Rottnest Island
Rottnest Island (), often colloquially referred to as "Rotto", is a Islands of Perth, Western Australia, island off the coast of Western Australia, located west of Fremantle. A sandy, low-lying island formed on a base of aeolianite limestone, Rottnest is an A-class reserve, the highest level of protection afforded to Crown land#Australia, public land. Together with Garden Island (Western Australia), Garden Island, Rottnest Island is a remnant of Pleistocene dune ridges. Along with several other islands, Rottnest became separated from the mainland when sea levels rose around 7,000 years ago. The traditional Noongar name for the island is , which means "place across the water where the spirits are". Human artefacts have been found on the island dating back at least 30,000 years, but visitation and habitation of the island by the Noongar people appears to have ceased following its separation from the mainland.

Chert
Chert () is a hard, fine-grained sedimentary rock composed of microcrystalline or cryptocrystalline quartz, the mineral form of silicon dioxide (SiO2). Chert is characteristically of biological origin, but may also occur inorganically as a precipitation (chemistry), chemical precipitate or a diagenesis, diagenetic replacement, as in petrified wood. Chert is typically composed of the petrified remains of siliceous ooze, the biogenic sediment that covers large areas of the deep ocean floor, and which contains the silicon skeletal remains of diatoms, Dictyochales, silicoflagellates, and radiolarians. Precambrian cherts are notable for the presence of fossil cyanobacteria. In addition to Micropaleontology, microfossils, chert occasionally contains macrofossils. However, some chert is devoid of any fossils. Chert varies greatly in color, from white to black, but is most often found as gray, brown, grayish brown and light green to rusty redW.L. Roberts, T.J.

Paleosol
In Earth science, geoscience, paleosol (''palaeosol'' in Great Britain and Australia) is an ancient soil that formed in the past. The definition of the term in geology and paleontology is slightly different from its use in soil science. In geology and paleontology, a paleosol is a former soil preserved by burial underneath either sediments (alluvium or loess) or volcanic deposits (lava flows or volcanic ash), which in the case of older deposits have Lithification, lithified into Rock (geology), rock. In Quaternary geology, sedimentology, paleoclimatology, and geology in general, it is the typical and accepted practice to use the term "paleosol" to designate such "''fossil soils''" found buried within sedimentary and volcanic deposits exposed in all continents. In soil science the definition differs slightly: paleosols are soils formed long ago that have no relationship in their chemical and physical characteristics to the present-day climate or vegetation. Such soils are found ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Holocene
The Holocene () is the current geologic time scale, geological epoch, beginning approximately 11,700 years ago. It follows the Last Glacial Period, which concluded with the Holocene glacial retreat. The Holocene and the preceding Pleistocene together form the Quaternary period. The Holocene is an interglacial period within the ongoing Ice age, glacial cycles of the Quaternary, and is equivalent to Marine isotope stages, Marine Isotope Stage 1. The Holocene correlates with the last maximum axial tilt towards the Sun of the Earth#Axial tilt and seasons, Earth's obliquity. The Holocene corresponds with the rapid proliferation, growth, and impacts of the human species worldwide, including Recorded history, all of its written history, technological revolutions, development of major civilizations, and overall significant transition towards urban culture, urban living in the present. The human impact on modern-era Earth and its ecosystems may be considered of global significance for th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rottnest Island Pine
''Callitris preissii'' is a species of conifer in the family Cupressaceae, endemic to Rottnest Island, Australia. Common names include Rottnest Island pine, Murray pine, maroong, southern cypress pine, and slender cypress pine. The Noongar peoples know the tree as ''marro''. Description The pine can have a tree or shrub-like habit typically growing to a height of and a width of up to . It is relatively slow growing. The crown is commonly made up fine, dense foliage. The leaf is rounded on the dorsal side and the cones often have a width of over with scales that do not separate from the base. It starts producing brown-yellow-orange cones between October and January. The root system is generally moderate to deep or shallow and spreading. It is reasonably long lived, usually to over 15 years of age. Distribution It is endemic to the Swan Coastal Plain, Rottnest Island and Garden Island but has become naturalised elsewhere and now has a scattered distribution throughout the Mid We ...

Arctocephalus Forsteri
''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.

Australian Sea Lion
The Australian sea lion (''Neophoca cinerea''), also known as the Australian sea-lion or Australian sealion, is a species of sea lion that is the only endemic pinniped in Australia. It is currently Monotypic taxon, monotypic in the genus ''Neophoca'', with the extinct Pleistocene New Zealand sea lion ''Neophoca palatina'' the only known congener. With a population estimated at 14,730 animals, the Wildlife Conservation Act of Western Australia (1950) has listed them as "in need of special protection". Their conservation status is listed as Endangered species, endangered. These pinnipeds are specifically known for their abnormal breeding cycles, which are varied between a 5-month breeding cycle and a 17-18 month aseasonal breeding cycle, compared to other pinnipeds, which fit into a 12-month reproductive cycle. Females are either silver or fawn with a cream underbelly, and males are dark brown with a yellow mane and are bigger than the females. Distribution Australian sea lions ar ...
