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.

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