Identification of animal pens offers relevant information as to livestock practices in late prehistoric societies. To date, livestock pens have been identified particularly in caves thanks to the recognition of fumier deposits. However, that is more complex in open-air settlements because dung degrades more rapidly and macroscopic features are not often visible. In spite of that, these features have been recognised by microscopic analyses (e.g. soil chemical analyses, presence of parasites and spherulites) or by indirect indicators such as polished walls produced by recurrent rubbing by animals. This paper proposes the use of Bone Surface Modifications (BSM) as a possible indicator to identify animal pens in open-air settlements. Mechanical bone modifications resulting from either trampling or gnawing by pigs and by domestic herbivores are the main indicators. The current findings are gleaned from the faunal assemblage of the Iron Age settlement of El Turó de la Font de la Canya (Barcelona, Spain).

骨骼表面修饰可以帮助识别家畜围栏吗？ElTuróde la Font de la Canya（西班牙巴塞罗那）铁器时代的定居点

动物笔的识别为史前晚期的牲畜活动提供了相关信息。迄今为止，由于发现了烟熏沉积物，因此特别在洞穴中发现了牲畜圈。但是，在露天定居点，情况更加复杂，因为粪便降解得更快，而且宏观特征并不经常可见。尽管如此，这些特征已通过显微镜分析（例如土壤化学分析，寄生虫和球晶的存在）或间接指标（例如动物反复摩擦产生的抛光墙）得到了认可。本文提出了使用骨表面修饰（BSM）作为在露天定居点识别动物围栏的一种可能指标。主要指标是猪和家畜食草动物践踏或食所引起的机械性骨骼改变。目前的发现是从ElTuróde la Font de la Canya（西班牙巴塞罗那）铁器时代定居点的动物群中收集的。
