Some of the biggest dinosaurs to walk the earth weren't so scary at all. They'd rather eat a leafy salad than another animal. This book introduces readers to some of the most amazing plant-eating dinosaurs to ever live. Readers will learn about dinosaurs that had thick spines, spiky hands, and horns on their heads, which were probably adaptations for survival. They'll discover dinosaurs that believed in safety in numbers and those that were built like living tanks. Readers will enjoy artistic renderings of dinosaurs, fast facts, and diagrams. This book is an inside glimpse at the gentle giants of long ago!
