National Geographic: Flying Monsters

Two hundred twenty million years ago, dinosaurs were beginning their domination of the Earth. But another group of reptiles was about to make an extraordinary leap: Pterosaurs were taking control of the skies, and the story of how and why these mysterious creatures took to the air is more fantastic than fiction.

In Flying Monsters 3-D, Sir David Attenborough, the world's leading naturalist, sets out to uncover the truth about the enigmatic pterosaurs, whose wingspans of more than 40 feet were equal to that of a modern jet plane. Attenborough works with scientists and engineers to understand the incredible story of their evolution. It's a story told through a tour of diverse habitats such as Big Bend National Park in Texas, Lyme Regis in Britain, and China's remote Liaoning Province, as well as through stunning recreations of the prehistoric world of the pterosaur.
