A diver has discovered a six inch long shark tooth while out at sea.
Michael Nastasio, owner of Black Gold Fossil Charters, found the tooth in Venice, Florida.
He was so excited about his find that he actually had to cut the dive short because he couldn't catch his breath.
Nastasio, who has been diving for nine years, has found many fossils such as mammoth teeth still in the jaw bone, sections of tusk, many other species of shark teeth, camel teeth, bison teeth, horse teeth and sloth teeth.
Speaking to ABC, he said: "When I saw the tooth exposed like it was it literally took my breath away. I was so excited."
If you're impressed about a shark tooth, this might just blow your mind. Back in October, divers found a sunken Nazi ship which might contain missing panels from a long-lost Amber Room which are said to be worth £250 million.
The Amber Room was a 'dazzling space panelled with tonnes of finely carved amber, gold, and jewels dubbed by some an eighth wonder of the world', according to Radio Free Europe.
It was originally created for King Frederick I of Prussia, all the way back in the 1700s but the treasure disappeared after being looted by Nazis during the war.
Experts are hopeful the sunken ship, which was discovered by Polish divers two months ago, has the remains.
The divers, from Baltictech, say the Karlsruhe is almost intact and have spent the past few months exploring it.
They explained: "The wreck rests several dozen kilometres north of Ustka at a depth of 88 meters. It is practically intact. In its holds, we discovered military vehicles, porcelain and many crates with so far unknown contents.
"This discovery may provide ground-breaking information on the disappearance of the legendary Amber Room, because it was in Königsberg that it was last seen.
"From there, the steamer Karlsruhe set out on its last voyage with a large cargo."
Baltictech continued: "After a thorough inspection of the seabed around Karlsruhe, we were able to confirm the presence of a second wreck, only 550 metres away from 'our' steamer.
"Further research will show whether it is a unit related to the events of April 13, 1945. As we expected, a lot of equipment spilled around the wreck, especially in front of its bow.
"At the bottom, we found ten chests and a lot of other trinkets. Some of the chests were open. The content of one of them - special rubber gaskets - gives you hope that they are some valuable items, maybe paintings?"
