Thecodontosaurus ("socket-tooth lizard") is a genus of herbivorous basal sauropodomorph dinosaur that lived during the late Triassic period (Carnian? age). [2] Its remains are known mostly from Triassic "fissure fillings" in South England. Thecodontosaurus was a small bipedal animal, about 2 m (6.5 ft) long. It is one of the first dinosaurs to ...
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.

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 While the taxon Thecodontia is obsolete, the term thecodont remains in use as an anatomical description of teeth in bony sockets; in addition to ...
New research shows that ants have been farming fungi for 66 million years — thanks in part to the asteroid that fueled the demise of the dinosaurs. When a massive asteroid wiped out the ...
An adult bee hummingbird, the smallest known dinosaur. The smallest dinosaur known is the bee hummingbird, [158] with a length of only 5 centimeters (2.0 in) and mass of around 1.8 g (0.063 oz). [159] The smallest known non-avialan dinosaurs were about the size of pigeons and were those theropods most closely related to birds. [160]

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 ...
