A long, long, time ago, before television, before cars, and airplanes, and bicycles.... Before sailing ships and pirates, knights and castles, bows and arrows.... Before humans first set foot on Earth.... Before grass and flowers grew, before the first birds flew through the ancient skies, the savage, untamed world was ruled by the most astonishing creatures: the dinosaurs. Using the state-of-the-art computer graphics and natural history photography from the Discovery Channel's awesome television production "Walking with Dinosaurs," this unique book offers children of all ages the chance to come face-to-face with these prehistoric creatures. All young readers have to do is put on the enclosed 3-D glasses and watch these amazing images leap off the page. You'll feel like you can reach out and touch them!
