Researchers have discovered what is believed to be the world’s oldest painting – a life-sized picture of a wild pig that is at least 45,500 years old in Indonesia. Co-author of the study, Maxime Aubert said that the painting was discovered by a doctoral student in Basran Burhan in Leang Tedongnge cave located in Sulawesi. It was painted using dark red ochre pigment and depicts social activities among other warty pigs.

Aubert shared in an interview with the Science Advances journal that people during that time were already “modern”. They were already capable and could use tools to create paintings that they liked. The painting gives evidence of human settlement in the region, filling out blank spaces in archeological records. Adam Brumm, co-author of the study, believes that there are older artworks in the area that are waiting to be discovered. “It just shows how much artwork is there waiting to be found on this island. It’s hiding in plain sight.”
