Book excerpt: Dinosaurs and Other Prehistoric Creatures explores the vanished world of these ancient animals. It descends through the different time periods in which they lived--Triassic, Jurassic, and Cretacious--and down from the flying reptiles that soared through the skies to the dinosaurs that roamed the ground and the predators that hunted in the planet's teeming, dangerous oceans. Each spread features bold, colorful, and eye-catching illustrations of the different dinosaur species, plus easy-to-digest, bite-sized factoids about the creatures.
