Acrolepidae
Acrolepididae is an extinct family of ray-finned fish. Genera referred to Acrolepididae existed from the Early Carboniferous period to the Early Triassic epoch. They were nektonic carnivores with a fusiform body. Acrolepididae may be closely related with the Early Mesozoic Ptycholepididae.

Acrolepis
''Acrolepis'' (Ancient Greek for "tip scale") is an extinct genus of prehistoric bony fish that lived from the Tournaisian stage of the Mississippian (early Carboniferous) to the late Permian epoch. Some species from the Early Triassic of Tasmania are also ascribed to ''Acrolepis''. It is a large piscivorous predatory fish in the acrolepid family, which occupy an apex predator niche in its locale. ''A. gigas'' was estimated to have grown up to in length. A close relationship between the mostly Palaeozoic Acrolepidae and the Mesozoic Ptycholepiformes was proposed, but support from phylogenetic analyses is scarce. Diet ''Acrolepis'' possibly used its sharp, pointed teeth to catch small fish (most primarily Palaeonisciformes). Fossil record The type species is ''Acrolepis sedgwicki'' from the late Permian Marl Slate of England and the coeval Kupferschiefer of Germany. Other species are known from Carboniferous and Permian rocks in the Czech Republic and Triassic layer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ptycholepiformes
Ptycholepiformes are an extinct order of prehistoric ray-finned fish that existed during the Triassic period and the Early Jurassic epoch. The order includes the genera '' Acrorhabdus'', ''Ardoreosomus'', ''Boreosomus'', '' Chungkingichthys'', '' Ptycholepis'', and '' Yuchoulepis''. Although several families have been proposed, some studies place all these genera in the same family, Ptycholepididae. Ptycholepiformes had a widespread distribution during the Early Triassic, but were restricted to mainly Europe and North America afterwards. They are known from both marine and freshwater deposits. Appearance Typical features of ptycholepiforms are the fusiform body covered in rhombic ganoid scales, the anterior position of the dorsal fin. In most coeval ray-fins the dorsal fin has a more posterior position), usually situated opposite to the anal fin. Moreover, ptycholepiforms show a series of elongate, horizontal suborbital bones. The skull is usually relatively large. The scal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tournaisian
The Tournaisian is in the ICS geologic timescale the lowest stage or oldest age of the Mississippian, the oldest subsystem of the Carboniferous. The Tournaisian age lasted from Ma to Ma. It is preceded by the Famennian (the uppermost stage of the Devonian) and is followed by the Viséan. Name and regional alternatives The Tournaisian was named after the Belgian city of Tournai. It was introduced in scientific literature by Belgian geologist André Hubert Dumont in 1832. Like many Devonian and lower Carboniferous stages, the Tournaisian is a unit from West European regional stratigraphy that is now used in the official international time scale. The Tournaisian correlates with the regional North American Kinderhookian and lower Osagean stages and the Chinese Tangbagouan regional stage. In British stratigraphy, the Tournaisian contains three substages: the Hastarian, Ivorian and lower part of the Chadian (the upper part falls in the Viséan). Stratigraphy The base of the ...

Arthur Smith Woodward
Sir Arthur Smith Woodward, FRS (23 May 1864 – 2 September 1944) was an English palaeontologist, known as a world expert in fossil fish. He also described the Piltdown Man fossils, which were later determined to be fraudulent. He is not related to Henry Woodward, whom he replaced as curator of the Geology Department of the British Museum of Natural History. Biography Woodward was born in Macclesfield, Cheshire, England and was educated there and at Owens College, Manchester. He joined the staff of the Department of Geology at the Natural History Museum in 1882. He became assistant Keeper of Geology in 1892, and Keeper in 1901. He was appointed Secretary of the Palaeontographical Society and in 1904, was appointed President of the Geological Society. He was elected in June 1901 a Fellow of the Royal Society He was the world expert on fossil fish, writing his ''Catalogue of the Fossil Fishes in the British Museum'' (1889–1901). His travels included journeys to South America ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Georg Gürich
Georg Julius Ernst Gürich (25 September 1859, in Dobrodzień, German: Guttentag; Upper Silesia – 16 August 1938 in Berlin) was a German geologist, paleontologist and university teacher, who wrote on Paleozoic geological formations in PolandGürich, "Das Paläozoikum des Polnischen Mittelgebirge", ''Verhandlungen der Russischen Kaiserlichen Gesellschaft zu Saint Petersburg'' 32 1898:1–539). and ranged through Guinea, Tanzania and Southern Africa (at the time German colonies), in search of unrecorded new species. Georg Gürich studied geology in Breslau/Wroclaw (1884–1891, Ph.D. 1882). In 1885, he first went to Africa, participating in a German scientific expedition to Nigeria and travelled in the western Sudan (1885), and in South-West Africa, now Namibia (May 1888 to January 1889), mostly in the western mountains from Otjitambi to Rehoboth, to do geological research on behalf of the "Southwest African Gold Syndicate" (''Südwestafrikanisches Goldsyndikat''), with the aim ...

Type Species
In zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological type specimen(s). Article 67.1 A similar concept is used for suprageneric groups and called a type genus. In botanical nomenclature, these terms have no formal standing under the code of nomenclature, but are sometimes borrowed from zoological nomenclature. In botany, the type of a genus name is a specimen (or, rarely, an illustration) which is also the type of a species name. The species name that has that type can also be referred to as the type of the genus name. Names of genus and family ranks, the various subdivisions of those ranks, and some higher-rank names based on genus names, have such types.

Ramsay Traquair
Ramsay Heatley Traquair Fellow of the Royal Society of Edinburgh, FRSE Fellow of the Royal Society of London, FRS (30 July 1840 – 22 November 1912) was a Scottish naturalist and palaeontologist who became a leading expert on fossil fish. Traquair trained as a medical doctor, but his thesis was on aspects of fish anatomy. He held posts as Professor of Natural History and Professor of Zoology in England and Ireland, before returning to his native Edinburgh to take up a post at the Royal Scottish Museum, Museum of Science and Art. He spent the rest of his career there, building up a renowned collection of fossil fish over a period of more than three decades. He published extensively on palaeoichthyology, authoring many papers and a series of monographs. His studies of rocks and fossils in Scotland overturned earlier work on fossil fish, establishing new taxonomic classifications. His honours included fellowships from a range of learned societies, including the Royal Society of E ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
