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 ...

Valles Marineris (/ ˈ v æ l ɪ s m ær ɪ ˈ n ɛər ɪ s /; [1] Latin for Mariner Valleys, named after the Mariner 9 Mars orbiter of 1971–72 which discovered it) is a system of canyons that runs along the Martian surface east of the Tharsis region. [2]
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 ...
