The Caudipteryx was a dinosaur available in Zoo Tycoon: Dinosaur Digs. It is somewhat birdlike in appearance and lives in a tropical rainforest. They apparently enjoy a lot of freshwater, and in the game were stated to come from the Jurassic period (although they were actually found in Early Cretaceous Asia.) They are available with Camptosaurus when you first get new items. Caudipteryx also appears in several fan-made packs for Zoo Tycoon 2, usually made from the Protarchaeopteryx or Secretary Bird.
