Camelid pastoralism, agriculture, sedentism, surplus production, increasing cultural complexity, and interregional interaction during northern Chile's Late Formative period (AD 100–400) are seen in the flow of goods and people over expanses of desert. Consolidating evidence of material culture from these interactions with a bioarchaeological dimension allows us to provide details about individual lives and patterns in the Late Formative more generally. Here, we integrate a variety of skeletal, chemical, and archaeological data to explore the life and death of a small child (Calate-3N.7). By taking a multiscalar approach, we present a narrative that considers not only the varied materiality that accompanies this child but also what the child's life experience was and how this reflects and shapes our understanding of the Late Formative period in northern Chile. This evidence hints at the profound mobility of their youth. The complex mortuary context reflects numerous interactions and long-distance relationships. Ultimately, the evidence speaks to deep social relations between two coastal groups, the Atacameños and Tarapaqueños. Considering this suite of data, we can see a child whose life was spent moving through desert routes and perhaps also glimpse the construction of intercultural identity in the Formative period.

在智利北部形成后期（公元 100-400 年）期间，骆驼畜牧业、农业、定居、过剩生产、日益增加的文化复杂性和区域间互动在大片沙漠中的货物和人员流动中可见一斑。将这些相互作用中的物质文化证据与生物考古学维度相结合，使我们能够更普遍地提供有关晚期形成时期个人生活和模式的细节。在这里，我们整合了各种骨骼、化学和考古数据来探索一个小孩的生死 (Calate-3N.7)。通过采用多尺度方法，我们提出了一个叙述，不仅考虑了伴随这个孩子的各种物质性，还考虑了这个孩子是什么” 她的生活经历以及这如何反映和塑造我们对智利北部晚期形成时期的理解。这一证据暗示了他们年轻时的深刻流动性。复杂的太平间环境反映了许多互动和远距离关系。最终，证据说明了两个沿海群体 Atacameños 和 Tarapaqueños 之间深厚的社会关系。考虑到这组数据，我们可以看到一个孩子的一生是在沙漠路线中度过的，也许还可以窥见形成时期跨文化身份的构建。Atacameños 和 Tarapaqueños。考虑到这组数据，我们可以看到一个孩子的一生是在沙漠路线中度过的，也许还可以窥见形成时期跨文化身份的构建。Atacameños 和 Tarapaqueños。考虑到这组数据，我们可以看到一个孩子的一生是在沙漠路线中度过的，也许还可以窥见形成时期跨文化身份的构建。
