DINOSAURS: What We Know, How We Know

Mark's art of dinosaurs, including Tyrannosaurus rex, will appear as the jacket cover and selected interior illustrations for a new book, DINOSAURS: What We Know, How We Know by paleobiologist Mary H. Schweitzer and her coauthors. This book will explore the newest discoveries of dinosaurs based on Dr. Schweitzer's molecular biology studies of the ancient animals' soft tissues and bones.
