There are two techniques for dating in archaeological sites: relative and absolute dating.
Relative dating stems from the idea that something is younger or older relative to something else.

Inscriptions, distinctive markings, and historical documents can all offer clues to an artifact's age.
In a stratigraphical context objects closer to the surface are more recent in time relative to items deeper in the ground.
Although relative dating can work well in certain areas, several problems arise.
Beta Analytic uses Accelerator Mass Spectrometry (AMS) technology, which gives the most advanced precision and accuracy for carbon-14 measurements.
The lab is based in Miami, Florida, and is the world leader in carbon-14 analyses since 1979.
Most carbon atoms have six protons and six neutrons in their nuclei and are called carbon 12. But a tiny percentage of carbon is made of carbon 14, or radiocarbon, which has six protons and eight neutrons and is not stable: half of any sample of it decays into other atoms after 5,700 years.The Greeks consider the first Olympic Games as the beginning or 776 BC.The Muslims count the Prophet’s departure from Mecca, or the Hegira, as their beginning at AD 662.Aside from radiocarbon dating, ISO/IEC 17005-accredited Beta Analytic also provides biobased/renewable carbon content testing to manufacturers, product distributors, and researchers worldwide for biobased products, biofuels, waste-derived fuels and their combustion emissions (CO2 gas).The lab also uses Carbon-14 analysis for natural product source testing on materials such as flavors, fragrances, essential oils, cosmetics and supplements to identify petrochemicals.So by measuring carbon 14 levels in an organism that died long ago, researchers can figure out when it died.
