Pterosaurs are extinct flying reptiles. They lived worldwide in all kinds of environments and ranged from around 50 cm to 13 m in wingspan. They existed from about 225 to 65 million years ago and thus ran alongside the dinosaurs pretty much toe to toe for their entire existence, dying out in the great extinction at the end of the Cretaceous period. Although they first appeared in the Triassic period, their origins might extend beyond that by some margin, but fossils of this time are rare, so it is hard to say.
