The aim of this study is to provide a regional review and update our knowledge of molluscan records from Late Quaternary (12.2-0.4 ka AP) archaeological sites of the Pampean region. Comparisons with molluscs from the modern littoral, Holocene beach ridges and estuarine sediments are made, allowing a synthesis of the main taxa recovered and reinterpretations of the probable past human uses. Overall, the biological and archaeological data gathered reinforce the conclusion that most taxa living far from the intertidal zone were not linked to subsistence of Pampean hunter-gatherers. However, sporadic consumption cannot be discarded considering the sea-level changes during the Holocene. Other uses like ornamentation, containers, tools or symbolic meaning can be assigned to marine molluscs which were probably collected as dead shells from the fossil deposits or from the contemporary beach. Selection of the shells by humans related mainly to shell size, shape and colour, and not to their nutritional value.
