"Rock paintings are traces left by early humans during hunting and are among the earliest conscious creations by humans," says Zhang Yasha, professor from the China rock art center with Minzu University of China. "The newly discovered rock paintings in the Haizishan region exhibit many stylistic features reminiscent of prehistoric rock paintings, in terms of the themes, image sizes, pattern characteristics and painting techniques, and they may be related to the unique rock art clusters of the Paleolithic era in Southwest China," Zhang says. "Most rock paintings we find are sculpted into the rock and represent abstract symbols, but the new ones were drawn, which is rare on plateau, and they depict evident hunting elements, with distinctive wild animals," says Zhou, who has conducted field investigations at over 150 independent rock painting sites on the Qinghai-Tibet Plateau. Therefore, Zhou holds that the ancient population behind these discovered painted rock art sites should provide unique insights for the study of prehistoric life on the Qinghai-Tibet Plateau.
