Paracyclotosaurus
''Paracyclotosaurus'' (meaning "Near Wheeled Lizard") is an extinct genus of temnospondyl amphibian, which would have appeared similar to today's salamander – but much larger, measuring up to long and weighing between . It lived in the Middle Triassic period, about 235 million years ago, and fossils have been found in Australia, India, and South Africa. Although they could live on dry land, ''Paracyclotosaurus'' probably spent most of its time in water. They had flattened bodies and elongated heads, almost long, that vaguely resembled those of modern crocodiles. Discovery and naming The type species ''P. davidi'' is only known from one complete specimen recovered from Australia. It was discovered by quarry miners in a brick pit in St. Peters in Sydney, New South Wales. The discovery, made in 1910, was from a large ironstone nodule within Ashfield Shale which contained the nearly complete skeleton. The reconstruction was finished in July 1914, and was initially determined t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ashfield Shale
Ashfield Shale is part of the Wianamatta group of sedimentary rocks in the Sydney Basin. It lies directly on contemporaneously eroded Hawkesbury sandstone or the Mittagong formation. These rock types were formed in the Triassic Period. It is named after the Sydney suburb of Ashfield. Some of the early research was performed at the old Ashfield Brickworks Quarry. This rock type is often associated with the Inner West and North Shore of the city. However, it has also been recorded at Penrith, Revesby, Bilpin and Mount Irvine. Description Ashfield Shale comprises black mudstones and grey shales with frequent sideritic clay ironstone bands. The thickness ranges between 45 and 64 metres. It is 20 metres thick at the Sydney Olympic Site. The chemistry of the rock is typical of shales, with high iron levels, and some iron sulphide and low calcium levels. The geology of the shale lenses within the Hawkesbury Sandstone is chemically similar to the Ashfield Shale. At Turra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
St Peters, New South Wales
St Peters is a suburb in the Inner West of Sydney, in the state of New South Wales, Australia. It is 7 kilometres south of the Sydney central business district, in the local government area of Inner West Council, with a small section in the southeast in the City of Sydney. History St Peters was named by its association with St Peters Anglican Church, which was consecrated in 1838. St Peters is the third oldest Anglican church in Sydney and has been claimed to be the first church built in Australia using non-convict labour. The church is on the Princes Highway. It was designed by Thomas Bird and built in 1838–39. In 1875, alterations were carried out under the supervision of Edmund Blacket. The church is now listed on the Register of the National Estate. The graveyard is the burial place of a few notable people, including solicitor and merchant Frederick Wright Unwin, who had Unwin Road and Unwin's Bridge named after him. It is also the burial place of people who committed sui ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Temnospondyli
Temnospondyli (from Greek τέμνειν, ''temnein'' 'to cut' and σπόνδυλος, ''spondylos'' 'vertebra') is a diverse order of small to giant tetrapods—often considered primitive amphibians—that flourished worldwide during the Carboniferous, Permian, and Triassic periods. A few species continued into the Jurassic and Cretaceous periods. Fossils have been found on every continent. During about 210 million years of evolutionary history, they adapted to a wide range of habitats, including freshwater, terrestrial, and even coastal marine environments. Their life history is well understood, with fossils known from the larval stage, metamorphosis, and maturity. Most temnospondyls were semiaquatic, although some were almost fully terrestrial, returning to the water only to breed. These temnospondyls were some of the first vertebrates fully adapted to life on land. Although temnospondyls are considered amphibians, many had characteristics, such as scales and armour-like bon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyclotosaurus
''Cyclotosaurus'' is an extinct genus of temnospondyl within the family Mastodonsauridae. It was of great size for an amphibian, had an elongated skull up to . Etymology The name means "round eared lizard" in Ancient Greek, derived from round openings or fenestrae in the cheeks, which are thought to contain structures of the middle ear. History German naturalist Eberhard Fraas erected the genus ''Cyclotosaurus'' in 1889, with ''C. robustus'' (previously ''Mastodonsaurus robustus'') as the type species. Several species are known, mainly from Germany and Poland in Central Europe, as well as East Greenland and Thailand. The relationships between species is unclear. ''"Labyrinthodon" pachygnathus'' Owen, 1842 and ''"L." leptognathus'' Owen, 1842 were transferred to ''Cyclotosaurus'', as ''C. pachygnathus'' and ''C. leptognathus'', by Paton (1974). However, Damiani (2001) assigned the two species to Mastodonsauroidea indeterminate and Stereospondyli indeterminate. Palaeontology ...

Triassic
The Triassic ( ) is a geologic period and system which spans 50.6 million years from the end of the Permian Period 251.902 million years ago ( Mya), to the beginning of the Jurassic Period 201.36 Mya. The Triassic is the first and shortest period of the Mesozoic Era. Both the start and end of the period are marked by major extinction events. The Triassic Period is subdivided into three epochs: Early Triassic, Middle Triassic and Late Triassic. The Triassic began in the wake of the Permian–Triassic extinction event, which left the Earth's biosphere impoverished; it was well into the middle of the Triassic before life recovered its former diversity. Three categories of organisms can be distinguished in the Triassic record: survivors from the extinction event, new groups that flourished briefly, and other new groups that went on to dominate the Mesozoic Era. Reptiles, especially archosaurs, were the chief terrestrial vertebrates during this time. A specialized subgroup of archo ...

Prehistoric Tetrapod Genera
Prehistory, also known as pre-literary history, is the period of human history between the use of the first stone tools by hominins 3.3 million years ago and the beginning of recorded history with the invention of writing systems. The use of symbols, marks, and images appears very early among humans, but the earliest known writing systems appeared 5000 years ago. It took thousands of years for writing systems to be widely adopted, with writing spreading to almost all cultures by the 19th century. The end of prehistory therefore came at very different times in different places, and the term is less often used in discussing societies where prehistory ended relatively recently. In the early Bronze Age, Sumer in Mesopotamia, the Indus Valley Civilisation, and ancient Egypt were the first civilizations to develop their own scripts and to keep historical records, with their neighbors following. Most other civilizations reached the end of prehistory during the following Iron Age. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
