The Peterdactyl was a pterodactyl that Peter attempted to ride in "Meg and Quagmire" to save Meg from Quagmire taking her to his cabin, but dies when it hits an electric wire.

The Peterdactyl was part of a line of Peter's Vehicles that Peter attempted to use to get from one place to another, including the infamous Petercopter and the equally infamous Hindenpeter.
