Jack Sparrow and Fitzwilliam P. Dalton III encounter them during their adventures with the Timekeeper. Fitzwilliam mentioned that they were thought to be a myth though some people claimed to have found their bones. Though mostly hostile, Jack and Fitzwilliam did briefly befriend one pterodactyl. Jack named it Drag. The flocks assisted them in escaping from a pair of sabertooth tigers. This species is probably Pteranodon, the most famous Pterosaur of all. In reality, Pterosaurs would never meet sabretoothed tigers as Pterosaurs vanished long before the cats appeared.
