World's oldest intact shipwreck found in Black Sea

Researchers say the ancient Greek trading ship found at the bottom of the Black Sea near Bulgaria is the world's oldest known shipwreck

An ancient Greek trading ship 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 vessel is one of more than 60 shipwrecks identified by the Black Sea Maritime Archaeology Project including Roman ships and a 17th-century Cossack raiding fleet.
