I read an interesting article a couple of years ago wherein it was postulated that because an elephant's tusk absorbs radioactive carbon deposited in the air by cold war nuclear tests, researchers could test a sample of recovered ivory to determine when the elephant was killed--the premise is that with the passing of each year, the amount of radiocarbon in the atmosphere declines slightly, with trace amounts being absorbed by an elephant's tusk.
