We will never know whether he was really the perpetrator, but he is now the leading candidate.
Another candidate was a famous practical joker who lived near the Piltdown gravel deposit during the early 20th century.
If not, then at least one of them must be physically out of context.
it had an ape-like jaw and was found in association with the bones of extinct animals, this "Piltdown Man" was also believed to be a very ancient human.
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.
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..
In the mid 1990's, an old tool kit was found in a dusty backroom of the Natural History Museum in London.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.can be used to tell us whether or not the animals they were from actually lived at about the same time.This relative dating method is based on the fact that there are specific progressive chemical changes in skeletal remains that result from burial underground.That man was a medical doctor by training and therefore had the necessary skills to carry off the hoax.He was Sir Arthur Conan Doyle, the author of the Sherlock Holmes detective stories.In the past, relative dating methods often were the only ones available to paleoanthropologists.As a result, it was difficult to chronologically compare fossils from different parts of the world.It was popularly referred to as "the missing link" in human evolution.In This was verified through the use of X-ray fluorescence examination.
