Coelurosauravus.

Coelurosauravus (see-low-row-SORE-uh-vus (or) see-lore-oh-SORE-ay-vus) was a genus of late Permian reptile with "wings" that were either for gliding or display. It was very similar to the Triassic kuehneosaurids, but unlike the kuehneosaurids, it had a crest, like the crest of the dinosaur Protoceratops.

Coelurosauravus's wings resembled those of a moth, but they were made of stretched out bones covered with skin.

Coelurosauravus had sharp claws used for climbing tree bark. It was about 16 inches long.

Coelurosauravus probably ate flying insects like palaeodictyopterans. It was the first reptile to "fly." It could only glide, because it didn't have muscles in its wings which would allow it to actually flap them.
