Macroderma Godthelpi
''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''. Taxonomy The description of ''Macroderma godthelpi'' was published in 1985 by the palaeontologist Suzanne Hand, separating Miocene fossil material discovered at the Riversleigh World Heritage Area as a new species of '' Macroderma''. The type material was selected from Gag site at Riversleigh, which were examined with other specimens obtained at a nearby named as the Microsite. The holotype is part of a right maxillary, still retaining several of the bat's teeth. The specific epithet honour a fellow researcher of the author, Henk Godthelp, who had noticed the first evidence of the fossil deposits containing the diverse and numerous bats that would ...

Megadermatid
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. Description False vampire bats are relatively large, with combined head and body lengths that range from . Their forearm lengths range from . They all lack tails. The ghost bat is the largest member of the family. All the species have very large ears with divided tragi. They have long nose-leaves. All species are similar in that they lack upper incisors, thoug ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chiroptera
Bats are mammals of the Order (biology), order Chiroptera.''cheir'', "hand" and πτερόν''pteron'', "wing". With their forelimbs adapted as wings, they are the only mammals capable of true and sustained flight. Bats are more agile in flight than most birds, Bat flight, flying with their very long spread-out digits covered with a thin skin, membrane or patagium. The smallest bat, and arguably the smallest extant mammal, is Kitti's hog-nosed bat, which is in length, across the wings and in mass. The largest bats are the Flying fox#Physical characteristics, flying foxes, with the giant golden-crowned flying fox, ''Acerodon jubatus'', reaching a weight of and having a wingspan of . The second largest order of mammals after rodents, bats comprise about 20% of all classified mammal species worldwide, with over 1,400 species. These were traditionally divided into two suborders: the largely fruit-eating megabats, and the Animal echolocation, echolocating microbats. But more r ...

Macroderma Gigas
The ghost bat (''Macroderma gigas'') 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. Taxonomy A species of '' Macroderma'', one of several genera in the family Megadermatidae (false vampires). The family all have large eyes, a nose-leaf and tragus, long ears joined at the base, and are also found in southern Asia and central Africa. The description was published ...

Macroderma (bat)
''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. Taxonomy The description to the genus was published in a revision of chiropterans by Gerrit Smith Miller Jr. in 1906, separating the type species from it placement in the genus ''Megaderma''. The taxonomic placement is to family Megadermatidae of the suborder Microchiroptera. The name ''Macroderma'' combines the Greek words ''macros'' (large) and ''derma'' (skin), due to the large size of their partially conjoined ears. * ''Macroderma gigas'' Dobson, 1880 the only living species, a large predatory carnivore referred to as the Australian false vampyre or ghost bat * ''Macroderma godthelpi'', a fossil taxon describing the earliest and smallest species * '' Macroderma koppa'' Hand, Dawson & Augee, 1988. a fossil species that existed in the Pliocene epoch. * '' Macroderma malugara'' S.

Riversleigh World Heritage Area
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 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 fossils at Riversleigh are unusual because they are found in soft freshwater limestone which has not been compacted. This means the animal remains retain their three-dimensional structure, rather than being partially crushed like in most fossil sites. The area is locat ...

Miocene
The Miocene ( ) is the first geological epoch of the Neogene Period and extends from about (Ma). The Miocene was named by Scottish geologist Charles Lyell; the name comes from the Greek words (', "less") and (', "new") and means "less recent" because it has 18% fewer modern marine invertebrates than the Pliocene has. The Miocene is preceded by the Oligocene and is followed by the Pliocene. As Earth went from the Oligocene through the Miocene and into the Pliocene, the climate slowly cooled towards a series of ice ages. The Miocene boundaries are not marked by a single distinct global event but consist rather of regionally defined boundaries between the warmer Oligocene and the cooler Pliocene Epoch. During the Early Miocene, the Arabian Peninsula collided with Eurasia, severing the connection between the Mediterranean and Indian Ocean, and allowing a faunal interchange to occur between Eurasia and Africa, including the dispersal of proboscideans into Eurasia.

Karst
Karst is a topography formed from the dissolution of soluble rocks such as limestone, dolomite, and gypsum. It is characterized by underground drainage systems with sinkholes and caves. It has also been documented for more weathering-resistant rocks, such as quartzite, given the right conditions. Subterranean drainage may limit surface water, with few to no rivers or lakes. However, in regions where the dissolved bedrock is covered (perhaps by debris) or confined by one or more superimposed non-soluble rock strata, distinctive karst features may occur only at subsurface levels and can be totally missing above ground. The study of ''paleokarst'' (buried karst in the stratigraphic column) is important in petroleum geology because as much as 50% of the world's hydrocarbon reserves are hosted in carbonate rock, and much of this is found in porous karst systems. Etymology The English word ''karst'' was borrowed from German in the late 19th century, which entered German much earlier ...

Riversleigh Fauna
Riversleigh fauna is the collective term for any species of animal identified in fossil sites located in the Riversleigh World Heritage Area. Faunal zones The presence of the Riversleigh in the Oligo-Miocene has been exceptionally well preserved throughout a number of time periods. These has been classified by four "faunal zones", and may be summarised as, * Faunal Zone A (FZA): late Oligocene, a period 23.03–28.4 million years before present * Faunal Zone B (FZB): early Miocene, 15.97-23.03 myr * Faunal Zone C (FZC): middle Miocene, 11.608-15.97 myr * Faunal Zone D (FZD): late Miocene, 5.332-11.608 myr More recent fossil specimens has also been coded to the period of deposition, * Pliocene (PLIO), a period 2.588-5.332 myr * Pleistocene (PLEIS), 0.0117-2.588 myr * Holocene, noted as (HOLO) to indicate the period dated as following the Pleistocene, from the present day to 11,700 years ago.

Cave
A cave or cavern is a natural void in the ground, specifically a space large enough for a human to enter. Caves often form by the weathering of rock and often extend deep underground. The word ''cave'' can refer to smaller openings such as sea caves, rock shelters, and grottos, that extend a relatively short distance into the rock and they are called ''exogene'' caves. Caves which extend further underground than the opening is wide are called ''endogene'' caves. Speleology is the science of exploration and study of all aspects of caves and the cave environment. Visiting or exploring caves for recreation may be called ''caving'', ''potholing'', or ''spelunking''. Formation types The formation and development of caves is known as ''speleogenesis''; it can occur over the course of millions of years. Caves can range widely in size, and are formed by various geological processes. These may involve a combination of chemical processes, erosion by water, tectonic forces, microorgani ...
