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.This is referred to as dating by association with they underwent relatively rapid evolutionary changes that are identifiable in their teeth and other skeletal parts.Their bones also were frequently found in association with our human and primate ancestors.(length = 7 mins, 24 secs) The perpetrator of the Piltdown Man hoax may have been uncovered.In the mid 1990's, an old tool kit was found in a dusty backroom of the Natural History Museum in London.We will never know whether he was really the perpetrator, but he is now the leading candidate.
This is due to the fact that one or both of the objects may have been moved or redeposited into a different location.
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.
For instance, if we find a fossil bone below the strata 3 rock level shown above, we assume that the animal most likely lived at a time before that layer was formed.
However, we must be careful to note whether or not the fossil comes from the mixed strata zone of the filled in hole..
