Poekilopleuron Bucklandii
''Poekilopleuron'' (meaning "varied ribs") is a genus of tetanuran dinosaur, which lived during the middle Bathonian of the Jurassic, about 168 to 166 million years ago. The genus has been used under many different spelling variants, although only one, ''Poekilopleuron'', is valid. The type species is ''P. bucklandii'', named after William Buckland, and many junior synonyms of it have also been erected. Few material is currently known, as the holotype was destroyed in World War II, although many casts of the material still exist. Discovery and naming ''Poekilopleuron'' is a genus of theropod with a long and complex history. The holotype was discovered in July 1835 near La Maladrerie and the genus was named and first described by Jacques Amand Eudes-Deslongchamps in a report published in 1836, based on holotype material that is now destroyed. In 1837, Eudes-Deslongchamps published a more detailed account of this discovery in a monographEudes-Deslongchamps J.-A. (1837) Mémoire ...

Samuel Stutchbury
Samuel Stutchbury (15 January 1798 – 12 February 1859) was an English naturalist and geologist. Alongside Henry Riley, Stutchbury was the co-discoverer of ''Thecodontosaurus'', which in 1836 was the fourth dinosaur genus to be named. He also played a part in Gideon Mantell's naming of ''Iguanodon''. As a geological surveyor he mapped a large area of eastern Australia. Early life Stutchbury was born on 15 January 1798 in London, the son of a gauging instrument maker. In 1820 he became assistant conservator at the Hunterian Museum at the Royal College of Surgeons and in 1821 was made an associate of the Linnean Society of London. In 1824 he had a part in Gideon Mantell's identification of ''Iguanodon'', which in 1825 would become the second dinosaur to be formally named. It was Stutchbury who realised that Mantell's fossils of teeth resembled the teeth of the iguana specimen which Stutchbury had just prepared at the Hunterian Museum. In 1825 he sailed on and later as a zoolog ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thecodontosaurus
''Thecodontosaurus'' ("socket-tooth lizard") is a genus of herbivorous basal sauropodomorph dinosaur that lived during the late Triassic period (Rhaetian age). Its remains are known mostly from Triassic "fissure fillings" in South England. ''Thecodontosaurus'' was a small bipedal animal, about 2 m (6.5 ft) long. It is one of the first dinosaurs to be discovered and is one of the oldest that existed. Many species have been named in the genus, but only the type species ''Thecodontosaurus antiquus'' is seen as valid today. Discovery and naming ''Thecodontosaurus antiquus'' In the autumn of 1834, surgeon Henry Riley (1797–1848) and the curator of the Bristol Institution, Samuel Stutchbury, began to excavate "saurian remains" at the quarry of Durdham Down, at Clifton, presently a part of Bristol, which is part of the Magnesian Conglomerate. In 1834 and 1835, they briefly reported on the finds. They provided their initial description in 1836, naming a new genus: ' ...

Rileyasuchus
''Rileyasuchus'' is a genus of phytosaur from the Rhaetian (Late Triassic) Magnesian Conglomerate of England. It has a confusing history, being associated with the taxonomy of ''Palaeosaurus'' and ''Thecodontosaurus'', and being a replacement name for a preoccupied genus (''Rileya'', which had already been used by Ashmead, and Howard both in 1888 for a hymenopteran).Howard, L.O.

Durdham Down
Durdham Down is an area of public open space in Bristol, England. With its neighbour Clifton Down to the southwest, it constitutes a area known as The Downs, much used for leisure including walking, jogging and team sports. Its exposed position makes it particularly suitable for kite flying. Durdham Down is the part of the Downs north of Stoke Road. History Durdham Down was long used as grazing land. An Anglo-Saxon charter of 883 grants grazing rights over part of Durdham Down. The down was the commons of pasture for the manor of Henbury during the Middle Ages. The land was also valuable farmland used by many farms in the area. In 1643 and 1645, during the English Civil War, Royalist and Parliamentarian armies assembled on the down. In 1857, concerned by Victorian-built houses encroaching on the open space as the city expanded, the Bristol Corporation acquired commoners' rights on the downs, and exercised them the following year by grazing sheep. In 1861 Durdham Down i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rhaetian
The Rhaetian is the latest age of the Triassic Period (in geochronology) or the uppermost stage of the Triassic System (in chronostratigraphy). It was preceded by the Norian and succeeded by the Hettangian (the lowermost stage or earliest age of the Jurassic). The base of the Rhaetian lacks a formal GSSP, though candidate sections include Steinbergkogel in Austria (since 2007) and Pignola-Abriola in Italy (since 2016). The end of the Rhaetian (and the base of the overlying Hettangian Stage) is more well-defined. According to the current ICS (International Commission on Stratigraphy) system, the Rhaetian ended ± 0.2 Ma ( million years ago). In 2010, the base of the Rhaetian (i.e. the Norian-Rhaetian boundary) was voted to be defined based on the first appearance of '' Misikella posthernsteini'', a marine conodont. However, there is still much debate over the age of this boundary, as well as the evolution of ''M. posthernsteini''. The most comprehensive source of precise ...

