In the past, relative dating methods often were the only ones available to paleoanthropologists.

In other words, the biochemical clock that this method relies on runs at a different rate in different environments.

Fluorine analysis is primarily used for verifying whether or not two fossils in the same strata at a site were in fact contemporaneous.

It was popularly referred to as "the missing link" in human evolution.

In This was verified through the use of X-ray fluorescence examination.

Relative dating is the process of determining the age of an artifact, a layer of rock, a fossil, or something else by using the position of that item in relation to other surrounding rock layers and items.

(Remember, we are only able to determine whether something is older or younger compared to something else.) See this link for a thorough review of how relative dating is done.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.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.However, the assumption of contemporaneity may not always be correct.
