Vombatoidea
The Vombatiformes are one of the three suborders of the large marsupial order Diprotodontia. Seven of the nine known families within this suborder are extinct; only the families Phascolarctidae, with the koala, and Vombatidae, with three extant species of wombat, survive. Among the extinct families are the Diprotodontidae, which includes the rhinoceros sized ''Diprotodon'', believed to be the largest marsupials ever, as well as the "marsupial lions" Thylacoleonidae and "marsupial tapirs" Palorchestidae. "Vombatiformes" is neo-Latin for "wombat-shaped things", and took its name from its type family. The suborder Vombatiformes, with its closely related members and their compact body form, contrasts with the other two diprotodont suborders, the Macropodiformes: kangaroos, wallabies, and the quokka; and the Phalangeriformes: possums, including the gliders such as the wrist-winged gliders. The koala and wombats are believed by many biologists to share a common ancestor and to hav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Koala
The koala or, inaccurately, koala bear (''Phascolarctos cinereus''), is an arboreal herbivorous marsupial native to Australia. It is the only extant representative of the family Phascolarctidae and its closest living relatives are the wombats. The koala is found in coastal areas of the mainland's eastern and southern regions, inhabiting Queensland, New South Wales, Victoria, and South Australia. It is easily recognisable by its stout, tailless body and large head with round, fluffy ears and large, spoon-shaped nose. The koala has a body length of and weighs . Fur colour ranges from silver grey to chocolate brown. Koalas from the northern populations are typically smaller and lighter in colour than their counterparts further south. These populations possibly are separate subspecies, but this is disputed. Koalas typically inhabit open ''Eucalyptus'' woodland, as the leaves of these trees make up most of their diet. Because this eucalypt diet has limited nutritional and calor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lake Eyre
Lake Eyre ( ), officially known as Kati Thanda–Lake Eyre, is an endorheic lake in east-central Far North South Australia, some north of Adelaide. The shallow lake is the depocentre of the vast endorheic Lake Eyre basin, and contains the lowest natural point in Australia at approximately below sea level ( AHD), and on the rare occasions that it fills completely, is the largest lake in Australia covering an area up to . When the lake is full, it has the same salinity level as seawater, but becomes hypersaline as the lake dries up and the water evaporates. The lake was named in honour of Edward John Eyre, the first European to see it in 1840. The lake's official name was changed in December 2012 to combine the name "Lake Eyre" with the Aboriginal name, Kati Thanda. The native title over the lake and surrounding region is held by the Arabana people. Geography Kati Thanda–Lake Eyre is in the deserts of central Australia, in northern South Australia.

Cenozoic
The Cenozoic ( ; ) is Earth's current geological era, representing the last 66million years of Earth's history. It is characterised by the dominance of mammals, birds and flowering plants, a cooling and drying climate, and the current configuration of continents. It is the latest of three geological eras since complex life evolved, preceded by the Mesozoic and Paleozoic. It started with the Cretaceous–Paleogene extinction event, when many species, including the non-avian dinosaurs, became extinct in an event attributed by most experts to the impact of a large asteroid or other celestial body, the Chicxulub impactor. The Cenozoic is also known as the Age of Mammals because the terrestrial animals that dominated both hemispheres were mammalsthe eutherians (placentals) in the northern hemisphere and the metatherians (marsupials, now mainly restricted to Australia) in the southern hemisphere. The extinction of many groups allowed mammals and birds to greatly diversify so that l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wrist-winged Glider
The genus ''Petaurus'' () contains flying phalangers or wrist-winged gliders, a group of arboreal possums native to Australia, New Guinea, and surrounding islands. There are eight species: the sugar glider, savanna glider, Krefft's glider, squirrel glider, mahogany glider, northern glider, yellow-bellied glider and Biak glider. Flying phalangers are typically nocturnal, most being small (sometimes around 400 mm, counting the tail), and have folds of loose skin (patagia) running from the wrists to the ankles. They use the patagia to glide from tree to tree by jumping and holding out their limbs spread-eagle. They are able to glide for distances over 140 metres. Beside the distinctive skin folds, flying phalangers also have large, forward-facing eyes, short (though pointed) faces, and long flat tails which are used as rudders while gliding. All are omnivores, and eat tree sap, gum, nectar, pollen, and insects, along with manna and honeydew. Most flying phalangers appear ...

