Abstract:Rationale: For years, archaeologists, climatologists, and ecologists have used stable oxygen isotope values (δ 13 C, δ 18 O) in fish otoliths from archaeological sites to reconstruct the habitats, paleo-temperature, and seasonality of the fish captures.Otoliths from archaeological sites might have been heated when ancient people cooked the fish for food. Therefore, there are debates as to whether the cooking behaviors would cause further isotopic fractionations of the carbonate in the otoliths.Methods: In this… Show more
