This is the first supplement to the highly acclaimed Dinosaurs: The Encyclopedia that was named an ALA Outstanding Reference Book. The new work, which maintains the arrangement of the primary volume and is up to date late into 1998, includes well over a dozen new dinosaurian genera and even more new species and new life restorations. Section I provides introductory text on subtopics such as "The Mesozoic Era," "Ectothermy Versus Endothermy" and "Dinosaur Extinctions." Section II continues the workable ordering of dinosaurian systematics. Section III continues the alphabetical compilation of new dinosaurian genera. Section IV continues the detailing of doubtful genera that have appeared in the paleontological literature. Supplemental volumes do not repeat information from earlier volumes, but build upon them: view all volumes on the series page.
