<span style="color: #222222;">An ancient Greek trading ship dating back more than 2,400 years has been found virtually intact at the bottom of the Black Sea.&nbsp; The vessel is one of more than 60 shipwrecks including Roman ships and a 17th-century Cossack raiding fleet identified by the Black Sea Maritime Archaeology Project. </span><br />” <br />” <span style="color: #222222;">During the three-year project, researchers used specialist remote deep-water camera systems previously used in offshore oil and gas exploration to map the seafloor. </span><br />” <br />” <span style="color: #222222;">The ship, which is lying on its side with its mast and rudders intact, was dated back to 400 BC — a time when the Black Sea was a trading hub filled with Greek colonies.</span><br />” <span style="color: #222222;">The project team said the vessel, previously only seen in an intact state on the side of ancient Greek pottery, was found at a depth of more than 2,000 metres (6,500 feet). </span><br />” <br />” <span style="color: #222222;">The water at that depth is oxygen-free, meaning that organic material can be preserved for thousands of years. The project's main investigator said that this would change the understanding of shipbuilding and seafaring in the ancient world.</span><br />
