The southern pig-footed bandicoot (Chaeropus ecaudatus) was a small species of herbivorous marsupial in the genus Chaeropus , the pig-footed bandicoots.
The description of the population was revised in 2019, separating a central western population as Chaeropus yirratji and recognised two earlier descriptions as subspecies Chaeropus ecaudatus ecaudatus (found in southeastern Australia) and Chaeropus ecaudatus occidentalis (found in western and southwestern Australia). [2]
It has been believed to be extinct since the mid-20th century, having reportedly vanished from its final refuge in southern Australia by 1945. [3] It was presumably the first of the two species of Chaeropus to go extinct. Pig footed-bandicoots were the only marsupials to walk on reduced digits both on the fore and hind feet. In addition, the pig footed-bandicoot diverges from two different species. According to molecular phylogenetic analyses they diverged from other bandicoots like the Peramelidae, and also from the bilbies like Thylacomyidae in the mid-Late Oligocene. [4]
It is thought to have been distributed in shrubland habitats in the southern regions of Australia's deserts, and its range likely extended to Western Australia. It physically closely resembled the northern pig-footed bandicoot (C. yirratji), but it had fewer holes on its palate and shorter feet. It also had a different dentition than C. yirratji, indicating that it may have had a different diet. C. ecaudatus rapidly adapted to drying conditions and changing environment, quickly becoming a grazer in a short period of time C. ecaudatus is thought to have undergone rapid herbivorous evolution due to lesser high crown and lateral blade development on the lower molars found in an ancestral species, Chaeropus baynesi. [4] The two species were formerly considered conspecific until a study released in 2019 found them to be separate species. [5] [6] This species likely went extinct due to predation by introduced red foxes and feral cats, as well as habitat degradation by introduced livestock. [7]
Diprotodontia is the largest extant order of marsupials, with about 155 species, including the kangaroos, wallabies, possums, koala, wombats, and many others. Extinct diprotodonts include the hippopotamus-sized Diprotodon, and Thylacoleo, the so-called "marsupial lion".
Macrotis is a genus of desert-dwelling marsupial omnivores known as bilbies or rabbit-bandicoots; they are members of the order Peramelemorphia. At the time of European colonisation of Australia, there were two species. The lesser bilby became extinct in the 1950s; the greater bilby survives but remains endangered. It is currently listed as a vulnerable species. The greater bilby is on average 55 cm (22 in) long, excluding the tail, which is usually around 29 cm (11 in) long. Its fur is usually grey or white; it has a long, pointy nose and very long ears, hence the reference of its nickname to rabbits.
The order Peramelemorphia includes the bandicoots and bilbies. All members of the order are endemic to 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.
Bandicoots are a group of more than 20 species of small to medium-sized, terrestrial, largely nocturnal marsupial omnivores in the order Peramelemorphia. They are endemic to the Australia–New Guinea region, including the Bismarck Archipelago to the east and Seram and Halmahera to the west.
Australidelphia is the superorder that contains roughly three-quarters of all marsupials, including all those native to Australasia and a single species — the monito del monte — from South America. All other American marsupials are members of the Ameridelphia. Analysis of retrotransposon insertion sites in the nuclear DNA of a variety of marsupials has shown that the South American monito del monte's lineage is the most basal of the superorder.
Chaeropus, known as the pig-footed bandicoots, is a genus of small marsupials that became extinct during the 20th century. They were the only members of the family Chaeropodidae in order Peramelemorphia, with unusually thin legs, yet were able to move rapidly. Two recognised species inhabited dense vegetation on the arid and semiarid 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.
Perameles is a genus of marsupials of the order Peramelemorphia. They are referred to as long-nosed bandicoots or barred bandicoots.
The short-nosed bandicoots are members of the order Peramelemorphia. These marsupials can be found across Australia, although their distribution can be patchy. Genetic evidence suggests that short-nosed bandicoots diverged from the related long-nosed species around eight million years ago, during the Miocene epoch, and underwent a rapid diversification around three million years ago, during the late Pliocene.
The marsupial family Peramelidae contains the extant bandicoots. They are found throughout Australia and New Guinea, with at least some species living in every available habitat, from rainforest to desert. Four fossil peramelids are described. One known extinct species of bandicoot, the pig-footed bandicoot, was so different from the other species, it was recently moved into its own family.
The southern brown bandicoot is a short-nosed bandicoot, a type of marsupial, found mostly in southern Australia. A subspecies in Western Australia was also known as the quenda in South Western Australia. This subspecies was elevated to species in 2018.
The Western barred bandicoot, also known as the Shark Bay bandicoot or the Marl, is a small species of bandicoot; now extinct across most of its former range, the western barred bandicoot only survives on offshore islands and in fenced sanctuaries on the mainland.
The northern pig-footed bandicoot was a small species of extinct herbivorous Australian marsupial in the genus Chaeropus, the pig-footed bandicoots. It has been believed to be extinct since the mid-20th century; the last confirmed observation was a specimen collected near Alice Springs in 1901, but reports from local Aborigines indicate that it may have survived in the Gibson and Great Sandy Deserts as late as the 1950s.
Crash bandicoot is an extinct bandicoot, known from fossils located at the Riversleigh World Heritage Area in northeast Australia.
The Nullarbor barred bandicoot is an extinct species of bandicoot that was native to the arid Nullarbor Plain in southern Australia. It is also called the butterfly bandicoot for the dark brown patch on its rump, which resembles a butterfly. It was described in 2018 based on existing skins and osteological material within museum collections in Australia.
The quenda, also known as the western brown bandicoot, is a small marsupial species endemic to South Western Australia.
Perameles myosuros, the south-western barred bandicoot or marl, is a recently extinct species of bandicoot that was native to the southern parts of Western Australia. Initially described in 1841 it was later made a subspecies of the extant Perameles bougainville before being restored to species level in 2018, based on museum specimens. Of particular note was that the females were significantly larger than the males in P. myosuros, which is an unusual trait amongst mammals, whereas the sexes were the same size in P. bougainville.
