Found in North America, the Diplodocus was an herbivore, but it could do some serious damage. With a whip-like tail that could swing at 800 miles per hour, the Diplodocus kept itself safe from predators while it dined on leaves high in the tree tops. Young readers will discover how the Diplodocus is believed to have lived millions of years ago. With amazing illustrations paired closely with important facts, this book invites readers to dive right into how scientists believe Diplodocus lived and thrived.
