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.
Buffetaut and colleagues suggested that, in order to fly, the skull weight of Hatzegopteryx must have been reduced in some way. The necessary weight reduction may have been accomplished by the internal structure of the skull bones, which were full of small pits and hollows (alveoli) up to 10 mm (0.39 in) long, separated by a matrix of thin bony ...
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).

Although it is widely thought that Quetzalcoatlus reached the size limit of a flying animal, the same was once said of Pteranodon. The heaviest living flying animals are the kori bustard and the great bustard with males reaching 21 kilograms (46 lb).
The Quetzalcoatlus' huge wings hamper its escape in the forest as the T. rex bites its foot. The Quetzalcoatlus pecks at the T. rex's eye and flies away. One hatchling survives the attack. Two T. Rexes hear a mating fight between two Triceratops and attack the loser. Working together, they bring down the Triceratops and eat it.
Azhdarchoidea (/æʒdɑːrˈkɔɪdɪːə/, meaning "azhdarchid-like forms") is a group of pterosaurs within the suborder Pterodactyloidea.Pterosaurs belonging to this group lived throughout the Early and Late Cretaceous periods, with one tentative member, Tendaguripterus, that lived in the Late Jurassic period.
All 10 people killed when a regional airline flight crashed off the coast of western Alaska have been recovered and identified, authorities said Saturday. “All ten individuals aboard the Bering ...
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.
