New observations on the osteology and taxonomic status of Preondactylus buffarinii WILD, 1984 (Reptilia, Pterosauria).
New observations about the osteology and the systematic position of Preondactylus buffarinii Wild 1984b, are based on a reexamination of the holotype (1770MFSN). The carpus and metacarpus of this specimen are described in detail after further preparation. New measurements for the wing metacarpal, first wing phalanx and tibia are presented, allowing new postcranial bone length ratios to be calculated. Similarities of P. buffarinii to Peteinosaurus zambellii are emphasized; its condition of most primitive pterosaur is open to discussion and its diagnosis is emended.
