Book excerpt: You already know the mighty T-Rex and the Apatosaurus, but have you heard of the Baryonyx, the Jobaria, and the Majungatholus? Get out your pencils and prepare to meet some of the more unusual sauruses ever! For example, the gigantic Acrocanthosaurus had extra-tall spines on its back while the flying Iberomesornis was only the size of a sparrow. All the dinosaurs shown here were discovered after 1990-or they are ones for which paleontologists have recently found good new skeletons. By connecting the dots and forming the pictures, you can learn about these amazing animals. (Color them in when you're done.) And, don't forget to look on the labeled map to find out where they lived, and the timeline to see when!
