Here, we describe eight bone artifacts recovered from Pleistocene and Holocene contexts at Riwi, a cave site located in Mimbi country of the south-central Kimberley. These artifacts reflect a range of activities occurring at the site—including the manufacture of plant-fiber items, the processing of spinifex resin, and fish or bird hunting. As the oldest four artifacts were found within the Pleistocene deposit and therefore date to older than 35,000 cal. BP, these tools represent some of the most ancient bone technologies thus far identified in northern Australia. Such rare finds are helping to rewrite stories surrounding the innovation and use of osseous technologies on the Australian continent.

来自金伯利中南部 Riwi Cave 的骨制品：重新评估澳大利亚北部骨质制品的时间和作用

在这里，我们描述了从位于金伯利中南部 Mimbi 国家的洞穴遗址 Riwi 的更新世和全新世环境中恢复的八件骨制品。这些文物反映了现场发生的一系列活动——包括植物纤维制品的制造、刺槐树脂的加工以及鱼类或鸟类狩猎。由于在更新世矿床中发现了最古老的四件文物，因此可以追溯到 35,000 卡路里以上。BP，这些工具代表了迄今为止在澳大利亚北部发现的一些最古老的骨骼技术。如此罕见的发现有助于改写澳大利亚大陆有关骨骼技术创新和使用的故事。
