Quetzalcoatlus was perhaps one of the last and largest Pterosaurs ever to have lived, with an 11-13 metre wingspan, yet a hollow-boned lightweight body of less than 120 kilograms. It existed in the Late Cretaceous of North America. It was named after the Meso-American Mayan and Incan feathered serpent god Quetzalcoatl. Once the largest known Pterosaur, Hatzegopteryx has now apparently taken this title.
