Carbon dating zooarchaeology
Curator Geoffrey Hargreaves inspects core samples from the Greenland ice sheet. The cores are vital to understanding changes in atmospheric carbon levels in the past.

Reliable estimates are possible, but with large /- factors.Archaeological specimens range in age from a few hundred to approximately six thousand years old.Collagen was extracted, its quality assessed using %C, %N and C: N, and δN values from the two laboratories.The carbon-14 method was developed by the American physicist Willard F. It has proved to be a versatile technique of dating fossils and archaeological specimens from 500 to 50,000 years old.The method is widely used by Pleistocene geologists, anthropologists, archaeologists, and investigators in related fields.
