4 - 8 years. Long ago, dinosaurs ruled the Earth. Then, suddenly, they died out. For thousands of years, no one knew these giant creatures had ever existed. Then people began finding fossils -- bones and teeth and footprints that had turned to stone. Today, teams of experts work together to dig dinosaur fossils out of the ground, bone by fragile bone. Then they put the skeletons together again inside museums, to look just like the dinosaurs of millions of years ago. Paperback. 32 pages.

What is a fossil? Sometimes it's the imprint of an ancient leaf in a rock. Sometimes it's a woolly mammoth, frozen for thousands of years in the icy ground. Sometimes it's the skeleton of a stegosaurus that has turned to stone. A fossil is anything that has been preserved, one way or another, that tells about life on Earth. But you can make a fossil, too - something to be discovered a million years from now - and this book will tell you how.
