Carbon dating of fossils older than 10,000 years

  1. Apr 27, 2006 #1
    I'm just wondering, is it fine to predict the age of fossils older than 10,000 years with Carbon Datin? After all, I think nobody knows how much carbon-14 there was back then, and whether the animals consumed less or more carbon-14 than now. How exact are such long-term predictions?

    Anything older you'll need to use potassium-40.
