Meet the "Dragon of Death."
Scientists in Argentina discovered the fossils of a flying reptile in the Andes mountains.
They said it had a 30-foot wingspan and lived 86 million years ago alongside dinosaurs.
Researchers said it was the largest animal that flew in the skies around South America.
They believe it's a new species of pterosaurs, which predate birds and are often confused with dinosaurs.
But there's no evidence the reptile breathed fire.
