# Ice Age Hunter-Gatherers Reached Italy Earlier Than Previously Estimated New evidence from Riparo Mochi suggests Noaillian migration occurred 2,000 years earlier than expected. - **Source:** [All Articles | Discover Magazine](https://www.discovermagazine.com/rss/all) - **Published:** 2026-11-11 - **Topic:** [science](https://brifing.si/c/science) - **Original article:** - **On Brifing:** https://brifing.si/s/346a224b-be57-4f7d-b86c-095566cac089 ## Revised Migration Timeline Archaeologists have discovered that the Noaillian hunter-gatherer culture arrived at the Riparo Mochi site in Italy approximately 30,000 years ago. This finding shifts the previously accepted timeline by 2,000 years, suggesting these ancient humans reached the region much earlier than researchers had originally estimated during earlier excavation efforts at the site. ## Radiocarbon Dating Methodology To determine the site's true age, researchers utilized radiocarbon dating on marine shells discovered near an ancient hearth. This scientific analysis confirmed that the occupation layer dates back to between 30,000 and 30,700 years ago. These results resolve previous discrepancies between the Riparo Mochi data and other sites located in southern Italy. ## The Noailles Burin Tool The Noaillian culture is defined by the use of the Noailles burin, a specialized stone tool. Often compared to a modern pocket knife, these tools featured small, sharp edges suitable for drilling, scraping, and engraving. Evidence suggests they were essential for processing animal hides and tissues during the harsh Ice Age climate. ## Climatic Migration Drivers The migration from northeastern Spain toward Italy was likely triggered by the onset of severe cold spells across Europe. As temperatures began to plummet 29,000 years ago, these hunter-gatherers moved eastward. They sought warmer refuges in southern Italy, occupying territories that were previously uninhabited or only sporadically visited by other human groups. ## Seasonal Camp Dynamics Excavations conducted between 2019 and 2022 at the Balzi Rossi caves revealed a hearth surrounded by animal remains and stone tools. Researchers believe Riparo Mochi served as a seasonal hunting camp. This location allowed the group to efficiently process meat and hides while navigating the coastal corridors along the Mediterranean Sea. ## Broader Cultural Context The Noaillian culture represents a specific subset of the wider Gravettian culture, which spanned from 33,000 to 21,000 years ago. By studying these groups, scientists gain insight into how humans survived the Last Glacial Maximum. Their rapid expansion across Europe demonstrates a high level of adaptability to changing environmental conditions and resource availability. ## Archaeological Site Significance Riparo Mochi, situated near the French-Italian border in Ventimiglia, remains a critical site for understanding human movement. The presence of Noailles burins at this location confirms the cultural link between Spanish and Italian populations. This site provides a tangible record of how ancient humans navigated the landscape during the late Pleistocene era. ## Future Research Implications This discovery forces a reevaluation of how quickly prehistoric cultures expanded across the Mediterranean basin. By establishing a more accurate chronology, scientists can better map the movement of early humans as they responded to climate shifts. Future studies will likely focus on how these groups maintained cultural continuity across such vast distances. ## Sources covering this story - https://www.discovermagazine.com/shells-and-stone-tools-suggest-ice-age-hunter-gatherers-rapidly-reached-italy-much-earlier-than-previously-thought-49934 — --- _Summary written by Brifing from the original reporting.
