Salisbury Island (Western Australia)
Salisbury Island is located in the Recherche Archipelago off the south coast of Western Australia.Gazetteer of Australia (1996). Belconnen, ACT: Australian Surveying and Land Information Group. The island occupies an area of , the third largest island in the Recherche Archipelago. It is situated approximately east of Esperance and off the coast near the edge of the continental shelf, making it one of the southernmost islands in the archipelago. The island is formed from a massive limestone scarp that sits atop a granite dome. Many caves are found throughout the island both above and below water. Indigenous Australians are thought to have inhabited the island up to 18,000 years ago. Archeologists have found ancient artefacts on the island such as stone blades, lizard traps, axe heads, grinding stones and granite watering holes. The objects are believed to be 5,000 to 18,000 years old from a time when many of the islands were joined to the mainland. ''Rodondo'' was thought ...

Recherche Archipelago
The Archipelago of the Recherche, known locally as the Bay of Isles, is a group of 105 islands, and over 1200 "obstacles to shipping", off the south coast of Western Australia. The islands stretch from east to west and to off-shore encompassing an area of approximately . The western group is near Esperance and the eastern group at Israelite Bay. They are located in coastal waters, part of which is designated the Recherche Archipelago Nature Reserve. History Pre-European Recherche Archipelago exhibits evidence of human occupation dated to 13,000 years ago. Archeologists have found ancient artefacts on Salisbury Island, a massive limestone remnant sitting on a granite dome offshore, that included stone blades, lizard traps, axe heads, grinding stones and granite watering holes. The objects are believed to extend up to 13,000 years before present, from a time of lower sea levels when many of the islands were joined to the mainland.

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 ...

Rattus Fuscipes
The bush rat or Australian bush rat (''Rattus fuscipes'') is a small Australian nocturnal animal. It is an omnivore and one of the most common indigenous species of rat on the continent, found in many heathland areas of Victoria and New South Wales. Taxonomy The description of the species by G. R. Waterhouse was published in the second part of the series '' Zoology of the Voyage of H.M.S. Beagle'', edited by Charles Darwin. The species was assigned to the genus '' Mus'', a once broader classification, and later placed with the genus ''Rattus''. The collection of the type specimen was made when HMS ''Beagle'' was anchored at King George Sound, a port at the southwest of the continent. The capture was noted by Darwin as "caught in a trap baited with cheese, amongst the bushes …". The type locality has been determined as Little Grove, Western Australia, south of Mount Melville in the city of Albany. The population is regarded as the ''fuscipes'' species group, as the spe ...

New Zealand Fur Seal
''Arctocephalus forsteri'' (common names include the Australasian fur seal, South Australian fur seal, New Zealand fur seal, Antipodean fur seal, or long-nosed fur seal) is a species of fur seal found mainly around southern Australia and New Zealand. The name ''New Zealand fur seal'' is used by English speakers in New Zealand; ''kekeno'' is used in the Māori language. , the common name long-nosed fur seal has been proposed for the population of seals inhabiting Australia. Although the Australian and New Zealand populations show some genetic differences, their morphologies are very similar, and thus they remain classed as a single species. After the arrival of humans in New Zealand, and particularly after the arrival of Europeans in Australia and New Zealand, hunting reduced the population to near-extinction. Description Males have been reported as large as 160 kg; their average weight is about 126 kg.Harcourt, R.G., (2001)"Advances in New Zealand mammalogy 1990–20 ...

Australian Fur Seal
The brown fur seal (''Arctocephalus pusillus''), also known as the Cape fur seal, South African fur seal and Australian fur seal, is a species of fur seal. Description The brown fur seal is the largest and most robust member of the fur seals. It has a large and broad head with a pointed snout that may be flat or turned up slightly. They have external ear flaps (pinnae) and their whiskers (vibrissae) are long, and may extend backward past the pinnae, especially in adult males. The fore flippers are covered with sparse hair over about three-quarters of their length. The hind flippers are short relative to the large body, with short, fleshy tips on the digits. The size and weight of the brown fur seal depends on the subspecies. The Southern African subspecies is on average slightly larger than the Australian subspecies. Males of the African subspecies (''A. p. pusillus'') are in length on average and weigh . Females are smaller, averaging in length and typically weighing .King, ...

Archeologist
Archaeology or archeology is the scientific study of human activity through the recovery and analysis of material culture. The archaeological record consists of Artifact (archaeology), artifacts, architecture, biofact (archaeology), biofacts or ecofacts, archaeological site, sites, and cultural landscapes. Archaeology can be considered both a social science and a branch of the humanities. It is usually considered an independent academic discipline, but may also be classified as part of anthropology (in North America – the four-field approach), history or geography. Archaeologists study human prehistory and history, from the development of the first stone tools at Lomekwi in East Africa 3.3 million years ago up until recent decades. Archaeology is distinct from palaeontology, which is the study of fossil remains. Archaeology is particularly important for learning about prehistoric societies, for which, by definition, there are no written records. Prehistory includes ove ...

Indigenous Australian
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 peoples of the Australian mainland and Tasmania, and the Torres Strait Islander peoples from the seas between Queensland and Papua New Guinea. The term Aboriginal and Torres Strait Islander peoples or the person's specific cultural group, is often preferred, though the terms First Nations of Australia, First Peoples of Australia and First Australians are also increasingly common; 812,728 people self-identified as being of Aboriginal and/or Torres Strait Islander origin in the 2021 Australian Census, representing 3.2% of the total population of Australia. Of these indigenous Australians, 91.4% identified as Aboriginal; 4.2% identified as Torres Strait Islander; while 4.4% identified with both groups.

Granite Dome
Granite domes are domical hills composed of granite with bare rock exposed over most of the surface. Generally, domical features such as these are known as bornhardts. Bornhardts can form in any type of plutonic rock but are typically composed of granite and granitic gneiss. As granitic plutons cool kilometers below the Earth's surface, minerals in the rock crystallize under uniform confining pressure. Erosion brings the rock closer to Earth's surface and the pressure from above the rock decreases; as a result the rock fractures. These fractures are known as exfoliation joints, or sheet fractures, and form in onionlike patterns that are parallel to the land surface. These sheets of rock peel off the exposed surface and in certain conditions develop domical structures. Additional theories on the origin of granite domes involve scarp-retreat and tectonic uplift. Sheet fractures Sheet fractures are arcuate fractures defining slabs of rock that range from 0.5 to 10 meters thic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Limestone
Limestone ( calcium carbonate ) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of . Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life. About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. The remaining carbonate rock is mostly dolomite, a closely related rock, which contains a high percentage of the mineral dolomite, . ''Magnesian limestone'' is an obsolete and poorly-defined term used variously for dolomite, for limes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
