Pterosaurs are a group of “reptiles” that have evolved powered flight. To be more precise, they are classified in a group called the Ornithodira or “bird necks”, which in turn is a subgroup of the Archosaurs, or “ruling reptiles,” that includes crocodiles, dinosaurs including birds, and “thecodonts.” “Pterosaur” comes from two Greek words that together mean “winged lizard.” The word “pterodactyl” is also often used. It means “wing finger” and it is an apt description; the wing of the pterosaur is supported mainly by an elongated fourth digit along the forward edge.
