Archaeologists have uncovered what is believed to be the oldest shell jewelry workshop in Europe at the Paleolithic site of La Roche-à-Pierrot in Saint-Césaire, southwestern France.
The site, dating back at least 42,000 years, contains pierced shells and colored pigments, offering rare insight into early symbolic behavior. This shell jewelry workshop in France adds new depth to ongoing research into the cultural practices of prehistoric humans.
The discovery, detailed in the Proceedings of the National Academy of Sciences, was made by a team of researchers from the French National Centre for Scientific Research (CNRS), the University of Bordeaux, the Ministry of Culture, and the University of Toulouse-Jean Jaurès.
Their findings suggest that the site served as a production center for personal ornaments during the Châtelperronian period, a cultural phase marking the transition between Neanderthals and Homo sapiens in Europe.
Evidence of symbolic expression and long-distance mobility
Several of the shells had no signs of wear on their perforations, while others had yet to be pierced, indicating they were in the process of being transformed into jewelry. Traces of red and yellow pigments were also found nearby.
The research team found that the shells originated from the Atlantic coast, nearly 100 kilometers (62 miles) away at the time, and the pigments were sourced from more than 40 kilometers (25 miles) inland. This evidence supports the idea that prehistoric groups either traveled long distances or participated in early forms of trade.
The site also yielded typical Neanderthal tools and the remains of hunted animals such as bison and horses, suggesting a complex and varied human presence.
Archaeologist Marie Soressi, one of the lead researchers, noted that the findings help demonstrate the symbolic and technological sophistication of the Châtelperronian people, who may have been influenced by or part of early Homo sapiens populations entering the region.
Châtelperronian culture under scientific debate
Researchers continue to debate whether Neanderthals or early modern humans made the artifacts.
The Châtelperronian culture, present in parts of France and northern Spain between 55,000 and 42,000 years ago, is recognized as one of the earliest Upper Paleolithic industries in Eurasia.
The Saint-Césaire site has been under study since 1976 and remains a key location for understanding the interactions between Neanderthals and Homo sapiens.
Continued excavation and analysis, including the re-examination of earlier finds using updated methods, have turned the site into a critical reference point for exploring prehistoric mobility, cultural exchange, and identity.
