This article, on the Early Neolithic pottery from the Cabeço da Amoreira shellmidden in the Muge region of central Portugal, presents a detailed review of the evidence to date and a systematic analysis of the decorative and mineralogical characteristics of the stratified and radiocarbon-dated ceramic assemblage. A homogenous pottery manufacturing tradition seems to be present right from the beginning, including both local and non-local ceramics. The authors formulate a working hypothesis on the geographic origin of the exogenous pottery, which contributes to the discussion of the dynamics of mobility and social networks in the Neolithization of south-western Europe.
