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 ...
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 ...
Barilium is a genus of iguanodontian dinosaur which was first described as a species of Iguanodon (I. dawsoni) by Richard Lydekker in 1888, the specific epithet honouring the discoverer Charles Dawson, who collected the holotype during the 1880s. [1] Middle dorsal vertebra. In 2010 it was reclassified as a separate genus by David Norman.
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.
Hypselospinus lived during the lower Valanginian stage, around 140 million years ago. [2][3] A contemporary of Barilium (also once thought to be a species of Iguanodon), Hypselospinus was a lightly built iguanodontian estimated at 6 metres (19.7 ft) long. [4] The species Iguanodon fittoni was described from remains discovered in 1886 alongside ...
Bartholomai & Molnar, 1981. Muttaburrasaurus was a genus of herbivorous iguanodontian ornithopod dinosaur, which lived in what is now northeastern Australia sometime between 112 and 103 million years ago [1] during the early Cretaceous period. It has been recovered in some analyses as a member of the iguanodontian clade Rhabdodontomorpha. [2]
Dinosaurs were “the best sort of monsters — big, scary, and, best of all, dead,” writes Dolnick. ... Mantell realized that his “large fossil teeth looked strikingly like the iguana’s ...
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 ...
