Ancient Children Reveal Clues to Atlantic Coastal Migration in Patagonia

The discovery of two ancient children’s remains near Camarones, Patagonia, is providing new evidence supporting the theory of an Atlantic coastal migration route during the initial peopling of South America. Dated to over 10,000 years ago, the site is unique for its preservation and the insights it offers into the lives of these early inhabitants.

Unlike inland sites, the Atlantic coast has yielded few early human remains, largely because rising sea levels have submerged potential archaeological sites. However, the geology of Camarones – featuring rocky outcrops that resisted coastal erosion – preserved this burial ground.

The children’s remains reveal a mixed diet of marine and terrestrial resources, indicating a deep understanding of the coastal environment. One child, in particular, showed a high consumption of seafood.

Further analysis revealed a unique anatomical trait in the younger child – triangular-shaped incisors – previously unrecorded in Patagonian hunter-gatherer populations. The presence of 50 meticulously crafted bone beads, likely forming a necklace, and the use of locally sourced red ochre, demonstrate a sophisticated knowledge of the landscape and its resources.

This discovery, coupled with the nearby Baño Nuevo 1 site (dated similarly but with a terrestrial diet), suggests interconnectedness between groups inhabiting the Patagonian region. While not definitively proving the Atlantic route, the Camarones site offers a crucial piece of evidence, indicating that people did indeed move along the Atlantic coast during the early peopling of South America. The site remains undisturbed, a silent testament to a landscape that continues to hold the memories of those who lived there over 11,000 years ago.
