While the dinosaurs roamed the Earth, another species ruled the skies. These were the pterosaurs. They weren't birds, but flying reptiles. They were expert flyers, swooping, soaring, and gliding through prehistoric skies. They were magnificent hunters, too, diving for fish, snapping up insects in the air, or dining on baby dinosaurs. In this book readers will discover all about these awesome creatures, how they lived, how they hunted, and why they eventually died out.
