Pterosaurs (TEH-row-sore, "winged lizards," often incorrectly referred to as "pterodactyls" (TEH-row-DAK-tils) were flying reptiles of the clade Pterosauria. They existed from the late Triassic to the end of the Cretaceous period (228 to 65 million years ago). The earlier species had long, fully-toothed jaws and long tails, while later forms had a stump for a tail, no teeth and a jaw more like a beak than the elongated jaw of the earlier species. Pterosaurs are classified as archosaurs, along with crocodiles and dinosaurs (and the dinosaurs' descendants, the birds).
