Woolly Flying Squirrel
''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 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 the Yunn ...

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 ...

Eupetaurus Nivamons
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 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 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. In 2020, during a biodiversity survey conducted in northwester ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
India
India, officially the Republic of India (Hindi: ), is a country in South Asia. It is the seventh-largest country by area, the second-most populous country, and the most populous democracy in the world. Bounded by the Indian Ocean on the south, the Arabian Sea on the southwest, and the Bay of Bengal on the southeast, it shares land borders with Pakistan to the west; China, Nepal, and Bhutan to the north; and Bangladesh and Myanmar to the east. In the Indian Ocean, India is in the vicinity of Sri Lanka and the Maldives; its Andaman and Nicobar Islands share a maritime border with Thailand, Myanmar, and Indonesia. Modern humans arrived on the Indian subcontinent from Africa no later than 55,000 years ago., "Y-Chromosome and Mt-DNA data support the colonization of South Asia by modern humans originating in Africa. ... Coalescence dates for most non-European populations average to between 73–55 ka.", "Modern human beings—''Homo sapiens''—originated in Africa. Then, int ...

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 ...

Cladistics
Cladistics (; ) is an approach to biological classification in which organisms are categorized in groups (" clades") based on hypotheses of most recent common ancestry. The evidence for hypothesized relationships is typically shared derived characteristics ( synapomorphies'')'' that are not present in more distant groups and ancestors. However, from an empirical perspective, common ancestors are inferences based on a cladistic hypothesis of relationships of taxa whose character states can be observed. Theoretically, a last common ancestor and all its descendants constitute a (minimal) clade. Importantly, all descendants stay in their overarching ancestral clade. For example, if the terms ''worms'' or ''fishes'' were used within a ''strict'' cladistic framework, these terms would include humans. Many of these terms are normally used paraphyletically, outside of cladistics, e.g. as a 'grade', which are fruitless to precisely delineate, especially when including extinct species. R ...

Petaurista
''Petaurista'' is a genus of rodent in the family Sciuridae. They are large to very large flying squirrels found in forests and other wooded habitats in southern and eastern Asia. Like other flying squirrels, they are mostly nocturnal and able to glide (not actually fly like a bat) long distances between trees by spreading out their patagium, skin between their limbs. They feed primarily on plant material, but will also take small animals such as insects. Taxonomy The species level taxonomy is very complex and not fully resolved. In 2005, ''Mammal Species of the World'' recognised eight species, but later studies have found that some of these were highly polyphyletic, and recent authorities have often recognised some of the most divergent "subspecies" as valid species. Additionally, three new species were described from northeastern India in 2007–2013, although their validity needs to be confirmed. Living species Eight species were recognised in ''Mammal Species of the Wo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lower Jaw
In anatomy, the mandible, lower jaw or jawbone is the largest, strongest and lowest bone in the human facial skeleton. It forms the lower jaw and holds the lower teeth in place. The mandible sits beneath the maxilla. It is the only movable bone of the skull (discounting the ossicles of the middle ear). It is connected to the temporal bones by the temporomandibular joints. The bone is formed in the fetus from a fusion of the left and right mandibular prominences, and the point where these sides join, the mandibular symphysis, is still visible as a faint ridge in the midline. Like other symphyses in the body, this is a midline articulation where the bones are joined by fibrocartilage, but this articulation fuses together in early childhood.Illustrated Anatomy of the Head and Neck, Fehrenbach and Herring, Elsevier, 2012, p. 59 The word "mandible" derives from the Latin word ''mandibula'', "jawbone" (literally "one used for chewing"), from '' mandere'' "to chew" and ''-bula'' (ins ...

Cranium
The skull is a bone protective cavity for the brain. The skull is composed of four types of bone i.e., cranial bones, facial bones, ear ossicles and hyoid bone. However two parts are more prominent: the cranium and the mandible. In humans, these two parts are the neurocranium and the viscerocranium ( facial skeleton) that includes the mandible as its largest bone. The skull forms the anterior-most portion of the skeleton and is a product of cephalisation—housing the brain, and several sensory structures such as the eyes, ears, nose, and mouth. In humans these sensory structures are part of the facial skeleton. Functions of the skull include protection of the brain, fixing the distance between the eyes to allow stereoscopic vision, and fixing the position of the ears to enable sound localisation of the direction and distance of sounds. In some animals, such as horned ungulates (mammals with hooves), the skull also has a defensive function by providing the mount (on the fron ...
