Quetzalcoatlus was a pterodactyloid pterosaur known from the Late Cretaceous of North America and was the largest known flying animal 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. It had a wingspan of between 10–12.3 meters (33–40 ft) and weighed 200 kilograms (440 lbs). The diet of Quetzalcoatlusis still debated since it had a toothless beak. It may have ate carrion, fish and/or dinosaur hatchings.
We only see it in all scene in the late Cretaceous segment. It is flying over when it sees a dead Triceratops. It starts to feast on the rotten remains when a young male Tyrannosaurus rex charges at it, causing it to fly away. Luckily for the pterosaur, it escapes and we follow the pterosaur, and at the end, it lands on the tree like a vulture.
