Carbon-14 dating can be used on objects ranging from a few hundred years old to 50,000 years old.In sites where people ate fish, we might see errors in the Carbon-14 dating of clay vessels.” This is due to the fact that fish contain less of the radioactive substance Carbon 14 if they have lived in hard water.

Hard water contains high levels of calcium carbonate. However, depending on ocean water circulation, fish and other living creatures can incorporate 'older' carbonate (with less carbon-14) into their bodies.

Libby and others (University of Chicago) devised a method of estimating the age of organic material based on the decay rate of carbon-14.
