One hundred million years ago, the skies were filled with enormous flying reptiles. With wings spans up to nearly forty feet, pterosaurs were the dominant life form on earth. The relationship of these giants of the air to dinosaurs and to other reptiles, their varied appearance and lifestyles, their evolution and extinction, the fossil discoveries that scientists are continually making throughout the world--all are depicted in this beautifully illustrated, accessible book for young scientists and their parents and teachers. Once again, acclaimed science author Caroline Arnold and meticulous watercolorist Laurie Caple have teamed up to create an eye-opening look at an amazing group of prehistoric animals and what the world was like when these incredible creatures ruled the skies of earth.
