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 ...

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: ''Thecodo ...

Avon Fissure Fill
The Avon Fissure Fill, also known as the Bristol Fissure Fill or Tytherington Fissure Fill, is a fissure fill in Avon, England (now Bristol) which dates variously from the Norian and Rhaetian stages of the Late Triassic, or possibly as late as the Hettangian stage of the Early Jurassic.Langer, 2004. Basal Saurischia. In Weishampel, Dodson and Osmolska. ''The Dinosauria Second Edition''. ''University of California Press''. 861 pp. The fissure fill at Avon was a sinkhole formed by the dissolution of Lower Carboniferous limestones. It is paired with the nearby Magnesian Conglomerate; it may have been the same formation as the Magnesian Conglomerate.Magnesian Conglomerate in the |
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 age ...

Autumn
Autumn, also known as fall in American English and Canadian English, is one of the four temperate seasons on Earth. Outside the tropics, autumn marks the transition from summer to winter, in September ( Northern Hemisphere) or March ( Southern Hemisphere). Autumn is the season when the duration of daylight becomes noticeably shorter and the temperature cools considerably. Day length decreases and night length increases as the season progresses until the Winter Solstice in December (Northern Hemisphere) and June (Southern Hemisphere). One of its main features in temperate climates is the striking change in colour for the leaves of deciduous trees as they prepare to shed. Date definitions Some cultures regard the autumnal equinox as "mid-autumn", while others with a longer temperature lag treat the equinox as the start of autumn. In the English-speaking world of high latitude countries, autumn traditionally began with Lammas Day and ended around Hallowe'en, the approxima ...

Fibula
The fibula or calf bone is a leg bone on the lateral side of the tibia, to which it is connected above and below. It is the smaller of the two bones and, in proportion to its length, the most slender of all the long bones. Its upper extremity is small, placed toward the back of the head of the tibia, below the knee joint and excluded from the formation of this joint. Its lower extremity inclines a little forward, so as to be on a plane anterior to that of the upper end; it projects below the tibia and forms the lateral part of the ankle joint. Structure The bone has the following components: * Lateral malleolus * Interosseous membrane connecting the fibula to the tibia, forming a syndesmosis joint * The superior tibiofibular articulation is an arthrodial joint between the lateral condyle of the tibia and the head of the fibula. * The inferior tibiofibular articulation (tibiofibular syndesmosis) is formed by the rough, convex surface of the medial side of the lower end of the f ...

Cape York Peninsula
Cape York Peninsula is a large peninsula located in Far North Queensland, Australia. It is the largest unspoiled wilderness in northern Australia.Mittermeier, R.E. et al. (2002). Wilderness: Earth’s last wild places. Mexico City: Agrupación Sierra Madre, S.C. The land is mostly flat and about half of the area is used for grazing cattle. The relatively undisturbed eucalyptus-wooded savannahs, tropical rainforests and other types of habitat are now recognised and preserved for their global environmental significance. Although much of the peninsula remains pristine, with a diverse repertoire of endemic flora and fauna, some of its wildlife may be threatened by industry and overgrazing as well as introduced species and weeds.Mackey, B. G., Nix, H., & Hitchcock, P. (2001). The natural heritage significance of Cape York Peninsula. Retrieved 15 January 2008, froepa.qld.gov.au. The northernmost point of the peninsula is Cape York ().

Joseph Jukes
Joseph Beete Jukes (10 October 1811 – 29 July 1869), born to John and Sophia Jukes at Summer Hill, Birmingham, England, was a renowned geologist, author of several geological manuals and served as a naturalist on the expeditions of (under the command of Francis Price Blackwood). Correspondents and friends addressed him as Beete Jukes. Early life Jukes was born at Summer Hill, near Birmingham, on 10 October 1811. He was educated at Wolverhampton, King Edward's School, Birmingham and St John's College, Cambridge. At Cambridge Jukes studied geology under Professor Adam Sedgwick. Between 1839 and 1840, Jukes geologically surveyed Newfoundland. A book he wrote, ''Excursions In and About Newfoundland During the Years 1839 and 1840'', bore the fruit of what he had discovered and learned while he surveyed. He returned to England at the end of 1840, and in 1842 sailed as a naturalist on board the corvette HMS ''Fly'' to participate in the surveying and charting expeditions to survey ...

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 Stutc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

HMS Fly (1831)
HMS ''Fly'' was an 18-gun sloop of the Royal Navy. She was responsible for the exploration and charting of much of Australia's north-east coast and nearby islands. She was converted to a coal hulk in 1855 and broken up in 1903. Design and construction ''Fly'' was a development of the designed by Professor Inman of the School of Naval Architecture. She was long on the gundeck and at the keel. She had a beam of overall, and a hold depth of , giving her a tonnage of 485 69/94 bm. Her armament was made up of sixteen 32-pounder carronades and a pair of 9-pounder bow chasers.Winfield (2004), p. 120 ''Fly'' and her three sister ships ''Harrier'', ''Argus'' and ''Acorn'' were ordered on 30 January 1829. She was laid down in November 1829 and launched from Pembroke Dockyard on 25 August 1831. ''Argus'' and ''Acorn'' were cancelled on 27 April 1831, leaving ''Fly'' as the lead ship of a class of two.