Phalangeriformes
Phalangeriformes is a paraphyletic suborder of about 70 species of small to medium-sized arboreal marsupials native to Australia, New Guinea, and Sulawesi. The species are commonly known as possums, gliders, and cuscus. The common name "possum" for various Phalangeriformes species derives from the creatures' resemblance to the opossums of the Americas (the term comes from Powhatan language ''aposoum'' "white animal", from Proto-Algonquian *''wa·p-aʔɬemwa'' "white dog"). However, although opossums are also marsupials, Australasian possums are more closely related to other Australasian marsupials such as kangaroos. Phalangeriformes are quadrupedal diprotodont marsupials with long tails. The smallest species, indeed the smallest diprotodont marsupial, is the Tasmanian pygmy possum, with an adult head-body length of and a weight of . The largest are the two species of bear cuscus, which may exceed . Phalangeriformes species are typically nocturnal and at least partially arbo ...

Quokka
The quokka (''Setonix brachyurus'', ) is a small macropod about the size of a domestic cat. It is the only member of the genus ''Setonix''. Like other marsupials in the macropod family (such as kangaroos and wallabies), the quokka is herbivorous and mainly nocturnal. Quokkas are found on some smaller islands off the coast of Western Australia, particularly Rottnest Island just off Perth and Bald Island near Albany. Isolated, scattered populations also exist in forest and coastal heath between Perth and Albany. A small colony inhabits a protected area of Two Peoples Bay Nature Reserve, where they co-exist with the critically endangered Gilbert's potoroo. Description A quokka weighs and is long with a tail, which is quite short for a macropod. It has a stocky build, well developed hind legs, rounded ears, and a short, broad head. Its musculoskeletal system was originally adapted for terrestrial bipedal saltation, but over its evolution, its system has been built for arb ...

Wallaby
A wallaby () is a small or middle-sized Macropodidae, macropod native to Australia and New Guinea, with introduced populations in New Zealand, Hawaii, the United Kingdom and other countries. They belong to the same Taxonomy (biology), taxonomic family as kangaroos and sometimes the same genus, but kangaroos are specifically categorised into the four largest species of the family. The term "wallaby" is an informal designation generally used for any macropod that is smaller than a kangaroo or a wallaroo that has not been designated otherwise. There are nine species (eight extant and one Extinction, extinct) of the brush wallaby (genus ''Notamacropus''). Their head and body length is and the tail is long. The 19 known species of Rock-wallaby, rock-wallabies (genus ''Petrogale'') live among rocks, usually near water; two species in this genus are endangered. The two living species of hare-wallabies (genus ''Lagorchestes''; two other species in this genus are extinct) are sma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kangaroo
Kangaroos are four marsupials from the family Macropodidae (macropods, meaning "large foot"). In common use the term is used to describe the largest species from this family, the red kangaroo, as well as the antilopine kangaroo, eastern grey kangaroo, and western grey kangaroo. Kangaroos are indigenous to Australia and New Guinea. The Australian government estimates that 42.8 million kangaroos lived within the commercial harvest areas of Australia in 2019, down from 53.2 million in 2013. As with the terms "wallaroo" and "wallaby", "kangaroo" refers to a paraphyletic grouping of species. All three terms refer to members of the same taxonomic family, Macropodidae, and are distinguished according to size. The largest species in the family are called "kangaroos" and the smallest are generally called "wallabies". The term "wallaroos" refers to species of an intermediate size. There are also the tree-kangaroos, another type of macropod, which inhabit the tropical ra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
