The Rompecráneo is a special kind of lithic artifact which was, presumably, involved in the capture of pinnipeds carried out along the Patagonian coast of Argentina during prehistoric times. Recent papers had offered some information about their morphology but up to now they are poorly studied. In order to offset this situation in a previous work we addressed their role in hunting technics developed at the archaeological locality of Punta Entrada (Santa Cruz, Argentina). This allowed us to propose that rompecráneos were used in combination with spears when hunting on the coast. With the aim of expanding this information, here we present an image gallery of some rompecráneos recovered there. Two of these pieces share a similar morphology but were made of different lithic raw materials. The other one has the appearance of a bola stone but its weight is higher than other bola stones in Patagonia. That is why it is considered a different kind of artifact. The importance of studying these kinds of artifacts is that they have the potential of providing information about the way people interacted with the different resources (biotic and abiotic) in the past so that a better understanding of human behavior can be developed.   Gallery Figure 1.

在海岸狩猎：Rompecráneos 的图片库

Rompecráneo 是一种特殊的石器文物，据推测，它与史前时期在阿根廷巴塔哥尼亚海岸捕获鳍足类动物有关。最近的论文提供了一些关于它们形态的信息，但到目前为止，它们的研究很少。为了在之前的工作中抵消这种情况，我们讨论了他们在 Punta Entrada（阿根廷圣克鲁斯）考古地点开发的狩猎技术中的作用。这使我们能够提出在海岸狩猎时将 rompecráneos 与长矛结合使用。为了扩展这些信息，我们在这里展示了在那里发现的一些 rompecráneos 的图片库。其中两件具有相似的形态，但由不同的石块原材料制成。另一颗具有波拉石的外观，但重量比巴塔哥尼亚的其他波拉石高。这就是为什么它被认为是一种不同的人工制品。研究这类人工制品的重要性在于，它们有可能提供有关人们过去与不同资源（生物和非生物）交互方式的信息，以便更好地了解人类行为。图库 图 1.
