Dinosaurs were the ultimate prehistoric survival machines, ruling the Earth for 120 million years. The Cretaceous period spawned dinosaurs of all sizes. No creatures since can match the carnivorous dinosaurs' combination of speed, eyesight, brainpower and razor-sharp weapons. Combining advanced 3D graphics and leading-edge anatomy and paleontology, this episode explores the biology that made these animals such incredible purveyors of terror.
