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 ...
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 ...
Tenontosaurus was originally classified in the family Iguanodontidae, [1] although subsequent authors challenged this classification and proposed it actually belonged to Hypsilophodontidae. [3] Subsequent phylogenetic analyses have found Tenontosaurus to be intermediate in position between Hypsilophodon -like taxa and Iguanodon -like taxa, as a ...
Dinosaur tooth. Dinosaur teeth have been studied since 1822 when Mary Ann Mantell (1795-1869) and her husband Dr Gideon Algernon Mantell (1790-1852) discovered an Iguanodon tooth in Sussex in England. Unlike mammal teeth, individual dinosaur teeth are generally not considered by paleontologists to be diagnostic to the genus or species level for ...
Owenodon. Owenodon is a genus of iguanodontian dinosaur known from a partial lower jaw discovered in Early Cretaceous -age rocks of Dorset, United Kingdom, and possibly also Romania and Spain. The first and only definitive specimen was found in the Lulworth Formation of the Purbeck Limestone Group, dating to the middle Berriasian stage.
How this became our routine throughout the winter, like having dinner or brushing teeth. The suddenness and completeness of the emptiness was itself a presence. A gaping maw, created to devour spirit.
Lurdusaurus ("heavy lizard") is a genus of massive and unusually shaped iguanodont dinosaur from the Elrhaz Formation in Niger. It contains one species, L. arenatus. The formation dates to the Early Cretaceous, roughly 112 million years ago. Lurdusaurus has a highly atypical body plan for an iguanodont, with a small skull, long neck, rotund ...
Fluoride, a mineral that strengthens teeth and reduces the risk of cavities, has been added to drinking water since 1945 to promote good tooth health in children.
