Quetzalcoatlus

A legendary creature possibly referred to as the serpent god in Aztec mythology, Quetzalcoatlus was as tall as a giraffe while roaming on its feet. Once it took to the sky, its wingspan was from 3040 feet (1012 m) thats as long as most buildings in Paris are high. A lizardlike creature, Quetzalcoatlus may also have been what our ancestors referred to as dragons.
