Zygomaturinae
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 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.

Neohelos
''Neohelos'' is an extinct diprotodontid marsupial, that lived from the early to middle-Miocene. There are four species assigned to this genus, ''Neohelos tirarensis'', the type species, ''N. stirtoni'', ''N. solus'' and ''N. davidridei''. ''N. davidridei'' is the most derived species of the genus, and its premolar morphology shows that it is structurally and ancestor of the genus ''Kolopsis''. All four species are from the Bullock Creek in the Northern Territory and Riversleigh of Australia. Description ''Neohelos'' is known from many specimens, assigned to all the species. ''N. tirarensis'' includes a partial skull, premaxillas, maxillas, teeth, and dentarys; ''N. solus'' is known from a maxilla and dentary; ''N. davidridei'' includes teeth and a maxilla fragment; and ''N. stirtoni'' is known from a mostly complete skull, a maxilla and a dentary.

Hulitherium
''Hulitherium tomasetti'' (meaning "Huli beast", after the Huli people) 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. Discovery While excavating a bank to widen the Pureni Mission airstrip in Wabag, New Guinea, to comply with new regulations, the Huli workers unearthed fossils in 1967. They reportedly were frightened by their discovery as bones in their culture are associated with the ancestors, so the material was somewhat damaged by their inquisitive prodding until they were brought to the attention of Father Bernard Tomasetti, who recognized the significance. Geologists Paul Williams and Michael Plane subsequently headed field expeditions in the area beginning in 1969 in search of more remains. Among the material was the partial skeleton of a diprotodontid, catalogue number CPC 25718, comprising: a well-pres ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Maokopia
''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 Poaceae () or Gramineae () is a large and nearly ubiquitous family of monocotyledonous flowering plants commonly known as grasses.

Diprotodontidae
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 ''Hulitherium tomasetti'' (meaning "Huli beast", after the Huli people) is an extinct zygomaturine marsupial from New Guinea during the Pleistocene.

Zygomaturus
''Zygomaturus'' is an extinct genus of giant marsupial belonging to the family Diprotodontidae which inhabited Australia from the Late Miocene to Late Pleistocene. Description It was a large animal, weighing 500 kg (1100 lbs) or over 700 kg (1544 lbs) and standing about 1.5 m (4.9 ft) tall and 2.5 m (8.2 ft) long. Palaeobiology In an analysis of remains from Cuddie Springs, the carbon isotope ratios suggests that it consumed both C3 and C4 plants, with a dental microwear texture indicative of browsing. Preserved remains suggest that ''Zygomaturus'' was widely distributed over Australia during the Pleistocene. Evolution and extinction The earliest members of the genus such as ''Zygomaturus gilli'' appeared during the Late Miocene, during the regional Waitean faunal stage. It is thought that the youngest species, ''Zygomaturus trilobus'' became extinct curing the latter half of the Late Pleistocene, with typical estimates being a ...

Silvabestius
''Silvabestius'' is an extinct genus of marsupial dating to the Early Miocene. They were grazing animals about the size of a modern sheep. This animal is known from two skulls found close together which have come to be known as the "Madonna and Child" fossils. Accessed May 14, 2008. ''Silvabestius'' was 1 metre in length, with a skull about 25 cm long. It was a herbivore which browsed on soft plant matter such as leaves and stems and lived in an environment that largely consisted of tropical rainforest. ''Silvabestius'' is in the family Diprotodontidae and is therefore related to the extinct giant marsupial '' Diprotodon

Marsupials
Marsupials are any members of the mammalian infraclass Marsupialia. All extant marsupials are endemic to Australasia, Wallacea and the Americas. A distinctive characteristic common to most of these species is that the young are carried in a pouch. Marsupials include opossums, Tasmanian devils, kangaroos, koalas, wombats, wallabies, bandicoots, and the extinct thylacine. Marsupials represent the clade originating from the last common ancestor of extant metatherians, the group containing all mammals more closely related to marsupials than to placentals. They give birth to relatively undeveloped young that often reside in a pouch located on their mothers' abdomen for a certain amount of time. Close to 70% of the 334 extant species occur on the Australian continent (the mainland, Tasmania, New Guinea and nearby islands). The remaining 30% are found in the Americas—primarily in South America, thirteen in Central America, and one species, the Virginia opossum, in North America, nor ...