Late Triassic
The Late Triassic is the third and final epoch (geology), epoch of the Triassic geologic time scale, Period in the geologic time scale, spanning the time between annum, Ma and Ma (million years ago). It is preceded by the Middle Triassic Epoch and followed by the Early Jurassic Epoch. The corresponding series (stratigraphy), series of rock beds is known as the Upper Triassic. The Late Triassic is divided into the Carnian, Norian and Rhaetian Geologic time scale, Ages. Many of the first dinosaurs evolved during the Late Triassic, including ''Plateosaurus'', ''Coelophysis'', and ''Eoraptor''. The Triassic–Jurassic extinction event began during this epoch and is one of the five major mass extinction events of the Earth. Etymology The Triassic was named in 1834 by Friedrich August von Namoh, Friedrich von Alberti, after a succession of three distinct rock layers (Greek meaning 'triad') that are widespread in southern Germany: the lower Buntsandstein (colourful sandstone'')'', t ...

Henry Riley (paleontologist)
Henry Riley (1797–1848) was a British surgeon, anatomist, naturalist, geologist and paleontologist. He is notable for being the co-discoverer and co-describer of the archosaur ''Palaeosaurus'' and the dinosaur ''Thecodontosaurus''. Biography Henry Riley was born in Bristol in 1797.The Geological Curator, 10 (8). pp. 493-498. He trained to become a surgeon in Paris and he graduated during the mid-1820s. He was one of the men who founded the Bristol Institution in the 1820s. Riley was involved in a body snatching scandal in the late 1820s - he was fined £6 ( inflated to £657.29 in 2019) in 1828. He was later revoked of this claim during the 1830s. His Geoffroyan lectures of 1831-33 were the first to be heard in Bristol. He was a physician at St. Peter's Hospital, Bristol in 1832 and the Bristol Royal Infirmary between 1834-1847. He taught at Bristol Medical School until he retired in 1846. In the autumn of 1834, Riley and the curator of the Bristol Institution, Samuel Stu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jacques Amand Eudes-Deslongchamps
Jacques Amand Eudes-Deslongchamps (17 January 179417 January 1867) was a French naturalist and paleontologist. His son, Eugène Eudes-Deslongchamps (1830–1889), was also a paleontologist. He was born at Caen in Normandy. His parents, though poor, contrived to give him a good education, and he studied medicine in his native town to such good effect that in 1812 he was appointed assistant-surgeon in the navy, and in 1815 surgeon assistant major to the military hospital of Caen. Soon afterwards he proceeded to Paris to qualify for the degree of doctor of surgery, and there the researches and teachings of Cuvier attracted his attention to subjects of natural history and palaeontology. In 1822 he was elected surgeon to the board of relief at Caen, and while he never ceased to devote his energies to the duties of this post, he sought relaxation in geological studies. Soon he discovered remains of '' Teleosaurus'' in one of the Caen quarries, and he became an ardent palaeontologist. H ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nomen Dubium
In binomial nomenclature, a ''nomen dubium'' (Latin for "doubtful name", plural ''nomina dubia'') is a scientific name that is of unknown or doubtful application. Zoology In case of a ''nomen dubium'' it may be impossible to determine whether a specimen belongs to that group or not. This may happen if the original type series (i. e. holotype, isotype, syntype or paratype) is lost or destroyed. The zoological and botanical codes allow for a new type specimen, or neotype, to be chosen in this case. A name may also be considered a ''nomen dubium'' if its name-bearing type is fragmentary or lacking important diagnostic features (this is often the case for species known only as fossils). To preserve stability of names, the ''International Code of Zoological Nomenclature'' allows a new type specimen, or neotype, to be chosen for a ''nomen dubium'' in this case. 75.5. Replacement of unidentifiable name-bearing type by a neotype. When an author considers that the taxonomic identity ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Palaeosaurus
''Palaeosaurus'' (or ''Paleosaurus'') is a genus of indeterminate archosaur known from two teeth found in the Bromsgrove Sandstone Formation and also either the Magnesian Conglomerate or the Avon Fissure Fill of Clifton, Bristol, England (originally Avon). It has had a convoluted taxonomic history. Richard Owen's mistake of associating prosauropod skeletal remains with the carnivorous teeth which Riley and Stutchbury called ''Palaeosaurus'', combined with Friedrich von Huene's '' Teratosaurus minor'', which was also a combination of carnivore and prosauropod remains, led paleontologists to view prosauropods as carnivorous animals for quite a long time. This error made it into several textbooks and other dinosaur reference works. History and classification Nineteenth century In the autumn of 1834, surgeon Henry Riley (1797–1848) and the curator of the Bristol Institution, Samuel Stutchbury (15 January 1798 – 12 February 1859), began to excavate "saurian remains" at ...
