SHOCKED scuba divers have found a huge 50 pound mammoth bone in a Florida river.
The two men were diving in the Peace River when they made the Ice Age discovery.
Derek Demeter and Henry Sadler found the ancient bone which stands at four foot high.
Demeter, Seminole State Planetarium's director, : "Henry is my dive buddy.
"He yelled out to me, said, 'Hey, Derek. I found something!' Oh my goodness!' It was really, really cool."
The divers think the bone belonged to to a Columbian mammoth.
It may have been roaming around Florida anytime between 2.6 million and 10,000 years ago when conditions where much more cold and icy.
Experts may find it tricky to determine its precise age.
Demeter : "This one's much more dense, so we kind of think it's somewhere in the middle. Probably 100,000 years old."
The two men also discovered parts on an extinct shark and a sabre tooth tiger tooth on the same day.
They consider themselves amateur palaeontologists and are often making amazing discoveries.
Demeter said: "The thing I love about it is, just like astronomy, it's time traveling. It plays with the imagination so you go 'Wow, what was going on at this time?"
The mammoth bone find may head to a museum one day but for now it's heading for Sadler's classroom so he can teach his students about the Ice Age.
