Archaeologists use more scientific methods also.
Radiocarbon dating is a technique which makes it possible to date organic remains and the archaeological deposits they come from. Some artifacts made from wood can be dated using a relatively simple method called tree-ring dating. Tree-ring dating is a method that is less difficult to understand. Bones can be dated using a number of methods, most of which are highly complicated scientific techniques. The age of bones from long, long ago can sometimes be determined by dating not the bone material itself, but the rock in which it is found.
