Books, clothing and food remains are all archaeological artifacts that can be carbon dated.
Carbon-based rocks, such as bitumen and tephra, can also be dated in this manner.
Continue Reading Carbon dating works by comparing the amount of carbon-14 in a sample to the amount of carbon-12.Later called Ötzi the Iceman, small samples from his body were carbon dated by scientists.The results showed that Ötzi died over 5000 years ago, sometime between 33 BC. It is found in the air in carbon dioxide molecules.Materials that originally came from living things, such as wood and natural fibres, can be dated by measuring the amount of carbon-14 they contain.For example, in 1991, two hikers discovered a mummified man, preserved for centuries in the ice on an alpine mountain.
A detailed description of radiocarbon dating is available at the Wikipedia radiocarbon dating web page.
