Tiliqua pusilla is an extinct species of the extant genus Tiliqua , the blue-tongued skinks. It lived during the Miocene period. It was described in 1992 based on dentary fossils from Riversleigh Station, Queensland. [1] [2]
The order Peramelemorphia includes the bandicoots and bilbies. All members of the order are endemic to Australia-New Guinea and most have the characteristic bandicoot shape: a plump, arch-backed body with a long, delicately tapering snout, very large upright ears, relatively long, thin legs, and a thin tail. Their size varies from about 140 grams up to 4 kilograms, but most species are about one kilogram.
Thylacinidae is an extinct family of carnivorous marsupials from the order Dasyuromorphia. The only species to survive into modern times was the thylacine, which became extinct in 1936.
Egernia is a genus of skinks that occurs in Australia. These skinks are ecologically diverse omnivores that inhabit a wide range of habitats. However, in the loose delimitation the genus is not monophyletic but an evolutionary grade, as has long been suspected due to its lack of characteristic apomorphies.
The pink-tongued skink is a species of lizard in the family Scincidae. It is endemic to Australia, where it is also called commonly the pink-tongued lizard. As suggested by these common names, its distinguishing characteristic is a pink tongue as opposed to the blue tongue of lizards of the closely related genus Tiliqua.
Riversleigh World Heritage Area is Australia's most famous fossil location, recognised for the series of well preserved fossils deposited from the Late Oligocene to more recent geological periods. The fossiliferous limestone system is located near the Gregory River in the north-west of Queensland, an environment that was once a very wet rainforest that became more arid as the Gondwanan land masses separated and the Australian continent moved north. The approximately 100 square kilometres (39 sq mi) area has fossil remains of ancient mammals, birds, and reptiles of the Oligocene and Miocene ages, many of which were discovered and are only known from the Riversleigh area; the species that have occurred there are known as the Riversleigh fauna.
Blue-tongued skinks comprise the Australasian genus Tiliqua, which contains some of the largest members of the skink family (Scincidae). They are commonly called blue-tongued lizards or simply blue-tongues or blueys in Australia or panana in Indonesia. As suggested by these common names, a prominent characteristic of the genus is a large blue tongue that can be bared as bluff-warning to potential enemies. The type of predator/threat that is near will determine the intensity of colour present in the tongue. The tongue can also deform itself and produce a thick mucus in order to catch prey. They are relatively shy in comparison with other lizards, and also significantly slower due to their shorter legs.
Yurlunggur is a genus of fossil snake in the extinct family Madtsoiidae containing the species Yurlunggur camfieldensis known from the Oligocene and Miocene of Australia.
Tiliqua rugosa, most commonly known as the shingleback skink or bobtail lizard, is a short-tailed, slow-moving species of blue-tongued skink endemic to Australia. It is commonly known as the shingleback or sleepy lizard. Three of its four recognised subspecies are found in Western Australia, where the bobtail name is most frequently used. The fourth subspecies, T. rugosa asper, is the only one native to eastern Australia, where it goes by the common name of the eastern shingleback.
The Tiliqua scincoides scincoides, or eastern blue-tongued lizard, is native to Australia. It is unique due to its blue tongue, which can be used to warn off predators. In addition to flashing its blue tongue, the skink hisses and puffs up its chest to assert dominance and appear bigger when in the presence of its predators such as large snakes and birds. The eastern blue tongue is ovoviviparous and precocial, meaning that its young are more developed and advanced at their time of birth. The Tiliqua scincoides scincoides is not venomous to humans and can be found in suburban and urban areas, specifically in house gardens.
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 Adelaide pygmy blue-tongue skink or pygmy bluetongue is a species of skink, a lizard in the family Scincidae. The species was previously thought to be extinct and only rediscovered in 1992. Known locations of the species extend from Kapunda in the Light River valley, about 77 kilometres (48 mi) north east of Adelaide, northwards to Peterborough, about 254 kilometres (158 mi) north of Adelaide.
Emuarius is an extinct genus of casuariiform flightless bird from Australia that lived during the early Miocene and late Oligocene. It is one of two known genera of emu. There are two known species in the genus, Emuarius gidju and Emuarius guljaruba. The birds in this genus are known as emuwaries. This name comes from a combination of emu and cassowary. This is due to its cassowary-like skull and femur and emu-like lower leg and foot. Because of these similarities it is phylogenetically placed between cassowaries and emus.
Ngamalacinus timmulvaneyi lived during the early Miocene and has been found in Riversleigh.
Ganguroo is a genus of fossil macropods found at Riversleigh in Australia, material dating from the Middle to Late Miocene Epoch. The type species of the genus is Ganguroo bilamina, published in 1997. Two recently described species, Ganguroo bites and Ganguroo robustiter, have also been placed in this genus.
Malleodectes is an extinct genus of unusual marsupial, first discovered in 2011 at Riversleigh, Queensland, Australia.
The Indonesian blue-tongued skink is a lizard in the family Scincidae. It is a close relative of the Eastern blue-tongued lizard. They are endemic to the island of New Guinea and other various surrounding islands. They are found typically in the rainforest, and in captivity, require high humidity. As opposed to Tiliqua scincoides, they are fairly lean. They're also accompanied by long tails.
Tiliqua scincoides is a species of skink. It is native to Australia as well Tanimbar Island.
The Centralian blue-tongued skink or Centralian blue-tongue is a species of skink, occurring predominantly in the far north-west corner of New South Wales, Australia. It is one of six species belonging to the genus Tiliqua; the blue-tongued skinks and the shinglebacks.
Egernia stokesii is a gregarious species of lizard of the Scincidae family. This diurnal species is endemic to Australia, and is also known as the Gidgee skink, spiny-tailed skink, Stokes's skink and Stokes's egernia. The species forms stable, long-term social aggregations, much like the social groups seen in mammalian and avian species. This characteristic is rarely found in the Squamata order, but is widespread within the Australian subfamily of Egerniinae skinks. Populations of E. stokesii are widely distributed, but fragmented, and occur in semi-arid environments. There are three recognised subspecies. The conservation status for the species is listed as least concern, however, one subspecies is listed as endangered.
Riversleigh fauna is the collective term for any species of animal identified in fossil sites located in the Riversleigh World Heritage Area.
