Preondactylus is a genus of long-tailed pterosaurs from the Late Triassic (Carnian-Norian[1] or late Norian,[2] about 217-214 million years ago)[3] that inhabited what is now Italy. It contains a single known species, Preondactylus buffarinii, which was discovered by Nando Buffarini in 1982 at the Forni Dolostone near Udine in the Preone valley of the Italian Alps.
