Radiocarbon dating artifacts

The method is still a standard for cemetery studies.

Absolute dating, the ability to attach a specific chronological date to an object or collection of objects, was a breakthrough for archaeologists.

Each tree then, contains a record of rainfall for the length of its life, expressed in density, trace element content, stable isotope composition, and intra-annual growth ring width.Seriation, on the other hand, was a stroke of genius.First used, and likely invented by archaeologist Sir William Flinders-Petrie in 1899, seriation (or sequence dating) is based on the idea that artifacts change over time.For example, JJA Worsaae used this law to prove the Three Age System.For more information on stratigraphy and how it is used in archaeology, see the Stratigraphy glossary entry.The main drawback to dendrochronology is its reliance on the existence of relatively long-lived vegetation with annual growth rings.Secondly, annual rainfall is a regional climatic event, and so tree ring dates for the southwest are of no use in other regions of the world.Without those, the archaeologists were in the dark as to the age of various societies. The use of tree ring data to determine chronological dates, dendrochronology, was first developed in the American southwest by astronomer Andrew Ellicott Douglass.In 1901, Douglass began investigating tree ring growth as an indicator of solar cycles.Dendrochronology has been extended in the American southwest to 322 BC, by adding increasingly older archaeological samples to the record.There are dendrochronological records for Europe and the Aegean, and the International Tree Ring Database has contributions from 21 different countries.
