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.

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).

About 76 million years ago, a juvenile of one of the largest flying creatures in Earth's history, called Cryodrakon boreas, walked along a riverbank on a lush coastal plain and lowered its ...
Scene from When Dinosaurs Ruled the Earth depicting an outsized Rhamphorhynchus. The vague generic term "pterodactyl" is often used for these creatures. The animals depicted in fiction and pop culture frequently represent either the Pteranodon or (non-pterodactyloid) Rhamphorhynchus, or a fictionalized hybrid of the two. [210]
Alexander Kellner, for example, named several additional species for specimens previously classified as Pteranodon, and placed P. sternbergi in a distinct genus, Geosternbergia. Kellner re-defined Pteranodontidae as the most recent common ancestor of Pteranodon longiceps , Geosternbergia sternbergi and Dawndraco kanzai , and all of its descendants.
