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."
