Walking with Dinosaurs is the world's first natural history of dinosaurs. Using leading-edge computer technology and animatronics, this epic series shows dinosaurs as never before - it lets us travel back in time to watch living, breathing dinosaurs in their natural habitat. Tracing the 160-million-year history of dinosaurs, from their first appearance to their abrupt demise, Walking with Dinosaurs makes that distant world seem just as if it existed today.
Set in the mid Triassic, the world is still recovering from a massive extinction that millions of years before wiped out 95 percent of life. Across most of the Earth lie vast deserts but near the poles the weather is monsoonal. Here life is rebuilding the diversity that once existed. The program follows a small group of animals in a river valley through the dry season.
By the late Jurassic, dinosaurs dominated the globe and the most widespread group of all were the sauropods. These long-necked herbivores were giants even among dinosaurs weighing between 20 and 70 tons. This single program spans 12 years as we follow the hatching of a tiny Diplodocus through her struggle for survival until she reaches maturity and mates for the first time, completing the circle of life.
For all the successes of dinosaurs on land, they never made it into the sea - that is the realm of an entirely different group of reptiles, no less successful and no less awesome. The Jurassic sea boasts the largest carnivore on the planet: Liopleurodon, at 25 meters this monster was the same size as a blue whale but armed with teeth that were a quarter of a meter long. And Ophthalmosaurus - the fastest animal in the sea with huge eyes for night time hunting.
On a deserted beach lies the dead body of a gigantic pterosaur, an Ornithocheirus - with wingspans of up to 13 meters, these were the largest flying creatures ever. There is no sign of why this one died but over the course of the program it is revealed how this King of the Sky met his end after undertaking an epic flight to find a mate. During his journey the incredible diversity of life in the Early Cretaceous is revealed.
Throughout the entire time of the dinosaurs there were no ice caps on the poles. In the mid Cretaceous thick forests covered Antarctica. Although the climate here was warm, during the winter the sun would set completely for two months and then for the first time in their history dinosaurs would have faced ice and frost. The animals that lived here evolved to cope with what was, by dinosaur standards, the most extreme of environments.
After 160 million years of dominating life on Earth the dinosaurs appear as vigorous as ever. Tyrannosaurus rules over plains full of herds of horned and duck-billed dinosaurs. Yet closer study reveals there are hidden stresses and the rich ecosystem hides problems. Volcanic activity is high and disease and sterile eggs common. The central character in the program is a female Tyrannosaur that is trying to raise a new brood of chicks.
