Please contact us to discuss your requirements. For practical purposes 14 C dating records the time of death of an organism and not the point at which it is finally entombed in sediment. I agree to receive infrequent updates with the option to unsubscribe at any time. A reservoir correction factor must therefore be applied to conventional radiocarbon dates based on the remains of marine organisms. I have samples to send. The average difference between a radiocarbon date of a terrestrial organism such as a tree and a marine shell of the same age is about radiocarbon years.
