Peteinosaurus (Peh-TEIN-o-sore) was a genus of flying reptiles belonging to the Pterosauria. They existed in the late Triassic period (228 to 215 million years ago).

Beautifully preserved fossils of the flying reptile, Peteinosaurus was discovered near Cene, Italy in rocks of Triassic age. Peteinosaurus had a very light-boned skeleton.

It had even-sized, sharp, cone-like teeth. It is most likely that it ate insects which it caught on the wing.

Its wings consisted of skin stretched between an elongated finger on its hand, and it's foot. The wings were attached to its body and thigh.

It had a long straight tail (20 cm) of vertebrae strengthened with bone-like fibres, which it used for precise manoeuvring. Peteinosaurus is one of the earliest vertebrates to show evidence of flying rather than gliding.

Peteinosaurus was featured in the first episode of the popular British documentary series Walking With Dinosaurs, though it doesn't have much screentime.
