The researchers conducted an analysis of the nitrogen and carbon isotopes bound to the tooth enamel of 43 fossilized teeth, all of which had been found in South Africa's Sterkfontein caves.

The weighted mean mass of chlorine is 35.5. The relative atomic mass of an element is a weighted mean mass of the isotopes of an element compared with that of the 12 C isotope, which has a mass of ...
