Easily distinguished by the horns and frills on their skulls, ceratopsians were one of the most successful of all dinosaurs. This volume presents a broad range of cutting-edge research on the functional biology, behavior, systematics, paleoecology, and paleogeography of the horned dinosaurs, and includes descriptions of newly identified species.

Michael J. Ryan is Vice-Chair Curator and Head of Vertebrate Paleontology at the Cleveland Museum of Natural History.

Brenda J. Chinnery-Allgeier is Lecturer in the School of Biological Sciences at The University of Texas at Austin.

David A. Eberth is a senior research scientist at the Royal Tyrrell Museum in Drumheller, Alberta, Canada.
