　　The oldest intact shipwreck has been found in the Black Sea, archaeologists from an Anglo-Bulgarian expedition claimed on Tuesday.

　　A group of archaeologists and scientists belonging to the Black Sea Maritime Archaeology Project (Black Sea MAP) have said that they have found a ship on the sea floor which they have successfully radiocarbon dated to 400BC.

　　The group recorded images of the wreck using remote deep-water cameras.

　　Originally found in 2017, the group describes the ship as "a Greek trading vessel". Archaeologist Dragomir Garbov said its discovery provided a glimpse of "the last moment in the life of a ship".

　　The team has been led by the University of Southampton and the National Institute of Archaeology with Museum of the Bulgarian Academy of Sciences.

　　A documentary chronicling the team's exploits was shown at the British Museum in London on Tuesday.
