Horseshoe bats are bats in the family Rhinolophidae. In addition to the single living genus, Rhinolophus, which has about 106 species, the extinct genus Palaeonycteris has been recognized. Horseshoe bats are closely related to the Old World leaf-nosed bats, family Hipposideridae, which have sometimes been included in Rhinolophidae. The horseshoe bats are divided into six subgenera and many species groups. The most recent common ancestor of all horseshoe bats lived 34–40 million years ago, though it is unclear where the geographic roots of the family are, and attempts to determine its biogeography have been indecisive. Their taxonomy is complex, as genetic evidence shows the likely existence of many cryptic species, as well as species recognized as distinct that may have little genetic divergence from previously recognized taxa. They are found in the Old World, mostly in tropical or subtropical areas, including Africa, Asia, Europe, and Oceania.
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 ghost bat is a species of bat 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.
Hipposideros is one of the most diverse genera of bats, with more than 70 species. They are collectively called roundleaf bats after the shape of their nasal ornament. It is the type genus of the family Hipposideridae. It is divided into species groups based on morphology.
The chocolate wattled bat is a bat in the family Vespertilionidae. It is found only in Australia, including the island Tasmania, and widespread in southern regions. It is known to reside from sea level to at least 1,570 metres (5,150 ft) in Victoria.
The Indian roundleaf bat, also known as the large Ceylon leaf-nosed bat or Kelaart's leaf‐nosed bat is a species of bat in the family Hipposideridae. It is endemic to the Indian subcontinent, with marginal populations also detected in Southeast Asia. Its natural habitats are subtropical or tropical dry forests and caves. The bat has three subspecies that occur in India, Sri Lanka, and Myanmar. The Indian subspecies, H. l. indus, is smaller than the ones found in Sri Lanka and Myanmar, although there are no other characteristics that differentiate the subspecies.
The fawn leaf-nosed bat is a species of bat in the family Hipposideridae found in Australia, Indonesia, Malaysia, the Philippines and Vanuatu.
Schneider's leaf-nosed bat or Schneider's roundleaf bat is a species of bat in the family Hipposideridae. It is endemic to South Asia. Its natural habitats are subtropical or tropical dry forests, caves, and urban areas.
The orange leaf-nosed bat is a bat in the family Rhinonycteridae. 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.
Rhinonicteris is a genus of leaf-nosed microbats, represented by fossil taxa found at Riverleigh in Queensland and the extant species Rhinonicteris aurantia, which occurs in the north and west of the Australian continent.
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.
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.
Rhinonycteridae is a family of bats, within to the suborder Yinpterochiroptera. The type species, the orange nose-leafed species group Rhinonicteris aurantia, is found across the north of 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.
Riversleigha williamsi is a species of hipposiderid bat discovered in fossil deposits located the Riversleigh World Heritage Area in the north of Australia.
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.
