220 million years ago dinosaurs were beginning their domination of Earth. But 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.

It tells a story of a bird-monster from South America originally treated as god by Incas. Long believed to be extinct, due to genetical experiment gone awry its egg fossil hatches and the monster starts to search for females to impregnate.
