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.
Pterosaurs included the largest flying animals ever to have lived. They are a clade of prehistoric archosaurian reptiles closely related to dinosaurs. Species among pterosaurs occupied several types of environments, which ranged from aquatic to forested. Below are the lists that comprise the smallest and the largest pterosaurs known as of 2022.
[10] [11] At the time of description, Argentavis was the largest flying bird known to have existed but it has since been exceeded by another extinct species, Pelagornis sandersi, in wingspan, which the 2014 description estimated at 7 to 7.4 m (23 ft 0 in to 24 ft 3 in).
Although it is widely thought that Quetzalcoatlus reached the size limit of a flying animal, the same was once said of Pteranodon. The heaviest living flying animals are the kori bustard and the great bustard with males reaching 21 kilograms (46 lb). The wandering albatross has the greatest wingspan of any living flying animal at 3.63 metres ...
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 blue whale is the largest mammal of all time, with the longest known specimen being 33 m (108.3 ft) long and the heaviest weighted specimen being 190 tonnes. [ 15 ] [ 60 ] [ 61 ] The extinct whale species Perucetus colossus was shorter than the blue whale, at 17.0–20.1 meters (55.8–65.9 ft) but it is estimated to have rivaled or ...
Dearc (Scottish Gaelic pronunciation: dearc ⓘ) is a genus of large-bodied rhamphorhynchine pterosaur from the Middle Jurassic Lealt Shale Formation of Scotland.The holotype, a juvenile or subadult that was still actively growing, has an estimated wingspan of 2.5 to 3 meters, making it the largest flying animal of its time.
Ardeotis kori kori flying near Windhoek, Namibia. They are arguably the largest or one of the largest extant flying animals. Kori bustards spend most of their time on the ground, with up to 70% of their time being on foot, [3] although they do occasionally forage in low bushes and trees. This bustard is a watchful and wary bird.
