This programme takes us beyond the lush forests, roaring lions and the blazing sun of Africa to reveal the World's most remote and hard to reach dinosaur fossils known to exist. We follow paleontologist Paul Sereno and his team from the southern tip of Africa to the northern reaches of Morocco as we meet some of the most diverse dinosaurs to have roamed our World.

For a century, we've known the T-Rex as the King of Dinosaurs ... the largest meat-eater to ever walk the Earth. But two new dinosaur discoveries may change that forever. Beyond T-Rex goes from Morocco to Patagonia to unearth Giganotosaurus and Carcharadontosaurus, two newly found meat-eating giants that threaten to dethrone the tyrant lizard king. Their fossils raise many questions about the lifestyle, behaviour and evolution of the giant killer dinosaurs. We visit the excavation sites and re-create their world using state-of-the-art animation. By comparing the subtle differences in anatomy of these fearsome creatures, we contemplate which giant really was the King of Dinosaurs.

"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.

In the searing heat of Australia and frozen wastes of Antarctica, the dinosaurs that ruled these lands were the toughest creatures that ever lived. Follow a path of over 3000 footprints left in soft clay, proof that dinosaurs lived in the deadly Outback.

"When Dinosaurs Ruled South America" searches the rocky slopes of the Andes Mountains with paleontologist Martin Vince as he discovers evidence of the world's smallest dinosaurs. Learn about the geology of South America that, in turn, allowed for these small creatures to eventually evolve into the world's largest dinosaurs.
