Prehistoric cooking versus accurate palaeotemperature records in shell midden constituents

Abstract The reconstruction of pre-depositional cooking treatments used by prehistoric coastal populations for processing aquatic faunal resources is often difficult in archaeological shell midden assemblages. Besides limiting our knowledge of various social, cultural, economic and technological asp...
