Abstract Ground-stone objects such as stone-headed clubs (gabagab) and axes/adzes held key positions in ethnographically known social networks encompassing Torres Strait and southern central New Guinea. However, the antiquity of ground-stone artefacts in this region is poorly understood given the small number of ground-stone objects found in dated archaeological contexts. We report on the discovery of a 1,200-year-old fragment of a ground-stone implement recovered from an archaeological excavation at a Kaurareg campsite on the south coast of Muralag in southwest Torres Strait. We discuss this find relative to the dataset of dated ground-stone objects available for the region and consider implications for understanding socio-demography, identity markers, and the development of social networks in Torres Strait.

来自西南托雷斯海峡（澳大利亚东北部）的一个有1200年历史的地基物体及其对民族志已知的社交网络进行历史化的意义

摘要在包括托雷斯海峡和新几内亚中南部在内的人种学方面，已知的社交网络中，像石头石头般的棍棒（gabagab）和斧头/着迷之类的地面石头物体处于关键位置。但是，鉴于在过时的考古背景下发现的少量地面岩石物体，对该地区的古代地面岩石人工制品的了解很少。我们报告了在托雷斯海峡西南部Muralag南海岸的一个Kaurareg营地的考古发掘中发现的一个1200年历史的碎石工具碎片的发现。我们讨论了与该地区可用的过时的地面物体的数据集有关的发现，并考虑了对理解社会人口统计学，身份标记以及托雷斯海峡社交网络发展的影响。缩写：var.：variant; PNG：
