Radiocarbon dating bone collagen

Generally monospecific planktonic samples are selected for this purpose.Contaminants: Please indicate on the submission form if there are any known contaminants which could effect the radiocarbon age.These include preservatives used in conversation such as wax, varnish, glue, or insecticides and hydrocarbons.In many cases we may be able to remove the contaminants if we know about them.Sample size If at all possible, please send only the amount required for the radiocarbon dating.

If these are not available then short-lived species should be selected if possible; identifications must be done before samples are sent for radiocarbon dating.

Lake Sediments Lakes in 'hardwater' regions may have a radiocarbon age offset from the contemporaneous terrestrial environment.

This 'freshwater reservoir effect (FRE)' can be hundreds of years.

Identifiable terrestrial plant remains (macrofossils) are therefore usually the preferred samples for radiocarbon dating lake sediments.

There is the possibility of re-worked macrofossils being deposited in the lake.
