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.

Dating in Archaeology | The Canadian Encyclopedia

Human prehistory is the period between the use of the first stone tools c. The earliest writing systems appeared c. The end of prehistory therefore came at very different dates in different places, and the term is less often used in discussing societies where prehistory ended relatively recently. Sumer in Mesopotamia , the Indus valley civilization , and ancient Egypt were the first civilizations to develop their own scripts and to keep historical records; this took place already during the early Bronze Age. Neighboring civilizations were the first to follow. Most other civilizations reached the end of prehistory during the Iron Age. The three-age system of division of prehistory into the Stone Age , followed by the Bronze Age and Iron Age, remains in use for much of Eurasia and North Africa , but is not generally used in those parts of the world where the working of hard metals arrived abruptly with contact with Eurasian cultures , such as the Americas , Oceania , Australasia and much of Sub-Saharan Africa.

Dating in Archaeology

This task of interpretation has five main aspects. The first concern is the accurate and exact description of all the artifacts concerned. Classification and description are essential to all archaeological work, and, as in botany and zoology , the first requirement is a good and objective taxonomy. Second, there is a need for interpretive analysis of the material from which artifacts were made. This is something that the archaeologist himself is rarely equipped to do; he has to rely on colleagues specializing in geology , petrology analysis of rocks , and metallurgy.

The most widely known form of radiometric dating is carbon dating. This is what archaeologists use to determine the age of human-made artifacts. But carbon dating won't work on dinosaur bones. The half-life of carbon is only 5, years, so carbon dating is only effective on samples that are less than 50, years old.
