Platycepsion
''Platycepsion wilksoni'' is an extinct species of prehistoric amphibian, known from partial skeleton deposited in shale at the Gosford Quarry site of the Terrigal Formation in Australia. Taxonomy The species is assigned to a currently monotypic genus, the synonym ''Platyceps wilkinsonii'', a name published in 1887 by the Australian palaeontologist William Stephens, was nominated as the type. A revision in 1964 by Oskar Kuhn assigned the species to the genus ''Platycepsion'' to replace the earlier combination, which was invalidated by an earlier use of the name ''Platyceps'' for a colubrid genus of snakes. Another revising author John W. Cosgriff named the species as the type for a new genus, ''Blinasaurus'', unaware of Kuhn's replacement of the name, and placed a second species in the same genus, later separated to a new combination as ''Batrachosuchus henwoodi''. The author noted the epithet ''Wilkinsonii'' in the first description as commemorating the deputy chair of the L ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Platyceps
''Platyceps'' is a genus of snakes of the family Colubridae endemic to Eurasia. Taxonomy The genus was erected in 1860 by Edward Blyth, allying species previously described. The genus name ''Platyceps'' was inadvertently used for a fossil species in 1877, now recognised as ''Platycepsion wilkinsoni''. Species The following 30 species are recognized as being valid. *''Platyceps afarensis'' Schätti & Ineich, 2004 *''Platyceps atayevi'' ( Tuniyev & Shammakov, 1993) *''Platyceps bholanathi'' (Sharma, 1976) *''Platyceps brevis'' (Boulenger, 1895) *''Platyceps collaris'' ( F.

Batrachosuchus Henwoodi
''Batrachosuchus henwoodi'' is a fossil species of amphibian, first described as ''Blinasaurus henwoodi'' by John W. Cosgriff in 1969. The species was placed in a new generic combination when separating the genus '' Blinasaurus'', currently subsumed as a synonym to the genus ''Platycepsion ''Platycepsion wilksoni'' is an extinct species of prehistoric amphibian, known from partial skeleton deposited in shale at the Gosford Quarry site of the Terrigal Formation in Australia.

Amphibian
Amphibians are tetrapod, four-limbed and ectothermic vertebrates of the Class (biology), class Amphibia. All living amphibians belong to the group Lissamphibia. They inhabit a wide variety of habitats, with most species living within terrestrial animal, terrestrial, fossorial, arboreal or freshwater aquatic ecosystems. Thus amphibians typically start out as larvae living in water, but some species have developed behavioural adaptations to bypass this. The young generally undergo metamorphosis from larva with gills to an adult air-breathing form with lungs. Amphibians use their skin as a secondary respiratory surface and some small terrestrial salamanders and frogs lack lungs and rely entirely on their skin. They are superficially similar to reptiles like lizards but, along with mammals and birds, reptiles are amniotes and do not require water bodies in which to breed. With their complex reproductive needs and permeable skins, amphibians are often ecological indicators; in re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Terrigal Formation
The Terrigal Formation is a geologic formation in the Sydney Basin in eastern Australia. Commonly seen in the Central Coast region, this stratum is up to 330 metres thick. Formed in the early to mid Triassic, it is part of the Narrabeen Group of sedimentary rocks. This formation includes interbedded fine to medium-grained sandstone and siltstone, with minor deposits of claystone. Hawkesbury Sandstone occasionally overlies the Terrigal Formation. See also * Sydney Basin * Munmorah Conglomerate * Newport Formation * Narrabeen group The Narrabeen group of sedimentary rocks occurs in the Sydney Basin in eastern Australia. This series of rocks was formed in the Triassic Period. Geology It includes various rock types including lithic sandstone, quartz sandstone, siltstones, ...

William Stephens (academic)
William John Stephens , FGS, (16 July 1829 – 22 November 1890) was headmaster at Sydney Grammar School, a professor at the University of Sydney and museum administrator. Stephens was born in Levens, Westmorland, the son of the Rev. William Stephens, of Heversham, Westmorland, and his wife Alicia, ''née'' Daniell. William, junior, was an elder brother of Thomas Stephens. William was educated at Marlborough College, and at The Queen's College, Oxford, where he was scholar from 1848 to 1853; Fellow from 1853 to 1860; Lecturer in 1854; and Tutor from 1855 to 1856. Professor Stephens, who graduated B.A. in 1852 and M.A. in 1855, accepted the post of headmaster of Sydney Grammar School, and held it for ten years, when he founded The New School (Eaglesfield from 1879), which he conducted with success for fifteen years. He was then appointed Professor of Geology and Palaeontology at the Sydney University, a post which he retained until his death. During the interval which elapsed be ...

Oskar Kuhn
Oskar Kuhn (7 March 1908, Munich – 1990) was a German palaeontologist. Life and career Kuhn was educated in Dinkelsbühl and Bamberg and then studied natural science, specialising in geology and paleontology, at the University of Munich, from which he received his D. Phil. in 1932. He worked in the University of Munich Geological Institute, among other things on the ''Fossilium Catalogus'' (Catalogue of Fossils), and then in 1938 on a stipend from the Deutsche Forschungsgemeinschaft, moved to the University of Halle, where he worked on the Geiseltal fossils. In 1939 he achieved his Habilitation with a thesis on the Halberstadt Keuper fauna, and in 1940 was named Privatdozent in geology and paleontology. Informed by his Catholic religion, Kuhn was an exponent of idealistic morphology: he viewed evolution as operating only within predetermined morphological classes. In 1943 he declared, "The theory of descent has collapsed." After a political conflict with his mentor, Johan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Colubrid
Colubridae (, commonly known as colubrids , from la, coluber, 'snake') is a family of snakes. With 249 genera, it is the largest snake family. The earliest species of the family date back to the Oligocene epoch. Colubrid snakes are found on every continent except Antarctica. Description While most colubrids are not venomous (or have venom that is not known to be harmful to humans) and are mostly harmless, a few groups, such as genus ''Boiga'', can produce medically significant injuries. In addition, the boomslang, the twig snakes, and the Asian genus ''Rhabdophis'' have caused human fatalities. Some colubrids are described as opisthoglyphous (often called "rear-fanged"), meaning they have elongated, grooved teeth located in the back of their upper jaws. It is likely that opisthoglyphous dentition evolved many times in the history of snakes and is an evolutionary precursor to the fangs of vipers and elapids, which are located in the front of the mouth.

Linnean Society Of New South Wales
The Linnean Society of New South Wales promotes ''the Cultivation and Study of the Science of Natural History in all its Branches'' and was founded in Sydney, New South Wales (Australia) in 1874 and incorporated in 1884. History The Society succeeded the ''Entomological Society of New South Wales'', founded in 1862 which folded in 1872, with James Charles Cox as its first president. The first issue of ''Proceedings'' was in 1875. The establishment of the Society was largely due to the dedication and financial support of its first President, Sir William Macleay. Joseph James Fletcher was director and librarian (this title was afterwards changed to secretary) from 1885 and edited 33 volumes of the ''Proceedings'' of the society. In September 1882, a fire destroyed the library and a part of the scientific material of the society. The efforts of William Macleay made it possible nevertheless for the society to continue its activities. Macleay bursary In 1903, the Society created ...
