The Illustrated Dinosaur Encyclopedia?is an unmatched reference work distinguished by its erudition and beauty—an illustrated who's who of prehistoric life and a source book of more than 500 million years of evolution on Earth. With entries for more than 600 species, each arranged in its evolutionary sequence, this book presents a panorama of enormous diversity, from predatory dinosaurs to primitive amphibians, from giant armored fish to woolly mammoths, saber-tooth tigers, and dire wolves.
