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.
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 ...
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.
A contemporary of Hypselospinus (also once thought to be a species of Iguanodon), Barilium was a robust iguanodontian estimated at 8 metres (26 feet) long. [6] Barilium is separated from Hypselospinus on the basis of vertebral and pelvic characters, size, and build. [6] For example, Barilium was more robust than Hypselospinus, with large ...
Mantellisaurus is a genus of iguanodontian dinosaur that lived in the Barremian and early Aptian ages of the Early Cretaceous Period of Europe. Its remains are known from Belgium (Bernissart), England, Spain and Germany. The type and only species is M. atherfieldensis.
The previous record for the smallest non-avian dinosaur egg, according to Guinness World Records, measures 45-by-20 millimeters (about 1.77-by-0.79 inches). Discovered in Japan's Tamba City, this ...
Estimated size of Iguanacolossus. Iguanacolossus is a large, robust iguanodontid, probably reaching 9 m (30 ft) long and weighing 5 t (11,000 lb) in body mass. [3] [1] According to McDonald and colleagues, Iguanacolossus differs from other iguanodontians in having a contact surface for supraoccipital on caudomedial process of squamosal curved in caudal view, cranial pubic process with concave ...
