Dendrochronology absolute relative dating
Probably the most well known dating method is carbon-14 (C-14) dating.This method of absolute dating is based on the measurement of the radioactive decay of the C-14 atom.Voyage into Archaeology Links, articles, and other beginner's resources in archaeology, including a simulation game called "Be a Time Detective." Glossary of Archaeological Terms What is chert? For example, the arrival of sophisticated carbon-14 dating methods in the 1940s caused scientists to revise their interpretation of events in Europe in prehistoric times. Accurate dating is important for putting events and objects in sequence.
This dating method is used to date obsidian, a kind of volcanic glass.
Adding the margin of error for carbon-14 (in this case, /- 150 years), the archaeologist can give a reliable date range for the bone: 1655-1405 B. A bone found deep in the ground will generally be older than one found close to the surface, for example.
