In this week's Proceedings of the National Academy of Sciences, researchers shows that carbon-14 levels can be used to determine when an animal died to within about one year. The researchers make use of the fact that the levels of carbon-14 in the atmosphere from the mid-1950s, during the era of Cold War nuclear tests, are precisely known, and are taken up in different amounts by animals depending upon the years in which they lived.
