One of the dinosaurs introduced in Zoo Tycoon's first expansion pack, Dinosaur Digs, is the Caudipteryx, a small bird-like dinosaur from Asia. In-game, it is listed as hailing from the Jurassic era, and it's even one of the dinosaurs the player is required to adopt in the "Jurassic Zoo" scenario, which hence its title, requires utilizing all of the game's Jurassic era dinosaurs to win. This is an error on Blue Fang's part, as the Caudipteryx actually hailed from the early Cretaceous period.
