Chronology: Tools and Methods for Dating Historical and Ancient Deposits, Inclusions, and Remains

A method of establishing the age of archaeological finds or remains by comparing them with other finds or remains which sometimes have known dates. Mentioned in? References in periodicals archive? Shells were aged by the Sclerochronology Laboratory at the Pacific Biological Station using the dendrochronological technique of cross-dating. The year of death of the dead shells was determined by using the novel technique of overlapping the synchronous growth patterns of the live and dead shells.

Meaning of “cross-dating” in the English dictionary

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.

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

Archaeologists use many different techniques to determine the age of a Cross-​dating of sites, comparing geologic strata at one site with another location when sites are far too old for absolute dates to have much meaning.

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. On the other level, the exact years may not be known, but it is known that one feature is earlier or later in relation to another; this is typically the case on an excavation, where the different archaeological strata allow objects found to be placed in a relative historical framework.

For a long period in the 20th century Egyptian and Near Eastern chronology seemed to be the earliest of absolute chronologies, and imports from these areas were used to reconstruct the chronology of European prehistory. With the introduction of objective quantifiable methods such as dendrochronology and Carbon dating, over the past half century, European and North American archaeology have developed independent and more reliable chronologies, that often make it possible to date more precisely than in Egypt.

Artefacts often have a distinctive style or design, which developed over a period of time. In archaeology, the gradual changes in motifs were exploited systematically as a dating method by researchers from Montelius onwards.

View exact match. Display More Results. The basis of cross-dating is the occurrence of finds in association. The assumption is that a particular type of artifact, for example a type of sword, when found in an undated context will bear a similar date to one found in a dated context, thus enabling the whole of the undated context to be given a chronological value. The method is based on the assumption that typologies evolved at the same rate and in the same way over a wide area or alternatively on assumptions of diffusion.
