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.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.

There is absolutely nothing unusual about these fossils and no reason to think the carbon contained in them is organic carbon derived from the original dinosaur bone.

Robert Kalin senior research specialist at the University of Arizona’s radiocarbon dating laboratory, performed a standard independent analysis of the specimens submitted by Hugh Miller and concluded that the samples identified as “bones” did not contain any collagen. These results corroborated established paleontological theories that assert that these fossiles presumably were 'washed away' over long periods of time by ground water, replacing the original bones with other substances such as the minerals naturally present in the water, implying that this sample could ).

These, together with many other remarkable concordances between samples from different fossils, geographic regions and stratigraphic positions make random contamination as origin of the C-14 unlikely".

There is a lot of discussion about this issue on this internet, so I think this question may be worth addressing seriously.

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.

Daniel Fisher of the University of Michigan’s Museum of Paleontology examined these results and concludes that there is nothing whatsoever extraordinary about them.

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.

At this point, it is quite clear that there is little reason to trust the research by Miller's research group.

In fact, the article by Leppert raises a number of additional issues (e.g.

He said that his team and the laboratories they employed took special care to avoid contamination.
