About Quetzalcoatlus
Quetzalcoatlus 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. The generic name refers to the Aztec serpent god of the sky, Quetzalcōātl, while the specific name honors Jack Northrop, designer of a tailless fixed-wing aircraft. The remains of a second species were found between 1972 and 1974, also by Lawson, around 40 km (25 mi) from the Q. northropi locality. In 2021, these remains were assigned to the name Quetzalcoatlus lawsoni by Brian Andres and (posthumously) Wann Langston Jr., as part of a series of publications on the genus.
