"Charles Darwin had shaken the very foundations of Victorian society with his theory of evolution by natural selection, and scientists across the civilized world were locked in a great battle over Darwin's idea. While the debate raged in Europe, the hunt for hard evidence increasingly focused on the American West, with its grand mesas, buttes, and badlands. ". "Could the answer to the history of life and the proof of evolution be found in fossils? That was the question that two young American paleontologists - Edward Drinker Cope and Othniel Charles Marsh - set out to answer. But what began as a friendly contest quickly turned into bitter rivalry that would spill over into American science and politics and rage relentlessly for nearly three decades. ". "Among the most remarkable fossil discoveries of Cope and Marsh are a bevy of dinosaurs, including some of the best known beasts - the Triceratops, the Stegosaurus, the Camarasaurus, and the Brontosaurus. Even today, Marsh holds the record for dinosaur discoveries. "--BOOK JACKET.
