Pretend that you are living during the Cretaceous period. Then look up at the sky. That fierce winged creature swooping down on you is a pterodactyl, a flying reptile.
The word pterodactyl, pronounced "tear-uh-DACK-til," refers to a now-extinct group of winged reptiles known as pterosaurs. The word comes from the Latin Pterodactylus, the creatures' genus name, which originated in the Greek pteron, meaning “wing,” and daktulos, meaning “finger.” Although technically not a dinosaur, this flying reptile thrived during the same time period is as often seen among dinosaurs in movies.
