Quetzalcoatlus (/ k ɛ t s əl k oʊ ˈ æ t l ə s /) is a genus of azhdarchid pterosaur that lived during the Maastrichtian age of the Late Cretaceous in North America. The type specimen, recovered in 1971 from the Javelina Formation of Texas, United States, consists of several wing fragments and was described as Quetzalcoatlus northropi in 1975 by Douglas Lawson.
However, the pterosaurs had to share the skies with some remarkable flying dinosaurs like Microraptor. From these feathered flyers evolved the birds, who survived the K-Pg mass extinction. Some, like the swans, could gracefully fly at 30 mph as David Attenborough shows when he tracks their progress on a boat.
Azhdarchidae (from the Persian word azhdar, اژدر, a dragon-like creature in Persian mythology) is a family of pterosaurs known primarily from the Late Cretaceous Period, though an isolated vertebra apparently from an azhdarchid is known from the Early Cretaceous as well (late Berriasian age, about 140 million years ago).

Cryodrakon rivaled Quetzalcoatlus, which also inhabited North America at the time, as the largest of the pterosaurs, which were cousins of the dinosaurs. Both had large heads with large toothless ...
Lawson began his synecological research during his master's degree studying the paleoecology of the Tornillo Formation in Big Bend National Park, Texas.During his study of this Late Cretaceous intermontane basin community, he discovered the fossil remains of the giant pterosaur, Quetzalcoatlus Northropi, which he named in honor of John K. Northrop because of its similarity to Northrop's flying ...

The name Quetzalcoatl comes from Nahuatl and means "Precious serpent" or "Quetzal-feathered Serpent". [15] In the 17th century, Ixtlilxóchitl, a descendant of Aztec royalty and historian of the Nahua people, wrote, "Quetzalcoatl, in its literal sense, means 'serpent of precious feathers' but in the allegorical sense, 'wisest of men'."
