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.However, the assumption of contemporaneity may not always be correct.

In other words, they may no longer be in their primary context.When the bones of our early ancestors are found in the same geological strata as those of other animals that are known to have lived only during a specific time period in the past, we assume that these ancestors must also have come from that time.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.These processes result in All of these processes confuse the stratigraphic record.

In many cases, however, it is possible to reconstruct the original sequence of strata so that they can be used for relative dating.

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 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.

The skull and jaw clearly were not from the same time period.
