Plateosaurus adopts a threatening posture.Plateosaurus was a prosauropod that lived during the Triassic Period. Prosauropods were part of a larger group of dinosaurs, called the sauropodomorphs. This group also included the sauropods which rose to prominence in the Jurassic. Although Plateosaurus had a large, stocky body with a long neck and tail, it stood and walked on its hindlegs most of the time. Its powerful hindlegs had elongated upper foot bones, while its short but muscular arms each had a five-fingered hand with a large thumb-claw. Plateosaurus had a small skull with powerful jaws and rows of small, leaf-shaped, saw-edged teeth.

If it were ever attacked, Plateosaurus had fearsome claws on its thumbs, as well as claws on its other fingers and toes to defend itself with. It could also rise up on its hindlegs and swing its hefty tail at its attacker.

Fossil discoveries

In 1997, some fossil bones from Plateosaurus were discovered in rocks drilled from 2200 m (7200 ft) below the bed of the North Sea, making it the deepest-ever dinosaur find ever recorded.
