Walking with Dinosaurs - Season 1 - Eps 4: Giant Of The Skies
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 the time. We follow the final days of one such Ornithocheirus as he makes his way to the mating grounds, soaring over the lands ruled by dinosaurs.
