Chinese Japanese Korean Vietnamese. The differentiation of cooked from uncooked bone, shell, and residue is sometimes possible. Temperate to cold region studies are much more common than tropical studies, and the steady cold of the ocean floor or the dry interior of bones and shells have contributed most to the accumulation of racemization dating data.
