Unfortunately, most absolute dating methods give slightly fuzzy dates (radiocarbon dates are usually plus or minus 40 years or more), so sometimes we can get the order more precisely by lower-tech, relative methods. Integrated with 14c dating (so-called dendro-14c-wiggle-matching), it should provide a near high-resolution chronological framework, focused initially on epi-classic sites in northwest mexico though the project is still in its initial stages.

Dendrochronology is based on the phenomenon that trees usually grow by the addition of rings dendrochronological findings played an important role in the early days of radiocarbon dating tree rings provided truly known-age material needed to check the accuracy of the carbon-14 dating method.

Dendrodk carries out research-based and commercial analysis of wood from archaeological and historic contexts through dendrochronology, timbers are precisely dated and their region of origin is identified. Dendrochronology uses the rings of trees to determine the age of the tree 'dendro' means 'tree', and 'chronology' refers to the sequence of events in.
Dendro-testing the main purpose of a dendrochronological test, is to determine when the tree used to make the soundboard of an instrument was growing a process known as cross-dating, identifies the similarities between the pattern formed by the tree-rings of a sample, and those of thousands of dated references. Studying dendrochronology dendrochronology is the study of data from tree ring growth due to the sweeping and diverse applications of this data, specialists can come from many academic disciplines.
