As you did a bit of research, surely you read

DALLA VECCHIA F.M., 1998 - New observations on the osteology and taxonomic
status of Preondactylus buffarinii WILD, 1984 (Reptilia, Pterosauria).
Boll. Soc. Paleont. It., 36(3, 1997): 355- 366, Modena.

DALLA VECCHIA F.M., 2003 - New morphological observations on Triassic
pterosaurs. In: BUFFETAUT E. & MAZIN J.-M. (eds), Evolution and
Palaeobiology of Pterosaurs, Geological Society, London, Special
Publications, 217: 23-44, London.

DALLA VECCHIA F.M., 2004 - A review of the Triassic pterosaur record. Riv.
Mus. Civ. Sci. Nat. ?E. Caffi?, 22: 13-29, Bergamo.


Thus you should have realized that the supposed large specimen of
Preondactylus, actually just three wing phalanges, cannot be unambiguously
attributed to that genus, whatever the weight invented for it by some
brilliant guys of the web.
I apologize for the shameless self-promotion.
