Large rock‐shelter in the sandstone hills of the Sierra Talhadra in the Piauí region of eastern Brazil. Excavated by Niede Guidon in the 1970s and 1980s, the site yielded a long sequence from Palaeo‐Indian times onwards. The walls of the rock‐shelter are adorned with paintings, fragments of which have been found in stratified layers dating to about 10 000 bc. Earlier levels dating to before 39 200 years ago have yielded quartzitic artefacts.
