Fluoride dating offers a temporal resolution capable of distinguishing between features separated by as little as 20 to 40 years.This example demonstrates that fluoride dating is unlikely to be useful at most prehistoric Maya sites because of the inconsistent taphonomy due to typically diverse mortuary practices, and it also serves as a cautionary tale for applications of this methodology in other contexts. TY - JOURT1 - Issues related to determining burial chronology by fluoride analysis of bone from the Maya archaeological site of Chau Hiix, Belize AU - Wrobel, G.PY - 2007/11Y1 - 2007/11N2 - Fluoride percentage of bone is often used to determine relative dates of burials in archaeological contexts.For instance, if we find a fossil bone below the strata 3 rock level shown above, we assume that the animal most likely lived at a time before that layer was formed.However, we must be careful to note whether or not the fossil comes from the mixed strata zone of the filled in hole..These processes result in All of these processes confuse the stratigraphic record.

In many cases, however, it is possible to reconstruct the original sequence of strata so that they can be used for relative dating.

Please remember that all dating methods, even those termed "absolute," are subject to margins of error. That is a very small amount of possible error range. Modern studies almost always use two or more methods to confirm dating work and to build confidence in the results obtained.

In the past, relative dating methods often were the only ones available to paleoanthropologists.

As a result, it was difficult to chronologically compare fossils from different parts of the world.
