Quetzalcoatlus

Quetzalcoatlus was a Pterosaur with a wingspan of 12 m (40 feet) and a weight of only about 50 kg (110 pounds), that lived during the late Cretaceous period.

Quetzalcoatlus fosils have been found in Texas. During the Cretaceous, Texas' climate was similar to a modern wetland. Paleontologists theorize that Quetzalcoatlus may have lived like a modern crane or stork, since Quetzalcoatlus' hip is adapted for bipedal locomotion.

Its name comes from Quetzalcoatl, the Aztec Feathered-Serpent deity.
