Divers have found timbers they believe to be remains of the world's oldest known ship off Hayling Island near Portsmouth, England. Radiocarbon dated to 6,431 years ago, the timbers were discovered in 30 feet of water by a team led by British sport diver Don Boullivant. "We have been searching the area for quite some time, looking for Roman wrecks," says Boullivant. "When we came across the worked oak timbers, we were certain that we had finally found one. To our great surprise the wood is older by 4,000 years."
