Finding Out About Dinosaurs, the second book in the "Science Explorers" series, takes a fresh look at some of the most mysterious and popular creatures to ever walk the earth. What makes dinosaurs harder to study than any other animal in the world? For one thing, they've been extinct for millions of years. No one has ever seen a living dinosaur. Every picture, model and computer graphic of a dinosaur is based on how scientists think these animals would have looked, sounded and acted. As these perceptions are constantly changing, scientists find more and different ways to study these fascinating creatures. From the eggs they laid, to their dung and other fossilized remains, dinosaurs have left a trail of evidence that tells us how they lived, what they ate, how they took care of their babies and even how they died. Full of intriguing facts, photographs and illustrations Finding Out About Dinosaurs is an entertaining and information-packed guide to the ever-expanding world of the "terrible lizard." Each chapter opens with a dinosaur profile, including Sauropods, Hadrosaurs, Ceratopsians, Coelurosaurs and Tyrannosaurs. Young readers will learn how dinosaur bones are discovered, what secrets dinosaur dung can reveal, how new species are identified as well as how dinosaur groups spread from one part of the globe to another. Author Elin Kelsey profiles researchers who are using exciting new approaches to learn more about this incredibly diverse group of animals.
