最近的研究表明，海洋食物在西欧一些中石器时代晚期（公元前5000-4000卡路里）人群饮食中的重要性，但对这些资源在中石器时代早期的作用知之甚少。通过对波特兰岛Culverwell贝壳丘的海洋软体动物组合的分析，发现三种优势种的绝对丰度以及Monodonta lineata （da Costa）的平均贝壳大小和年龄级频率通过贝壳丘发生了变化。这些变化是由于人类对这些软体动物种群的觅食影响造成的，并且在中石器时代早期（公元前6000-5200cal），岩岸潮间带软体动物被密集而频繁地（可能每年）利用。
Recent research has indicated the importance of marine foods in the diet of some late Mesolithic (c.5000-4000cal bc) populations in western Europe, but little is known of the role of such resources in the earlier Mesolithic. Analysis of assemblages of marine molluscs from the shell midden of Culverwell, Isle of Portland, showed changes in the absolute abundance of the three dominant species, as well as changes of mean shell size and age-class frequencies in the species Monodonta lineata (da Costa), through the midden. It is suggested that these changes result from the impact of human foraging on the populations of these molluscs, and that rocky-shore intertidal molluscs were exploited intensively and frequently (possibly annually) from the site in the earlier Mesolithic (c.6000-5200cal bc).
