Ailuropoda is the only extant genus in the ursid (bear) subfamily Ailuropodinae. It contains one living and one or more fossil species of panda. [1] [5]
Only one species— Ailuropoda melanoleuca —currently exists; the other three species are prehistoric chronospecies. Despite its taxonomic classification as a carnivoran, the giant panda has a diet that is primarily herbivorous, which consists almost exclusively of bamboo.
Giant pandas have descended from Ailurarctos , which lived during the late Miocene. [5]
From Greek αἴλουροςaílouros "cat" + ‒ποδός‒podós "foot" (gen. sg.). Unlike most bears, giant pandas do not have round pupils, but instead have vertical slits, similar to those of cats. This has not only inspired the scientific name, but in Chinese the giant panda is called "large bear cat" (大熊猫, dà xióngmāo).
Alternatively, Ailuropoda wulingshanensis and Ailuropoda baconi may be treated as subspecies of Ailuropoda melanoleuca. [1]
The red, or lesser, panda (Ailurus fulgens) was formerly considered closely related to the giant panda. It is no longer considered a bear, however, and is now classified as the sole living representative of a different carnivore family (Ailuridae).
The giant panda, also known as the panda bear or simply panda, is a bear species endemic to China. It is characterised by its white coat with black patches around the eyes, ears, legs and shoulders. Its body is rotund; adult individuals weigh 100 to 115 kg and are typically 1.2 to 1.9 m long. It is sexually dimorphic, with males being typically 10 to 20% larger than females. A thumb is visible on its forepaw, which helps in holding bamboo in place for feeding. It has large molar teeth and expanded temporal fossa to meet its dietary requirements. It can digest starch and is mostly herbivorous with a diet consisting almost entirely of bamboo and bamboo shoots.
Dicerorhinus is a genus of the family Rhinocerotidae, consisting of a single extant species, the two-horned Sumatran rhinoceros, and several extinct species. The genus likely originated in the Mid to Late Pliocene of Northern Indochina and South China. Many species previously placed in this genus probably belong elsewhere.
Rhinoceros is a genus comprising one-horned rhinoceroses. This scientific name was proposed by Swedish taxonomist Carl Linnaeus in 1758. The genus contains two species, the Indian rhinoceros and the Javan rhinoceros. Although both members are threatened, the Javan rhinoceros is one of the most endangered large mammals in the world with only 60 individuals surviving in Java (Indonesia). The word 'rhinoceros' is of Greek origin meaning "nose-horn".
The Qinling or Qin Mountains, formerly known as the Nanshan, are a major east–west mountain range in southern Shaanxi Province, China. The mountains mark the divide between the drainage basins of the Yangtze and Yellow River systems, providing a natural boundary between North and South China and support a huge variety of plant and wildlife, some of which is found nowhere else on earth.
Gigantopithecus is an extinct genus of ape that lived in southern China from 2 million to approximately 300,000-200,000 years ago during the Early to Middle Pleistocene, represented by one species, Gigantopithecus blacki. Potential identifications have also been made in Thailand, Vietnam, and Indonesia. The first remains of Gigantopithecus, two third molar teeth, were identified in a drugstore by anthropologist Ralph von Koenigswald in 1935, who subsequently described the ape. In 1956, the first mandible and more than 1,000 teeth were found in Liucheng, and numerous more remains have since been found in at least 16 sites. Only teeth and four mandibles are known currently, and other skeletal elements were likely consumed by porcupines before they could fossilise. Gigantopithecus was once argued to be a hominin, a member of the human line, but it is now thought to be closely allied with orangutans, classified in the subfamily Ponginae.
The complex-toothed flying squirrel occurs in the southern Chinese provinces Hubei, Hunan, Guizhou, Sichuan, and Yunnan. The common name refers to the teeth, which differ from those of other species of flying squirrels.
The Qinling panda, also known as the brown panda, is a subspecies of the giant panda, discovered in 1959, but not recognized as a subspecies until 2005. Besides the nominate subspecies, it is the first giant panda subspecies to be recognized.
Ailuropodinae is a subfamily of Ursidae that contains only one extant species, the giant panda of China. The fossil record of this group has shown that various species of pandas were more widespread across the Holarctic, with species found in places such as Europe, much of Asia, North America and even Africa. The earliest pandas were not unlike other modern bear species in that they had an omnivorous diet but by around 2.4 million years ago, pandas have evolved to be more herbivorous.
Wolong National Nature Reserve, officially known as Wolong Special Administrative Region, is a national protected area located in Wenchuan County in China.
Ailuropoda microta is the earliest known ancestor of the giant panda. It measured 1 m (3 ft) in length; the modern giant panda grows to a size in excess of 1.5 m (5 ft). Wear patterns on its teeth suggest it lived on a diet of bamboo, the primary food of the giant panda. The first discovered skull of the animal in a south China limestone cave is estimated to be 2 million years old. The skull found is about half the size of a modern-day giant panda, but is anatomically very similar. This research suggests that the giant panda has evolved for more than 3 million years as a completely separate lineage from that of other bears.
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.
Ailurarctos is an extinct genus of panda from the Late Miocene of China, some 8 million years ago.
Tillodontia is an extinct suborder of eutherian mammals known from the Early Paleocene to Late Eocene of China, the Late Paleocene to Middle Eocene of North America where they display their maximum species diversity, the Middle Eocene of Pakistan, and the Early Eocene of Europe. Leaving no descendants, they are most closely related to the pantodonts, another extinct group. The tillodonts were medium- to large-sized animals that probably fed on roots and tubers in temperate to subtropical habitats.
Simosthenurus occidentalis is a species of sthenurine marsupial that existed in Australia during the Pliocene, becoming extinct in the Pleistocene epoch around 42,000 years ago. It was a large herbivorous biped that resembles large kangaroos, but with a heavier body than modern kangaroos. The structure of the skull and teeth - resembling koalas and panda bears - indicates that it consumed tough vegetation.
Ailuropoda baconi is an extinct panda known from cave deposits in South China, Laos, Vietnam, Myanmar, and Thailand from the Late Pleistocene, 750,000 years ago, and was preceded by A. wulingshanensis and A. microta as an ancestor of the giant panda. Very little is known about this animal; however, its latest fossils have been dated to the Late Pleistocene.
Agriotheriini is an extinct tribe of ailuropodine bears from the middle Neogene to early Quaternary periods, with fossils found from Eurasia, Africa, and North America.
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.
Hualong Cave is a cave in Pangwang village in Dongzhi County, Anhui Province, China, and situated on the southern bank of Yangtze. It is located on the side of Meiyuan Hill. Palaeontological interest started in 2004 when a farmer accidentally found bones that were later identified as mammalian fossils. Excavations started in 2006 by paleontologists from the Chinese Academy of Sciences. It has yielded many stone tools and over 30 human fossils, and animal bones including those of Ailuropoda, Arctonyx, Bubalus, Sinomegaceros, Stegodon, giant tapir, and giant pandas. The most notable fossils are those of the Hualongdong people, including Homo erectus described in 2014, and that of a 300,000-year-old archaic human discovered in 2019.
Hesperotherium is a genus of chalicotheres from the Early to Middle Pleistocene of China. Along with Nestoritherium, it was one of the last of the chalicotheres to ever exist. It belonged to the subfamily Chalicotheriinae, which also includes Anisodon, Chalicotherium and Nestoritherium.
