<P> The oldest date given to an animal cave painting is now a pig that has a minimum age of 35,400 years old at Timpuseng cave in Sulawesi , an Indonesian island . Indonesian and Australian scientists have dated other non-figurative paintings on the walls to be approximately 40,000 years old . The method they used to confirm this was dating the age of the stalactites that formed over the top of the paintings . The art is similar in style and method to that of the Indonesian caves as there were also hand stencils and disks made by blowing paint onto the walls . Cave paintings in El Castillo cave were found to date back to at least 37,300 years old by researchers at Bristol University , making them the oldest known cave art in Europe , 5 -- 10,000 years older than previous examples from France . This date coincides with the earliest known evidence for Homo sapiens in Europe . Because of the cave art 's age , some scientists have conjectured that the paintings may have been made by Neanderthals . </P>
