Although not as well known as stratigraphic excavation, two other methods of relative dating have figured important in Americanist archaeology: seriation and the use of index fossils.
The latter (like stratigraphic excavation) measures time discontinuously, while the former - in various guises - measures time continuously.
Rather, common practice is to categorize them under the heading 'stratigraphic excavation'.
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.
The three-age system devised by the Danish archaeologist Christian Thomsen in the 1830s made use of technological criteria.
With the decipherment of the Egyptian hieroglyphics, Egyptologists had access to such an absolute timescale, and the age, in calender years, of the Egyptian dynasties could be established.Superposition and Stratigraphy: Measuring Time Discontinuously -- 6.
