 Soon afterwards, Hermann von Meyer classified the same specimen as the new genus and species "Gnathosaurus subulatus", a name which came to be universally used shortly thereafter.In the 1860s, scientists such as Albert Oppel compared the "G. subulatus" jaw fragment to contemporary pterosaurs such as "Pterodactylus" and "Ctenochasma", and concluded that it was also probably a "flying reptile" rather than a crocodilian.A more complete skull of an adult pterosaur was found in 1951 and classified as "Gnathosaurus subulatus".
