A remotely operated submarine was collecting samples on a previously unexplored deep sea mountain when it scooped up a rare megalodon tooth.
The gold-colored tooth, which is 2.7 inches (6.8 centimeters) long, was discovered more than 10,000 feet (3,090 meters) below the surface near the Johnston Atoll in the Pacific Remote Islands Marine National Monument, around 800 miles (1,300 kilometers) south of the Hawaiian Islands.
