Such contamination would, however, reduce the apparent age of a 60,000-year-old object by almost 50 percent.

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.

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 ).

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

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.

) are about what one would expect to find in hydroxyapatite and calcite, two of the commonest minerals present in ordinary dinosaur fossils.
