And as elephants ate and grew, laying layers of toothy material called dentine onto their tusks, so was the carbon-14 locked away.When an elephant died, carbon-14 was no longer sequestered in its tusks.Environment Canada used the new technique for the first time to convict Toronto-based Five Star Auctions and Appraisals, and company director Chun Al Jin, in February, the department said in a news release this week.The company and Jin were each hit with a penalty of ,375, or a total of ,750, and had to hand over two tusks to authorities.In November 2013, Environment Canada enforcement officers learned that two carved elephant ivory tusks--measuring 78 cm and weighing 1.7 kg each--were being offered for sale by a Toronto-based auction house, which claimed the tusks were “antique”.Acting on legal authority, officers temporarily detained the tusks and, using radiocarbon dating technology, both were analyzed by experts at Université Laval and Columbia University.

A 2014 study found poachers killed about 100,000 African elephants for their ivory between 20.
