This reference work is the sixth supplement to Dinosaurs: The Encyclopedia (a 1998 American Library Association Outstanding Reference Book) and follows the intent and format of the encyclopedia and previous supplements. Among the many dramatic events discussed and updated are the discoveries of a basal titanosaur that may be the largest dinosaur yet found in China; the first large-bodied theropod from Pakistan; the largest Jurassic theropod tooth yet documented; and the first preserved integument and bonebed pertaining to the horned dinosaur Triceratops. This volume also includes lengthy sections on dinosaurian schematics and genera and updates the encyclopedia's list of excluded genera. One appendix provides a main-entry catalog of dinosaurian genera. Supplements do not repeat information from earlier volumes, but build upon them.
