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.
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.
It was popularly referred to as "the missing link" in human evolution.
In This was verified through the use of X-ray fluorescence examination.The skull and jaw clearly were not from the same time period.The jaw was likely to have come from a modern young adult orangutan.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.Unfortunately, by 195 Piltdown Man Hoax--an explanation of one of the greatest frauds in the history of science This link takes you to an audio file at an external website.
