Rabbit Rat
The rabbit rats, genus ''Conilurus'' represent an unusual genus of Old World rats from Australia, New Guinea, and Melville Island. Head and body are 16.5–20 cm. Tail length is 18–21.5 cm. The tail is haired and has a distinct tuft at the end. These nocturnal animals are found in habitats ranging from coastal areas, swamps, plains, and forests. They have been reported along the edge of oceanic surf, presumably feeding. Young have been found to cling to one of the mother's four nipples while she forages. Gestation is 33–35 days.

Early Pleistocene
The Early Pleistocene is an unofficial sub-epoch in the international geologic timescale in chronostratigraphy, being the earliest division of the Pleistocene Epoch within the ongoing Quaternary Period. It is currently estimated to span the time between 2.580 ± 0.005 Ma (million years ago) and 0.773 ± 0.005 Ma. The term Early Pleistocene applies to both the Gelasian Age (to 1.800 ± 0.005 Ma) and the Calabrian Age. While the Gelasian and the Calabrian have officially been defined by the International Union of Geological Sciences (IUGS) to effectively constitute the Early Pleistocene, the succeeding Chibanian and Tarantian ages have yet to be ratified. These proposed ages are unofficially termed the Middle Pleistocene and Late Pleistocene The Late Pleistocene is an unofficial Age (geology), age in the international geologic timescale in chronostratigraphy, also known as Upper Pleistocene from a Stratigraphy, stratigraphic perspective. It is intended to be the fourth div ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Conilurus Albipes
The white-footed rabbit rat (''Conilurus albipes'') is an extinct species of rodent, which was originally found in woodlands from Adelaide to Sydney, but became restricted to south-eastern Australia. It was kitten-sized and was one of Australia's largest native rodents. It was nocturnal and lived among trees. It made nests filled with leaves and possibly grass in the limbs of hollow eucalyptus trees. The mother carried her young attached to her teats. In a letter to John Gould, then Governor of South Australia Sir George Grey said that he removed a baby from a teat of its dead mother. The baby clung tightly to Gould's glove. Sydney natives called it 'gnar-ruck' which translates as 'rabbit-biscuit'. It was a problem in the settlers' stores at about 1788. The last specimen was recorded at about 1845, but some were reported in 1856–57 and perhaps in the 1930s. Rats may have spread diseases or competed for food with the white-footed rabbit rat. Cats may have been predators, while th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
William Ogilby
William Ogilby (1805–1873) was an Irish-born zoologist who was at the forefront of classification and naming of animal species in the 1830s and served as Secretary of the Zoological Society of London from 1839 to 1847. He removed to Ireland during the Great Famine and later built the grand but architecturally dismal Altinaghree Castle. Mount Ogilby in Queensland was named for him in 1846. Birth, family background and education Probably born in County Londonderry in 1805, William Ogilby was an illegitimate son of Leslie Ogilby (c1764-1845) who owned a bleaching green at Lackagh in the parish of Dungiven. The Ogilbys had been active in the linen trade since the mid-eighteenth century, and William's uncle Robert Ogilby (c1761-1839), having amassed a fortune as a linen factor in Dublin, bought the lease of the 22,000-acre Dungiven Castle estate and was reckoned "the wealthiest commoner in the North of Ireland, possessing it is said between ten and twenty thousand pounds a ye ...

Conilurus Capricornensis
The Capricorn rabbit rat (''Conilurus capricornensis'') is an extinct species of rodent from Queensland, Australia. It was described as a new species in 2010 on the basis of Pleistocene and Holocene dental remains. The specific name refers to the Capricorn Caves in Queensland, one of the locations where remains were unearthed. Some of the subfossil material post-dates the European settlement of Australia, so the Capricorn rabbit rat is a modern extinction. Since there has not been a targeted survey for the Capricorn rabbit rat, there is a thin hope of its survival, although this is unlikely. Description The Capricorn rabbit rat is larger than other rabbit rat (''Conilurus'') species. Also, unique dental features distinguish it from the white-footed rabbit rat (''Conilurus albipes'') and the brush-tailed rabbit rat (''Conilurus penicillatus'').

Conilurus Penicillatus
The brush-tailed rabbit rat (''Conilurus penicillatus'') is a species of rodent in the family Muridae. It is found in Australia and Papua New Guinea. Taxonomy The brush-tailed rabbit-rat is one of three ''Conilurus'' species that were extant in Australia prior to European colonisation, and represents the sole surviving species of the genus. Two other species, the white-footed rabbit-rat (''C. albipes'') and the Capricorn rabbit-rat (''C. capricornensis''), are now extinct. Morphological analysis established three subspecies of ''C. penicillatus'', of which one is on Papua New Guinea and two are present within Australia: one on the Tiwi Islands off the coast of the Northern Territory, and another on the Australian mainland. Description The brush-tailed-rabbit-rat is a moderately sized murid rodent, weighing from 116 to 216 g with a head-body length of 135 to 227 mm and a tail length of 102 to 235 mm. Typically individuals are coloured grizzled grey or brown on the upper side ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Old World Rats
The Old World rats and mice, part of the subfamily Murinae in the family Muridae, comprise at least 519 species. Members of this subfamily are called murines. In terms of species richness, this subfamily is larger than all mammal families except the Cricetidae and Muridae, and is larger than all mammal orders except the bats and the remainder of the rodents. Description The Murinae are native to Africa, Europe, Asia, and Australia. They are terrestrial placental mammals. They have also been introduced to all continents except Antarctica, and are serious pest animals. This is particularly true in island communities where they have contributed to the endangerment and extinction of many native animals. Two prominent murine species have become vital laboratory animals: the brown rat and house mouse are both used as medical subjects. The murines have a distinctive molar pattern that involves three rows of cusps instead of two, the primitive pattern seen most frequently in muro ...

Melville Island (Northern Territory)
Melville Island ( Tiwi: ''Yermalner'') is an island in the eastern Timor Sea, off the coast of the Northern Territory, Australia. Along with Bathurst Island and nine smaller uninhabited islands, it forms part of the group known as the Tiwi Islands, which are under the jurisdiction of the Northern Territory in association with the Tiwi Land Council as the regional authority. History Indigenous people have occupied the area that became the Tiwi Islands for at least 40,000 years. It is said that the first European to sight the island was Abel Tasman in 1644. Explorer Phillip Parker King (son of governor of New South Wales Philip Gidley King) named it for Robert Dundas, 2nd Viscount Melville, first Lord of the Admiralty, who is also commemorated by the much larger Melville Island in the Canadian Arctic Archipelago. Shortly after this, the British made the first attempt to settle Australia's north coast, at the short-lived Fort Dundas on Melville Island. The settlement lasted fro ...

Nocturnal Animal
Nocturnality is an animal behavior characterized by being active during the night and sleeping during the day. The common adjective is "nocturnal", versus diurnal meaning the opposite. Nocturnal creatures generally have highly developed senses of hearing, smell, and specially adapted eyesight. Some animals, such as cats and ferrets, have eyes that can adapt to both low-level and bright day levels of illumination (see metaturnal). Others, such as bushbabies and (some) bats, can function only at night. Many nocturnal creatures including tarsiers and some owls have large eyes in comparison with their body size to compensate for the lower light levels at night. More specifically, they have been found to have a larger cornea relative to their eye size than diurnal creatures to increase their : in the low-light conditions. Nocturnality helps wasps, such as ''Apoica flavissima'', avoid hunting in intense sunlight. Diurnal animals, including squirrels and songbirds, are active duri ...
