The Pterodactyl is a flying reptile having wings of skin with a span of up to 20 feet.
Pterodactyl are, on the whole, rather rare. Sometimes these beasts are targets for archers, although they can be beneficial to humans.
In 966 GUE a humble peasant found a pterodactyl that could be summoned by a whistle, and would agree to fly the peasant anywhere on three, but only three occasions.
This beast, along with presumably its entire race, was intelligent and could communicate telepathically. However, it was incredibly afraid of wild monsters.
