Despite centuries of searching, the exact resting place of Captain Cook's ship Endeavour has been a mystery.
However, a team of Australian researchers believe they have found the area in which the wreckage sits at Newport Harbour, Rhode Island.
Cook sailed the ship on his voyage of discovery to Australia and New Zealand between 1768 and 1770 and it was later used by the British Navy in 1778 as part of the American War of Independence but it's whereabouts since have been an unknown.
Kevin Sumption, head of the Australian National Maritime Museum, said: "Early indications are that the team has narrowed the possible site for the wreck of HMB Endeavour to one site, which is very promising.
"A lot more detailed work, analysis and research has to happen before we can definitively say we have found the remains of James Cook's HMB Endeavour."
Endeavour became notable for being part of Cook's travels, which started Britain's links with Australia and New Zealand, ultimately leading to their colonisation.
In more recent times, a replica has been built which sits at Darling Harbour in Australia.
Captain Cook became the first European to reach the east coast of Australia when Endeavour landed at Botany Bay in April 1770, having left Plymouth almost two years previous
It was deliberately sunk in 1778 in Newport Harbour but the remains of the vessel have never been found.
