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.
Hatzegopteryx (A-B), Arambourgiania (C) and Quetzalcoatlus sp. (D-E) The largest known pterosaur was Quetzalcoatlus northropi, at 127 kg (280 lb) and with a wingspan of 10–12 m (33–39 ft). [378] Another close contender is Hatzegopteryx, also with a wingspan of 12 m (39 ft) or more. [378] This estimate is based on a skull 3 m (9.8 ft) long ...
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).

Paleontologist Mary Anning and her older brother, Joseph, discovered the first known ichthyosaur fossils in 1811 and 1812, decades before the word dinosaur was even part of our lexicon.
Well-known examples of pterodactyloids include Pterodactylus, Pteranodon, and Quetzalcoatlus. In 2014, fossils from the Shishugou Formation of China were classified as the most basal pterodactyloid yet found, Kryptodrakon. At a minimum age of about 161 my, it is about 5 million years older than the oldest previously known confirmed specimens. [4]
Cast of an assigned wrist bone. The first pterosaur remains from Romania were identified by Franz Nopcsa in 1899, and the first remains of Hatzegopteryx were found during a student dig in the late 1970s from the upper part of the Middle Densuş Ciula Formation of Vălioara, northwestern Hațeg Basin, Transylvania, western Romania, which has been dated to the late Maastrichtian stage of the ...
Lawson was at Big Bend searching for the bones of titanosaur sauropods, such as Alamosaurus, when the pterosaur bones, which he later named Quetzalcoatlus, were discovered. When the discovery of the fossils was reported in 1975, Quetzalcoatlus was the largest flying creature known to have lived. [ 3 ]
