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. New format of Dinosaur Record Breakers for a younger audience.
