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 While the taxon Thecodontia is obsolete, the term thecodont remains in use as an anatomical description of teeth in bony sockets; in addition to ...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]
Thecodont dentition is a morphological arrangement in which the base of the tooth is completely enclosed in a deep socket of bone, as seen in crocodilians, dinosaurs and mammals, and opposed to acrodont and pleurodont dentition seen in squamate reptiles. [1] Notably, this appears to be the ancestral tooth condition in Amniota. [2]
Paleontologists estimated the dinosaur reached a height of 5-6.5 metres at the hip and 25-30 metres in length, making it as long as a basketball court and as tall as a two storey building.
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 dinosaur is courtesy of Mission Jurassic, a years-long project for which the museum has leased a plot of land outside Cody, Wyoming, in the Big Horn Basin. There, paleontologists from the ...
The dinosaur fossil, comprising 149 bones, was discovered on the Isle of Wight in 2013 and is the most complete skeleton found in the UK in more than a century, the research published in the ...
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 ...
