The story of the word

Cuvier studied a fossil from the Bavarian limestone in 1809 and called it ptéro-dactyle for its hugely elongated fourth finger, which carried the wing membrane. The animal was never a dinosaur. Helicopter, apterous and pterosaur all carry the same πτερόν, and δάκτυλος also names the dactyl of Greek metre, a long syllable followed by two short ones, like the bones of a finger.
