Spanish archeologists have recovered a largely intact shipwreck dating back nearly 2,600 years. The 27-foot (8 m) long trading vessel was carrying lead ingots to an unknown destination when it sank off the coast of Mazarrón, Spain. It remained hidden in the sand just six feet (1.8 m) below the ocean surface until divers finally found it in 1994.
