Pedra Furada sites

Pedra Furada (Portuguese pronunciation: [ˈpɛdɾɐ fuˈɾadɐ], meaning pierced rock) is an important collection of over 800 archaeological sites in Brazil, including numerous rock paintings, which suggest a human presence prior to the arrival of Clovis people in North America. A Brazilian and French team excavating a site located in the Southeastern portion of the state of Piauí in what is now the Serra da Capivara National Park discovered the site in 1973. The discovery was reported by the Brazilian archaeologist Niède Guidon, who published her findings in 1986.
