Remember the reports in May that a shipwreck off Haiti was likely Christopher Columbus's Santa Maria? UNESCO researchers say nope.
…The U.N. cultural agency UNESCO said in a report Monday that bronze or copper fasteners found at the site point to shipbuilding techniques of the late 17th or 18th centuries, when ships were covered in copper. Before that, fasteners were made only of wood or iron, it said.
"There is now incontestable proof that the wreck is from a much later period," according to the report by mission leader Xavier Nieto Prieto, who visited the site for several days beginning September 9.
