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 what is now North America. The first specimen, recovered in 1971 from the Javelina Formation of Texas, United States, consists of several wing fragments.
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]
Within Azhdarchoidea, two big groups have largely been consistent, the first one consisting of pterosaurs more closely related to tapejarids, such as Tapejara, while the second one comprising pterosaurs more closely related to azhdarchids, such as Quetzalcoatlus. Over the years, new clades within Azhdarchoidea have been named following the ...
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 ...
Quetzalcoatl—he was the wind, the guide and road sweeper of the rain gods, of the masters of the water, of those who brought rain. And when the wind rose, when the dust rumbled, and it crack and there was a great din, became it became dark and the wind blew in many directions, and it thundered; then it was said: "[Quetzalcoatl] is wrathful." [17]
Lawson began his synecological research during his master's degree studying the paleoecology of the Tornillo Formation in Big Bend National Park, Texas.During his study of this Late Cretaceous intermontane basin community, he discovered the fossil remains of the giant pterosaur, Quetzalcoatlus Northropi, which he named in honor of John K. Northrop because of its similarity to Northrop's flying ...
