Worlds Biggest Mystery.. May Have Been Discovered...[Watch] Every single piece fits. Now, of course, we have to go through the whole archeological process, and we plan to do that within the next few months, but I feel very confident that weve discovered the site, he told CNN. This is the ship that changed the course of human history, Clifford said. If the claim is confirmed, it would go down as one of the most significant underwater archaeological discoveries ever. It is the Mount Everest of shipwrecks for me, said Clifford, 68. But it isnt a new find for him. Cliffords announcement involves a wreck he and his team investigated in 2003. A cannon was found as part of the wreck. But, Clifford told CNN, archaeologists at the time misdiagnosed the cannon. The ship still has attributes that warrant an excavation to determine the sites identity, archaeologist Charles Beeker of Indiana University said Tuesday. Barry may have finally discovered the 1492 Santa Maria. The evidence, Beeker said, is very compelling.
