Geology relative dating techniques
At the same time, percolating ground water deposits trace amounts of fluorine and other elements, such as uranium, into the bone.
As a result, the amount of fluorine Fluorine analysis can be used only as a relative dating method because the rate of decay and the amount of dissolved minerals in the ground water varies from site to site.
As time passes, the organic components of bone (mostly fat) are lost primarily through bacterial action.
Since these components contain nitrogen, there is a progressive loss of that element.
The jaw was likely to have come from a modern young adult orangutan.It contained tools and chemicals that could have been used to modify the ape jaw and human skull to give them the appearance of great antiquity.The owner of this kit was Martin Hinton, curator of zoology at the time of the hoax.It had been cleverly carved to fit the skull and stained to look ancient.In addition, the associated bones from extinct animals had much older fluorine and nitrogen ratios than either the jaw or the human skull.
