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.

This book tells the story of Tylosaurus, which swam in the prehistoric seas between 87 and 82 million years ago. It was a fierce marine reptile that used its sharp teeth and huge jaws to feed on sharks and other marine reptiles, such as plesiosaurs, as well as fish. A Tylosaurus could grow as long as 50 feet and was a superb swimmer.

This book tells the story of Ankylosaurus. This armored beast looked like a walking tank. It lived during the Cretaceous period between 100 and 65 million years ago and fed on plant material. At the end of its tail grew a bony club that it used to protect itself.
