The theoretical limit for C-14 dating is 100,000 years using AMS, but for practical purposes it is 45,000 to 55,000 years. If dinosaur bones are 65 million years old, there should not be one atom of C-14 left in them. Dinosaurs are not dated with Carbon-14, yet some researchers have claimed that there is still Carbon-14 in the bones.

Once the organism dies, however, it stops incorporating new carbon, and the ratio between carbon-12 and carbon-14 begins to change as the carbon-14 decays to form nitrogen-14. Therefore, a scientist can use the ratios of carbon-12, carbon-14, and nitrogen-14 to estimate the age of an organic sample. This method is known as radiocarbon dating.
