This is referred to as dating by association with they underwent relatively rapid evolutionary changes that are identifiable in their teeth and other skeletal parts.

Their bones also were frequently found in association with our human and primate ancestors.

This relative dating method is based on the fact that there are specific progressive chemical changes in skeletal remains that result from burial underground.With out individual time stamps the process of dating these structures could become extremely difficult.To deal with many of these problems geologists utilize two types of geologic time: relative time and absolute time.This means that a quartz sandstone deposited 500 million years ago will look very similar to a quartz sandstone deposited 50 years ago.Making this processes even more difficult is the fact that due to plate tectonics some rock layers have been uplifted into mountains and eroded while others have subsided to form basins and be buried by younger sediments.
