Balma del Gai site is a small rock shelter situated in the municipality of Moià (Barcelona, ​​ Spain) at an altitude of 760 m above sea level and 50 km from the current coastline. The levels of occupation in this context are dated between 13,442 cal BP and 9,552 cal BP, being related to the so-denominated “Epimagdalenian” and “Microlaminar Sauveterroid” complexes. The excavations have provided important mollusc samples, both terrestrial and marine, which have been studied and considered alimentary and adornment resources. In this article, we present the results of the use-wear analyses of the shell tools of Mytilus galloprovincialis Lamarck, 1819 and Glycymeris glycymeris (Linnaeus, 1758). The results of these analyses and their comparison with analytical experimentation demonstrate that some of these shells were used as tools for developing diverse productive activities related to the processing of materials of animal, mineral and vegetal origin. In this way, this research contributes to: 1) broaden the technological spectrum registered in this context and in a wider sense for Epipalaeolithic hunter-gatherers (beyond the traditional technological elements), 2) demonstrate a diversified use of the shells as adornments, food and tools in the site; an aspect of great interest especially bearing in mind the distance from the coast.

Balma del Gai站点是一个小型岩石掩体，位于Moià（西班​​牙巴塞罗那）的自治市中，海拔760 m，距当前海岸线50 km。在这种情况下，职业水平在13,442 cal BP至9,552 cal BP之间，与所谓的“表皮达林岩”和“微层类蜥蜴类”复合物有关。该发掘提供了重要的陆生和海洋软体动物样本，这些样本已经过研究并被视为饮食和装饰资源。在本文中，我们介绍了Mytilus galloprovincialis Lamarck（1819年）和Glycymeris glycymeris外壳工具的使用磨损分析结果。（Linnaeus，1758年）。这些分析的结果以及它们与分析实验的比较表明，其中一些贝壳被用作开发与动物，矿物和植物来源的材料加工有关的各种生产活动的工具。通过这种方式，这项研究有助于：1）拓宽在此背景下注册的技术范围，并在更广泛的意义上为表壳石器时代的狩猎者-采集者（除传统技术元素外），2）展示了将贝壳作为装饰品，食品的多种用途网站中的工具；一个令人非常感兴趣的方面，尤其要牢记与海岸的距离。
