Temporal range: Triassic period
Riley & Stuchbury, 1836
Thecodontosaurus (meaning "socket-toothed lizard") was a very early dinosaur that lived during the late Triassic period, a time when the Earth was relatively warm and much of the land was dry and desert-like. This was around the time that the dinosaurs were just starting to appear.
Description[change | edit source]
Fossils of Thecodontosaurus have been found in southwest England (near Bristol) and Wales, which were probably dry and desert-like when Thecodontosaurus lived. Thecodontosaurus was named by Morris in 1843, but was first described by H. Riley and S. Stutchbury in 1836.
