This book tells the story of Pteranodon. During the late Cretaceous period, between 89 and 80 million years ago, one of the largest flying reptiles to exist flew in the skies. Its large wingspan and short tail made it very agile so it could turn or dive quickly. Its head could measure nearly six feet (two meters) long and on the back of its head grew a magnificent crest.
