Everyone has heard of the T. rex, but it wasn't the only scary dinosaur out there! Others were also bigger, more agile, faster, and perhaps deadlier. This volume of prehistoric dinosaurs introduces some lesser-known species to even the most dinosaur-loving reader, making it an essential volume for elementary libraries and classrooms. From size and strength to body features and behavior, the details of each dinosaur are included alongside accurate illustrations of each. A timeline at the end of the book aids readers' understanding of prehistory and dinosaurs alike.
