Archaeologists have access to various techniques for dating archaeological sites or the objects found on those sites.
Relative dating is the technique used to know which object or item is older in comparison to the other one. In relative dating techniques like stratigraphy and biostratigraphy are used to know which of the object is older. Relative techniques are of great help in such types of sediments.
