Is this fragile jawbone a pterosaur or not? Other researchers also had questions about the fossil, unearthed along with thousands of others during a decades-long archaeological dig at a remote bone bed in the Petrified Forest National Park in Arizona.

Scientists have discovered a new species of pterosaur – a flying reptile that soared above the dinosaurs more than 200 million years ago. The jawbone of the ancient reptile was unearthed in the US back in 2011, but modern scanning techniques have now revealed details showing that it belongs to an entirely new species.

Paleontologists have uncovered in Arizona a Triassic treasure trove of fossils dating back 209 million years ago.
