Very recently several petroglyphs at the rock art site of Guelta Oukas in the Anti Atlas Mountains of southern Morocco were severely damaged. However, the mutilation was limited to two panels with mainly depictions of cattle and – moreover – to specific body parts of those zoomorphic images. In this paper I argue that this is not just another case of unwanted vandalism. Instead, I propose that the mutilation at Guelta Oukas could represent an instance of ‘negative’ rock art, involving the desecration of the images.
