Megadermatidae
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, though ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ghost Bat
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 ...

The heart-nosed bat (''Cardioderma cor'') is a species of bat in the family Megadermatidae.

In the hierarchy of biological classification, genus com ... ''Cardioderma''. It is found in eastern Sudan, north Tanzania, and south Zambia. In an experiment conducted in 2017, it was concluded that heart-nosed bats emit vocalizations or "sing" as a way to establish their foraging areas and actively defend these territories from other bats of the same species. Habitat The heart-nosed bat typically occupies areas that are in dry lowlands, coastal strips, and river valleys. Places of interest that the bats tend to gather in the daylight hours are abandoned buildings, dry caves, or baobab trees. They are also found living no higher than 940 meters or 3094 feet ...

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.

Oligocene
The Oligocene ( ) is a geologic epoch of the Paleogene Period and extends from about 33.9 million to 23 million years before the present ( to ). As with other older geologic periods, the rock beds that define the epoch are well identified but the exact dates of the start and end of the epoch are slightly uncertain. The name Oligocene was coined in 1854 by the German paleontologist Heinrich Ernst Beyrich from his studies of marine beds in Belgium and Germany. The name comes from the Ancient Greek (''olígos'', "few") and (''kainós'', "new"), and refers to the sparsity of extant forms of molluscs. The Oligocene is preceded by the Eocene Epoch and is followed by the Miocene Epoch. The Oligocene is the third and final epoch of the Paleogene Period. The Oligocene is often considered an important time of transition, a link between the archaic world of the tropical Eocene and the more modern ecosystems of the Miocene. Major changes during the Oligocene included a global expansion o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
