Preondactylus is a genus of long-tailed pterosaurs from the Late Triassic about 228 million years ago that inhabited what is now Italy. It contains a single known species, Preondactylus buffarinii.
Preondactylus had single cusp teeth, meaning they had one point on each tooth. Its diet either consisted of fish, insects or both, but there is still debate going on as the tooth structure could indicate either diet (or both). It had short wings, whose total span was only 45 cm (18 in), and relatively long legs. The short wings were a "primitive" feature for pterosaurs, but Preondactylus was a fully developed flier.
