No human has ever seen a dinosaur . . . and no human has ever seen a dinosaur book like this one! We all think we know what dinosaurs looked like, but how can we be sure? From fossils to fur, skeletons to skin color, Professor Potts leads a colorful investigation into what we know and what we can only guess, and encourages readers to make some guesses of their own. You will never think about dinosaurs in the same way again.
