A second, disarticulated specimen, MFSN-1891, was found at the same locale in 1984 about 150–200 meters (490–650 ft) deeper into the strata than the original find. The second specimen appears to have been preserved in the gastric pellet of a predatory fish, which had consumed the pterosaur and vomited up the indigestible pieces that would later fossilize.[1] More detailed knowledge of the variability of Triassic pterosaurs has made the identification of this specimen as Preondactylus uncertain, and it may even be that the remains are not those of a pterosaur at all.
