The theropods were a diverse group of dinosaurs. They walked on two legs, were mostly meat-eaters, and all had three-toed limbs.

Theropods all had hollow bones, something they have in common with their descendants, modern birds.

They include the iconicT. rex, as well asVelociraptor, Spinosaurus andCompsognathus, of Jurassic Park fame.
