Even seasoned caretakers can't always identify a young Pterodactyl Dragon on sight. The trademark wings that stretch wide in the dragon's Epic form are near absent when they are hatchlings.
Pterodactyl Dragons are touchy about their former extinct status. As such, they become flustered when a nearby Caretaker mentions the word. They prefer the term "existence-impaired".
Some folks assume that since Pterodactyl Dragons look so similar to Pterodactyl dinosaurs, they can also fly great lengths. The opposite is true; Pterodactyl Dragons don't have the wing strength to keep themselves aloft for extended periods of time.
Epic Pterodactyl Dragons are fiercely protective of any eggs they lay. Having been "existence-impaired" once before, the species works hard to avoid such dire straits in the future. Be sure you and your Epic Pterodactyl Dragon have a relationship of trust built up before you approach its nest.
