Ilaria is an extinct genus of marsupial of the family Ilariidae, dating from the Late Oligocene of South Australia. Its diet consisted of leaves.
Kollikodon is an extinct species of mammal, it is usually considered to be a member of Australosphenida and closely allied with monotremes, but is alternatively suggested to be a haramiyidan. 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, as was Steropodon. Kollikodon lived in the Late Cretaceous period, during the Cenomanian age.
Sarcophilus is a genus of carnivorous marsupial best known for its only living member, the Tasmanian devil. Sarcophilus is Latin - meaning 'flesh-loving'.
Barinya is a fossil genus from the marsupial family Dasyuridae, which contains the oldest known undoubted dasyurid.
Phascolonus was a genus of prehistoric Australian marsupials in the wombat family. The largest species, Phascolonus gigas, weighed as much as 200 kg. Phascolonus existed alongside an even larger marsupial, Diprotodon, which weighed as much as three tons and was distantly related to wombats. Both disappeared at the end of the Late Pleistocene in a Quaternary extinction event together with many other large Australian animals.
Zygomaturus is an extinct genus of giant marsupial belonging to the family Diprotodontidae which inhabited Australia from the Late Miocene to Late Pleistocene.
Hulitherium tomasetti is an extinct zygomaturine marsupial from New Guinea during the Pleistocene. The species name honours Berard Tomasetti, a Catholic priest in Papua New Guinea, who brought the fossils to the attention of experts.
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.
Nototherium is an extinct genus of diprotodontid marsupial from Australia and New Guinea. This mammal had hypsodont molars and weighed around 500kg. It was a relative of the larger Diprotodon and a distant kin to modern wombats.
Glaucodon is an extinct genus of marsupial from Australia.
Kolopsoides is an extinct genus of Zygomaturinae marsupial from the Otibanda Formation, Pliocene of Watut River, Papua New Guinea.
Raemeotherium is an extinct genus of diprotodont marsupial from the late Oligocene Namba Formation of South Australia. It was much smaller than other diprotodonts, approximately the size of a lamb, and comparatively gracile. It is usually placed within the Zygomaturinae, but because the upper third premolar is unknown doubt remains about its affinities.
Maokopia is an extinct genus of Zygomaturinae from the Late Pleistocene of Irian Jaya, New Guinea. It is known from a partial skull and was a comparatively small species of diprotodontid, weighing 100 kg. Murray (1992) suggested that it was most closely related to Hulitherium. The teeth indicate a diet of hard ferns and grasses that still grow in the alpine meadows of the area.
Plaisiodon is an extinct genus of Zygomaturinae from the late Miocene Alcoota Fossil Beds in the Northern Territory, Australia. Because of its robust skull it has been suggested that it consumed relatively hard or coarse vegetation.
The Diprotodontidae are an extinct family of large herbivorous marsupials, endemic to Australia and New Guinea during the Oligocene through Pleistocene periods from 28.4 million to 40,000 years ago. The family consisted of large quadrupedal terrestrial browsers, notably including the largest marsupial that ever lived, the rhino-sized Diprotodon. The group first appeared during the Late Oligocene, with representatives that were mostly sheep-sized, and substantially diversified beginning during the Late Miocene, reaching an apex of diversity during the Pliocene with seven genera, likely due to the increase of open forested landscapes. The last known members of the group including Diprotodon and Zygomaturus from mainland Australia, and Hulitherium and Maokopia from New Guinea became extinct during the Late Pleistocene around 40,000 years ago, after the arrival of humans to Australia-New Guinea.
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.
Meniscolophus is an extinct genus of Diprotodontia known from the early Pliocene of the Tirari Desert, South Australia.
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.
Kuterintja is an extinct genus of marsupial of the family Ilariidae. Only one species has been described, Kuterintja ngama, from Late Oligocene of Australia.
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 Zygomaturinae are an extinct subfamily of marsupials. The phylogeny and taxonomy of this clade is poorly understood and problematic. Zygomaturines are currently thought to be a subfamily within Diprotodontidae, rather than a distinct family.
