The IKS Pterodactyl-of-Prey was a ship under the service of the Lyran Starfleet in the 25th century. Built out of an U'lanna astro-miner in the Idlewild system, it was the flagship of the U'lanna Rebel Alliance before the Alliance was disbanded after the destruction of the astro-miner, and later outfitted with deflector shields despite its absence of crew, carrying Klingon zombies. (Star Trek: The Stoneship Files: "A Knight without Armor") She participated in the raid on Du'Qot in order to turn the planet's population into zombies.
