Crenadactylus
''Crenadactylus'', the clawless geckos, are named for their distinguishing feature, the absence of terminal claws on the digits. They are the only Australian members of Gekkonidae to lack claws, the endemic genus is also the smallest in size. Description Smaller geckos found in central and western Australia, the smallest of the Gekkota species found on the continent and notable for the absence of claws at the end of any the toes. An early osteological comparison to related taxa presented considerable and unusual variation, such as being clawless, but in particular the forked arrangement of phalangeal bones within the digits of the gecko. A genus, sometimes assigned to the Diplodactylidae family, whose tiny and superficially similar species have diverged in isolation at a range of habitats across a wide geographic area. Taxonomy The genus has been placed with the Diplodactylidae, a family allied to the Gekkota (geckos and limbless lizard species). This is a list of species r ...

Crenadactylus Occidentalis
''Crenadactylus occidentalis'', also called the western clawless gecko, is a species of gecko endemic to the western coast of Australia. Taxonomy ''Crenadactylus occidentalis'' was first described in a taxonomic revision in 2016 of rare and poorly known geckos of the genus ''Crenadactylus'', assembling evidence of greatly under-estimated speciation previously only recognised as subspecies of monotypic genus. One of four new species to emerge from molecular studies that had reported chromosomal distinctions that indicated the population's divergence around twenty to thirty million years ago. The holotype was collect by Brad Maryan and Robert Browne-Cooper during April in 1992 at Dirk Hartog Island. '' Crenadactylus ocellatus'', found in a wider distribution of Southwest Australia, has also been referred to as the western clawless gecko. Prior to the revision in 2016, the population had been identified as two 'forms' found at adjacent ranges in the western regions of Australia ...

Crenadactylus Pilbarensis
''Crenadactylus pilbarensis'' is a species of gecko found in the Pilbara region of Western Australia. They resemble other species of the genus ''Crenadactylus'', tiny clawless Australian geckos found across a large area of the continent, but has persisted as an ancient lineage in a region of the northwest. Taxonomy Unrecognised as a species before 2016, the first description was published in a revision of the genus that elevated the subspecific ranks of a single species and published this as one of three new species. The vernacular and specific epithet, ''pilbaraensis'', refers to the only region in which it is recorded, the Pilbara craton in the northwest of Australia. A common name for the species is Pilbara clawless gecko. Description The coloration is distinguished by their small size and contrasting light and dark stripes that appear along the length of the body. A large scale at the chin is characteristic of ''Crenadactylus pilbarensis''. Habitat and range ''Crenad ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crenadactylus Ocellatus
''Crenadactylus ocellatus'', also known as the southwestern clawless gecko or western clawless gecko, is the smallest species of nocturnal Gekkonidae (gecko) found in Australia. Endemic to Australia, it is distributed in the southwest of the country, and found on stony ground or in '' Triodia''-dominated deserts. It a ground-dwelling gecko; its habitat is leaf litter, rubbish piles, and beneath rocks. It is sometimes found in the lower parts of hummock grass. It is sometimes called the western clawless gecko, but that name is also reserved for ''Crenadactylus occidentalis''. Taxonomy The first description of the species was published by John Edward Gray in 1845, in a revision of specimens at the British Museum, placing his type in the genus ''Diplodactylus ''Diplodactylus'' is a genus of geckos of the family Diplodactylidae from Australia. They are sometimes called stone geckos or fat-tailed geckos. Member species are morphologically similar but genetically distinct. Spe ...

Crenadactylus Horni
''Crenadactylus horni'', the Central Uplands clawless gecko, is a species of gecko endemic to the central desert region of Australia. Taxonomy A species proposed by Arthur H. S. Lucas and Charles Frost, given the name ''Ebenavia horni'' to ally the taxon to a clawless gecko species found in Madagascar, basing their description on material collected on the Horn expedition to central Australia. The taxon was later placed as a subspecies of ''Crenadactylus ocellatus'', but re-elevated to species status in a revision of the genus that recognised seven distinguishable species. The type locality was identified as Charlotte Waters in the Northern Territory. The specific epithet ''horni'' is named by Lucas and Frost for the sponsor of the scientific expedition that provided the type specimen, the pastoralist William Austin Horn.

Diplodactylidae
The Diplodactylidae are a family in the suborder Gekkota (geckos), with over 150 species in 25 genera. These geckos occur in Australia, New Zealand, and New Caledonia. Diplodactylids are the most ecologically diverse and widespread family of geckos in both Australia and New Caledonia, and are the only family of geckos found in New Zealand. Three diplodactylid genera (''Oedura'', ''Rhacodactylus'', and ''Hoplodactylus'') have recently been split into multiple new genera. In previous classifications, the family Diplodactylidae is equivalent to the subfamily Diplodactylinae. Habitat Like other geckos, Diplodactylidae often live in warm areas that are around the temperature of . They mostly live in rain forests, up in the trees for protection. However, they are also found in cooler climates such as those found in southern New Zealand, where they have been found to be active in temperatures ranging from 1.4 to 31.9C. Reproduction Viviparity is notable as a trait unique to diploda ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 expansi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lizard Genera
Lizards are a widespread group of squamate reptiles, with over 7,000 species, ranging across all continents except Antarctica, as well as most oceanic island chains. The group is paraphyletic since it excludes the snakes and Amphisbaenia although some lizards are more closely related to these two excluded groups than they are to other lizards. Lizards range in size from chameleons and geckos a few centimeters long to the 3-meter-long Komodo dragon. Most lizards are quadrupedal, running with a strong side-to-side motion. Some lineages (known as " legless lizards"), have secondarily lost their legs, and have long snake-like bodies. Some such as the forest-dwelling ''Draco'' lizards are able to glide. They are often territorial, the males fighting off other males and signalling, often with bright colours, to attract mates and to intimidate rivals. Lizards are mainly carnivorous, often being sit-and-wait predators; many smaller species eat insects, while the Komodo eats mammals as ...

Endemic Fauna Of Australia
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
