Author Description

Dinosaurs ruled the Earth for millions of years and they still rule the record books! That's because they had to be extreme to survive in those prehistoric days. So meet the creatures that have never been equaled: Amphicoelias, who outsized all the other dinos; Struthiominus, the fastest runner; Spinosaurus, the biggest two-legged predator that ever lived; and many more. In addition to the fun facts and figures, there's a timeline, a box that compares each dinosaur's size to a human's, and information on who named the dinosaur."
