Witton, M. P. and Habib, M. B., 2010, The volancy, or not, of giant pterosaurs. Despite this terrestrial hunting, Quetzalcoatlus and kin were incredible aeronauts. An animal the size of Quetzalcoatlus could consume victims as large as small dinosaurs, picking them up in its huge toothless jaws. Quetzalcoatlus lived during the Late Cretaceous and resided in North America. Its short wings were not just thin membranes of skin, but densely packed muscle fibers called actinofibrils. Furthermore, comparing their takeoff to scaled up bats is irrelevant because they are quite different anatomically from bats. Skull material from the as of yet unnamed smaller species shows that Quetzalcoatlus had a long sharp beak, with no hook and the end, like a modern stork. No flying animal alive today comes close to their huge size.

They call it home. Quetzalcoatlus was a pterosaur who lived approximately 70 million years ago during the Cretacious Period. Quetzalcoatlus had large, bare flaps of skin for wings, not feathers like flying animals of today. A Reappraisal of Azhdarchid Pterosaur Functional Morphology and Paleoecology. Others think that they skimmed fish from the water to eat with, due to the similar shape in beak as modern-day skimmers. Flightlessness.

This is contrary to earlier skull material, which seemed to have shown an unusually blunt snout. Quetzalcoatlus, like all azhdarchids, was uniquely well-adapted for a terrestrial lifestyle among pterosaurs, with limbs closer to those of running ungulates like deer then to other pterosaurs. The volancy, or not, of giant pterosaurs. It had a 10 to 12 meters wing-span (33/40 feet), but was light in construction (~200 pounds)..

P., 2007, Titans of the skies: azhdarchid pterosaurs. They did claim it could have been twelve metres or more in wingspan but that was based on an estimated wingspan for Quetzalcoatlus itself of 11-12 metres. The Quetzalcoatlus tries to fly off, but its huge wings prevent it from flying off in the thick forest. One of the most fascinating facts about Quetzalcoatlus is that it might not have been able to fly.

A single leap could get one of these giants into the air, and it needed just a few flaps to keep it aloft. The medium-sized Istiodactylus evolved during the Cretaceous, and its contemporaries included the largest flying animals ever known, such as Pteranodon longiceps and Quetzalcoatlus northropi. How did Quetzalcoatlus Northropi fly? This suggests they spent significant amounts of time on the ground feeding on smaller prey. Habib, M. B. and Witton, M. P., 2010, Soaring efficiency and long distance travel in giant pterosaurs. This is the maximum weight limit for a flying animal, and only a few other azhdarchids come close to Q.northropi’s size. Despite this name, however, it is not believed that Quetzalcoatlus had feathers. Amaxingly enough, though, the earliest estimates managed to overpredict how large their wingspan was, at up to 70 feet across. Acta Geoscientica Sinica, 31 (1), 27-28.
