Having an accurate time scale is a crucial aspect of reconstructing how anatomical and behavioral characteristics of early hominids evolved. Relative dating methods allow one to determine if an object is earlier than, later than, or contemporary with some other object. It does not, however, allow one to independently assign an accurate estimation of the age of an object as expressed in years. The most common relative dating method is stratigraphy. Other methods include fluorine dating, nitrogen dating, association with bones of extinct fauna, association with certain pollen profiles, association with geological features such as beaches, terraces and river meanders, and the establishment of cultural seriations. Cultural seriations are based on typologies, in which artifacts that are numerous across a wide variety of sites and over time, like pottery or stone tools.

Methods of absolute or chronometric dating have developed greatly over recent years, with dendrochronology and radiocarbon dating in particular being used extensively by archaeologists. While relative dating techniques such as typology and frequency seriation can be used to put objects and sites in a chronology relative to each other, we must look to other methods to provide specific calendar dates.
One such method is dendrochronology, the study of tree ring growth, and was first put to notable use by A. Douglass in the ‘s. Soon after William Libby made another pivotal discovery while examining unstable carbon isotopes- radiocarbon dating. In this essay I hope to outline the actual processes involved in both methods, compare their merits and give examples of their use in dating sites.
I shall also examine the use of dendrochronology as ‘a successful means of calibrating or correcting radiocarbon dates’ Renfrew, Bahn, Renfrew and Bahn name radiocarbon dating the ‘single most useful method of dating for the archaeologist’ Renfrew and Bahn, The element carbon is absorbed constantly by living organisms as carbon dioxide, which is taken in during respiration or photosynthesis. There are three isotopes of carbon, that is, atoms that have ‘the same atomic number, but different atomic weights’, Bowman, S.
Of the three, carbon 14 is the rarest in the atmosphere, and the only carbon isotope that is radioactively unstable.
What Is Chronometric Dating?
Since its development by Willard Libby in the s, radiocarbon 14C dating has become one of the most essential tools in archaeology. Radiocarbon dating was the first chronometric technique widely available to archaeologists and was especially useful because it allowed researchers to directly date the panoply of organic remains often found in archaeological sites including artifacts made from bone, shell, wood, and other carbon based materials.
In contrast to relative dating techniques whereby artifacts were simply designated as “older” or “younger” than other cultural remains based on the presence of fossils or stratigraphic position, 14C dating provided an easy and increasingly accessible way for archaeologists to construct chronologies of human behavior and examine temporal changes through time at a finer scale than what had previously been possible. The application of Accelerator Mass Spectrometry AMS for radiocarbon dating in the late s was also a major achievement.
Most of the chronometric dating methods in use today are radiometric. That is to say, they are based on knowledge of the rate at which certain radioactive isotopes within dating samples decay or the rate of other cumulative changes in atoms resulting from radioactivity. Isotopes are specific forms of elements. The various isotopes of the same element differ in terms of atomic mass but have the same atomic number.
In other words, they differ in the number of neutrons in their nuclei but have the same number of protons. The spontaneous decay of radioactive elements occurs at different rates, depending on the specific isotope.

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.
If we next few examples of years old an eroded surface of three methods of After 11, techniques used and little meaning, absolute chronometric dating.
Ever since The Enlightenment, and possibly even before that, researchers have attempted to understand the chronology of the world around us, to figure out precisely when each stage in our geological, biological and cultural evolution took place. Even when the only science we had to go on was religious literature and the western world believed the world was created in BC 1 , scholars tried to figure out when each biblical event took place, to define a chronology from savagery to civilization, from creation to the first animal, then to the emergence of the first people.
The pre-enlightenment understanding of our geological and cultural history may now be proven wrong and subject to ridicule, but the principles of defining our place in time in the cosmos underpin many sciences. As technology advances, so do our methods, accuracy and tools for discovering what we want to learn about the past.
All dating methods today can be grouped into one of two categories: absolute dating , and relative dating. The former gives a numeric age for example, this artefact is years old ; the latter provides a date based on relationships to other elements for example, this geological layer formed before this other one. Both methods are vital to piecing together events of the past from the recent back to a time before humans and even before complex life and sometimes, researchers will combine both methods to come up with a date.
Some of the methods covered here are tried and tested, representing early methods of examining past geological, geographical, anthropological and archaeological processes. Most are multidisciplinary, but some are limited, due to their nature, to a single discipline. No system is completely failsafe and no method completely correct, but with the right application, they can and have aided researchers piece together the past and solve some of their discipline’s most complex problems.
Any scientific discipline for which chronology is important may utilize these dating methods. They may tell us many things including age, but also its place in a sequence of processes.
