Gee, a distinguished science writer, has teamed up with Luis V. Rey, a leading illustrator, to present a modern-day field guide to the dinosaurs of the Mesozoic era. More than 50 species are covered, from the giant Tyrannosaurus to the flying Pterodactyl, and each is described and illustrated in full colour. Illustrations show gait, eggs or mature specimens and other distinguishing features, and text contains a summary of the current state of knowledge about habits, behaviour, life-styles and range.
