Quetzalcoatlus (kɛtsəlkoʊˈætləs) was a pterodactyloid pterosaur known from the Late Cretaceous of North America (Maastrichtian stage, about 68–66 million years ago), and one of the largest known flying animals of all time. It was a member of the Azhdarchidae, a family of advanced toothless pterosaurs with unusually long, stiffened necks. Its name comes from the Mesoamerican feathered serpent god Quetzalcoatl.
Quetzalcoatlus only appeared in the Dinosaur video game. Because it flies, Aladar can't defeat it (let alone reach it), so Zini and Flia must do it for him.
The Quetzalcoatlus in the game looks nothing like the real animal, which had a long neck and a large head.
