Dinosaur teeth have been studied since 1822 when Mary Ann Mantell (1795-1869) ... essential to revealing the most important aspects of dinosaur dental anatomy.
In dinosaurs, the anatomy of the braincase is conservative, but for this reason can be used to infer relationships of a group when other skeletal features underwent changes so profound that their origins can no longer be traced. The braincase may also allow for reconstructing the brain and inner ear, with inferences on senses and intelligence. [20]
Very young specimens show simple cup shapes occlusion zones, or areas where the teeth contact one another in chewing, whereas in adulthood there is a "dual function" arrangement with two distinct areas of different tooth wear. This change during growth may have helped transition from a diet of softer plants when young to more tough and fibrous ...
Reisz developed this hypothesis by studying dental anatomy and living relatives of dinosaurs. Lips protect teeth from drying out and they help preserve the enamel.
Dimetrodon (/ d aɪ ˈ m iː t r ə ˌ d ɒ n / ⓘ [1] or / d aɪ ˈ m ɛ t r ə ˌ d ɒ n /; [2] lit. ' two measures of teeth ') is an extinct genus of sphenacodontid synapsid tetrapods that lived during the Cisuralian age of the Early Permian period, around 295–272 million years ago.
Estimations of the tooth count of Carcharodontosaurus vary, but a recent estimate of 30 dentary, 8 premaxillary, and 24 maxillary teeth for a total of 62 teeth was made. [56] Carcharodontosaurid teeth are some of the largest of any dinosaur group, with a maxillary tooth from SNSB-BSPG 1922 X 46 being 6.8 centimetres (2.7 in) tall and 3.5 ...
The Istiodactylidae had recurved teeth for eating meat. Ctenochasmatidae used combs of numerous needle-like teeth for filter feeding; Pterodaustro could have over a thousand bristle-like teeth. Dsungaripteridae covered their teeth with jawbone tissue for a crushing function. If teeth were present, they were placed in separate tooth sockets. [27]
Dimorphodon (/ d aɪ ˈ m ɔːr f ə d ɒ n / dy-MOR-fə-don) is 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.
