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 ...
Giganotosaurus (/ ˌɡɪɡəˌnoʊtəˈsɔːrəs / GIG-ə-NOH-tə-SOR-əs[2]) is a genus of theropod dinosaur that lived in what is now Argentina, during the early Cenomanian age of the Late Cretaceous period, approximately 99.6 to 95 million years ago. The holotype specimen was discovered in the Candeleros Formation of Patagonia in 1993 and is ...
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 ...

Pterodactylus (Rhamphorhynchus) macronyx (Buckland, 1829) Dimorphodon (/ daɪˈmɔːrfədɒn / dy-MOR-fə-don) was a genus of medium-sized pterosaur from Europe during the early Jurassic Period (about 201-191 million years ago). [1] It was named by paleontologist Richard Owen in 1859. Dimorphodon means "two-form tooth", derived from the Greek ...
Since dinosaur teeth are often found with well-preserved enamel, Reisz concluded that dinosaurs likely had a protective set of lips to hydrate the gums. Reisz also examined the gums, teeth and ...
Diagram comparing the holotype tooth (first from left) with other spinosaurid teeth from Asia Fossil theropod teeth are typically identified by attributes such as the proportions, size, and curvature of the crown , as well as the presence and/or shape of the denticles (serrations). [ 39 ]
