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.

Northrop because of its similarity to Northrop's flying ...
