220 million years ago, as dinosaurs were beginning their domination of Earth, another group of reptiles was about to make an extraordinary leap. Pterosaurs were taking control of the skies. The story of how and why these mysterious creatures took to the air is more fantastical than any fiction. In Flying Monsters, Sir David Attenborough sets out to uncover the truth about the enigmatic pterosaurs whose wingspans of up to 40 feet were equal to that of a modern day jet plane. The central question and of the greatest mysteries in palaeontology is how and why did pterosaurs fly. How did creatures the size of giraffes defy gravity and soar through prehistoric skies? Attenborough starts to unravel one of science’s more enduring mysteries, discovering that the marvel of pterosaur flight has evolutionary echoes that resonate even today.
