Quetzalcoatlus northropi is an azhdarchid pterosaur known from the Late Cretaceous of North America (Maastrichtian stage) and one of the largest known flying animals of all time. It is a member of the family Azhdarchidae, a family of advanced toothless pterosaurs with unusually long, stiffened necks. Its name comes from the Mesoamerican feathered serpent god, Quetzalcoatl. Recent estimates based on greater knowledge of azhdarchid proportions place its wingspan at 10-11 meters (33-36 ft). Based on its wingspan, its height would have been at least 3 meters (10 feet). Older sudies give extremely low weight estimates for Quetzalcoatlus, was as low as 70 kilograms (150 lb) for a 10-meter (32-foot-10-inch) individual. A majority of estimates published since the 2000s have been higher, around 200-250 kilograms (440-550 lb).
