In recent decades, investigations in the southern Iberian Peninsula have increased our understanding of the socio-economic impact of the spread of the Neolithic in southwestern Europe, including changes in marine resources exploitation. Nevertheless, considerable uncertainty still exists around the seasonality of such subsistence systems and the putative role of marine fish and shellfish to the evolving agro-pastoral economies. Earlier studies on the European Atlantic coast (including Iberia) have shown that the stable oxygen isotope (δ¹⁸O) values from the topshell Phorcus lineatus (da Costa, 1778) can be reliably used to derive seasonal sea surface temperatures (SST) during its lifespan. This information can be used by archaeologists to estimate the seasonality of mollusc collection in the past, and to shed light into settlement and subsistence patterns. This paper presents the results of a stable isotope study on archaeological shells of P. lineatus recovered from the Neolithic settlement of Campo de Hockey (Cádiz, Spain). We analysed shells from both funerary and residential contexts and found that P. lineatus was consumed year-round, but with a stronger preference during winter. Our results therefore contribute to advance our understanding of the role of coastal environments in early farming societies of southwestern Europe.

近几十年来，对伊比利亚半岛南部的调查加深了我们对新石器时代在欧洲西南部传播所造成的社会经济影响的了解，包括海洋资源开发的变化。然而，这种生存系统的季节性以及海洋鱼类和贝类对不断发展的农牧业经济的假定作用仍然存在相当大的不确定性。早期对欧洲大西洋沿岸（包括伊比利亚）的研究表明，来自顶壳Phorcus lineatus （da Costa，1778）的稳定氧同位素（δ ¹⁸ O）值可以可靠地用于推导其期间的季节性海面温度（SST）。寿命。考古学家可以利用这些信息来估计过去软体动物采集的季节性，并揭示定居和生存模式。本文介绍了对从 Campo de Hockey（西班牙加的斯）新石器时代定居点发现的P. lineatus考古贝壳进行稳定同位素研究的结果。我们分析了葬礼和住宅环境中的贝壳，发现线纹虾全年都被食用，但在冬季更受欢迎。因此，我们的研究结果有助于加深我们对沿海环境在欧洲西南部早期农业社会中的作用的理解。
