The figurine was found 15 metres below ground

The object, which is around six centimetres in length, is shaped like a human figure, with grooves that suggest a neck, arms and legs. On its surface are flakes of a red substance that could be remnants of paint.

The object was found 15 metres below the eroded surface of a terrace on the north bank of the river Draa near the town of Tan-Tan. It was reportedly lying just a few centimetres away from stone handaxes in ground layers dating to the Middle Acheulian period, which lasted from 500,000 to 300,000 years ago.

Cultural controversy

The find is likely to further fuel a vociferous debate over the timing of humanity's discovery of symbolism. Hominids such as Homo heidelbergensis and Homo erectus, that were alive during the Acheulian period, are not thought to have been capable of the symbolic thought needed to create art.

Writing in the journal Current Anthropology, Robert Bednarik, president of the International Federation of Rock Art Organisations (IFRAO), suggests that the overall shape of the Tan-Tan object was fashioned by natural processes.
