This Freaky Discovery In Alaska Is The Stuff Of Nightmares

In 1986, a young geology student named Richard Glenn made a discovery a strange looking fossil in a chunk of rock near Atigun Gorge. The fossil was sent to the Smithsonian Institute where it was identified as the teeth whorl of a Helicoprion, an extinct predatory fish that is estimated to have lived about 280 million years ago. The jaw bone of the creature resembles a circular chop saw, giving the creature it’s common name: the Buzz Saw Shark!

Although the Helicoprion is not a descendant of the modern day shark, nor do current theories support the jaw bone spinning like a buzz saw, this enormous, ancient fish is still fascinating. And for some reason, one was wandering around in the farthest reaches of Alaska.

Here is a scholarly article in Biology Letters about the Helicoprion.
