Abstract

Rapid extension of 14C-age dating into the Last Glaciation due to a rising interest in high-resolution climate events is demanding ever greater emphasis on accurate stratigraphic placement of samples relative to events or objects to be dated. This shifts the primary responsibility for date quality from the producer of dates, who is responsible for their precision, to geological and archaeological consumers, who are responsible for their stratigraphic and calibrated accuracy. It is essential that both sides accept the partial switch of mutual roles and collaborate constructively and respect the traditional freedom of choice that marks basic research.
