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 ...
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.

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 ...
The thecodont condition was historically used to define a clade, the Thecodontia, which is now considered paraphyletic and thus obsolete. [7] angular The angular is a dermal bone of the lower jaw. In lateral view, it covers a larger area of the posteroventral region of the jaw, being located behind the dentary and below the surangular.
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 dictionary was edited by the honorary director general of the board Maulvi Abdul Haq who had already been working on an Urdu dictionary since the establishment of the Urdu Dictionary Board, Karachi, in 1958. [1] [2] [3] Urdu Lughat consists of 22 volumes. In 2019, the board prepared a short concise version of the dictionary in 2 volumes.
In contrast, Archosauromorphs possess a parasagittal gait, a reduction in their dermal girdle, a reduction and/or loss of the sternum, and a more thecodont dentition. Living lepidosauromorphs have retained an ectothermic (" cold blooded ") metabolism, unlike the ancestral condition in archosauromorphs.
