Bettongia anhydra, also known as desert bettong, is a recently extinct species of potoroine marsupial.
A skull collected in the 1930s that was placed as Bettongia penicillata anhydra, and later regarded as a synonym of Bettongia lesueur . The first description was by Hedley Herbert Finlayson, published in 1957. [1] [2] An examination of morphology and molecular evidence proposed this specimen as the type of this new species. The type was collected from a fresh carcass at Lake Mackay in the western Northern Territory by Michael Terry in 1933. [3]
The phylogeny of the species separates this species and B. lesueur from lineages that emerged at a later period. [3]
A species of genus Bettongia , small to medium sized mammals that are usually nocturnal and fungivorous. The dentary of Bettongia anhydra resembles that of the Potorous species and those of the bettong genus. [3]
The order Peramelemorphia includes the bandicoots and bilbies; it equates approximately to the mainstream of marsupial omnivores. All members of the order are endemic to the twin land masses of Australia-New Guinea and most have the characteristic bandicoot shape: a plump, arch-backed body with a long, delicately tapering snout, very large upright ears, relatively long, thin legs, and a thin tail. Their size varies from about 140 grams up to 4 kilograms, but most species are about one kilogram, or the weight of a half-grown kitten.
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.
Potoroidae is a family of marsupials, small Australian animals known as bettongs, potoroos, and rat-kangaroos. All are rabbit-sized, brown, jumping marsupials and resemble a large rodent or a very small wallaby.
The banded hare-wallaby, mernine, or munning is a marsupial currently found on the Islands of Bernier and Dorre off western Australia. Reintroduced populations have recently been established on islands and fenced mainland sites, including Faure Island and Wadderin Sanctuary near Narembeen in the central wheatbelt.
The woylie or brush-tailed bettong is an extremely rare, small marsupial, belonging to the genus Bettongia, that is endemic to Australia. There are two subspecies: B. p. ogilbyi, and the now extinct B. p. penicillata.
Chaeropus, known as the pig-footed bandicoots, is a genus of small mammals that became extinct during the twentieth century. They were unique marsupials, of the order Peramelemorphia, with unusually thin legs yet were able to move rapidly. Two recognised species inhabited dense vegetation on the arid and semi-arid plains of Australia. The genus' distribution range was later reduced to an inland desert region, where it was last recorded in the 1950s; it is now presumed extinct.
The eastern bettong, also known as the Balbo, southern bettong and Tasmanian bettong, is a bettong whose natural range includes southeastern Australia and eastern Tasmania.
The musky rat-kangaroo is a small marsupial found only in the rainforests of northeastern Australia. First described in the later 19th century, the only other species are known from fossil specimens. They are similar in appearance to potoroos and bettongs, but are not as closely related. Their omnivorous diet is known to include materials such as fruit and fungi, as well as small animals such as insects and other invertebrates. The local Aboriginal name for the species is durrgim yuri.
The northern bettong is a small potoroid marsupial which is restricted to some areas of mixed open Eucalyptus woodlands and Allocasuarina forests bordering rainforests in far northeastern Queensland, Australia. They are known as "rat kangaroos" and move about in a slow hopping manner. There are five different species in Australia of this particular animal. It is about the size of a rabbit with a large tail dragging behind.
Palorchestes is an extinct genus of terrestrial, herbivorous marsupials of the family Palorchestidae. The genus was endemic to Australia, living from the Miocene through to the Pleistocene epochs.
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. 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. The broad-faced potoroo P. platyops disappeared after its first description in the 19th century. The main threats are predation by introduced species and habitat loss.
Ekaltadeta is an extinct genus of marsupials related to the modern musky rat-kangaroos. Ekaltadelta was present in what is today the Riversleigh formations in Northern Queensland from the Late Oligocene to the Miocene.
The Macropodiformes, also known as macropods, are one of the three suborders of the large marsupial order Diprotodontia. They may in fact be nested within one of said suborders, Phalangeriformes. Kangaroos, wallabies and allies, bettongs, potoroos and rat kangaroos are all members of this suborder.
The boodie, also known as the burrowing bettong, or Lesueur's rat-kangaroo, is a small marsupial. Its population is an example of the effects of introduced animals on Australian fauna and ecosystems. Once the most common macropodiform mammal on the whole continent, the boodie now only lives on off-lying islands and in a newly introduced population on the mainland at Shark Bay. This animal, first collected during an 1817 French expedition of the west coast, was named after Charles Lesueur, an artist and naturalist who accompanied a previous French expedition.
Bettongs, species of the genus Bettongia, are potoroine marsupials once common in Australia. They are important ecological 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.
The Nullarbor dwarf bettong, Bettongia pusilla, was a potoroine marsupial that occurred in Australia. The animal is only known from skeletons found in caves of the Nullarbor Plain and is now classified as recently extinct.
The Macropodidae are an extant family of marsupial with the distinction of the ability to move bipedally on the hind legs, sometimes by jumping, as well as quadrupedally. They are herbivores, but some fossil genera like Ekaltadeta are hypothesised to have been carnivores. The taxonomic affiliations within the family and with other groups of marsupials is still in flux.
Heirisson Prong is a community managed reserve established for the conservation of threatened mammals at Shark Bay in Western Australia. The reserve is at the point of a long narrow peninsula of the same name that juts into Shark Bay from the south.
Ekaltadeta ima is a species of potoroid marsupial that existed in Miocene Australia.
Bettongia moyesi is a fossil species of potoroid marsupial.
