These included hundreds of rock paintings, which suggest a human presence prior to the arrival of Clovis people in North America. In 1973, a Brazilian and French team excavating a site located in the southeastern portion of what is now the Serra da Capivara National Park discovered the first finds. The discovery was reported by the Brazilian archaeologist Niède Guidon, who published her findings in 1986.〔Guidon, Niède y G. Delibrias. 1986 "Carbon-14 dates point to man in the Americas 32 000 years ago"; Nature 321: 769-771〕 She has since conducted extensive excavations and published other findings. ==Excavations== Pedra Furada includes a collection of rock shelters used for thousands of years by human populations. The first excavations yielded charcoal deposits with Carbon-14 dates of 48,000 to 32,000 years BP. Repeated analysis has confirmed this dating, carrying the range of dates up to 60,000 BP.〔Guidon, Niède. 1986 "Las Unidades Culturales de Sao Raimundo Nonato - Sudeste del Estado de Piaui-Brasil"; ''New Evidence for the Pleistocene Peopling of the Americas:'' 157-171. Edited by Alan Bryan. Center for the Study of Early Man. University of Maine. Orono.〕 A review of the site by archaeologist Tom Dillehay in 1994 suggested that the charcoal remains may have been from natural fires and were not necessarily indicative of human occupation. Guidon has established 15 distinct levels, classified in three cultural phases, called ''Pedra Furada'', that includes the oldest remains; and ''Serra Talhada'', from 12,000 to 7,000 BP, with tools such as knives, scrapers, flakes used "as is" or with some retouch and lithic cores, all made of quartz or quartzite. Third is ''Agreste'' late phase. The site also has hundreds of rock paintings dated from 5,000 to 11,000 years ago.〔("Pedra Furada, Brazil: Paleoindians, Paintings, and Paradoxes: An interview with Drs.
