==Discovery== thumb|left|Fossil wing bones When Buffarini first discovered Preondactylus, the thin slab of bituminous, dolomitic limestone containing the fossil was accidentally broken into pieces while being extracted. After reassembly the rock was cleaned with water by him and his wife and the marl and in it the bone was washed away and lost. All that was left was a negative imprint on the stone, of which a silicone rubber cast was made to allow for subsequent study of the otherwise lost remains. Most of the skeleton is known, but the posterior portions of the skull have not been preserved. This first specimen is the holotype: MFSN-1770. thumb|left|Cast of a Preondactylus buffarinii
