New Perspectives on Horned Dinosaurs The Royal Tyrrell Museum Ceratopsian Symposium

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. This volume 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.
