Walking with Dinosaurs

A behind-the-scenes look at the science and technology behind the series.

Zoologist and adventurer Nigel Marven travels back in time on a prehistoric safari to find some of the most spectacular animals ever to live. This time Nigel has traveled back 100 million years to Cretaceous South America, during the true…

Nigel searches the early Mongolia deserts and forests for Therizinosaurus, who has massive and very long claws. On his journey, Nigel dashes across a nesting ground of Protoceratops into a forest ruled by Velociraptor and then into the…

Reptiles not only rule the seas, but the skies as well. This is the time of the pterosaurs, flying reptiles that dominate the Cretaceous skies. And at this point, none is as large as the massive Ornithocheirus, the largest pterosaur at…

In the mid-Cretaceous, Australia, Antarctica, and South America are still connected in one super continent. This is a time when the South Pole is a huge polar forest, where for five months of the year, the sun never sets. The Antarctic…

The year is 65.5 million BC, and the time is 11:59pm for the dinosaurs. Volcanic activity has begun to choke the land, and dinosaurs are suffering. Few eggs are hatching, poisoned by the toxins in the air. Dinosaurs are on the decline,…
