 He found several of the bone identifications and interpretations to be mistaken, such as the skull bone (interpreted here as just a bone fragment of unknown origin), elongate tail vertebra (the presumed elongated extensions were ribs), humerus (unknown), and the orientation of the bone described as a scapulacoracoid (the scapula and coracoid parts had been confused).He could not locate other bones seen as impressions, and found no evidence to suggest that the identifiable bones came from a pterosaur.In fact, he found the general quality of the bone texture to differ from that of pterosaur bones.
