We wouldn''t be dating the artifact – we'd be dating the rock and the rock might have formed millions of years earlier.

The method drastically reduces the quantity of datable material required.
SYNONYMS OR RELATED TERMS: amino-acid dating; aminostratigraphy; amino-acid racemization, amino acid racemization CATEGORY: technique DEFINITION: A method of absolute (chronometric) dating which is hoped to fill the gap between radiocarbon dates and potassium-argon dates.
Relative dating methods do not tell archaeologists exactly how old things are, but only how old things are relative to each other.
Acropolis - The "high point" or citadel of an ancient Greek city, like the Acropolis in Athens.(Examples of each method, respectively, are dendrochronology, carbon-14, archaeomagnetism, and the known year a city was destroyed.) Relative dating is based on stratigraphy (the tendency of younger layers to lie over older layers) and comparison of artifacts from undated sites to sites where dates are established.All dating methods have limitations and can be complicated by turbation, or mixing, of layers by human or natural actions.This method can give archaeologists an indication of the age of the artifacts in all Absolute dating methods can give an estimate of the real calendar age of an artifact or site.
There are several absolute dating methods that archaeologists can use, including radiocarbon dating and potassium argon dating.potassium) decays into argon over time, so the age of certain rocks or minerals can be discovered by measuring the amount of argon they contain.Aerial Photography - The various techniques of taking photographs of natural or cultural features from the air, using balloons, airplanes, satellites, and other sources, in order to study the features in their entirety from a top-down (bird's eye) view.
