Dactyls. Flying Dragons. Pterodactylus. Whatever you call them, they are simply wonderful! Renowned paleontologist Dr. Robert T. Bakker explains how scientists observe fossils and living animals to determine how dactyls flew, walked, climbed, fed, and thought. Also included for the first time ever is his latest, still-unnamed discovery–an unusual dactyl with sharp-edged, backwards curved teeth, nicknamed "Snaggle Tooth."
