A diver in the US state of Florida has found a giant prehistoric shark tooth during a weekend trip out to sea.
Mike Nastasio runs Black Gold Fossil Charters out of Venice and regularly takes groups out on the water to go searching for megalodon shark teeth.
The region is known for its shark teeth and Mr Nastasio's recent find is believed to be one of the biggest on record for the area.
Mr Nastasio said the teeth measured about 14 centimetres in a Facebook post showcasing his find.
"I had to cut my dive short because I could not catch my breath after snatching it up," he said.
Mr Nastasio has been diving in the area for nine years according to Black Gold Fossil Charter's site.
The biggest sharks caught, tagged and studied around the world
During this time he has found other ancient things like mammoth teeth, sections of tusk as well as shark teeth, Bison teeth, camel teeth and horse teeth.
The largest confirmed megalodon tooth discovered was 7.48 inches (18.9cm) long and was located near Ocucaje, Peru according to fossilera.com.
