Hans-Dieter Sues, senior research geologist and curator of vertebrate paleontology, Smithsonian National Museum of Natural History, coauthor of Triassic Life on Land: The Great Transition:
Dinosaurs is a concise, well-written, and profusely illustrated introduction to this ever-fascinating subject. It is ideally suited for college-level courses.

John Cisne, professor emeritus of earth and atmospheric sciences, Cornell University:
This book is the best available introduction to dinosaurs for college students, as earlier editions have been.

Sherwood W. Wise Jr., professor emeritus of geological sciences, Florida State University:
I don't think that you can produce a better book than what Lucas has written. It has been well proved over many years, and this thoroughly updated edition meets the demands of the rapidly evolving science.

Lawrence H. Tanner, professor of environmental science systems and director of the Center for the Study of Environmental Change, Le Moyne College:
Lucas brings four decades of experience in vertebrate paleontology to this logical and thorough treatment of dinosaurs. A challenging—and rewarding—text for students.
