Stratigraphic excavation is the recording and study of these different strata as they are removed from the area. Relative dating is used to determine a fossils approximate age by comparing it to similar rocks and fossils of known ages. In a hypothetical example, a rock formation contains fossils of a type of brachiopod known to occur between and million years. There are relatively few dating laboratories and having an artefact dated can be an expensive exercise especially if the artefact is not of great value itself. Scientists can use certain types of fossils referred to as index fossils to assist in relative dating via correlation. Landslides and slips can completely change the topography of an entire archaeology site burying what was once on top by that which is much older, hence reversing the strata layers. Unsourced material may be challenged and removed. Although both relative and absolute dating methods are used to estimate the age of historical remains, the results produced by both these techniques for the same sample may be ambiguous. This technique dates the time period during which these rings were formed. Thus, measuring the ratio of D to L in a sample enables one to estimate how long ago the specimen died.
