Neodon Forresti
Forrest's mountain vole (''Neodon forresti'') is a species of rodent in the family Cricetidae found within China in northwest Yunnan. The initial study by Hinton in 1923 identified it as morphologically close to the Chinese scrub vole (''N. irene'') but with a larger body size and longer and darker pelage.

Martin Hinton
Martin Alister Campbell Hinton FRS (29 June 1883 – 3 October 1961) was a British zoologist. Career Hinton joined the staff of the Natural History Museum in 1910, working on mammals, in particular rodent Rodents (from Latin , 'to gnaw') are mammals of the Order (biology), order Rodentia (), which are characterized by a single pair of continuously growing incisors in each of the upper and lower jaws. About 40% of all mammal species are roden ...s. He became Deputy Keeper of Zoology in 1927 and Keeper in 1936, retiring in 1945. Hinton is among those associated with the Piltdown Man hoax, a composite of an altered human skull and ape jawbone planted, and subsequently 'discovered', at a dig in Piltdown, England, and presented as a missing link between man and ape. A trunk belonging to Hinton left in storage at the Natural History Museum and found in 1970 contained animal bones and teeth carved and stained in a manner similar to the Piltdown finds, and raising question ...

Rodent
Rodents (from Latin , 'to gnaw') are mammals of the Order (biology), order Rodentia (), which are characterized by a single pair of continuously growing incisors in each of the upper and lower jaws. About 40% of all mammal species are rodents. They are native to all major land masses except for New Zealand, Antarctica, and several oceanic islands, though they have subsequently been introduced to most of these land masses by human activity. Rodents are extremely diverse in their ecology and lifestyles and can be found in almost every terrestrial habitat, including human-made environments. Species can be arboreal, fossorial (burrowing), saltatorial/richochetal (leaping on their hind legs), or semiaquatic. However, all rodents share several morphological features, including having only a single upper and lower pair of ever-growing incisors. Well-known rodents include Mouse, mice, rats, squirrels, prairie dogs, porcupines, beavers, guinea pigs, and hamsters. Rabbits, hares, and ...

Cricetidae
The Cricetidae are a family of rodents in the large and complex superfamily Muroidea. It includes true hamsters, voles, lemmings, muskrats, and New World rats and mice. At almost 608 species, it is the second-largest family of mammals, and has members throughout the Americas, Europe and Asia. Characteristics The cricetids are small mammals, ranging from just in length and in weight in the New World pygmy mouse up to and in the muskrat. The length of their tails varies greatly in relation to their bodies, and they may be either furred or sparsely haired. The fur of most species is brownish in colour, often with a white underbelly, but many other patterns exist, especially in the cricetine and arvicoline subfamilies. Like the Old World mice, cricetids are adapted to a wide range of habitats, from the high Arctic to tropical rainforests and hot deserts. Some are arboreal, with long balancing tails and other adaptations for climbing, while others are semiaquatic, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yunnan
Yunnan , () is a landlocked province in the southwest of the People's Republic of China. The province spans approximately and has a population of 48.3 million (as of 2018). The capital of the province is Kunming. The province borders the Chinese provinces of Guizhou, Sichuan, autonomous regions of Guangxi, and Tibet as well as Southeast Asian countries: Vietnam, Laos, and Myanmar. Yunnan is China's fourth least developed province based on disposable income per capita in 2014. Yunnan is situated in a mountainous area, with high elevations in the northwest and low elevations in the southeast. Most of the population lives in the eastern part of the province. In the west, the altitude can vary from the mountain peaks to river valleys by as much as . Yunnan is rich in natural resources and has the largest diversity of plant life in China. Of the approximately 30,000 species of higher plants in China, Yunnan has perhaps 17,000 or more. Yunnan's reserves of aluminium, lead, ...

Chinese Scrub Vole
The Chinese scrub vole, or Irene's mountain vole, (''Neodon irene'') is a species of rodent in the family Cricetidae. It is endemic to mountainous parts of southern China and is very similar to the Sikkim mountain vole in appearance. The International Union for Conservation of Nature has assessed its conservation status as being of " least concern". Description The Chinese scrub vole has a head-and-body length of between and a tail length of . The dorsal fur is greyish-brown, the underparts are dark grey and there is an intermediate strip of ochre-brown where the two colours meet. The upper surface of both fore and hind feet are brownish-white and the tail is bicoloured, being brown above and white below. The Chinese scrub vole is very similar in appearance to the Sikkim mountain vole (''Neodon sikimensis''), but it is slightly smaller and the two can be distinguished by examination of their dentition. Distribution and habitat The Chinese scrub vole is endemic to China where ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pelage
Fur is a thick growth of hair that covers the skin of mammals. It consists of a combination of oily guard hair on top and thick underfur beneath. The guard hair keeps moisture from reaching the skin; the underfur acts as an insulating blanket that keeps the animal warm. The fur of mammals has many uses: protection, sensory purposes, waterproofing, and camouflaging, with the primary usage being thermoregulation. The types of hair include * ''definitive'', which may be shed after reaching a certain length; * ''vibrissae'', which are sensory hairs and are most commonly whiskers; * ''pelage'', which consists of guard hairs, under-fur, and awn hair; * '' spines'', which are a type of stiff guard hair used for defense in, for example, porcupines; * ''bristles'', which are long hairs usually used in visual signals, such as the mane of a lion; * ''velli'', often called "down fur", which insulates newborn mammals; and * ''wool'', which is long, soft, and often curly. Hair length ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neodon
''Neodon'' is a genus of rodent in the family Cricetidae. Species within ''Neodon'' are classified as relics of the Pleistocene epoch because the occlusal patterns resemble the extinct '' Allophaiomys''. The genus ''Neodon'' contains the following species: * Chinese scrub vole (''Neodon irene'') * Sikkim mountain vole (''Neodon sikimensis'') * Forrest's mountain vole (''Neodon forresti'') * Linzhi mountain vole The Linzhi mountain vole (''Neodon linzhiensis'') is a species of rodent in the family Cricetidae.

Mammals Described In 1923
Mammals () are a group of vertebrate animals constituting the class Mammalia (), characterized by the presence of mammary glands which in females produce milk for feeding (nursing) their young, a neocortex (a region of the brain), fur or hair, and three middle ear bones. These characteristics distinguish them from reptiles (including birds) from which they diverged in the Carboniferous, over 300 million years ago. Around 6,400 extant species of mammals have been described divided into 29 orders. The largest orders, in terms of number of species, are the rodents, bats, and Eulipotyphla (hedgehogs, moles, shrews, and others). The next three are the Primates (including humans, apes, monkeys, and others), the Artiodactyla (cetaceans and even-toed ungulates), and the Carnivora (cats, dogs, seals, and others). In terms of cladistics, which reflects evolutionary history, mammals are the only living members of the Synapsida (synapsids); this clade, together with S ...
