Iguanodon (/ ɪ ˈ ɡ w ɑː n ə d ɒ n / i-GWAH-nə-don; meaning 'iguana-tooth'), named in 1825, is a genus of iguanodontian dinosaur.While many species found worldwide have been classified in the genus Iguanodon, dating from the Late Jurassic to Early Cretaceous, taxonomic revision in the early 21st century has defined Iguanodon to be based on one well-substantiated species: I ...
Gideon Algernon Mantell MRCS FRS (3 February 1790 – 10 November 1852) was an English obstetrician, geologist and palaeontologist.His attempts to reconstruct the structure and life of Iguanodon began the scientific study of dinosaurs: in 1822 he was responsible for the discovery (and the eventual identification) of the first fossil teeth, and later much of the skeleton, of Iguanodon.
The holotype fossil, NHMUK PV R5764, was originally discovered by Reginald Walter Hooley in 1914 in the upper Vectis Formation of southern England and reported upon in 1917. He posthumously named it Iguanodon atherfieldensis in 1925. Atherfield is the name of a village on the southwest shore of the Isle of Wight where the fossil was found. [1]
Mary Ann Mantell (née Woodhouse; 9 April 1795 [1] – 20 October 1869 [2]) was a British fossil collector [3] and the wife of the British paleontologist Gideon Mantell.She is credited – although this is disputed – with the discovery of the first fossils of Iguanodon and provided several pen and ink sketches of the fossils for her husband's scientific description of the Iguanodon.
Curiously, it is Hylaeosaurus, from the Cretaceous of England, not Iguanodon, that most resembles the giant iguana stereotype of early ideas of dinosaurs. The Hylaeosaurus in reality is much like Ankylosaurus – smallish quadrupedal herbivore with a knobbled armoured back, and spines along its sides. Hawkins's depiction is of a large Iguana ...
Iguanodontidae is a family of iguanodontians belonging to Styracosterna, a derived clade within Ankylopollexia. Characterized by their elongated maxillae, they were herbivorous and typically large in size. This family exhibited locomotive dynamism; there exists evidence for both bipedalism and quadrupedalism within iguanodontid species ...
Comptonatus was entered into a phylogenetic analysis using the dataset of the description of the contemporary Brighstoneus. [4] It was found to be in a clade with Iguanodon, Barilium, and Mantellisaurus, all from southern England, which has been termed the Iguanodontidae.
Goodrich Iguanodon. In the nineteenth century, this quarry was an important source of ragstone but the site is most famous for Gideon Mantell’s discovery of the fossilised bones of an Iguanodon in 1834. Explosives were regularly used to uncover fresh sources of ragstone but, on this occasion, bones were exposed and preserved by the quarry ...
