Geared towards a broad variety of students, Dinosaurs: The Textbook, sixth edition, is a concise and lucid presentation of the biological and geological concepts of dinosaur science. It clarifies the evolution, phylogeny, and classification of the various species while modeling the best approach for navigating new and existing research. Revised to reflect recent fossil discoveries and the current consensus on dinosaur science, this text moves through the major taxonomic groups-including theropods, sauropodomorphs, ornithopods, ceratopsians, pachycephalosaurs, stegosaurs, and ankylosaurs-and concludes with updated chapters on the behavior and extinction of the dinosaurs, their biological relationship to birds, and their representation (or misrepresentation) in art, literature, film, and other forms of popular culture. The sixth edition represents a major revision of the leading text for an introductory course on dinosaurs, including comprehensive updates based on the latest scientific discoveries, research, and literature. With an extensive art program revised by leading paleoartists that features cutting-edge illustrations, it is a complete reader-friendly pedagogical package with extensive end-of-chapter summary tools, review questions, a detailed glossary, a dinosaur dictionary, and a comprehensive index.
