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.

Now, it is known that $^\text$ decays at a fast enough rate (half-life ~6000 years) for this dating method to be absolutely useless on such samples. would not have been able to obtain this sample, had they been honest about their intent.

It's accuracy has been verified by using C-14 to date artifacts whose age is known historically.

The fluctuation of the amount of C-14 in the atmosphere over time adds a small uncertainty, but contamination by "modern carbon" such as decayed organic matter from soils poses a greater possibility for error. Thomas Seiler, a physicist from Germany, gave the presentation in Singapore.

Clearly proper sample decontamination procedures are of particular importance in the dating of very old artifacts It is clear that the sample provided by Miller did not under go any 'sample decontamination procedures' at all, and it is therefore strongly questionable to which extent it can be used to obtain a good estimate of the age of the bones.

Furthermore, it appears less than certain that the carbon found in the bones actually had anything to do with them being dinosaur bones.

The main point of the debate seems to be the following: Over the past decades, several research groups of self-proclaimed creationist scientists have claimed discoveries of dinosaur bones that they have managed to date, using radiocarbon dating methods, at some age which is a lot below the 'usual' i.e.

mainstream accepted date for the age of these bones (several dozens of million 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.

Knowing that small concentrations of collagen can attract contamination, they compared precision Accelerator Mass Spectrometry (AMS) tests of collagen and bioapatite (hard carbonate bone mineral) with conventional counting methods of large bone fragments from the same dinosaurs.
