Method of dating fossils

Far from being data, these dates are actually interpretations of the data.

As discussed before, the assumptions influence the interpretation of the data.

Techniques include tree rings in timbers, radiocarbon dating of wood or bones, and trapped charge dating methods such as thermoluminescence dating of glazed ceramics.

Coins found in excavations may have their production date written on them, or there may be written records describing the coin and when it was used, allowing the site to be associated with a particular calendar year.

Absolute dating provides a numerical age or range in contrast with relative dating which places events in order without any measure of the age between events.

In archaeology, absolute dating is usually based on the physical, chemical, and life properties of the materials of artifacts, buildings, or other items that have been modified by humans and by historical associations with materials with known dates (coins and written history).

Instead, other methods are used to work out a fossil’s age.
