''Quetzalcoatlus'', named after the Aztec feathered serpent god Quetzalcoatl , was a pterodactyloid Pterosaur known from the Late Cretaceous of North America ( Campanian - Maastrichtian stages, 84-65 ma), and one of the largest known flying animals of all time. It was a member of the Azhdarchidae , a group of advanced toothless pterosaurs. Skeletal remains of two species have been recovered from the Big Bend Region of Texas ; the larger of the two (''Q. northropi'') had an estimated Wingspan of up to 12m (39 feet). There is still considerable debate as to the upper limit of ''Quetzalcoatlus'' wingspans. The largest remains, on display at the Science Museum Of Minnesota , are somewhat scrappy, and may indicate an individual with a wingspan as large as 18m (59 feet). Such a wingspan, however, may violate fundamental structural limits imposed on biological fliers; some scientists favor a wingspan closer to 9m (30 feet) in light of these arguments. The largest '' Pteranodon '' individuals with 6 metre (20 foot) wingspans were once thought to represent the size limit in biological fliers before the discovery of ''Quetzacoatlus'', so the matter is clearly still open. The first ''Quetzalcoatlus'' fossil was found by Douglas A. Lawson. During the Cretaceous , Texas's climate was similar to modern tropical coastal Wetland s and lagoons, extending along the Cretaceous Seaway that filled the center of North America. Bones of related animals are also known from Dinosaur Provincial Park , Alberta , Canada . There are a number of different ideas about the lifestyle of ''Quetzalcoatlus''. With its long neck Vertebrae and long toothless jaws it might have fed on fish like a Heron , or perhaps it scavenged like the Marabou Stork . Presumably ''Quetzalcoatlus'' could take off under its own power, but once aloft it may have spent much of its time soaring. On the ground, ''Quetzalcoatlus'' probably walked on all fours. Along with the Dinosaur s, ''Quetzalcoatlus'' became extinct at the end of the Cretaceous period. TRIVIA
