The story of the word

Wing lizard, though they were not lizards and sit closer to dinosaurs and birds than to anything now alive. Each wing was a single membrane stretched from an enormously long fourth finger back to the ankle, quite unlike a bat's spread of four. Kaup grouped them as Pterosauria in 1834, and the largest of them, Quetzalcoatlus, stood about as tall as a giraffe.
