This book is from the set of books, Dinosaur Wars. In this book, it compares the two dinosaurs-deinonychus and styracosaurus. The book welcomes the reader to dinosaur wars! The book then goes into detail about each dinosaur comparing their size, speed and agility, defenses, weapons and attack style. Even though these two dinos never battled each other, it discusses what may have happened had they battled. I really like the layout of this book. On the left facing page there is the information about the deinonychus, along with a picture and then on the right is the information about the styracosauus (and a picture). On each set of facing pages there is also a fierce fact and a glossary word. At the end of the book, there is a fictionalized story of the two dinos meeting and battling. I think that kids will really like how the book nicely compares two different types of dinosaurs and the story with the “dinosaur war” at the end. Great set of nonfiction dinosaur books!
