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.
The Australian owlet-nightjar is a nocturnal bird found in open woodland across Australia and in southern New Guinea. It is colloquially known as the moth owl. It is the most common of the owlet-nightjars, and the best known of this secretive family. It is the most common nocturnal bird in Australia, and despite suffering from predation and competition by introduced species it is not considered threatened.
The ghost bat is a flying mammal found in northern Australia. The species is the only Australian bat that preys on large vertebrates – birds, reptiles and other mammals – which they detect using acute sight and hearing, combined with echolocation, while waiting in ambush at a perch. The wing membrane and bare skin is pale in colour, their fur is light or dark grey over the back and paler at the front. The species has a prominent and simple nose-leaf, their large ears are elongated and joined at lower half, and the eyes are also large and dark in colour. The first description of the species was published in 1880, its recorded range has significantly contracted since that time.
Megadermatidae, or false vampire bats, are a family of bats found from central Africa, eastwards through southern Asia, and into Australia. They are relatively large bats, ranging from 6.5 cm to 14 cm in head-body length. They have large eyes, very large ears and a prominent nose-leaf. They have a wide membrane between the hind legs, or uropatagium, but no tail. Many species are a drab brown in color, but some are white, bluish-grey or even olive-green, helping to camouflage them against their preferred roosting environments. They are primarily insectivorous, but will also eat a wide range of small vertebrates.
The orange leaf-nosed bat is a bat in the family Hipposideridae. It is the only living species in the genus Rhinonicteris which is endemic to Australia, occurring in the far north and north-west of the continent. They roost in caves, eat moths, and are sensitive to human intrusion.
The Hipposideridae are a family of bats commonly known as the Old World leaf-nosed bats. While it has often been seen as a subfamily, Hipposiderinae, of the family Rhinolophidae, it is now more generally classified as its own family. Nevertheless, it is most closely related to Rhinolophidae within the suborder Yinpterochiroptera.
Brachipposideros is an extinct genus of leaf-nosed bats known from Riversleigh, north-western Queensland, Australia and the Languedoc-Roussillon Region, France. The fossils date to the late Oligocene to early Miocene.
Naraboryctes philcreaseri is a fossil species of marsupial found at early Miocene deposits of Boodjamulla National Park of Riversleigh area, northwestern Queensland, Australia.
Macroderma is a genus of microbats, present in the fossil record and as one extant species. They have existed in Australia since the early Miocene.
Rhinonicteris tedfordi is an extinct species of microbat, of the order Chiroptera, known from fossil material found in Australia.
Riversleigh fauna is the collective term for any species of animal identified in fossil sites located in the Riversleigh World Heritage Area.
Brevipalatus mcculloughi is a species of bat that existed in the early Miocene. It was discovered at a fossil deposit of the Riversleigh World Heritage Area.
Xenorhinos halli is a species of bat that existed in the early Miocene. It was discovered at a fossil deposit of the Riversleigh World Heritage Area in the north of Australia.
Petramops creaseri is a species of molossid bat discovered in Miocene fossil deposits at the Riversleigh sites.
Riversleigha williamsi is a species of hipposiderid bat discovered in fossil deposits located the Riversleigh World Heritage Area in the north of Australia.
Hipposideros bernardsigei is a hipposiderid species of bat known by fossil specimens, one of the many new taxa of microchiropterans discovered in the Riversleigh World Heritage Area.
Macroderma koppa is a species of bat known from fossil material found in Australia, one of the larger carnivorous megadermatid family of the order Chiroptera. They resembled the modern species Macroderma gigas, known as a false vampire or ghost bat, and also preyed on vertebrates such as small mammals, reptiles and bird, and amphibian species, whose butchered remains were found beneath their feeding roosts.
Macroderma godthelpi is a species of bat known from fossil material found in Australia, one of the larger carnivorous megadermatid family of the order Chiroptera. They resembled the modern species Macroderma gigas, known as a false vampire or ghost bat, although significantly smaller than any other species of Macroderma.
Hipposideros winsburyorum is a hipposiderid species of bat known by fossil specimens, one of the many new taxa of chiropterans discovered in the Riversleigh World Heritage Area. The species existed during the Pliocene.
Liyamayi dayi is a mammal species of the Thylacomyidae family known from fossils located at the Riversleigh World Heritage Area in northeast Australia. The discovery of the specimens was identified as deposited around fifteen million years ago, revising the earliest record of this peramelemorphian lineage from those of species that existed around ten million years later.
