A comprehensive study of the Late Cretaceous, duck-billed dinosaur, featuring insights on its origins, anatomy, and more.

Hadrosaurs—also known as duck-billed dinosaurs—are abundant in the fossil record. With their unique complex jaws and teeth perfectly suited to shred and chew plants, they flourished on Earth in remarkable diversity during the Late Cretaceous. So ubiquitous are their remains that we have learned more about dinosaurian paleobiology and paleoecology from hadrosaurs than we have from any other group. In recent years, hadrosaurs have been in the spotlight. Researchers around the world have been studying new specimens and new taxa seeking to expand and clarify our knowledge of these marvelous beasts. This volume presents the results of an international symposium on hadrosaurs, sponsored by the Royal Tyrrell Museum and the Royal Ontario Museum, where scientists and students gathered to share their research and their passion for duck-billed dinosaurs. A uniquely comprehensive treatment of hadrosaurs, the book encompasses not only the well-known hadrosaurids proper, but also Hadrosaouroidea, allowing the former group to be evaluated in a broader perspective. The 36 chapters are divided into six sections—an overview, new insights into hadrosaur origins, hadrosaurid anatomy and variation, biogeography and biostratigraphy, function and growth, and preservation, tracks, and traces—followed by an afterword by Jack Horner.

“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, co-author of 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
