Toca da Tira Peia

The Toca da Tira Peia site is a rock shelter located in the municipality of Coronel José Dias, Piauí, Brazil. This archaeological site is significant for its evidence of prehistoric human presence dated to approximately 22,000 years ago. The site contains four sediment layers, the oldest of which has been dated using optically stimulated luminescence. A total of 113 stone artifacts, including tools and tool debris, were found across these layers, providing crucial insights into early human activity in South America. The absence of naturally occurring pebbles, which can complicate dating at other sites, enhances the reliability of Toca da Tira Peia's findings. This site contributes to the understanding of the Upper Paleolithic period in the region, offering evidence of early human technology and habitation patterns.
