Etymology: Georges Cuvier, the French naturalist, coined the term "ptérodactyle" in French, building it from two ancient Greek words: "pterón", meaning "wing", and "dáktulos", meaning "finger". The name describes the animal's most distinctive feature: its wing was supported by an enormously elongated fourth finger, while the other digits remained small and clawed. Cuvier was describing the creatures from their fossils, so the name records an anatomical discovery rather than any living observation. The Greek roots were chosen to make the anatomy clear at a glance. Pterosaurs were not dinosaurs, though the name is often used loosely, and the word has since been carried into English along with the scientific classification that Cuvier's work helped establish.
