The name thecodont is Greek for "socket-tooth", referring to the fact that thecodont teeth were set in sockets in the jawbones; an archosaurian characteristic that was inherited by the dinosaurs. While the taxon Thecodontia is obsolete, the term thecodont remains in use as an anatomical description of teeth in bony sockets; in addition to ...
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. [18]
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 ...
Ancestor of triceratops likely marched from Asia to North America via prehistoric land bridge, scientists say
The condition of having deep alveoli is known as thecodont, and is present throughout Archosauria, including dinosaurs. Most squamates , on the other hand, show the pleurodont condition, where the teeth are fused to the inner sides of the jaw bones, or the acrodont dentition , in which the teeth are fused to the top of the jaw bones without ...
While there are more than 200 species of cycads, only one is native to Florida, and only a couple are popular landscaping plants in our area.
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 ...
