Oldest intact shipwreck found in Black Sea

LONDON - A Greek trading vessel dating back more than 2,400 years has been found virtually intact at the bottom of the Black Sea, the world's oldest known shipwreck, researchers said on Tuesday.

The ship is one of more than 60 wrecks identified by the Black Sea Maritime Archaeology Project including Roman ships and a 17th-century Cossack raiding fleet.

During the three-year project, researchers used specialist remote deep-water camera systems previously used in offshore oil and gas exploration to map the sea floor.
