"[T]he book constitutes a worthy addition to the vast hadrosaurid literature, and will mainly appeal to those that are seriously invested in furthering their knowledge on these animals. The editors and all authors involved are to be commended for their efforts in producing such an scholarly volume containing a wealth of valuable new information on one of the most remarkable evolutionary radiations of Mesozoic terrestrial vertebrates."—Ameghiniana"Part of the excellent 'Life of the Past' series, [this book] contains much recent information and a thorough analysis of hadrosaur anatomy, particularly as it contributed to hadrosaurs' herbivorous lifestyle. . . . The 36 chapters are technical, requiring a thorough knowledge of vertebrate anatomy and a general familiarity with dinosaur biology, and prolifically illustrated with clear diagrams and black-and-white photographs. Time devoted to this book will convince any dinosaur student that hadrosaurs were far more than food for tyrannosaurs. . . . Highly recommended."—Choice"Well designed, handsome and fantastically well edited (credit there to Patricia Ralrick), congratulations are deserved to the editors for pulling together a vast amount of content, and doing it well. The book contains a huge quantity of information on these dinosaurs."—Darren Naish, Tetrapod Zoology, Scientific American"Hadrosaurs have not had the wide publicity of their flesh-eating cousins, the theropods, but this remarkable dinosaur group offers unique opportunities to explore aspects of palaeobiology such as growth and sexual dimorphism. In a comprehensive collection of papers, all the hadrosaur experts of the world present their latest work, exploring topics as diverse as taxonomy and stratigraphy, locomotion and skin colour."—Michael Benton, University of Bristol
