Toothless 'Dragons' Roamed Our Skies

A family of animals ruled the skies some 90 million years ago, but they weren't dinosaurs, and they weren't birds, and they didn't even have teeth. The winged reptiles of the late Cretaceous period belong to a family of pterosaurs called Azhdarchidae, and they appear to have had remarkable dominance...
