Bettongini is a tribe of mammals. It contains two extant genera and one recently extinct one: [2]
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.
Kollikodon is an extinct species of mammal, considered to be an early monotreme. It is known only from an opalised dentary fragment, with one premolar and two molars in situ, as well as a referred maxillary fragment containing the last premolar and all four molars. The fossils were found in the Griman Creek Formation at Lightning Ridge, New South Wales, Australia. Kollikodon lived in the Late Cretaceous period, during the Cenomanian age. Several other monotremes are known from the Griman Creek Formation, including Dharragarra, Opalios, Parvopalus, Steropodon, and Stirtodon.
Steropodon is a genus of prehistoric platypus-like monotreme, or egg-laying mammal. It contains a single species, Steropodon galmani, that lived about 100.2–96.6 million years ago during the Cretaceous period, from early to middle Cenomanian. It is one of the oldest monotremes discovered, and is one of the oldest Australian mammal discoveries. Several other monotremes are known from the Griman Creek Formation, including Dharragarra, Kollikodon, Opalios, Parvopalus, and Stirtodon.
Timothy Fridtjof Flannery is an Australian mammalogist, palaeontologist, environmentalist, conservationist, explorer, author, science communicator, activist, and public scientist. He is especially known for his 1994 book The Future Eaters, on the natural history of Australasia, which was adapted for television in 2006, and his 2006 book The Weather Makers, about the effects of climate change in Australia.
The eastern bettong, also known as the southern or Tasmanian bettong, is a small, hopping, rat-like mammal native to grassy forests of southeastern Australia and Tasmania. A member of the rat-kangaroo family (Potoroidae), it is active at night and feeds on fungi and plant roots. Like most marsupials, it carries its young in a pouch. The eastern bettong is under pressure by introduced predators and habitat loss. The subspecies on mainland Australia is extinct, but populations of the Tasmanian subspecies have been reintroduced there.
The northern bettong is a small, endangered, gerbil-like mammal native to forests in northeast Australia. A member of the rat-kangaroo family (Potoroidae), it moves by hopping and lives in burrows, feeding at night on roots and fungi. It is also a marsupial and carries its young in a pouch. The northern bettong is threatened by habitat loss, and is now restricted to a few small areas.
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. 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.
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 the 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, furry, rat-like mammal native to Australia. Once common throughout the continent, it is now restricted to a few coastal islands. A member of the rat-kangaroo family (Potoroidae), it lives in burrows and is active at night when it forages for fungi, roots, and other plant matter. It is about the size of a rabbit and, like most marsupials, carries its young in a pouch.
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.
The Woodlark cuscus is a species of marsupial in the family Phalangeridae endemic to Papua New Guinea, specifically on Madau and Woodlark Island, a part of the Milne Bay Province of Papua New Guinea. It happens to be the largest mammal living on Woodlark Island but it is also found on the neighboring island of Alcester, 70 kilometers south of Woodlark Island.
Euryzygoma is an extinct genus of marsupial which inhabited humid eucalyptus forests in Queensland and New South Wales during the Pliocene of Australia. Euryzygoma is believed to have weighed around 500 kg, and differed from other diprotodonts in having unusual, flaring cheekbones that may have been used either for storing food or for sexual display. Euryzygoma is thought to be the ancestral genus from which Diprotodon evolved.
Pyramios is an extinct genus of diprotodont from the Miocene of Australia. It was very large, reaching a length of about 2.5 m and a height of about 1.5 m. Pyramios is estimated to have weighed 700 kg. It was comparable in size to its cousin Diprotodon, which is also in the family Diprotodontidae.
Euowenia is an extinct genus of Diprotodontia which existed from the Pliocene to the upper Pleistocene. Weighing around 500 kg, Euowenia is only known from three locations on mainland Australia, Chinchilla in Queensland, Menindee in New South Wales and the Tirari formation on the Warburton River in the Lake Eyre basin.
Ilaria is an extinct genus of marsupial of the family Ilariidae, dating from the Late Oligocene of South Australia. Its diet consisted of leaves.
Professor Michael Archer AM, FAA, Dist FRSN is an Australian paleontologist specialising in Australian vertebrates. He is a professor at the School of Biological, Earth & Environmental Sciences, University of New South Wales. His previous appointments include Director of the Australian Museum 1999–2004 and Dean of Science at the University of New South Wales 2004–2009.
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.
Bettongia moyesi is a fossil species of potoroid marsupial.
Teinolophidae is an extinct family of small mammals that are among the earliest known monotremes and were endemic to what would become Australia. Two genera have been described as belonging to this family: Teinolophos, and Stirtodon.
