Eupetaurus
''Eupetaurus'' is a genus of rodent in the family Sciuridae. Members of this genus are known as woolly flying squirrels. They are large to very large flying squirrels found in the highest rocky cliffs near the Tree line, treeline of the Himalayas and Tibetan Plateau. Due to the inaccessibility of their montane habitat, they are difficult to study. Taxonomy Flying squirrels in the central and eastern Himalayas have been separated from those in the western Himalayas by the Ganges and Yarlung Tsangpo rivers, and are thought to have diverged in the Neogene, between 4.5 to 10.2 million years ago. Species For more than a century since its description by Oldfield Thomas, the only species in the genus was thought to be the western woolly flying squirrel (''E. cinereus''), which is found in northern Pakistan and northwestern India. However, an analysis of museum specimens found evidence of two more species in the eastern Himalayas, the Tibetan woolly flying squirrel (''E. tibetensis'') and ...

Eupetaurus Cinereus
The western woolly flying squirrel (''Eupetaurus cinereus'') is a species of very large flying squirrel in the genus '' Eupetaurus''. It is native to northern Pakistan and northwestern India. It was long considered the only species in the genus until the description of two other species in 2021. Until recently, scientific knowledge of this rare species was limited to 11 skins collected in the late nineteenth century. However, recent research has confirmed that it remains in Kashmir Kashmir () is the northernmost geographical region of the Indian subcontinent. Until the mid-19th century, the term "Kashmir" denoted only the Kashmir Valley between the Great Himalayas and the Pir Panjal Range. Today, the term encompas .... It is among the longest members of the family Sciuridae, and one of the biggest gliding animals known. Observations confirm that despite its size, it does glide effectively, like other flying squirrels. Distribution and description ''E. cinereus'' ha ...

Yunnan Woolly Flying Squirrel
The Yunnan woolly flying squirrel (''Eupetaurus nivamons'') is a species of very large flying squirrel in the genus ''Eupetaurus''. It is found on the southeastern margin of the Himalayas, namely in northwestern Yunnan and potentially Myanmar. It is thought to be the Sister group, sister species to the Tibetan woolly flying squirrel (''E. tibetensis''), from which it likely diverged during the Pliocene-Pleistocene boundary. It differs from the western woolly flying squirrel (''E. cinereus'') in its more saturated brown dorsal pelage, and differs from ''E. tibetensis'' in its much shorter black tail tip. It also has a much wider Rostrum (anatomy), rostrum than the other two ''Eupetaurus'' species. It has been documented (through both specimens and camera trap images) from two localities; Mount Gaoligong, the highest peak of the Gaoligong Mountains and a nationally protected nature reserve, and Biluo Snow Mountain, which is currently unprotected.

Tibetan Woolly Flying Squirrel
The Tibetan woolly flying squirrel (''Eupetaurus tibetensis'') is a species of very large flying squirrel in the genus ''Eupetaurus''. It is found in the south-central portion of the Tibetan Plateau, namely south-central Tibet, northern Sikkim, and western Bhutan. It is thought to be the sister species to the Yunnan woolly flying squirrel (''E. nivamons''), from which it likely diverged during the Pliocene-Pleistocene boundary. It differs from the western woolly flying squirrel (''E. cinereus'') in its saturated brown pelage with a reddish tinge, and differs from ''E. nivamons'' in its black tail tip being much longer than that of ''E. nivamons''. Although its existence was known since 1879, due to the very few specimens collected, it remained undescribed until 2021. It is only known from several historical specimens. It has been recommended that it be classified as Data Deficient on the IUCN Red List The International Union for Conservation of Nature (IUCN) Red List of Th ...

Flying Squirrels
Flying squirrels (scientifically known as Pteromyini or Petauristini) 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 parachute-like 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. Molecular studies have shown that flying squirrels are monophyletic and originated some 18–20 million years ago. The genus Paracitellus is the earliest lineage to the flying squirrel dating back to the late Oligocene era. Most are nocturnal ...

Oldfield Thomas
Michael Rogers Oldfield Thomas (21 February 1858 – 16 June 1929) was a British zoologist. Career Thomas worked at the Natural History Museum on mammals, describing about 2,000 new species and subspecies for the first time. He was appointed to the museum secretary's office in 1876, transferring to the zoological department in 1878. In 1891, Thomas married Mary Kane, daughter of Sir Andrew Clark, heiress to a small fortune, which gave him the finances to hire mammal collectors and present their specimens to the museum. He also did field work himself in Western Europe and South America. His wife shared his interest in natural history, and accompanied him on collecting trips. In 1896, when William Henry Flower took control of the department, he hired Richard Lydekker Richard Lydekker (; 25 July 1849 – 16 April 1915) was an English naturalist, geologist and writer of numerous books on natural history. Biography Richard Lydekker was born at Tavistock Square in London. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Biswamoyopterus
''Biswamoyopterus'' is a genus of rodent in the family Sciuridae. It contains three known species of very large flying squirrels, with '' B. laoensis'' being among the longest of all squirrels. They are distributed in forests in northeast India, southwest China and Laos. Despite their size, species in this genus tend to be very elusive; due to this, all of them have been described relatively recently. Additionally, they are easily confused with certain ''Petaurista'' giant flying squirrels that are more common and overlap in range with the rare ''Biswamoyopterus''. Species There are currently three known species in this genus: * Namdapha flying squirrel ''Biswamoyopterus biswasi'' * Laotian giant flying squirrel The Laotian giant flying squirrel (''Biswamoyopterus laoensis'') is an arboreal, flying squirrel endemic to Laos. It was the second described member in the genus ''Biswamoyopterus'', after being first collected in September 2012 by scientists res ... ''Biswamoyo ...
