Any item that derives from a previously living organism—for example, a basket made of plant fibers or a scrap of animal hide—can be subjected to carbon-14 dating.The technique is useful for dating items up to about 50,000 years old. Let's look at their research methodology in detail (indicated by bullet points): Let's take a little pause to consider the general issue of misrepresenting your own research. did this, since there would have been a slim chance (at best) of the museum curator providing them with any dinosaur bone fragments if he or she had known what the true intent of the supposed chemists was.In particular, it is implausible that it would have been considered worthwhile to try to use radiocarbon dating methods on these bones, since the rocks that they were taken from were determined to be 99 million years old, as shown in this paper by Kowallis et al.The particular example you bring up is one of the most famous such cases.

Contamination of this kind amounting to 1 percent of the carbon in a sample 25,000 years old would make it appear to be about 1,500 years younger than its actual age.Furthermore, it appears less than certain that the carbon found in the bones actually had anything to do with them being dinosaur bones.In the article by Leppert, we find: Hugh Miller generously provided me with a copy of the elemental analysis of one of their dinosaur fossils.Radiometric dating is a method of dating based on the rate of decay of radioactive isotopes present in all organic materials.The radiometric dating technique used most widely in archaeology is radiocarbon, or C-14, dating.If dinosaur bones are 65 million years old, there should not be one atom of C-14 left in them.
