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: Edmontonia, the spikiest dinosaur; Laellynasaura, with the longest tail ever; Therizinosaurus, a super slasher with killer claws; Fruitadens, the smallest plant eater; and many more.
In addition to the fun facts and figures, there's amazing CGI artwork, a timeline, a box that compares each dinosaur's size to a human's, and information on who named the dinosaur.
