4Dinosaurs had some incredible adaptations--such as plates, horns, and frills. These were necessary to survive and thrive in an eat-or-be-eaten world. This useful guide to more than 40 dinosaurs, including Amargasaurus, Ankylosaurus, and Kentrosaurus, clues in readers to the unique bodies of these reptiles and how paleontologists think they functioned. Each dinosaur is paired with a table of information, which includes when it lived, where it lived, what it ate, and how big it was. An image comparing the creature to a person helps readers fathom their often immense dimensions. This beautifully designed volume is a high-interest resource for any life science studies collection.
