Seriation, Stratigraphy, and Index Fossils 

By: Michael J. O'Brien & R. Lee Lyman

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. 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.
