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. At the scale of more than one object, often called an assemblage, the event is usually the deposition of those objects at a single place.
Such an event, if human caused, is often called an occupation. All events have duration. It can be trivially short for many manufactures, but it can last over several centuries for some occupations. The two scales can overlap, as for example with monumental architecture, where the manufacture might be considered as a series of Skip to main content Skip to table of contents.
Dating dinosaurs and other fossils
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
Chronology and dating methods
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.

Slideshows Videos Audio. Here of some of the well-tested methods of dating used in the study of early humans: Potassium-argon dating , Argon-argon dating , Carbon or Radiocarbon , and Uranium series. All of these methods measure the amount of radioactive decay of chemical elements; the decay occurs in a consistent manner, like a clock, over long periods of time. Thermo-luminescence , Optically stimulated luminescence , and Electron spin resonance.
All of these methods measure the amount of electrons that get absorbed and trapped inside a rock or tooth over time. Since animal species change over time, the fauna can be arranged from younger to older. At some sites, animal fossils can be dated precisely by one of these other methods. For sites that cannot be readily dated, the animal species found there can be compared to well-dated species from other sites.

Taking the necessary measures to maintain employees’ safety, we continue to operate and accept samples for analysis. Radiocarbon dating is a method that provides objective age estimates for carbon-based materials that originated from living organisms. The impact of the radiocarbon dating technique on modern man has made it one of the most significant discoveries of the 20th century.

All rights reserved. Relative techniques were developed earlier in the history of archaeology as a profession and are considered less trustworthy than absolute ones. There are several different methods. In stratigraphy , archaeologists assume that sites undergo stratification over time, leaving older layers beneath newer ones. Archaeologists use that assumption, called the law of superposition, to help determine a relative chronology for the site itself. Then, they use contextual clues and absolute dating techniques to help point to the age of the artifacts found in each layer.
Learn how archaeologists dated the earliest metal body part in Europe. Objects can be grouped based on style or frequency to help determine a chronological sequence. Relative dating has its limits. For a more precise date, archaeologists turn to a growing arsenal of absolute dating techniques. Perhaps the most famous absolute dating technique, radiocarbon dating was developed during the s and relies on chemistry to determine the ages of objects. Its inventor, Willard Libby, eventually won a Nobel Prize for his discovery.
The tibia bone of Australopithecus anamensis provided firm evidence that hominins walked upright half a million years earlier than previously thought. Thermoluminescence dating measures how many years have elapsed since the heating of a material containing a crystalline mineral.
