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: ' ...

Agrosaurus
''Agrosaurus'' (; perhaps from Greek ''agros'' meaning 'field' and ''sauros'' meaning 'lizard', "field lizard") is an extinct genus of thecodontosaurid sauropodomorph probably originating from England that was originally believed to be a Triassic prosauropod from Australia. ''Agrosaurus'' would thus be the oldest dinosaur from that country. However, this appears to have been an error, and the material actually appears to come from ''Thecodontosaurus'' or a ''Thecodontosaurus''-like animal from Bristol, England (Avon Fissure Fill). The type species is ''Agrosaurus macgillivrayi''. History Members of an expedition from the British sloop-of-war HMS ''Fly'' supposedly collected two tibiae, a fibula and two foot claws as well as some other fragments in 1844 while erecting a beacon on the coast of Cape York, Queensland in Australia. The context of the discovery is uncertain, as it is not mentioned in books by expedition naturalist John MacGallivray, nor in a 1847 book on the voya ...

Pantydraco
''Pantydraco'' (where "panty-" is short for Pant-y-ffynnon, signifying ''hollow of the spring/well'' in Welsh, referring to the quarry at Bonvilston in South Wales where it was found) was a genus of basal sauropodomorph dinosaur from the Late Triassic of the United Kingdom (Wales). It is based on a partial juvenile skeleton once thought to belong to ''Thecodontosaurus''. Only one valid species of ''Pantydraco'' is recognised: ''P. caducus.'' Description ''Pantydraco'' was of moderate build. The creature had a long tail that tapered towards the end and was broad at the hip joint. It had a pointed head with a strong jaw. The forelimbs of the dinosaur were developed for grasping while the hindlimbs were adapted for supporting the creature's body weight. The center of mass lies near the pelvic bone, meaning the creature was bipedal. The forelimbs were shorter than the hindlimbs. The hands had three movable digits while the fourth digit was embedded. It had well-developed claws. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Henry Riley (scientist)
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] |
Magnesian Conglomerate
The Magnesian Conglomerate is a geological formation in Clifton, Bristol in England (originally Avon), Gloucestershire and southern Wales, present in Tytherington, Durdham Down and Cromhall Quarry. It dates back to the Rhaetian stage of the Late Triassic,Magnesian Conglomerate in the Weishampel et al., 2004, pp. 521–525 although it may be as old as the stage of the Late Triassic and as young as the |

Sauropodomorph
Sauropodomorpha ( ; from Greek, meaning "lizard-footed forms") is an extinct clade of long-necked, herbivorous, saurischian dinosaurs that includes the sauropods and their ancestral relatives. Sauropods generally grew to very large sizes, had long necks and tails, were quadrupedal, and became the largest animals to ever walk the Earth. The '' prosauropods,'' which preceded the sauropods, were smaller and were often able to walk on two legs. The sauropodomorphs were the dominant terrestrial herbivores throughout much of the Mesozoic Era, from their origins in the Late Triassic (approximately 230 Ma) until their decline and extinction at the end of the Cretaceous. Description Sauropodomorphs were adapted to browsing higher than any other contemporary herbivore, giving them access to high tree foliage. This feeding strategy is supported by many of their defining characteristics, such as: a light, tiny skull on the end of a long neck (with ten or more elongated cervical vertebrae) ...

John Morris (geologist)
John Morris (19 February 1810 – 7 January 1886) was an English geologist. Life He was born in 1810 at Homerton, London, and educated at private schools. He was engaged for some years as a pharmaceutical chemist at Kensington, but soon became interested in geology and other branches of science, and ultimately retired from business. His published papers speedily attracted notice, and his ''Catalogue of British Fossils,'' published in 1845, a work involving much critical research, added greatly to his reputation. Morris was professor of geology at University College, London from 1854 to 1877. He was elected F.G.S. in 1845. Along with Bowerbank and five others, he was a founding member of the London Clay Club. Morris was president of the Geologists' Association from 1868 to 1871 and from 1877 to 1879. He was awarded the Lyell Medal in 1876. Morris's best original work was done on Eocene and Jurassic rocks. His ''Catalogue of British Fossils'' was an important pioneering eff ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clifton, Bristol
Clifton is both a suburb of Bristol, England, and the name of one of the city's thirty-five council wards. The Clifton ward also includes the areas of Cliftonwood and Hotwells.
