megalodon

A Florida man found a gigantic fossilized megalodon tooth while diving in Florida waters, months after getting attacked by a gator.

"It's my first whole megalodon tooth," said Jacob Danner, who spotted the fossil during an early morning walk.

Megalodons lived between 3.6 to 20 million years ago and could reach up to 49 feet in length.

The boy and his family were vacationing on a South Carolina beach when the huge fossil was uncovered.

Finder Matthew Basak hopes to sell the tooth for $6,000 or more. Many are already on sale for thousands.

Megalodon was the largest shark ever to have lived, potentially growing up to around 60 feet in length.

Missy Tracewell said she cried and jumped up and down "like a five-year-old" when she found the tooth of the prehistoric predator.

A 3-inch tooth was found on a dirt path in Eglin Reservation, northwest Florida. Paleontologists suspect it came from a quarry.

The megalodon could reach lengths of 48 to 60 feet and went extinct approximately 3 million years ago. A fossil of the prehistoric shark was found washed up in the sands of the Cayman Islands.

Some of the teeth could belong to the extinct shark megalodon—one of the largest and most powerful predators to have ever lived.

The ancient 60-ton mega-shark ruled the ocean for 20 million years before its extinction.

The megalodon shark once ruled Earth's oceans. Now, a fossilized tooth from the extinct apex predator has been found by a man on a beach who was walking his dog.

Scientists think the biggest ever shark was likely killed off at least a million years before current estimates,

Researchers link a supernova explosion 2.6 million years ago to the extinction of marine megafauna.

National Science Foundation has given researchers over $200,000 to find out why Megalodon was wiped out.

The real megalodon lived from about 16 million to 2.6 million years ago.

"I was immediately excited, it was just perfect, and I knew it was an important find that needed to be shared with people."

Megalodon could grow up to 18 meters in length and weigh as much as 37 tons.

You can almost taste the regret.

A newly discovered global extinction event resulted in 36 percent of marine megafauna going extinct.
