Radiocarbon dating is especially good for determining the age of sites occupied within the last 26,000 years or so (but has the potential for sites over 50,000), can be used on carbon-based materials (organic or inorganic), and can be accurate to within ±30-50 years.

Shell may succumb to isotopic exchange if it interacts with carbon from percolating ground acids or recrystallization when shell aragonite transforms to calcite and involves the exchange of modern calcite.

The surrounding environment can also influence radiocarbon ages.

There are two sources of uncertainty in radiocarbon ages.

First, there is unavoidable imprecision in the laboratory-calculated age.
