The report then gives a method by which original bioapatite can be extracted from a fossil. When you also consider the fact that many other dinosaur bones (and other things that are supposed to be millions of years old) are dated as only being 22,000-41,000 years old, you have to at least conclude that there is something wrong somewhere.Either the carbon-14 dating system is not as robust as some want to believe, or the fossils are not as old as some want to believe.
It is possible to calculate the age of a sample by measuring the uranium content and the density of the fission tracks.Instead, the fossil’s bioapatite (a mineral found in bone) was dated.According to a 2009 report in the journal Contamination of the organic fraction in the process of the burial or during museum preservation treatment generally prohibits the use of the collagen fraction for dating.Different methods have their own limitations, especially with regard to the age range they can measure and the substances they can date.
A common problem with any dating method is that a sample may be contaminated with older or younger material and give a false age.Our investigation has shown that the pretreatment of bone with diluted acetic acid following a proscribed technique allows the separation of the bioapatite fraction from diagenetic carbonates. The lab might not have been able to completely isolate the fossil’s original bioapatite, so the result may have contamination in it.
