Scientific publications should always be reliable. The content may never be incorrect or misleading. This also goes for publications regarding rock art, whether by amateurs or by academics. This short paper deals with two photographs of petroglyphs from the Majes Valley, southern Peru, and the conclusions based upon those illustrations published by two academics from the USA. Regrettably, both the photos and the conclusions are unambiguously incorrect.
