Toca da Tira Peia

The excavation site contains multiple sediment layers holding stone tools and artifacts within a natural rock formation near Serra da Capivara National Park.

Researchers discovered 113 stone artifacts across five soil layers during excavations between 2008 and 2011, indicating human presence dating back 22,000 years.

The findings at this location contribute to understanding early human settlements in South America, challenging previous theories about the continent's first inhabitants.

Scientists use optically stimulated luminescence techniques to analyze quartz grains for dating the archaeological materials found at different depths.

The site maintains undisturbed artifact positions since their burial, providing researchers with reliable data for archaeological interpretations.
