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 ...
Size comparison of Q. northropi (green), Q. lawsoni. (blue), and a human. This is a list of pterosaurs with estimated maximum wingspan of more than 5 meters (16 feet): ...
The former contains azhdarchids closer related to Azhdarcho and are smaller in size, while the latter contains azhdarchids closer to Quetzalcoatlus and are much larger in size. [20] The second cladogram is by Xuanyu Zhou and colleagues in 2024, [22] which is based on the phylogenetic analysis by Rodrigo Pêgas in the same year. [21]
A Mesozoic reptile is believed to have been the largest flying animal that ever existed: the pterosaur Quetzalcoatlus northropi, from North America during the late Cretaceous. This species is believed to have weighed up to 126 kg (278 lb), measured 7.9 m (26 ft) in total length (including a neck length of over 3 m (9.8 ft)) and measured up to ...
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 ...
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]
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 ...
