With each step you take, whether it's outside your back door, at the edge of a nearby pond, or along a path in a national park, you may be setting down your foot in the same place that a dinosaur once did. Just imagine, dinosaurs roaming the same earth we live on today! What an amazing place our planet must have been during the time of those mighty creatures. There were enormous plant-eating dinosaurs, perhaps gathered in herds, grazing in a forest-surrounded meadow. And there were packs of small but fast and smart meat-eating dinosaurs that searched for an opportunity to attack their prey. And there was the ultimate predator in the Tyrannosaurus rex, causing other dinosaurs to flee wherever he went. The Fact Atlas series welcomes you to the world of dinosaurs, vanished now but for the efforts of scientists, museums, and your own imagination. With a little help from this fact-filled dinosaur book, the prehistoric world comes alive with dinosaurs big and small, scary and just plain fascinating. This book offers a history of dinosaurs that challenges young readers to question and research what these prehistoric creatures were really like and why. Illustrations accompany dino statistics to help kids build the closest possible understanding to what it was like when dinosaurs roamed the earth.
