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.
Cast of an assigned wrist bone. The first pterosaur remains from Romania were identified by Franz Nopcsa in 1899, and the first remains of Hatzegopteryx were found during a student dig in the late 1970s from the upper part of the Middle Densuş Ciula Formation of Vălioara, northwestern Hațeg Basin, Transylvania, western Romania, which has been dated to the late Maastrichtian stage of the ...
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).

Among living animals which fly over land, the Andean condor and the marabou stork have the largest wingspan at 3.2 metres (10 ft). Studies have shown that it is physically possible for flying animals to reach 18-metre (59 ft) wingspans, [ 21 ] but there is no firm evidence that any flying animal, not even the azhdarchid pterosaurs, got that large.
However, the pterosaurs had to share the skies with some remarkable flying dinosaurs like Microraptor. From these feathered flyers evolved the birds, who survived the K-Pg mass extinction. Some, like the swans, could gracefully fly at 30 mph as David Attenborough shows when he tracks their progress on a boat.
A Polish woman who claimed to be missing Madeleine McCann was arrested upon landing in the UK. Julia Wandelt, who also goes by Julia Wendell and Julia Faustyna, was taken into custody upon ...
The Quetzalcoatlus' huge wings hamper its escape in the forest as the T. rex bites its foot. The Quetzalcoatlus pecks at the T. rex's eye and flies away. One hatchling survives the attack. Two T. Rexes hear a mating fight between two Triceratops and attack the loser. Working together, they bring down the Triceratops and eat it.
However, it’s possible he could have been even older. The island’s veterinarian, Joe Hollins said in 2015, “We have a record that he was landed in 1882 fully grown. We are told that fully ...
