Dinosaurs: A Concise Natural History, Edition 4

David E. Fastovsky is Professor and Chair of the Department of Geosciences at the University of Rhode Island. His interest in dinosaurs began in his early years when he read about a paleontologist's adventures in the Gobi Desert early in the twentieth century. Dinosaurs won out years later when he had the tough decision of choosing between a career in music or paleontology. He has since carried out fieldwork all over the world. He is known as a dynamic teacher as well as a respected researcher on the environments in which dinosaurs roamed, as well as their extinction.

David B. Weishampel is Professor at the Center for Functional Anatomy and Evolution at Johns Hopkins University School of Medicine. His research focuses on dinosaur evolution and how dinosaurs function, and he is particularly interested in herbivorous dinosaurs and the dinosaur record of Europe. He is senior editor of The Dinosauria and has contributed to a number of popular publications, including acting as consultant to Michael Crichton in the writing of The Lost World, the inspiration for Steven Spielberg's film Jurassic Park. He was recently honoured in an International Symposium on duck-billled dinosaurs, dedicated to him and his research.

John Sibbick has been creating illustrations of extinct life forms and their environments for over thirty years, producing numerous books on dinosaurs, as well as pterosaurs, and general books on prehistoric life. His work has appeared in scientific magazines, television documentaries and museums, and featured on a set of stamps depicting dinosaurs and other prehistoric reptiles for the United Kingdom's Royal Mail.
