"When Dinosaurs Ruled" takes viewers on a global discovery to the five "lost worlds" of Dinosaurs. We travel to excavation digs all over the planet in search of clues to the great beasts that once roamed the earth, seas and skies of long ago. "When Dinosaurs Ruled North America" joins leading paleontologists Bob Bakker and Jim Kirkland as they travel back in time to trace the rise and fall of the dinosaurs in America. From the western U.S. to Canada and Alaska, these scientists are finding fossils that paint the story of which dinosaurs roamed here and what their adversaries were. From the heavily-armoured Stegosaurus to the powerful flesh eaters, this is the story of the dinosaurs of North America.
