Children are born curious and dinosaurs are high on the list of fascination. This book is not about specific dinosaurs, but what it is like to be out on a dig: to experience what it feels like to hold a bone that belonged to a dinosaur dead for 100 million years. That’s 100,000,000 years. The allure of dinosaurs has never been stronger and the adventure of prospecting out in the field captures the imagination of middle school to young adult readers.
