A 16th-century shipwreck is thought to be the oldest uncovered in Sub-Saharan Africa. The 500-year-old treasure ship was discovered off the Atlantic coast of Namibia on April 1st by diamond company Namdeb. Human remains, thousands of Spanish and Portuguese gold coins, and elephant tusks have been found already. Three bronze canons are thought to originate from early 16th-century Spain. Experts from Spain and Portugal are due to arrive at the site amidst speculation that the ship may be linked to Portuguese explorer Bartholomeu Dias. Thought to be the first European to sail round the Cape of Good Hope, Dias disappeared in 1500.
