Fossilised footprints give away how fast dinosaurs could walk and run.

The dinosaurs soon run amok.

The dinosaur ran on its hind legs and probably had rather small arms, he said in a telephone interview.

Parasaurolophus (Paras) - These quick orange dinosaurs run faster than the velociraptor.

Challenge mode is a single-player mode in which the dinosaur must run through levels to the dino sanctuary.

They studied trackways, fossil footprints left in mud, and concluded that dinosaurs ran as fast as a man; such activity implied warm blood.

And then, with hoots and cries that echoed in the dark cavernous space, all the dinosaurs wheeled and ran, heading down the concrete tunnel, into the darkness beyond.

The film takes place mostly on an island on which dinosaurs run free, though not for long.

What the prints cannot show is why the dinosaur was running.

Plants would die, large plant-eating dinosaurs would run out of food and die too, carnivorous dinosaurs would quickly follow.
