A three-dimensional scan of the Titanic this month found a necklace among the wreckage. It is a piece of jewelry consisting of a tooth from a prehistoric shark, the megalodon.

It lies at the bottom of the sea since the luxury ship sank in the Atlantic after colliding with an iceberg, on April 15, 1912. Magellan, which has digitally recreated the ship by recording and photographing it with two small submarines, has made the discovery of the jewel. The company wants to know more about this necklace and know its owner as well as its possible heirs.
