A large, primitive flying reptile that lives in the Un'Goro Crater. Pterrordax move around in quick nervous stretches of flight, followed by slower gliding.
Pterrordax have a scream attack that cause fear in those hearing it.
They are also known as Pteradon. A Pteradon Skeleton hangs in The Library in Ironforge with the note: This intact pteradon skeleton was recovered from the remote Un'Goro Crater. Based on the skeletal structure, it is clear that this specific genus has not yet been encountered. This skeleton could have been preserved for any number of centuries beneath the region's rich soil.
