Acrolepididae
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.

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] |
Challaia
''Challaia'' is an extinct genus of prehistoric freshwater ray-finned fish that lived during the Triassic period in what is now Argentina ( Mendoza). Two species are known, ''C. magna'' ( type species), most likely from the Cerro de Las Cabras Formation, and ''C. elongata'' (previously assigned to '' Myriolepis'') from the Los Rastros Formation. Three other species, ''C. multidentata'', ''C. striata'' and ''C.''? ''cacheutensis'', are considered ''nomina dubia''. ''C. elongata'' is the youngest known member of the Acrolepididae, a family of early ray-finned fishes that was dominant throughout the late Paleozoic, and survived into the Triassic.

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 ...

Mesozoic
The Mesozoic Era ( ), also called the Age of Reptiles, the Age of Conifers, and colloquially as the Age of the Dinosaurs is the second-to-last era of Earth's geological history, lasting from about , comprising the Triassic, Jurassic and Cretaceous Period (geology), Periods. It is characterized by the dominance of archosaurian reptiles, like the dinosaurs; an abundance of conifers and ferns; a hot Greenhouse and icehouse earth, greenhouse climate; and the tectonic break-up of Pangaea. The Mesozoic is the middle of the three eras since Cambrian explosion, complex life evolved: the Paleozoic, the Mesozoic, and the Cenozoic. The era began in the wake of the Permian–Triassic extinction event, the largest well-documented mass extinction in Earth's history, and ended with the Cretaceous–Paleogene extinction event, another mass extinction whose victims included the non-avian dinosaurs, Pterosaur, pterosaurs, Mosasaur, mosasaurs, and Plesiosaur, plesiosaurs. The Mesozoic was a time of ... [...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 ...

Ángel Cabrera (naturalist)
Ángel Cabrera (19 February 1879 – 8 July 1960) was a Spanish zoologist. He was born in Madrid and studied at the Universidad Central, Madrid (now part of the Universidad Complutense de Madrid). He worked the National Museum of Natural Sciences from 1902, going on several collecting expeditions to Morocco. In 1907, he proposed that the Iberian wolf was a separate subspecies, which he named ''Canis lupus signatus''. In 1925 Cabrera went to Argentina and remained there for the rest of his life. He was head of the Department of Vertebrate Paleontology at the Museo de La Plata, and made collecting trips to Patagonia and Catamarca. In Patagonia he discovered the first Jurassic dinosaur of South America; he thus began a series of discoveries in this region, one of the richest in dinosaur remains. He supervised the doctoral work of some of the first palaeontologists of South America, including Mathilde Dolgopol de Sáez and Dolores López Aranguren. His son Ángel Lulio Cab ...

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.

His honours included fellowships from a range of learned societies, including the Royal Society of E ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pteronisculus
''Pteronisculus'' is an extinct genus of prehistoric ray-finned fish that lived during the Early Triassic and Middle Triassic epochs of the Triassic period. It was first described under the name "''Glaucolepis''" by Erik Stensiö in 1921 and was later shown to be a synonym of ''Pteronisculus'' described by Errol White in 1933. However, because the name "''Glaucolepis''" is preoccupied (it had already been given to the extant lepidopteran '' Glaucolepis'' Braun, 1917), ''Pteronisculus'' became the valid genus name for the Triassic fish.White, E. I. and Moy-Thomas, J. A. (1940): VII.—Notes on the nomenclature of fossil fishes. Part II. Homonyms D–L: Journal of Natural History 11:98–103 Appearance and distribution Like many other early ray-finned fishes, ''Pteronisculus'' had a bullet-shaped skull with large eyes near the front end, and a large gape armed with small to large, conical teeth. Its body was covered with small rhombic scales that show peg-and-socket articulatio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lawrence Lambe
Lawrence Morris Lambe (August 27, 1863 – March 12, 1919) was a Canadian geologist, palaeontologist, and ecologist from the Geological Survey of Canada (GSC). His published work, describing the diverse and plentiful dinosaur discoveries from the fossil beds in Alberta, did much to bring dinosaurs into the public eye and helped usher in the ''Golden Age of Dinosaurs'' in the province. During this period, between the 1880s and World War I, dinosaur hunters from all over the world converged on Alberta. ''Lambeosaurus'', a well-known hadrosaur, was named after him as a tribute, in 1923. In addition to paleontology, Lambe discovered a number of invertebrate species ranging from Canada to the Pacific Northwest. Lambe's contemporary discoveries were published in works such as ''Sponges From the Atlantic Coast of Canada'' and ''Catalogue of the recent marine sponges of Canada and Alaska''. Early life and education Lambe was born in Montreal on August 27, 1863. Lambe studied at the Royal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
