The question of cognitive complexity in early Homo sapiens in North Africa is intimately tied to the emergence of the Aterian culture (~145 ka). One of the diagnostic indicators of cognitive complexity is the presence of specialised bone tools, however significant uncertainty remains over the manufacture and use of these artefacts within the Aterian techno-complex. In this paper we report on a bone artefact from Aterian Middle Stone Age (MSA) deposits in Dar es-Soltan 1 cave on the Atlantic coast of Morocco. It comes from a layer that can be securely dated to ~90 ka. The typological characteristics of this tool, which suggest its manufacture and use as a bone knife, are comparatively similar to other bone artefacts from dated Aterian levels at the nearby site of El Mnasra and significantly different from any other African MSA bone technology. The new find from Dar es-Soltan 1 cave combined with those from El Mnasra suggest the development of a bone technology unique to the Aterian.
北非早期智人认知复杂性的问题与阿替林文化的出现（约 145 千年前）密切相关。认知复杂性的一个诊断指标是专门的骨工具的存在，然而，在阿替林技术复合体中，这些人工制品的制造和使用仍然存在很大的不确定性。在本文中，我们报告了来自摩洛哥大西洋海岸达累斯萨拉姆 1 号洞穴的阿替林中石器时代（MSA）沉积物中的一件骨制品。它来自一个可以安全追溯到约 90 千年前的层位。该工具的类型特征表明它是作为骨刀制造和使用的，与来自附近 El Mnasra 地点的有日期的阿替林层位的其他骨制品相比具有相似性，而与任何其他非洲 MSA 骨技术相比则有明显的不同。来自达累斯萨拉姆 1 号洞穴的新发现与来自 El Mnasra 的发现一起表明，阿替林发展了一种独特的骨技术。
