‘This book has it all; this new, fourth edition catches up with all the new ideas from the past ten years, and presents the excitement of being a dinosaur scientist, in the field digging up skeletons, but also in the lab, using the latest tools of science to understand how these amazing ancient animals lived.’ Michael Benton, University of Bristol, UK

‘Professors Fastovsky and Weishampel have done it again. They have performed a great service for the paleontological community by keeping their splendid textbook up-to-date. Their text is easily the best available for undergraduate dinosaur courses. The authors write with clarity but also with a fine sense of whimsy. You wish you could sit in their classroom.

The book is profusely and expertly illustrated, highlighting key points in dinosaurian anatomy and the phylogenetic framework in which these characters are relevant. With the deft touch of skilled paleontologists, they communicate not only what we know about dinosaurs but how we know it. They also recognize that science is a human endeavor done by real people whose stories they tell.

This book is highly recommended for students, teachers and interested lay readers as well.’ Peter Dodson, University of Pennsylvania, USA
