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.
The largest of non-pterodactyloid pterosaurs as well as the largest Jurassic pterosaur [16] was Dearc, with an estimated wingspan between 2.2 m (7 ft 3 in) and 3.8 m (12 ft). [17] Only a fragmentary rhamphorhynchid specimen from Germany could be larger (184 % the size of the biggest Rhamphorhynchus ). [ 18 ]
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 ...
[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).
Many of the largest flying birds in the fossil record may have been members of the Ciconiiformes. The heaviest flying bird ever, Argentavis magnificens, is part of a group, the teratorns, that is considered an ally of the New World vultures. [86] The largest ibis is the giant ibis (Thaumatibis gigantea). Adults can grow to 102–106 cm (40–42 ...
The table contains a list of the largest birds living on this planet by wingspan, at maximum, assumed to be reliable by experts and verified records, at least 3 m (9 ft 10 in). Rank Image
The Andean condor is the largest living land bird capable of flight if measured in terms of average weight and wingspan, although male bustards of the largest species (far more sexually dimorphic in size) can weigh more. [14] [19] [20] The mean wingspan is around 283 cm (9 ft 3 in) and the wings have the largest surface area of any extant bird ...
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 ...
