Rampaging Allosaurus

As big and scary as Tyrannosaurus, Allosaurus was a fearsome predator. Follow an Allosaurus as it tracks its prey, and learn about other predators such as speedy, vicious Utahraptor and sly, crested Guanlong. Then meet Hypsilophodon, a small plant-eater that lived in large groups in burrows; Archaeopteryx, a feathered dinosaur capable of short gliding flights; and crocodile-like Steneosaurus.
