Quetzalcoatlus

Genus of azhdarchid pterosaurs from the Late Cretaceous

Quetzalcoatlus is a genus of azhdarchid pterosaur known from the Late Cretaceous Maastrichtian age of North America. Its name comes from the Aztec feathered serpent god Quetzalcoatl. The type species is Q. northropi, named by Douglas Lawson in 1975 after the tailless fixed-wing aircraft designer Jack Northrop. The genus also includes the smaller species Q. lawsoni, which was known for many years as an unnamed species, before being named by Brian Andres and Wann Langston Jr. (posthumously) in 2021. Q. northropi has gained fame as a candidate for the largest flying animal ever discovered.
