Is it a bird? Is it a plane? No, it's potentially one of the largest flying reptiles to have ever graced our planet, with a wingspan measuring over 36 feet (or 11 metres).
Paleontologists at the University of Tokyo first discovered hints of this animal when they dug up eight-inch bone fragments in Mongolia in 2006, but have since spent a decade trying to decipher exactly what it is they were looking at.
Now though they have revealed that it is in fact evidence of the largest pterosaur ever to exist.
