Study tracks elephant tusks from 16th century shipwreck

In 1533, the Bom Jesus – a Portuguese trading vessel carrying 40 tons of cargo including gold, silver, copper and more than 100 elephant tusks – sank off the coast of Africa near present-day Namibia. The wreck was found in 2008, and scientists say they now have determined the source of much of the ivory recovered from the ship.

Online tool speeds response to elephant poaching by tracing ivory to source

A new tool uses an interactive database of geographic and genetic information to help authorities quickly identify where the confiscated tusks of African elephants were originally poached.
