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. However, although opossums are also marsupials, Australasian possums are more closely related to other Australasian marsupials such as kangaroos.
The aye-aye is a long-fingered lemur, a strepsirrhine primate native to Madagascar with rodent-like teeth that perpetually grow and a special thin middle finger that they can use to catch grubs and larvae out of tree trunks.
Petauridae is a family of possums containing 11 species: four species of trioks and striped possum, six species of wrist-winged glider, and Leadbeater's possum, which has only vestigial gliding membranes. Most of the wrist-winged gliders are native to Australia, whereas most of the striped possums to New Guinea, but some members of each group are found on both sides of the Torres Strait. Leadbeater's possum is endemic to Victoria, Australia.
The squirrel glider is a nocturnal gliding possum. The squirrel glider is one of the wrist-winged gliders of the genus Petaurus.
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.
Yalkaparidon is an extinct genus of Australian marsupials, first described in 1988 and known only from the Oligo-Miocene deposits of Riversleigh, northwestern Queensland, Australia.
The Daintree River is a river that rises in the Daintree Rainforest near Cape Tribulation in Far North Queensland, Australia. The river is located about 100 kilometres (62 mi) northwest of Cairns in the UNESCO World Heritage–listed Wet Tropics of Queensland. The area is now primarily a tourist attraction.
The mahogany glider is an endangered gliding possum native to a small region of coastal Queensland in Australia.
The yellow-bellied glider, also known as the fluffy glider, is an arboreal and nocturnal gliding possum that lives in native eucalypt forests in eastern Australia, from northern Queensland south to Victoria.
The great-tailed triok is a species of marsupial in the family Petauridae. It is found in West Papua and Papua New Guinea. Its natural habitat is subtropical or tropical dry forests.
Dactylopsila is a genus of marsupials in the family Petauridae, native to New Guinea, the Cape York peninsula of Australia, and other close islands. Members of this genus are known as trioks or striped possums, though the latter name is usually used for D. trivirgata.
Tate's triok, also known as the Fergusson Island striped possum, is a species of marsupial in the family Petauridae. It is endemic to Papua New Guinea. Its natural habitat is subtropical or tropical dry forests.
The northern glider is a species of marsupial in the family Petauridae. It is endemic to Papua New Guinea, becoming known to science in 1981 after being discovered in the Torricelli Mountains. This species has been found in primary, mid-montane tropical moist forests. It is also known from rural gardens close to forest. The northern glider is Critically Endangered because its occurrence is less than 100 km2, all individuals are located within a single area, and a continuing decline of its habitat quality due to deforestation and human encroachment. They also face a major threat from hunting.
Petauroidea is a superfamily of marsupials from Australia and New Guinea. It is part of the suborder Phalangeriformes within the order Diprotodontia, which also includes, among others, wombats, kangaroos, cuscuses. The superfamily Phalangeroidea, including cuscuses and brushtail possums and pygmy possums, is the immediate sister group of the Petauroidea. The earliest fossils from this superfamily are from the Oligocene of the Geilston Bay fossil site in Tasmania.
Apatemys is a member of the family Apatemyidae, an extinct group of small and insectivorous placental mammals that lived in the Paleogene of North America, India, and Europe. While the number of genera and species is less agreed upon, it has been determined that two apatemyid genera, Apatemys and Sinclairella, existed sequentially during the Eocene in North America. The genus Apatemys, living as far back as 50.3 million years ago (mya), existed through part of the Wasatchian and persisted through the Duchesnean, and Sinclairella followed, existing from the Duchesnean through the Arikareean. Examinations of specimens belonging to the genus Apatemys suggest adaptations characteristic of arboreal mammals.
