Here is the fifth supplement to Dinosaurs: The Encyclopedia, a 1998 American Library Association Outstanding Reference Book. Since the publication of the acclaimed first volume, a virtual explosion in the number of exciting discoveries in dinosaur paleontology has made supplemental volumes necessary and indispensable. Among the many dramatic events discussed in the fifth supplement are the discovery of what may be the largest Jurassic theropod specimen yet collected; the uncovering of evidence of a dinosaur possessing opposable fingers; and Robert M. Sullivan's reassessment of Pachycepholasauria. Like the previous supplements, this volume includes lengthy sections on dinosaurian schematics and genera and updates the encyclopedia's list of excluded genera.

Supplemental volumes do not repeat information from earlier volumes, but build upon them: view all volumes on the series page.
