Pterosaurs roamed the skies long ago as the first animals to evolve powered flight after insects – and in the Gobi Desert, scientists recently found the remains of one that could have been nearly as big as a small aircraft. The mbadive pterosaur lived around 70 million years ago and could have been one of the biggest pterosaurs to ever walk the Earth, with a 36-foot wingspan.
Pterosaurs were reptiles, according to the American Museum of Natural History. They were close cousins to dinosaurs, and some were as tiny as a paper airplane. But this new pterosaur was anything but tiny. An international team led by the University of Tokyo found what they described as fragmentary cervical vertebral elements. From these fossil bones they determined the creature was huge. No pterosaur that large had been found in Asia until this one.

The two biggest pterosaurs we know of are the Quetzalcoatlus, found in the 1970’s in Texas, and Hatzegopteryx, found in the 1990’s in Romania. These reptiles had wingspans of around 32 to 36 feet, and could have reached 18 feet high on the ground – around as tall as a big bull giraffe, according to National Geographic. Pterosaur expert of the University of Portsmouth Mark Witton, who was not a co-author on this study, said there’s a chance this new pterosaur could have been even bigger than those other two. The new pterosaur is part of a group called azhdarchids, though scientists are reluctant to say they come from a new species given the incomplete remains.
The pterosaur possibly ate baby dinosaurs, but could have been capable of taking prey the size of a human, according to Witton. It wouldn’t have been an apex predator, because it was alive alongside a 5.5 ton-relative of the Tyrannosaurus rex, Tarbosaurus – although the pterosaur probably wouldn’t have been lunch for those creatures because in mere seconds it could have hurled itself towards the sky from a standing start.
The Journal of Vertebrate Paleontology published the discovery online in October. Scientists from Mongolia, the United States, and Japan contributed to the research.
