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). [375] Another close contender is Hatzegopteryx, also with a wingspan of 12 m (39 ft) or more. [375] 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).

Unwin defined the group as the most recent common ancestor of Pterodaustro guinazui and Quetzalcoatlus northropi, and all its descendants. [8] This group was named for the presence of a head crest in most known species, though this feature has since been found in more primitive pterosaurs and was probably an ancestral feature for all ...

They assigned it to Quetzalcoatlus northropi and mistakenly identified it as a femur. A wingspan of 13 m (43 ft) was estimated. A wingspan of 13 m (43 ft) was estimated. [ 5 ] [ 2 ] However, nowadays, wingspan estimates for Q. northropi have been more moderate, at around 10 to 11 m (33 to 36 ft), which would still make it one of the largest ...
The size of Hatzegopteryx was initially estimated by comparing the 236 mm (9.3 in) humerus fragment with that of Quetzalcoatlus northropi, which has a 544 mm (21.4 in)-long humerus. Observing that the Hatzegopteryx fragment presented less than half of the original bone, Buffetaut and colleagues established that it could possibly have been ...
