Dating in Archaeology
Dating in archaeology is the process of assigning a chronological value to an event in the past. Philosophers differ on how an event is defined, but for cultural history, it can be taken as a change in some entity: the addition, subtraction, or transformation of parts. Events can be considered at two scales. At the scale of individual object, the event is either manufacture which, e.
Taking the necessary measures to maintain employees’ safety, we continue to operate and accept samples for analysis. History, anthropology, and archaeology are three distinct but closely related bodies of knowledge that tell man of his present by virtue of his past. Historians can tell what cultures thrived in different regions and when they disintegrated. Archaeologists, on the other hand, provide proof of authenticity of a certain artifact or debunk historical or anthropological findings.
Studying the material remains of past human life and activities may not seem important or exciting to the average Joe unlike the biological sciences. It is in knowing what made past cultures cease to exist that could provide the key in making sure that history does not repeat itself. Over the years, archaeology has uncovered information about past cultures that would have been left unknown had it not been with the help of such technologies as radiocarbon dating, dendrochronology , archaeomagnetic dating, fluoride dating, luminescence dating, and obsidian hydration analysis, among others.
Radiocarbon dating has been around for more than 50 years and has revolutionized archaeology. Carbon 14 dating remains to be a powerful, dependable and widely applicable technique that is invaluable to archaeologists and other scientists. The unstable and radioactive carbon 14, called radiocarbon, is a naturally occurring isotope of the element carbon.

Archaeologists use many different techniques to determine the age of a particular artifact, site, or part of a site. Two broad categories of dating or chronometric techniques that archaeologists use are called relative and absolute dating. Stratigraphy is the oldest of the relative dating methods that archaeologists use to date things. Stratigraphy is based on the law of superposition–like a layer cake, the lowest layers must have been formed first.
In other words, artifacts found in the upper layers of a site will have been deposited more recently than those found in the lower layers.
Dating methods are the means by which archaeologists establish complement each other and provide a means of cross-checking or control.
Chronological dating , or simply dating , is the process of attributing to an object or event a date in the past, allowing such object or event to be located in a previously established chronology. This usually requires what is commonly known as a “dating method”. Several dating methods exist, depending on different criteria and techniques, and some very well known examples of disciplines using such techniques are, for example, history , archaeology , geology , paleontology , astronomy and even forensic science , since in the latter it is sometimes necessary to investigate the moment in the past during which the death of a cadaver occurred.
Other markers can help place an artifact or event in a chronology, such as nearby writings and stratigraphic markers. Dating methods are most commonly classified following two criteria: relative dating and absolute dating. Relative dating methods are unable to determine the absolute age of an object or event, but can determine the impossibility of a particular event happening before or after another event of which the absolute date is well known.
In this relative dating method, Latin terms ante quem and post quem are usually used to indicate both the most recent and the oldest possible moments when an event occurred or an artifact was left in a stratum , respectively. But this method is also useful in many other disciplines. Historians, for example, know that Shakespeare’s play Henry V was not written before because Shakespeare’s primary source for writing his play was the second edition of Raphael Holinshed ‘s Chronicles , not published until That means that the play was without fail written after in Latin, post The same inductive mechanism is applied in archaeology, geology and paleontology, by many ways.
For example, in a stratum presenting difficulties or ambiguities to absolute dating, paleopalynology can be used as a relative referent by means of the study of the pollens found in the stratum. This is admitted because of the simple reason that some botanical species, whether extinct or not, are well known as belonging to a determined position in the scale of time.

Dating methods are the means by which archaeologists establish chronology. The more dating methods we use to construct a chronology, the more likely it is that the chronology will be reliable. The most universal dating method in archaeology is a relative dating method: dating by association. At it simplest, this means recognising an artefact or structure as belonging to a known type of a particular date.
Where there is a significant number of these associations, the dating information they give us becomes more reliable – individual cases can be misleading – artefacts, for instance, may be residual belonging to an earlier period but present in a later context due to redeposition. The more associations we have, the easier it is to see such problems in the evidence, and therefore the more likely the site chronology is to be correct.
Archaeologists must depend on their experience to guide them as to the most effective use of resources in commissioning scientific dating programmes. Often, this only becomes clear at the post-excavation stage. It is always good practice therefore, to take a wide range of samples of any datable material during excavation so that there will be maximum potential for a dating programme at a subsequent stage of the work. Ideally, relative and absolute dating methods should complement each other and provide a means of cross-checking or control.
Meaning of “cross-dating” in the English dictionary
Absolute dating can be achieved through the use of historical records and through the analysis of biological and geological patterns resulting from annual climatic variations, such as tree rings dendrochronology and varve analysis. Since the physical sciences contributed a number of absolute dating techniques that have had a revolutionary effect on archaeology and geology. These techniques are based upon the measurement of radioactive processes radiocarbon; potassium-argon, uranium-lead, uranium-thorium, thorium-lead, etc.
Other techniques are occasionally useful, for example, historical or iconographic references to datable astronomical events such as solar eclipses archaeoastronomy. When archaeologists have access to the historical records of civilizations that had calendars and counted and recorded the passage of years, the actual age of the archaeological material may be ascertained—provided there is some basis for correlating our modern calendar with the ancient calendar.
With the decipherment of the Egyptian hieroglyphics, Egyptologists had access to such an absolute timescale, and the age, in calender years, of the Egyptian dynasties could be established.

The dating of remains is essential in archaeology, in order to place finds in correct relation to one another, and to understand what was present in the experience of any human being at a given time and place. Inscribed objects sometimes bear an explicit date, or preserve the name of a dated individual. In such cases, dating might seem easy. However, only a small number of objects are datable by inscriptions, and there are many specific problems with Egyptian chronology, so that even inscribed objects are rarely datable in absolute terms.
In the archaeology of part-literate societies, dating may be said to operate on two levels: the absolute exactness found in political history or ‘history event-by-event’, and the less precise or relative chronology, as found in social and economic history, where life can be seen to change with less precision over time. The contrast might also be drawn between two ‘dimensions’, the historical, and the archaeological, corresponding roughly to the short-term and long-term history envisaged by Fernand Braudel.
On the one level, events and individuals are placed in an absolute chronology: the exact years and sometimes even months and days of the events and biographies are known.

dating: Absolute 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.

Tree ring dating helps answer questions about pre-Columbian life in the As part of his study, Douglass defined the “great drought,” a year period of of tree-ring dating—and what makes it so accurate—is crossdating.
The good dates are confirmed using at least two different methods, ideally involving multiple independent labs for each method to cross-check results. Sometimes only one method is possible, reducing the confidence researchers have in the results. Kidding aside, dating a find is crucial for understanding its significance and relation to other fossils or artifacts. Methods fall into one of two categories: relative or absolute.
Before more precise absolute dating tools were possible, researchers used a variety of comparative approaches called relative dating. These methods — some of which are still used today — provide only an approximate spot within a previously established sequence: Think of it as ordering rather than dating.
