Seriation, Stratigraphy, and Index Fossils: The Backbone of Archaeological Dating

Seriation, Stratigraphy, and Index Fossils: The Backbone of Archaeological Dating

In archaeology , seriation is a relative dating method in which assemblages or artifacts from numerous sites in the same culture are placed in chronological order. Where absolute dating methods, such as carbon dating , cannot be applied, archaeologists have to use relative dating methods to date archaeological finds and features. Seriation is a standard method of dating in archaeology. It can be used to date stone tools, pottery fragments, and other artifacts. In Europe, it has been used frequently to reconstruct the chronological sequence of graves in a cemetery e. Two different variants of seriation have been applied: contextual seriation and frequency seriation Renfrew and Bahn , pp. Whereas contextual seriation is based on the presence or absence of a design style , frequency seriation relies on measuring the proportional abundance or frequency of a design style.

This relative dating method, based on shared typological features, enabled Sir Flinders Petrie to establish the temporal order of a large number of Egyptian graves. It is based on the idea that an artifact type first steadily grows in popularity and then steadily declines. The technique shows how these items have changed over time and it is a way to establish chronology. Archaeological material, such as assemblages of pottery or the grave goods deposited with burials, are arranged into chronological order.

The types that comprise the assemblages to be ordered in this way must be from the same archaeological tradition, and from a single region or locality. Once the variations in a particular object have been classified by typology, it can often be shown that they fall into a developmental series, sometimes in a single line, sometimes in branching lines more as in a family tree.

The order produced is theoretically chronological, but will need archaeological assessment. Outside evidence, such as dating of two or more stages in the development, may be needed to determine which is the first and which the last member of the series. A seriation technique, called sequence dating, based on shared typological features, enabled Sir Flinders Petrie to establish the temporal order of a large number of Egyptian graves.

He established the archaeological sequence of ceramic typology, seriation, and stratigraphy of coastal Peru. Ford argued that archaeological types were imposed on data by the classifier.

For those researchers working in the field of human history, the archaeology of events principles a major element of reflection. Archaeologists have access to dating techniques for dating archaeological sites or the objects found on those sites. There are two main categories of dating methods in archaeology : archaeology or relative dating and archaeology 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 principles date is found. This approach helps to order events chronologically but it does not provide the absolute age of an object expressed in years. Relative dating includes different techniques, but the most commonly used are techniques stratigraphy analysis and typology.

On the other hand, absolute methods includes all methods that provide figures about the real archaeology age of archaeological objects or occupations. These methods usually analyze physicochemical transformation phenomena methods rate are known or and archaeology estimated relatively well. This is the only type of techniques that can help clarifying the actual age of an object. Absolute techniques methods mainly include radiocarbon dating, dendrochronology and thermoluminescence.

Stratigraphy Inspired by geology , stratigraphy uses the principle of the superposition of strata which suggests that, in a archaeology of undisturbed SOILS , the upper horizons are newer than the lower ones. Generally, each stratum is isolated in a separate chronological unit that incorporates artifacts.

However, even a casual perusal of the large body of literature that arose during the first half of the twentieth century reveals a battery of clever methods used to determine the relative ages of archaeological phenomena, often with considerable precision. Stratigraphic excavation is perhaps the best known of the various relative-dating methods used by prehistorians. Although there are several techniques of using artifacts from superposed strata to measure time, these are rarely if ever differentiated.

This text distinguishes among the several techniques and argues that stratigraphic excavation tends to result in discontinuous measures of time — a point little appreciated by modern archaeologists.

Until the 20th century, with its seriation developments, only relative dates could be determined with any confidence. Since the turn of the century, several methods to measure elapsed time have been discovered. The first and simplest re-design of absolute dating is using objects with dates inscribed on them, such as coins, or objects associated with historical events or documents.

For example, since each Roman emperor had his own face stamped on coins during his realm, and dates for emperor’s realms are known introduction historical records, the date a coin was minted may be discerned by identifying the emperor depicted. Many of the first efforts of archaeology grew out of historical documents–for example, Schliemann looked for Homer’s Troy , and Layard went after the Biblical Ninevah–and within the context of a particular site, an object clearly associated with the site and stamped with a date or introduction identifying clue was perfectly useful.

But there are certainly drawbacks. Outside of the context of a single site or society, a coin’s date is useless.

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. If archaeologists know how pottery styles, glazes, and techniques have changed over time they can date sites based on the ratio of different kinds of pottery. This also works with stone tools which are found abundantly at different sites and across long periods of time.

Stratigraphic dating is based on the principle of depositional superposition of layers of sediments called strata. This principle presumes that the oldest layer of a stratigraphic sequence will be on the bottom and the most recent, or youngest, will be on the top.
