Plateosaurus was a prosauropod, from 220 million years ago. It lived at the same time as Coelophysis, however, it was too big to be threatened by it.
Length: 8 metres
Height: 4 metres
Weight: 2 tonnes
Plateosaurus was omnivorous - it ate plants and meat. Meat, however, only made up a small part of Plateosaurus' diet - it was mostly plants. Plateosaurus stood on its hind limbs to reach tree branches.
More famously found in Iguanodon, Plateosaurus also had a thumb spike for fending off predators. The spike could also be used to pull up roots.
