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.
In 1994 Bennett defined a clade Pteranodontidae, also including species of the Ornithocheiromorpha. [4] However, this definition has not been accepted by other workers. Alexander Kellner, for example, named several additional species for specimens previously classified as Pteranodon , and placed P. sternbergi in a distinct genus, Geosternbergia .
Pteranodon sternbergi is the only known species of Pteranodon with an upright crest. The lower jaw of P. sternbergi was 1.25 meters (4.1 ft) long. [47] It was collected by George F. Sternberg in 1952 and described by John Christian Harksen in 1966, from the lower portion of the Niobrara Formation.
Azhdarchidae (from the Persian word azhdar, اژدر, a dragon-like creature in Persian mythology) is a family of pterosaurs known primarily from the Late Cretaceous Period, though an isolated vertebra apparently from an azhdarchid is known from the Early Cretaceous as well (late Berriasian age, about 140 million years ago).

Least-inclusive clade containing Anhanguera, Pteranodon, Dsungaripterus, and Quetzalcoatlus: Previously defined as the least-inclusive clade containing both Pteranodon and Istiodactylus (this clade is now called Pteranodontoidea - see below) Ornithocheiromorpha: Andres et al., 2014 [3] Most-inclusive clade containing Ornithocheirus but not ...
The skybax (Quetzalcoatlus skybax) is a fictional creature in the Dinotopia fantasy book series. In the series, it carries "skybax riders" to their destination, although the skybax itself does the steering. The master pilot that trains the riders in the books is Oolu, one of the Aerial Habitat Partners.
Azhdarchoidea (/æʒdɑːrˈkɔɪdɪːə/, meaning "azhdarchid-like forms") is a group of pterosaurs within the suborder Pterodactyloidea.Pterosaurs belonging to this group lived throughout the Early and Late Cretaceous periods, with one tentative member, Tendaguripterus, that lived in the Late Jurassic period.
In 2010, Brian Blake Andres wrote a review of pterosaur phylogeny in his dissertation.His phylogenetic analysis combined data mainly from three different matrixes: Kellner's original analysis (2003) and its updates (Kellner (2004), Wang et al. (2005) and Wang et al. (2009)), Unwin's original analysis (2003) and its updates (Unwin (2002), Unwin (2004), Lu et al. (2008) and Lu et al. (2009)) and ...
