Becklespinax
''Altispinax'' (; "with high spines") is a genus of large predatory theropod dinosaur from the Early Cretaceous period (Valanginian, 140 to 133 million years ago) of what is now the Wadhurst Clay Formation of East Sussex, England. History Probably during the early 1850s, fossil collector Samuel Husbands Beckles discovered some nodules with dinosaur bones in a quarry near Battle, East Sussex. These he sent to palaeontologist Richard Owen, who reported them in 1856.Owen, R., 1856, ''Monograph on the fossil Reptilia of the Wealden Formation. Part IV''. Palaeontographical Society Monographs 10, 26 pp Owen had a lithograph made by Joseph Dinkel of the main specimen, a series of three back vertebrae with very tall spines, whose image was also shown in an 1884 edition of an 1855 volume of his standard work on British fossil reptiles, leading to the misunderstanding the fossils had been recovered close to 1884. Owen, who referred the specimens to '' Megalosaurus bucklandii'', thought t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Megalosaurus Dunkeri
''"Megalosaurus" dunkeri'' is a nomen dubium, dubious species of theropod dinosaur, known only from a single tooth. History ''"M." dunkeri'' was originally named and described by Wilhelm Dames on 16 December 1884 during a lecture.Dames, W.B. (1885). "Vorlegung eines Zahnes von ''Megalosaurus'' aus den Wealden des Deisters", ''Sitzungsberichte der Gesellschaft naturforschender Freunde zu Berlin, Jahrbuch 1884'', 36: 186-188 A synopsis of the lecture was actually published in 1885, but because this was in the form of an 1884 yearbook, the latter date is usually given. However, some sources indicate 1887 as the year of publication and designate the species as a ''"Megalosaurus" dunkeri'' Dames vide Koken 1887, because in that year, the type specimen, a single tooth, was again described and also illustrated in a publication by Ernst Koken. The specific name (zoology), specific name honours paleontologist Wilhelm Dunker, who, many years earlier, had discovered the tooth on the D ...

Megalosaurus Bucklandii
''Megalosaurus'' (meaning "great lizard", from Greek , ', meaning 'big', 'tall' or 'great' and , ', meaning 'lizard') is an extinct genus of large carnivorous theropod dinosaurs of the Middle Jurassic period (Bathonian stage, 166 million years ago) of Southern England. Although fossils from other areas have been assigned to the genus, the only certain remains of ''Megalosaurus'' come from Oxfordshire and date to the late Middle Jurassic. ''Megalosaurus'' was, in 1824, the first genus of non-avian dinosaur to be validly named. The type species is ''Megalosaurus bucklandii'', named in 1827. In 1842, ''Megalosaurus'' was one of three genera on which Richard Owen based his Dinosauria. On Owen's directions a model was made as one of the Crystal Palace Dinosaurs, which greatly increased the public interest for prehistoric reptiles. Over fifty other species would eventually be classified under the genus; at first, this was because so few types of dinosaur had been identified, but the p ...

Samuel Beckles
Samuel Husbands Beckles (12 April 1814, in Barbados – 4 September 1890, in Hastings) was a Bajan/English 19th-century lawyer, turned dinosaur hunter, who collected remains in Sussex and the Isle of Wight. In 1854 he described bird-like trackways that he thought could have been made by dinosaurs, which he later identified as probably those of ''Iguanodon'' in 1862. In 1857, following the discovery of a mammal jaw at Durlston Bay, he directed a major excavation that became known as 'Beckles' Pit', removing five metres of overburden over a 600 square metre area, one of the largest ever scientific excavations. The collection of mammal fossils that resulted is now mainly held at the Natural History Museum. He discovered the small herbivorous dinosaur ''Echinodon''. The only known species ''Echinodon becklesii'', the mammal '' Plagiaulax becklesii'' and the dinosaur '' Becklespinax'' were named in his honour (although the last of these is now known as '' Altispinax'').

Hastings Bed Group
The Wealden Group, occasionally also referred to as the Wealden Supergroup, is a group (a sequence of rock strata) in the lithostratigraphy of southern England. The Wealden group consists of paralic to continental (freshwater) facies sedimentary rocks of Berriasian to Aptian age and thus forms part of the English Lower Cretaceous. It is composed of alternating sands and clays. The sandy units were deposited in a flood plain of braided rivers, the clays mostly in a lagoonal coastal plain.Jackson (2008) The Wealden Group can be found in almost all Early Cretaceous basins of England: its outcrops curve from the Wessex Basin in the south to the Cleveland Basin in the northeast. It is not found in northwest England and Wales, areas which were at the time tectonic highs where no deposition took place. The same is true for the London Platform around London and Essex. Offshore, the Wealden Group can reach a thickness of 700 metres. The terms ''Wealden'' and ''Wealden facies'' are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acrocanthosaurus
''Acrocanthosaurus'' ( ; ) is a genus of carcharodontosaurid dinosaur that existed in what is now North America during the Aptian and early Albian stages of the Early Cretaceous, from 113 to 110 million years ago. Like most dinosaur genera, ''Acrocanthosaurus'' contains only a single species, ''A. atokensis''. Its fossil remains are found mainly in the U.S. states of Oklahoma, Texas, and Wyoming, although teeth attributed to ''Acrocanthosaurus'' have been found as far east as Maryland, suggesting a continent wide range. ''Acrocanthosaurus'' was a bipedal predator. As the name suggests, it is best known for the high neural spines on many of its vertebrae, which most likely supported a ridge of muscle over the animal's neck, back, and hips. ''Acrocanthosaurus'' was one of the largest theropods, with the largest known specimen reaching in length and weighing approximately . Large theropod footprints discovered in Texas may have been made by ''Acrocanthosaurus'', although there ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Benjamin Waterhouse Hawkins
Benjamin Waterhouse Hawkins (8 February 1807 – 27 January 1894) was an English sculptor and natural history artist renowned for his work on the life-size models of dinosaurs in the Crystal Palace Park in south London. The models, accurately made using the latest scientific knowledge, created a sensation at the time. Hawkins was also a noted lecturer on zoological topics. Education and early career Benjamin Waterhouse Hawkins was born in Bloomsbury, London on 8 February 1807, the son of Thomas Hawkins, an artist, and Louisa Anne Waterhouse, the daughter of a Jamaica plantation family of apparent Catholic sympathies. He studied at St. Aloysius College, and learned sculpture from William Behnes. At the age of 20, he began to study natural history and later geology. He contributed illustrations to ''The Zoology of the Voyage of HMS Beagle''. During the 1840s, he produced studies of living animals in Knowsley Park, near Liverpool for Edward Stanley, 13th Earl of Derby. The ...

