Some of the biggest flying animals in the history of the planet were azhdarchid pterosaurs, such as Quetzalcoatlus, whose wingspan exceeded 30 feet (9 meters). Hatzegopteryx was certainly in that class, with a wingspan thought to have been up to 39 feet (12 meters).
In addition to the breadth of wing, azhdarchids are typically known for having had long necks and jaws. The behemoths foraged on the ground for small prey such a baby dinosaurs.
Hatzegopteryx, though, throws those characteristics for a bit of a loop, wrote Darren Naish, of the University of Southampton, and Mark Witton, of the University of Portsmouth, in the journal Peer J.
Thanks to a Late Cretaceous neck vertebra fossil from 66-70 million years ago found in Romania, it turns out that Hatzegopteryx was especially thick of neck, for a pterosaur, showing that some azhdarchids could appear proportionally much different than the conventional picture of the animals:
|(A) Two giant, long-necked azhdarchids argue over a small theropod; (B) the similarly sized but more powerful Maastrichtian, Transylvanian pterosaur Hatzegopteryx sp. preys on rhabdodontid iguanodontian Zalmoxes.|
