Ceratopsids, or horned dinosaurs, are a group of large-bodied, quadruped herbivores, which lived roughly 65-70 million years ago. Part of a larger group of dinosaurs that includes stegosaurs, ankylosaurs, ornithopods, and pachycephalosaurs, the better-known members of the ceratopsids include centrosaurs, chasmosaurs, and triceratops. Easily distinguished by the horns and frills on their skulls, ceratopsids were one of the most successful of all dinosaurs. New Perspectives on Horned Dinosaurs presents a broad range of cutting-edge research on the functional biology and behavior, systematics, paleoecology, and paleogeography of the horned dinosaurs, including descriptions of newly identified species. A CD-ROM includes a census of recovered specimens and a history of ceratopsian discoveries in Canada.

"Triceratops and its kin may hail from the dim and distant past, but this new volume brings them fully into the light of today. An all-star and comprehensive list of authors not only effectively puts horned dinosaurs in the context of their own time and place, but also brings them alive as living, breathing biological organisms. New Perspectives on Horned Dinosaurs is able proof of the vitality of modern dinosaur science, bringing to bear 21st-century ideas and approaches to ask – and answer – questions that once would have been thought to be out of reach."
– Larry Witmer, Ohio University
"New Perspectives on Horned Dinosaurs records a landmark event and makes clear that our understanding of this group is undergoing truly explosive growth. To give just one measure, the number of ceratopsids discussed at this meeting represented a doubling of species compared to a comprehensive review of this clade published just three years earlier. The remarkable abundance of newly discovered forms was augmented by presentation of rigorous studies of stratigraphy, phylogeny, ontogeny, biomechanics, taphonomy, paleogeography, and paleoenvironment. These results, including descriptions of ten new taxa, are captured in this volume, which will be a must-own for dinosaur paleontologists and enthusiasts alike."
– Scott Sampson, University of Utah
"From Archaeoceratops to Zuniiceratops, from Alaska to Mexico, and from sediments to functional morphology, this book covers much of present-day research on ceratopsians. These horned dinosaurs are rendered as living, behaving, and evolving organisms throughout the 36 chapters of this book. I encourage everyone interested in how a myriad of incredible fossils can inform about life of the past to read it."
– David Weishampel , co-editor of The Dinosauria and co-author of Dinosaurs: A Concise Natural History
"This book captures an explosion of new and exciting research on one of the most fascinating groups of dinosaurs. It will be a landmark in the study of ceratopsians."
– David C. Evans, University of Toronto
"New Perspectives on Horned Dinosarus is an essential reference of lasting importance for anyone interested in horned dinosaurs. Indeed, anyone with a serious interest in dinosaurs will want to own a copy of this fine volume."
– PalArch's Journal of Vertebrate Palaeontology, 7(3), 2010
"[T]his [is] one of the most important horned dinosaur monographs since Richard S. Lull's 1933 overview."
– C&RL News, October 2010
"This richly illustrated volume will be valuable to anyone with a serious interest in dinosaurs [...] Highly recommended."
"An examination of the list of contributors reveals a veritable 'who's who' of ceratopsian and dinosaur researchers from around the world, which is indicative of the depth and quality of the work contained in this book."
– Palaeontological Association Newsletter
"The synthesis of contemporary ceratopsian research and North American paleoenvironmental work makes this book a necessary addition to the library of anyone interested in dinosaur biology and evolution."
– The Quarterly Review of Biology
"All in all, New Perspectives on Horned Dinosaurs is arguably the most significant dinosaur book to appear in recent years, and this is against a lot of competition. It demonstrates – just in case there was any doubt – that feathered maniraptorans and tyrannosaurids are not the only sections of the dinosaur tree where exciting research and discoveries are happening."
– Scientific American
"What a book [this] is! It is huge with a massive 624 pages, and the dustcover, with a wnderful Chasmosaurus by Donna Sloan, is stunning [...] The book itself is very well put together."
