However, as with any dating technique there are limits to the kinds of things that can be satisfactorily dated, levels of precision and accuracy, age range constraints, and different levels of susceptibility to contamination.
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.
Archaeologists now have new tools for studying the development of medieval villages and the transformation of the historical landscapes surrounding them. Radiocarbon dating is a key tool archaeologists use to determine the age of plants and objects made with organic material.
But new research shows that commonly accepted radiocarbon dating standards ...
They have the same ratio of carbon-14 to carbon-12 as the atmosphere, and this same ratio is then carried up the food chain all the way to apex predators, like sharks.