Crystal Palace Dinosaurs
The Crystal Palace Dinosaurs are a series of sculptures of dinosaurs and other extinct animals, incorrect by modern standards, in the London borough of Bromley's Crystal Palace Park. Commissioned in 1852 to accompany the Crystal Palace after its move from the Great Exhibition in Hyde Park, they were unveiled in 1854 as the first dinosaur sculptures in the world. The models were designed and sculpted by Benjamin Waterhouse Hawkins under the scientific direction of Sir Richard Owen, representing the latest scientific knowledge at the time. The models, also known as Dinosaur Court, were classed as Grade II listed buildings from 1973, extensively restored in 2002, and upgraded to Grade I listed in 2007. The models represent 15 genera of extinct animals, only three of which are true dinosaurs. They are from a wide range of geological ages, and include true dinosaurs, ichthyosaurs, and plesiosaurs mainly from the Mesozoic era, and some mammals from the more recent Cenozoic era. Today ...

London - Crystal Palace - Victorian Dinosaurs 1
London is the capital and largest city of England and the United Kingdom, with a population of just under 9 million. It stands on the River Thames in south-east England at the head of a estuary down to the North Sea, and has been a major settlement for two millennia. The City of London, its ancient core and financial centre, was founded by the Romans as '' Londinium'' and retains its medieval boundaries.See also: Independent city § National capitals The City of Westminster, to the west of the City of London, has for centuries hosted the national government and parliament. Since the 19th century, the name "London" has also referred to the metropolis around this core, historically split between the counties of Middlesex, Essex, Surrey, Kent, and Hertfordshire, which largely comprises Greater London, governed by the Greater London Authority.The Greater London Authority consists of the Mayor of London and the London Assembly. The London Mayor is distinguished from the L ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Early Cretaceous
The Early Cretaceous ( geochronological name) or the Lower Cretaceous (chronostratigraphic name), is the earlier or lower of the two major divisions of the Cretaceous. It is usually considered to stretch from 145 Ma to 100.5 Ma. Geology Proposals for the exact age of the Barremian-Aptian boundary ranged from 126 to 117 Ma until recently (as of 2019), but based on drillholes in Svalbard the defining early Aptian Oceanic Anoxic Event 1a (OAE1a) was carbon isotope dated to 123.1±0.3 Ma, limiting the possible range for the boundary to c. 122–121 Ma. There is a possible link between this anoxic event and a series of Early Cretaceous large igneous provinces (LIP). The Ontong Java-Manihiki-Hikurangi large igneous province, emplaced in the South Pacific at c. 120 Ma, is by far the largest LIP in Earth's history. The Ontong Java Plateau today covers an area of 1,860,000 km2. In the Indian Ocean another LIP began to form at c. 120 Ma, the Kerguelen P ...

Richard Lydekker
Richard Lydekker (; 25 July 1849 – 16 April 1915) was an English naturalist, geologist and writer of numerous books on natural history. Biography Richard Lydekker was born at Tavistock Square in London. His father was Gerard Wolfe Lydekker, a barrister-at-law with Dutch ancestry. The family moved to Harpenden Lodge soon after Richard's birth. He was educated at Trinity College, Cambridge, where he took a first-class in the Natural Science tripos (1872). In 1874 he joined the Geological Survey of India and made studies of the vertebrate palaeontology of northern India (especially Kashmir). He remained in this post until the death of his father in 1881. His main work in India was on the Siwalik palaeofauna; it was published in ''Palaeontologia Indica''. He was responsible for the cataloguing of the fossil mammals, reptiles, and birds in the Natural History Museum (10 vols., 1891). He named a variety of taxa including the golden-bellied mangabey; as a taxon authority he is nam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oskar Kuhn
Oskar Kuhn (7 March 1908, Munich – 1990) was a German palaeontologist. Life and career Kuhn was educated in Dinkelsbühl and Bamberg and then studied natural science, specialising in geology and paleontology, at the University of Munich, from which he received his D. Phil. in 1932. He worked in the University of Munich Geological Institute, among other things on the ''Fossilium Catalogus'' (Catalogue of Fossils), and then in 1938 on a stipend from the Deutsche Forschungsgemeinschaft, moved to the University of Halle, where he worked on the Geiseltal fossils. In 1939 he achieved his Habilitation with a thesis on the Halberstadt Keuper fauna, and in 1940 was named Privatdozent in geology and paleontology. Informed by his Catholic religion, Kuhn was an exponent of idealistic morphology: he viewed evolution as operating only within predetermined morphological classes. In 1943 he declared, "The theory of descent has collapsed." After a political conflict with his mentor, Johan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
