This means these pieces of wood may not give you the correct date even using dendrochronology, so it is very important to look at more than one set of tree rings.
A man called Willard F Libby pioneered it at the University of Chicago in the 50's. This is now the most widely used method of age estimation in the field of archaeology.
Archaeologists have access to various techniques for dating archaeological sites or the objects found on those sites.
There are two main categories of dating methods in archaeology: indirect or relative dating and absolute dating.
Moreover, stratigraphic dating is sometimes based on the objects that are found within the soil strata.
Indeed, some items whose exact or approximate age is known are called "diagnostic artifacts." Examples of such objects include very specific stone tools, different pottery styles, objects that belong to a specific period (eg, the historic period or the French regime), coins with a production date, or other items bearing a trademark and whose history can be traced in historical records.
