A pterosaur is a winged dinosaur. They are the first of the vertebrate dino-critters that achieved powered flight.

Wikipedia has additional information, and a link is provided.

EDIT: NO pterosaurs are NOT dinosaurs.

There are dinosaurs alive to day with wings. We call them Birds.

Wings evovled in the group of theropod dinosaurs called Maniraptora.

The big difference between pterosaurs and flying dinosaurs (birds) is that the wing in pterosaurs is made of a fleshy membrane whereas the wings in flying dinosaurs are made of feathers.
