For those researchers working in the field of human history, the chronology of events remains a major element of reflection. 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. Relative dating includes methods that rely on the analysis of comparative data or the context eg, geological, regional, cultural in which the object one wishes to date is found. This approach helps to order events chronologically but it does not provide the absolute age of an object expressed in years.

Relative dating is the science of determining the relative order of past events i. In geology, rock or superficial deposits , fossils and lithologies can be used to correlate one stratigraphic column with another. Prior to the discovery of radiometric dating in the early 20th century, which provided a means of absolute dating , archaeologists and geologists used relative dating to determine ages of materials. Though relative dating can only determine the sequential order in which a series of events occurred, not when they occurred, it remains a useful technique. Relative dating by biostratigraphy is the preferred method in paleontology and is, in some respects, more accurate.
What Is the Difference Between Relative and Absolute Age?
In archaeology , a typology is the result of the classification of things according to their physical characteristics. The products of the classification, i. Most archaeological typologies organize portable artifacts into types, but typologies of larger structures, including buildings, field monuments , fortifications or roads, are equally possible. A typology helps to manage a large mass of archaeological data.
The Archiving the Archaeologists series is an oral history project of video interviews of archaeologists near retirement or already retired. Listen to real archaeologists reflect on their careers, how and why they became archaeologists, and their contributions to the discipline on the SAA YouTube channel. The methods used by archaeologists to gather data can apply to any time period, including the recent past. One archaeologist in the U.
