Dating beyond the 40,000 to 60,000 year threshold using radioactive carbon is problematic -- even with the most advanced detection instrumentation -- because so little carbon-14 remains in a sample after that time after 5,730 years, a decaying piece of organic matter will contain half of the carbon-14 it died with.
