Archaeologists discovered butchered gomphothere bones and stone tools at Lake Tagua Tagua in Chile, dating back 13,000 years. This find confirms early hunter-gatherer activity in the region during the late Pleistocene.
Why it matters
The site provides critical evidence for understanding the timing and migration patterns of the earliest human populations in South America. It adds to the growing body of data regarding how these groups interacted with extinct megafauna.
The recovered bone and artifact assemblage dates to between 12,000 and 13,000 years ago, based on excavations conducted over the past two years. Researchers are currently analyzing sediment samples to refine the timeline of human arrival.
The players
IPHES-CERCA
This is a research institution specializing in human paleoecology and social evolution that reported the findings at the site.
The details
Excavations in the ancient lake basin revealed gomphothere bones featuring distinct human-made cut marks alongside various stone tools. These remains suggest that early inhabitants utilized the site for butchery, mirroring patterns seen at other regional locations like Arroyo Seco and Huaca Prieta.
Timeline
13,000 years ago: Humans inhabited the Lake Tagua Tagua area.
12,000 to 13,000 years ago: The period when the recovered bones and artifacts were deposited.
Past two years: The timeframe in which the archaeological excavations took place.
September 24, 2026: The IPHES-CERCA institution released their official statement.
The Big Picture
This discovery follows the historical pattern set by the Monte Verde archaeological site in establishing the presence of early humans in the Americas. It refines the existing timeline of human arrival in South America by confirming activity at a separate, geographically significant location.
The identification of these tools and butchery marks offers tangible insights into how early human populations adapted to environmental shifts and megafauna. These findings provide a clearer window into the prehistoric development of the South American continent.
The takeaway
Understanding the timeline of ancient human migration helps clarify the long-term history of human interaction with regional ecosystems. This discovery underscores the importance of ongoing field research in reconstructing the early history of South American habitation.
What happens next
Researchers will continue to analyze sediment and bone remains to further clarify the exact timeline of human arrival and the specific butchery techniques employed at the lake basin.
