There are also cases when the association between the sample and the deposit is not apparent or easily understood.
Great care must be exercised when linking an event with the context and the context with the sample to be processed by radiocarbon dating.
Radiocarbon dating results are reported in uncalibrated years BP (Before Present), where BP is defined as AD 1950.
Calibration is then done to convert BP years into calendar years.
This information is then related to true historical dates.
Anthropologists can describe a people’s physical character, culture, and environmental and social relations.
Date of a sample pre-dates the context it is found.
Some samples, like wood, already ceased interacting with the biosphere and have an apparent age at death and linking them to the age of the deposits around the sample would not be wholly accurate.
But archaeology’s aim to understand mankind is a noble endeavor that goes beyond uncovering buried treasures, gathering information, and dating events.
It is in knowing what made past cultures cease to exist that could provide the key in making sure that history does not repeat itself.
When a living thing dies, it stops interacting with the biosphere, and the carbon 14 in it remains unaffected by the biosphere but will naturally undergo decay.
