The Iguanodon (iguana-tooth) could stand up on its hind legs, like today’s kangaroos, in order to run fast and to feed on the foliage of tall trees. Its thumbs had the form of spines; these served as a defence against predatory dinosaurs. The young animals walked mainly on their powerful hind legs. The simultaneous occurrence of the Deinonychus suggests that the Iguanodon was one of its preferred animals of prey, although there is no fossil evidence of this.

The Deinonychus (terrible claw) was an agile, highly intelligent and skilful predator. It hunted in packs like wolves and killed its prey by tearing it open with the 20 cm long dagger-like, razor-sharp claws of its hind feet. Its jaws were armed with sharp teeth.
