At first it was assumed that the smaller specimens were juvenile or subadult forms of the larger type. The skull of this species for example, is unknown and instead the head of the contemporary Q. More recently, the azhdarchids were cast as stork-like terrestrial stalkers that picked up small animals while walking overland on dry ground. Eupterodactyloidea Basal eupterodactyloids Haopterus.

Quetzalcoatlus pictures and facts

Two species of this genus existed in the southern parts of North America, specifically in the Javelina Formation of Texas. Quetzacloatlus this terrestrial hunting, Quetzalcoatlus and kin were incredible aeronauts. This possible second species from Texas was provisionally referred to as a Quetzalcoatlus sp. Lawson, who discovered Q. Rather, they concluded that azhdarchids were more likely terrestrial stalkers, similar to modern storksand probably hunted small vertebrates on land or in small streams.

Quetzalcoaatlus by Julian Johnson Mortimer. An azhdarchid neck vertebra, discovered in from the Maastrichtian age Hell Creek Formationmay also belong to Quetzalcoatlus. The smaller species is Quetzalcoatlus sp, an animal just half as big as the giant species. Like all flying reptiles, they launched off the ground in a four-footed leap. It is a member of the family Azhdarchidaea family of advanced toothless pterosaurs with unusually long, stiffened necks. The Jim Pattison Quuetzalcoatlus.


This launch style was supported by an immense amount of power. Discovery of the Largest Flying Creature”. One of the most fascinating facts about Quetzalcoatlus is that it might not have been able to fly.

For a while, Quetzalcoatlus and kin were cast in the light of giant vultures that scavenged the carcasses of dinosaurs. Henderson argued that it may have been flightless.

These pterosaurs were all very large animals with long, pointed skulls and some had short crests at the backs of their heads. But the larger size of Q.

Yet it was concluded that neither azhdarchids nor any other flying reptiles were suited for skimming so the hypothesis was dropped. Quetzalcoatlus occupied the role of medium-level hunter. Lawson in announced the find in an article in Science. Archived from the original on March 8, Its short wings were not just thin membranes of skin, but densely packed muscle fibers called actinofibrils. It was approximately 18 feet long, had a wingspan of 36 feet and probably weighed around to pounds.

The holotype specimen of Q. Lawson had found the remains of the giant pterosaur while searching for the bones of this dinosaur, which formed an important part of its ecosystem.

Quetzalcoatlus by James Kuether. The largest and most famous of these aerial titans was Quetzalcoatlus. Cuspicephalus Darwinopterus Kunpengopterus Wukongopterus. Choosing the middle of three extrapolations from the proportions of other pterosaurs gave an estimate of 11 m, They speculate that Quetzalcoatlus may have remained on the ground and used its wings for support.

The display featured the most accurate pterosaur models constructed at the time; these models took into account the latest evidence based on skeletal and trace fossils from related pterosaurs.

The bigger one, the huge Quetzalcoatlus northropi stood as tall as a giraffe on the ground, more than five meters tall and weighed kilograms.
