fangshan District, Beijing. It has yielded many archaeological discoveries, including one of the first specimens of Homo erectus, dubbed Peking Man, and a fine assemblage of bones of the giant short-faced hyena Pachycrocuta brevirostris.

<i>Stegodon</i> Genus of extinct proboscidean

Stegodon is an extinct genus of proboscidean, related to elephants. It was originally assigned to the family Elephantidae along with modern elephants but is now placed in the extinct family Stegodontidae. Like elephants, Stegodon had teeth with plate-like lophs that are different from those of more primitive proboscideans like gomphotheres and mammutids. Fossils of the genus are known from Africa and across much of Asia, as far southeast as Timor. The oldest fossils of the genus are found in Late Miocene strata in Asia, likely originating from the more archaic Stegolophodon, subsequently migrating into Africa. While the genus became extinct in Africa during the Pliocene, Stegodon persisted in South, Southeast and Eastern Asia into the Late Pleistocene.

<i>Pachycrocuta</i> Genus of mammals (fossil)

Pachycrocuta is an extinct genus of prehistoric hyenas. The largest and most well-researched species is Pachycrocuta brevirostris, colloquially known as the giant short-faced hyena as it stood about 90–100 cm (35–39 in) at the shoulder and it is estimated to have averaged 110 kg (240 lb) in weight, approaching the size of a lioness, making it the largest known hyena. Pachycrocuta first appeared during the late Miocene. By 800,000 years ago, it became locally extinct in Europe, with it surviving in East Asia until at least 500,000 years ago, and possibly later elsewhere in Asia.

<i>Eucladoceros</i> Extinct genus of mammal

Eucladoceros is an extinct genus of large deer whose fossils have been discovered across Eurasia, from Europe to China, spanning from the Late Pliocene-Early Pleistocene. It is noted for its unusual comb-like or branching antlers.

The groove-toothed flying squirrel or North Chinese flying squirrel is a species of rodent in the family Sciuridae. It is considered monotypic within the genus Aeretes. It is endemic to China, and occurs in Sichuan, Gansu, Hebei, and Beijing. Its natural habitat is temperate forests.

Paleontology or palaeontology is the study of prehistoric life forms on Earth through the examination of plant and animal fossils. This includes the study of body fossils, tracks (ichnites), burrows, cast-off parts, fossilised feces (coprolites), palynomorphs and chemical residues. Because humans have encountered fossils for millennia, paleontology has a long history both before and after becoming formalized as a science. This article records significant discoveries and events related to paleontology that occurred or were published in the year 1982.

<span class="mw-page-title-main">Giant tapir</span> Extinct species of mammal

The giant tapir is an extinct species of tapir that lived in southern China, Vietnam and Laos, with reports suggesting it also lived in Taiwan, Java, and potentially Borneo. The species has been recorded from Middle and Late Pleistocene. There is only weak evidence for a Holocene survival. Tapirus augustus was larger than any living tapir, with an estimated weight of about 623 kilograms (1,373 lb). The species was also placed in its own genus of Megatapirus, however, it is now conventionally placed within Tapirus.

<i>Stephanorhinus</i> Extinct genus of rhinoceros

Stephanorhinus is an extinct genus of two-horned rhinoceros native to Eurasia and North Africa that lived during the Late Pliocene to Late Pleistocene. Species of Stephanorhinus were the predominant and often only species of rhinoceros in much of temperate Eurasia, especially Europe, for most of the Pleistocene. The last two species of Stephanorhinus – Merck's rhinoceros and the narrow-nosed rhinoceros – went extinct during the last glacial period.

Miniopterus tao is a fossil bat in the genus Miniopterus from the Pleistocene of Zhoukoudian in China. It is known from a number of mandibles, which were initially identified as the living species Miniopterus schreibersii in 1963 before being recognized as a separate species, M. tao, in 1986. Miniopterus tao is larger than living M. schreibersii and has more closely spaced lower premolars and more robust talonids on the lower molars. The back part of the mandible is relatively low and on it, the coronoid and condyloid processes are about equally high. The average length of the mandible is 12.0 mm.

<span class="mw-page-title-main">Narrow-nosed rhinoceros</span> Extinct species of rhinoceros

The narrow-nosed rhinoceros, also known as the steppe rhinoceros is an extinct species of rhinoceros belonging to the genus Stephanorhinus that lived in western Eurasia, including Europe, as well as North Africa during the Pleistocene. It first appeared in Europe around 500,000 years ago during the Middle Pleistocene and survived there until at least 34,000 years Before Present. It was native to temperate and Mediterranean environments, where it fed on low growing plants and to a lesser extent woody plants. Evidence has been found that it was exploited for food by archaic humans, including Neanderthals.

<i>Canis mosbachensis</i> Extinct species of carnivore

Canis mosbachensis is an extinct wolf that inhabited Europe from the late Early Pleistocene to the Middle Pleistocene, around 1.4 million to 400,000 years ago. Canis mosbachensis is widely considered to have descended from the earlier Canis etruscus, and to be the ancestor of the living grey wolf with some considering it as a subspecies of the wolf as Canis lupus mosbachensis. The morphological distinction between C. mosbachensis and C. lupus has historically been vague, and attribution of fossils to C. mosbachensis or to C. lupus around the transition time between the two species is ambiguous.
