Dinosaurs of the Air

by Gregory S. Paul

"Dinosaurs of the Air: The Evolution and Loss of Flight in Dinosaurs and Birds presents the most recent work of renowned evolutionary scientist and dinosaur illustrator Gregory Paul. Dinosaurs of the Air synthesizes the growing body of evidence which suggests that modern-day birds have evolved from theropod dinosaurs of prehistoric times. Paul argues provocatively for the idea that the ancestor-descendant relationship between the dinosaurs and birds can on occasion be reversed, and that many dinosaurs were secondarily flightless descendants of creatures we would regard as birds."--BOOK JACKET.
