When the discovery of the fossils was reported in 1975, "Quetzalcoatlus" was the largest flying creature known to have lived. A fellow researcher challenged Lawson's estimates of the dimensions of the wing architecture of "Quetzalcoatlus". However, Lawson responded by demonstrating that while inconsistent with those of modern-day birds, his estimates were consistent with extrapolations of other pterosaurs, such as "Pterodactylus antiquus". In 2010 the U.S. National Park Service described "Quetzalcoatlus" as the world's second-largest known flying creature.
