Blue-gray Mouse
The blue-gray mouse (''Pseudomys glaucus'') is an Australian rodent species that is only known by a few specimens found in Eastern Australia, and since presumed to have become extinct. Taxonomy The species was described by Oldfield Thomas in 1910. The number of specimens identified as ''Pseudomys glaucus'' is limited to three, two found in the northeastern state of Queensland and a single specimen collected to the south at Cryon in New South Wales. Description A species of ''Pseudomys'', these Australian rodents resembled the familiar house mouse (''Mus musculus''). The body of ''P. glaucus'' was robust with fine and dense fur, white at the underside and a pale blue-grey colour over the upperparts of the fur. The measurement of each of the three known specimens was 95 millimetres for the head and body combined, with a white-haired tail that was slightly longer (100 mm.) The weight range was 25 to 30 grams. References {{Taxonbar, from=Q882869 Pseudomys Mammals des ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Eastern Australia
The eastern states of Australia are the states adjoining the east continental coastline of Australia. These are the mainland states of Victoria, New South Wales and Queensland, and the island state of Tasmania. The Australian Capital Territory and Jervis Bay Territory, while not states, are also included. On some occasions, the southern state of South Australia is also included in this grouping due to its economic ties with the eastern states. Regardless of which definition is used, the eastern states include the great majority of the Australian population. They contain the federal capital Canberra and Australia's three largest cities Sydney, Melbourne and Brisbane (all capitals of the respective east coast states), as well as the three largest non-capital cities in the country: Gold Coast, Queensland; Newcastle, New South Wales; and Wollongong, New South Wales. In terms of climate, the area is dominated by a humid subtropical zone, with some tropical (Queensland) and oceani ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cryon
Cryon is a parish and hamlet in the north-west of New South Wales, Australia. It lies in the Walgett Shire and is situated from Sydney, west of Narrabri and east of Walgett on the Kamilaroi Highway. The settlement sits at an altitude of about . When the Walgett railway line arrived here in 1905 this was a thriving settlement with a variety of businesses including a hotel and stores. For quite a few years it was the loading point for cattle from South West Queensland South West Queensland is a remote region in the Australian state of Queensland which covers . The region lies to the south of Central West Queensland and west of the Darling Downs and includes the Maranoa district and parts of the Channel Coun ... that were railed to the Sydney market. The railway now only carries freight (grain). Only a few buildings remain, together with a wheat silo and several new bunker storages. The main industry is wheat farming with some livestock raised.

Pseudomys
''Pseudomys'' is a genus of rodent that contains a wide variety of mice native to Australia and New Guinea. They are among the few terrestrial placental mammals that colonised Australia without human intervention. Natural history This genus contains a number of species with different habits making generalisation difficult. The overall body size varies widely, ranging from 60 to 160 mm. The tail is 60–180 mm and the weight is recorded from 12 to 90 g. They inhabit a wide variety of habitats from rainforests to plains and grasslands. The animals are nocturnal and spend the day in burrows. Food also varies with some species eating seeds, roots and insects while others feed primarily on grasses. The pebble-mound mice are unique in creating mounds of stones around their burrows. Several species of ''Pseudomys'' are threatened due to competition with introduced species and habitat destruction. Several others are probably extinct. Etymology The name ''Pseudomys ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
House Mouse
The house mouse (''Mus musculus'') is a small mammal of the order Rodentia, characteristically having a pointed snout, large rounded ears, and a long and almost hairless tail. It is one of the most abundant species of the genus '' Mus''. Although a wild animal, the house mouse has benefited significantly from associating with human habitation to the point that truly wild populations are significantly less common than the semi-tame populations near human activity. The house mouse has been domesticated as the pet or fancy mouse, and as the laboratory mouse, which is one of the most important model organisms in biology and medicine. The complete mouse reference genome was sequenced in 2002. Characteristics House mice have an adult body length (nose to base of tail) of and a tail length of . The weight is typically . In the wild they vary in color from grey and light brown to black (individual hairs are actually agouti coloured), but domesticated fancy mice and laboratory mice ar ...

Mammals Described In 1910
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 wit ...

Taxa Named By Oldfield Thomas
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the int ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Extinct Rodents
Extinction is the termination of a kind of organism or of a group of kinds (taxon), usually a species. The moment of extinction is generally considered to be the death of the last individual of the species, although the capacity to breed and recover may have been lost before this point. Because a species' potential range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the fossil record) after a period of apparent absence. More than 99% of all species that ever lived on Earth, amounting to over five billion species, are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryote globally, and possibly many times more if microorganisms, like bacteria, are included. Notable extinct animal species include non-avian dinosaurs, saber-toothed cats, dodos, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
