10. Dating artefacts Try to find out how old the object is A number of ways: 1.Stratigraphy – The position of the object in the soil – the deeper it is the older it is 2.Carbon Dating – all living things (plants and animals) contain carbon dioxide – after death the carbon leaks out – by measuring how much carbon is left we can discover how long ago it died 3.Dendrocronology – Can only be used to date wooden objects – each year a tree grows a new ring – age of the wood = number of rings
