A shipwreck uncovered in 2008 in Namibia held more than a hundred elephant tusks, which has now enabled researchers to trace back where those elephants had lived, Gizmodo reports.
The boat, the Bom Jesus, was a Portugese merchant vessel that went missing in 1533 while on its way to India, it adds, noting that it was laden with not only ivory, but also gold, silver, tin, and copper.
