This book tells the story of Stegosaurus, who lived during the Jurassic period between 155 and 145 million years ago. It had large bony plates, which it probably used for temperature control, soaking up the sun, or catching a cool breeze.

"Describes the features of Triceratops and Stegosaurus, and how they may have battled each other in prehistoric times"--Provided by publisher.

Learn about the Stegosaurus, what it ate and where it was found.

Oona finds a giant egg and brings it back to West Wog to care for it, and see what hatches--but others in the cave want to claim her egg, particularly the nasty kid Bruce Brute, and when the baby stegosaurus hatches it will have to choose who it wants to live with.

In this adventure, Jamie and Tess find themselves caught in a terrible storm. During the chaos, a stegosaurus egg is swept away downriver. It's up to Jamie and Tess to recover the egg and return it to its mother before it's too late!--
