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] |
Gecko
Geckos are small, mostly carnivorous lizards that have a wide distribution, found on every continent except Antarctica. Belonging to the infraorder Gekkota, geckos are found in warm climates throughout the world. They range from . Geckos are unique among lizards for their vocalisations, which differ from species to species. Most geckos in the family Gekkonidae use chirping or clicking sounds in their social interactions. Tokay geckos (''Gekko gecko'') are known for their loud mating calls, and some other species are capable of making hissing noises when alarmed or threatened. They are the most species-rich group of lizards, with about 1,500 different species worldwide. All geckos, except species in the family Eublepharidae lack eyelids; instead, the outer surface of the eyeball has a transparent membrane, the cornea. They have a fixed lens within each iris that enlarges in darkness to let in more light. Since they cannot blink, species without eyelids generally ...

Pilbara
The Pilbara () is a large, dry, thinly populated region in the north of Western Australia. It is known for its Aboriginal peoples; its ancient landscapes; the red earth; and its vast mineral deposits, in particular iron ore. It is also a global biodiversity hotspot for subterranean fauna. Definitions of the Pilbara region At least two important but differing definitions of "the Pilbara" region exist. Administratively it is one of the nine regions of Western Australia defined by the '' Regional Development Commissions Act 1993''; the term also refers to the Pilbara shrublands bioregion (which differs in extent) under the Interim Biogeographic Regionalisation for Australia (IBRA). General The Pilbara region, as defined by the Regional Development Commissions Act 1993 and administered for economic development purposes by the Pilbara Development Commission, has an estimated population of 61,688 , and covers an area of . It contains some of Earth's oldest rock formati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Western Australia
Western Australia (commonly abbreviated as WA) is a state of Australia occupying the western percent of the land area of Australia excluding external territories. It is bounded by the Indian Ocean to the north and west, the Southern Ocean to the south, the Northern Territory to the north-east, and South Australia to the south-east. Western Australia is Australia's largest state, with a total land area of . It is the List of country subdivisions by area, second-largest country subdivision in the world, surpassed only by Russia's Sakha, Sakha Republic. the state has 2.76 million inhabitants percent of the national total. The vast majority (92 percent) live in the South-West Land Division, south-west corner; 79 percent of the population lives in the Perth area, leaving the remainder of the state sparsely populated. The first Europeans to visit Western Australia belonged to the Dutch Dirk Hartog expedition, who visited the Western Australian coast in 1616. The first pe ...

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 ...

Pilbara Craton
The Pilbara Craton is an old and stable part of the continental lithosphere located in the Pilbara region of Western Australia. The Pilbara Craton is one of only two pristine Archaean 3.6–2.7 Ga (billion years ago) crusts identified on the Earth, along with the Kaapvaal Craton in South Africa. Both locations may have once been part of the Vaalbara supercontinent or the continent of Ur. The eastern portion is called the Eastern Pilbara Craton. Evidence of earliest life In May 2017, evidence of the earliest known life on land may have been found in 3.48-billion-year-old geyserite and other related mineral deposits (often found around hot springs and geysers) uncovered in the Dresser Formation in Pilbara Craton. The earliest ''direct'' evidence of life on Earth may be fossils of microorganisms permineralized in 3.465-billion-year-old Australian Apex chert rocks. However, the evidence for the biogenicity of these microstructures has been thoroughly debated. Origina ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Triodia (plant)
''Triodia'' is a large genus of hummock-forming bunchgrass endemic to Australia. They are known by the common name spinifex, although they are not a part of the coastal genus '' Spinifex''. Many of the soft-leaved members of this species were formerly included in the genus ''Plectrachne''. It is known as ''tjanpi'' in central Australia, and is used for basket weaving by the women of various Aboriginal Australian peoples. A multiaccess key (SpiKey) is available as a free application for identifying the ''Triodia'' of the Pilbara (28 species and one hybrid). Description ''Triodia'' is a perennial Australian tussock grass that grows in arid regions. Its leaves (30–40 centimetres long) are subulate ( awl-shaped, with a tapering point). The leaf tips, that are high in silica, can break off in the skin, leading to infections. Uses Spinifex has traditionally had many uses for Aboriginal Australians. The seeds were collected and ground to make seedcakes. Spinifex resin wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Burrup Peninsula
Murujuga, formerly known as Dampier Island and today usually known as the Burrup Peninsula, is in the Dampier Archipelago, in the Pilbara region of Western Australia, containing the town of Dampier. The Dampier Rock Art Precinct, which covers the entire archipelago, is the subject of ongoing political debate due to historical and proposed industrial development. The Murujuga National Park lies within Burrup, and contains within it the world's largest collection of ancient rock art. The region is sometimes confused with the Dampier Peninsula, to the north-east. History The traditional owners, the Indigenous people of the Burrup Peninsula, are an Aboriginal nation known as the Yaburara (Jaburara) people. In Ngayarda languages, including that of the Aboriginal people of the peninsula, the Jaburara (or Yaburara) people, ''murujuga'' meant "hip bone sticking out". Between February and May 1869 a great number of Yaburara people were killed in an incident known as the Flying Foa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dolphin Island (Western Australia)
Dolphin Island is an island situated in the Dampier Archipelago in the Pilbara region of Western Australia. Visitors are able to camp within of the high water mark on all of the beaches on the island except for the south eastern side. The island is designated as a B Class Nature Reserve (34944) and has a total area of . It is the second largest island of the archipelago after Enderby Island but it is the highest in the archipelago rising to above sea level. The island is composed of precambrian volcanic and granitic rocks with some outcrops of archaen granite and granite gneiss which are over 2400 Ma in age. The island is separated from the Burrup Peninsula by a major valley system formed by a regional fracture. Indigenous Australians Indigenous Australians or Australian First Nations are people with familial heritage from, and membership in, the ethnic groups that lived in Australia before British colonisation. They consist of two distinct groups: the Aboriginal p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Karlamilyi National Park
Karlamilyi National Park lies in the Pilbara region of Western Australia, northeast of Newman and north-northeast of Perth. Proclaimed an A Class Reserve on 13 April 1977, it is the largest national park in Western Australia. The park was initially listed on the Register of the National Estate in 1978 as Rudall River National Park, and was noted as "significant for maintaining ongoing geomorphic and ecological processes within a tropical desert environment. It contains an entire landscape sequence which includes extensive dune fields, table lands, an entire river/creek system, alluvial formations, saline lakes and palaeodrainage lines". The name of the park was changed in 2008 to Karlamilyi National Park to acknowledge the traditional owners of the area. The park's original name was derived from the Rudall River, named by Frank Hann who was one of the first Europeans to explore the area. He named the river after another explorer and surveyor, William Frederick Rudall. The ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reptiles Described In 2016
Reptiles, as most commonly defined are the animals in the class Reptilia ( ), a paraphyletic grouping comprising all sauropsids except birds. Living reptiles comprise turtles, crocodilians, squamates ( lizards and snakes) and rhynchocephalians (tuatara). As of March 2022, the Reptile Database includes about 11,700 species. In the traditional Linnaean classification system, birds are considered a separate class to reptiles. However, crocodilians are more closely related to birds than they are to other living reptiles, and so modern cladistic classification systems include birds within Reptilia, redefining the term as a clade. Other cladistic definitions abandon the term reptile altogether in favor of the clade Sauropsida, which refers to all amniotes more closely related to modern reptiles than to mammals. The study of the traditional reptile orders, historically combined with that of modern amphibians, is called herpetology. The earliest known proto-reptiles originated ...

Taxa Named By Paul Doughty
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in '' Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
