At Quesang on the Tibetan Plateau we report a series of hand and foot impressions that appear to have been intentionally placed on the surface of a unit of soft travertine.The travertine was deposited by water from a hot spring which is now inactive and as the travertine lithified it preserved the traces.On the basis of the sizes of the hand and foot traces,we suggest that two track-makers were involved and were likely children.We interpret this event as a deliberate artistic act that created a work of parietal art.The tra-vertine unit on which the traces were imprinted dates to between ~169 and 226 ka BP.This would make the site the earliest currently known example of parietal art in the world and would also provide the ear-liest evidence discovered to date for hominins on the High Tibetan Plateau (above 4000 m a.s.l.).This remarkable discovery adds to the body of research that identifies children as some of the earliest artists within the genus Homo.
