Scientists have identified some of the earliest cave paintings produced by humans.
The artworks are in a rural area on the Indonesian Island of Sulawesi.
Until now, paintings this old had been confirmed in caves only in Western Europe.
Australian and Indonesian scientists have dated layers of stalactite-like growths that have formed over coloured outlines of human hands.
Early artists made them by carefully blowing paint around hands that were pressed tightly against the cave walls and ceilings. The oldest is at least 40,000 years old.
