DATING METHODS JOSEPH W. MICHELS. Department of Anthropology, The Pennsylvania State University. University Park, Pennsylvania.

By the early twentieth century there was a growing need within palaeoanthropology and prehistoric archaeology to find a way of dating fossils and artefacts in order to know the age of specific specimens, but more importantly to establish an absolute chronology for human prehistory. The radiocarbon and potassium-argon dating methods revolutionized palaeoanthropology during the last half of the twentieth century. However, prior to the invention of these methods there were attempts to devise chemical means of dating fossil bone.

The invention of the fluorine dating method marked a significant advance in the quest for absolute dating in palaeoanthropology, but it also highlights interesting problems and issues relating to the ability of palaeoanthropologists and chemists to bring together different skills and bodies of knowledge in order successfully to develop and apply the fluorine dating method.

Dating in Archaeology

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.

Dating methods in historical archaeology differ little from the methods of archaeology in general. Both absolute and relative dating approaches are employed. However, historical archaeology has tended to de-emphasize archaeometric analyses because of the availability of a documentary record. Absolute dating methods that rely on specialized laboratory analyses such as dendrochronology, radiocarbon, and luminescence measurements are available to historical archaeologists. Radiocarbon dating generally is not reliable for samples postdating c.

Artifact : an object formed by humans. Carbon : a chemical element important to life on Earth; it is one of the most abundant elements in the universe. Carbon isotopes : atoms of carbon that have different numbers of neutrons; isotopes are sometimes used to determine the diet of mammal herbivores by analyzing the carbon in fossilized teeth. DNA : deoxyribose nuleic acid, which carries genetic information; it is composed of nucleotides.

Isotope : a variation of an element that differs in the number of parts it possesses, more specifically the number of subatomic particles called neutrons. Radiocarbon dating : a technique that measures the age of an object containing carbon by measuring the decay of the radioactive isotope carbon

Chronological dating

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.

In archaeology, dating techniques fall into two broad categories: chronometric (​sometimes called “absolute”) and relative. Chronometric dating.

FutureLearn accepts no liability for any loss or damage arising as a result of use or reliance on this information. There is no single ideal method of dating that can produce accurate results for every kind of sample, in every context, for every chronology.

Each method of dating has constraints around its use and effectiveness. Not all methods are well-suited for each situation — and sometimes it is just not possible to use a particular dating method. To gain a reliable date from bone using the radiocarbon, or C dating method, we need to be able to extract the protein from it — collagen and gelatin.

The challenge here is that the amount of protein remaining in the bone decreases with age, to the point where there may not be much left in the sample at all. Added to this is the risk of contamination of the sample. Contamination may have occurred during the burial of the bones, or as the result of carbonates that have washed into the sample from the soils. Even poor handling during collecting and packaging of the sample can create cross-contamination between samples or add modern carbon to the sample.

Adding modern carbon through contamination reduces the apparent age of the sample. For C dating, the size of the sample is also important. Larger samples are desirable, as the dating process causes some loss of material.

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.

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. One of the first and most basic scientific dating methods is also one of the easiest to understand.

Paleontologists still commonly use biostratigraphy to date fossils, often in combination with paleomagnetism and tephrochronology.
