Thecodontosaurus is the earliest known member of the dinosaur family called the prosauropods that many scientists believe became the huge long-necked herbivorous (plant eating) dinosaurs called sauropods. It was very small compared to the later giant plant eaters. Not a lot is known about this small dinosaur as very little of it was found. Thecodontoaurus, being such an early dinosaur, did not look very different from early meat-eaters - in fact, they may have all been related! It wasn't until later in the Triassic period that plant eaters got bigger and began to walk on four legs instead of two.

This small dinosaur is another victim of WWII. The type specimen and other material attributed to this dinosaur were destroyed by Nazi bombs in 1940. Fossils found in South Africa, North America and Australia are believed to potentially be the same genus. Again, as this was such an early dinosaur, it provides evidence of early dinosaur migration.
