The horned dinosaurs, a group of rhinoceros-like creatures that lived 100 to 65 million years ago, included one of the greatest and most popular dinosaurs studied today: Triceratops. In telling us about Triceratops and its relatives, the Ceratopsia, Peter Dodson here re- creates the sense of adventure enjoyed by so many scientists who have studied dinosaurs since their discovery in the mid- nineteenth century. "It is perhaps surprising that no general work has ever been published about [the Ceratopsia], but the deficit is now redressed by Dodson's engaging, witty, and erudite new book. It is a labor of love by an admitted Oceratophile' (his term), an anatomist particularly skilled in biometrics.... The prose is graceful and never overly serious, and the footnoted asides are informative and amusing, so that even chapters on topics as dry as the necessary skeletal anatomy and principles of classification will be palatable to the non-specialist."--Kevin Padian, Science"In his new book, Peter Dodson, a long-time student of ceratopsians, presents a delightful and authoritative survey of the horned dinosaurs.... Dodson writes in an informal, often cheerfully and unabashedly personal manner. This narrative structure nicely conveys the sense of excitement associated with the discovery of and research on dinosaurs and makes the more technical matters accessible to the interested lay reader."--Hans Sues, American Paleontologist
