Potoroini
Potoroo is a common name for species of ''Potorous'', a genus of smaller marsupials. They are allied to the Macropodiformes, the suborder of kangaroo, wallaby, and other rat-kangaroo genera and is the only genus in the tribe Potoroini. All three extant species are threatened by ecological changes since the colonisation of Australia, especially the long-footed potoroo ''Potorous longipes'' (endangered) and '' P. gilbertii'' (critically endangered). The broad-faced potoroo '' P. platyops'' disappeared after its first description in the 19th century. The main threats are predation by introduced species (especially foxes) and habitat loss. Potoroos were formerly very common in Australia, and early settlers reported them as being significant pests to their crops. Status Gilbert's potoroo was first described in the West in 1840 by naturalist John Gilbert. It was then thought to have become extinct until being rediscovered in 1994 at the Two Peoples Bay Nature Reserve (near Albany) ...

Potoroinae
Potoroidae is a family of marsupials, small Australian animals known as Bettong, bettongs, Potoroo, potoroos, and rat-kangaroos. All are rabbit-sized, brown, jumping marsupials and resemble a large rodent or a very small wallaby. Taxonomy The potoroids are smaller relatives of the kangaroos and wallabies, and may be ancestral to that group. In particular, the teeth show a simpler pattern than in the Macropodidae, kangaroo family, with longer upper incisors, larger canine (tooth), canines, and four cusps on the Molar (tooth), molars. However, both groups possess a wide diastema (dentistry), diastema between the incisors and the cheek teeth, and the potoroids have a similar dental formula to their larger relatives: In most respects, however, the potoroids are similar to small wallabies. Their hind feet are elongated, and they move by hopping, although the adaptations are not as extreme as they are in true wallabies, and, like rabbits, they often use their fore limbs to move abou ...

Potorous Platyops
The broad-faced potoroo (''Potorous platyops'') is an extinct potoroid marsupial that was found in southwestern Australia. The first specimen was collected in 1839, and described by John Gould in 1844. Only a small number of specimens have been collected since. The last live capture was in 1875. Subfossil remains indicate that it had an extensive distribution around the semiarid coastal districts of Southwest Australia. The habitat of the broad-faced potoroo is almost entirely unknown, but unlike its relatives, such as the long-nosed potoroo ''Potorous tridactylus'' and long-footed ''Potorous longipes'', they do not seem to have lived in dense understories in forests. Preserved specimens indicate that it was smaller than other potoroos at around 300 mm (1 ft) long with a 180-mm tail. Their weight is estimated at 800 g. Their coat was grizzled with yellowish hairs above and greyish white below. Their body was similar in shape to that of other potoroids. Their ears were small and ...

John Gilbert (naturalist)
John Gilbert (c. 1812 – 28 June 1845) was an English natural history, naturalist and exploration, explorer. Gilbert is often cited in the earliest descriptions of many Australian animals, many of which were unrecorded in European literature, and some of these are named for him by those authors. Gilbert was sent to the newly founded Swan River Colony and made collections and notes on the unique birds and mammals of the surrounding region. He later joined expeditions to remote parts the country, continuing to make records and collections until he was killed during a violent altercation at Mitchell River (Queensland) on the Cape York Peninsula. Early life John Gilbert was born in about 1812 in Newington Butts, south London, England, and was christened on 25 October 1812 at Spa Fields Lady Huntingdon's, Clerkenwell, London. His father was William, and his mother was Ann, who was from nearby villages in Kent. Gilbert was a taxidermist for the Zoological Society of London, where he ...

Palaeopotoroinae
''Palaeopotorous priscus'' is a fossil species of a diprotodont marsupial, known from specimens obtained in central Australia. The animal was similar to the modern species of the family Potoroidae, the potoroos and bettongs. Taxonomy The only known species of its genus, ''Palaeopotorous'', which has been allied to the subfamily Potoroinae or as the type of a subfamily, Palaeopotoroinae, in the potoroid family. Description The dental evidence of the species indicates it was a similar size to a small to medium rat-kangaroos that were common into the twentieth century. Since its first discovery, the species has been suspected of representing an early lineage of the macropods. The finds have been placed to the late Oligocene The Chattian is, in the geologic timescale The geologic time scale or geological time scale (GTS) is a representation of time based on the rock record of Earth.

Hypsiprymnodontidae
The Hypsiprymnodontidae are a family of macropods, one of two families containing animals commonly referred to as rat-kangaroos. The single known extant genus and species in this family, the musky rat-kangaroo, ''Hypsiprymnodon moschatus'', occurs in northern Australia. During the Pleistocene, this family included the megafauna In zoology, megafauna (from Ancient Greek, Greek μέγας ''megas'' "large" and Neo-Latin ''fauna'' "animal life") are large animals.

