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]
Homotherium is an extinct genus of machairodontine scimitar-toothed cat that inhabited North America, South America, Eurasia, and Africa during the Pliocene and Pleistocene epochs from around 4 million to 12,000 years ago. In comparison to Smilodon, the canines of Homotherium were shorter, and it was probably adapted to running down rather than ambushing prey.
Peking Man is a subspecies of H. erectus which inhabited the Zhoukoudian cave site in modern northern China during the Chibanian. The first fossil, a tooth, was discovered in 1921, and the Zhoukoudian Cave has since then 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 for decades to come. The fossils became the centre of anthropological discussion, and were classified as a direct human ancestor, propping up the Out of Asia hypothesis that humans evolved in Asia.
Flying squirrels are a tribe of 50 species of squirrels in the family Sciuridae. Despite their name, they are not in fact capable of full flight in the same way as birds or bats, but they are able to glide from one tree to another with the aid of a patagium, a furred skin membrane that stretches from wrist to ankle. Their long tails also provide stability as they glide. Anatomically they are very similar to other squirrels with a number of adaptations to suit their lifestyle; their limb bones are longer and their hand bones, foot bones, and distal vertebrae are shorter. Flying squirrels are able to steer and exert control over their glide path with their limbs and tail.
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.
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.
Belomys is a genus of squirrels that contains a single extant species, the hairy-footed flying squirrel (Belomys pearsonii).
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.
Wushan Man is a set of fossilised remains of an extinct, undetermined non-hominin ape found in central China in 1985. The remains are dated to around 2 million years ago and were originally considered to represent a subspecies of Homo erectus.
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.
Nanjing Man is a specimen of Homo erectus found in China. Large fragments of one male and one female skull and a molar tooth of were discovered in 1993 in Hulu Cave on the Tangshan (汤山) hills in Jiangning District, Nanjing. The specimens were found in the Hulu limestone cave at a depth of 60–97 cm by Liu Luhong, a local worker. Dating the fossils yielded an estimated age of 580,000 to 620,000 years old.
Homo erectus is an extinct species of archaic human from the Pleistocene, with its earliest occurrence about 2 million years ago. Its specimens are among the first recognizable members of the genus Homo.
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.
Zhiren Cave is a karstic cave in the Mulan Mountains that overlooks the Hejiang River in Chongzuo, Guangxi, China. Zhiren Cave is an early Late Pleistocene site that has yielded the fossil remains of possibly anatomically modern humans with some mixed archaic human features.

Canis mosbachensis is an extinct wolf that once inhabited Europe 600,000—420,000 years ago. The Mosbach wolf was a short-legged carcass feeder adapted for scavenging megafauna on the mammoth steppe. The Mosbach wolf is proposed as the ancestor of the grey wolf Canis lupus but some mammalogists have assigned it as the subspecies Canis lupus mosbachensis.
