This did not change when Richard Owen coined the term Dinosauria in 1842, because Owen did not recognise Thecodontosaurus as a dinosaur; in 1865, he assigned it to the Thecodontia. It was not until 1870 that Thomas Huxley became the first person to understand that it was a dinosaur, though referring it incorrectly to the Scelidosauridae . [ 19 ]
Thecodontia (meaning 'socket-teeth'), now considered an obsolete taxonomic grouping, was formerly used to describe a diverse "order" of early archosaurian reptiles that first appeared in the latest Permian period and flourished until the end of the Triassic period. All of them were built somewhat like crocodiles but with shorter skulls, more ...
Thecodontosauridae is a family of basal sauropodomorph dinosaurs [1] that are part of the Bagualosauria, [2] known from fossil remains found exclusively in the Magnesian Conglomerate of Bristol, England, [3] which dates back to the Rhaetian stage of the Late Triassic (although it could be as old as the Norian stage of the Late Triassic and as young as the Hettangian stage of the Early Jurassic ...
This feature is responsible for the name "thecodont" (meaning "socket teeth"), [8] which early paleontologists applied to many Triassic archosaurs. [7] Additionally, non-muscular cheek and lip tissue appear in various forms throughout the clade, with all living archosaurs lacking non-muscular lips, unlike most non-avian saurischian dinosaurs.

Dinosaur classification began in 1842 when Sir Richard Owen placed Iguanodon, Megalosaurus, and Hylaeosaurus in "a distinct tribe or suborder of Saurian Reptiles, for which I would propose the name of Dinosauria." [1] In 1887 and 1888 Harry Seeley divided dinosaurs into the two orders Saurischia and Ornithischia, based on their hip structure. [2]
The dentition of Cymbospondylus is generally thecodont, meaning that the tooth roots are deeply cemented into the jawbone. However, not all species share the same robustness in terms of their dental implantation. C. petrinus has a particular form of thecodont dentition, its teeth appearing to be fused at the bottom of the alveoli. [70]
A new plant-eating dinosaur species discovered in Japan has been named after gnomes for its small size.. The animal, measuring about 3ft in length and 10kg in weight, was an ancestor of the ...
The word "interdental" is a combination of "inter" + "dental" (meaning "between the teeth") which originated in approximately 1870. [2] In paleobiology , the presence or absence of the interdental plate can determine the place of an animal in the evolutionary scale , and paleontologists use the interdental plate when trying to classify a new ...
