摘要

The thermoluminescence technique was used to date 40 burnt quartz pebbles from the lowest layers (PF1 and PF2) of the Toca do Boqueirao da Pedra Furada rock shelter (Piaui, Brazil) attributed to Upper Pleistocene period, whose radiocarbon ages exceed 35 ka. Our results suggest that the quartz specimens were burnt between 30 and more than 100 ka ago, but they provide no evidence that the heating was related to human activity.