Aepyprymnus
The rufous rat-kangaroo or rufous bettong (''Aepyprymnus rufescens'') is a small, jumping, rat-like marsupial native to eastern Australia. It is the only species in the genus ''Aepyprymnus''. The largest member of the potoroo/bettong family ( Potoroidae), it is about the size of a rabbit. The rufous rat-kangaroo is active at night when it digs for plant roots and fungi, and like other marsupials it carries its young in a pouch. Though its range is reduced, the population is healthy and stable. Taxonomy The rufous rat-kangaroo is the only member of its genus, and is the largest of all the potoroids. It is generally grey with a hint of reddish brown and its scientific name means "reddish high-rump". It was once thought of as a solitary, nocturnal animal, but recent observation indicates that the rufous rat-kangaroo may form loose, polygynous associations. It feeds mostly on tubers and fungi, but also on leaves and other vegetation. Description A species of the family Potoroid ...

Bettongia
Bettongs, species of the genus ''Bettongia'', are potoroine marsupials once common in Australia. They are important ecosystem engineers displaced during the colonisation of the continent, and are vulnerable to threatening factors such as altered fire regimes, land clearing, pastoralism and introduced predatory species such as the fox and cat. Conservation status All species of the genus have been severely affected by ecological changes since the European colonisation of Australia. Those that have not become extinct became largely confined to islands and protected reserves and are dependent on re-population programs. The diversity of the genus was poorly understood before their extirpation from the mainland, and new taxa have been identified in specimens newly discovered and already held in museum collections. In August 2021, 40 bettongs were released in different parts of South Australia after being raised in captivity to increase their numbers. Taxonomy Four extant specie ...

Illiger
Johann Karl Wilhelm Illiger (19 November 1775 – 10 May 1813) was a German entomologist and zoologist. He founded the entomological periodical ''Magazin für Insektenkunde.'' The plant genus '' Illigera'' is named in his honour. Biography Illiger was the son of a merchant in Braunschweig. He studied under the entomologist Johann Hellwig, and later worked on the zoological collections of Johann Centurius Hoffmannsegg. He was educated at the University of Helmstedt and at Gottingen. He was unable to pursue medical studies due to tuberculosis. Illiger was invited to Berlin by Alexander von Humboldt and he became professor and director of the "zoological museum" (which is the Natural History Museum of Berlin in the present day) from its formation in 1810 until his death three years later from tuberculosis. He was the author of ''Prodromus systematis mammalium et avium'' (1811), which was an overhaul of the Linnaean system. It was a major influence on the adoption of the concept ...

Oldfield Thomas
Michael Rogers Oldfield Thomas (21 February 1858 – 16 June 1929) was a British zoologist. Career Thomas worked at the Natural History Museum, London, 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, 1st Baronet, 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 to rearrange the exhibitions, allowing Thomas to concentrate on these new specimens. Thomas viewed his taxonomy efforts from the scope of British impe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Macropodid
Macropodidae is a family of marsupials that includes kangaroos, wallabies, tree-kangaroos, wallaroos, pademelons, quokkas, and several other groups. These genera are allied to the suborder Macropodiformes, containing other macropods, and are native to the Australian continent (the mainland and Tasmania), New Guinea and nearby islands. Description Although omnivorous kangaroos lived in the past, these were not members of the family Macropodidae; modern macropods are generally herbivorous. Some are browsers, but most are grazers and are equipped with appropriately specialised teeth for cropping and grinding up fibrous plants, in particular grasses and sedges. Modern omnivorous kangaroos generally belong to a different family (for example, the Musky rat-kangaroo). In general, macropods have a broad, straight row of cutting teeth at the front of the mouth, no canine teeth, and a gap before the molars. The molars are large and, unusually, do not appear all at once but a pai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dharug
The Dharug or Darug people, are a nation of Aboriginal Australian clans, who share ties of kinship, country and culture. In pre-colonial times, they lived as hunters in the region of current day Sydney. The Darug speak one of two dialects of the Dharug language related to their coastal or inland groups. There was armed conflict between the Dharug and the English settlers in the first half of the 19th century. Controversy over land rights, deference to culture and official return of Dharug artifacts, such as the skull of the warrior Pemulwuy, were a main cause of such conflict. Dharug country Dharug country covers an area of approximately 6,000 km2 (2,300 square miles). In the north, it reaches the Hawkesbury River and its mouth at Broken Bay, creating a border with the Awabakal. To the northwest, the Dharug country extends to the town of Mount Victoria in the Blue Mountains meeting the Darkinjung. To the west, Wiradjuri country begins at the eastern fringe of the B ...
