Researchers say they've identified a fossil unearthed more than 30 years ago as the largest flying bird, well, ever.
Time to run and hide, everyone.
Well, maybe not.
The fossil, dug up near an airport in South Carolina is being called the ultimate Big Bird.
The Pelagornis sandersi took to the skies about 25 million years ago, with a wingspan of about 6.4 meters wide.
This makes it about twice the size of the royal albatross, the largest living bird.
Other than size, what really sets it apart from birds today is that it has a spiky beak that looked like teeth.
Ok, maybe it is a little freaky.
