World's oldest known cave painting found in Indonesia

Archaeologists have discovered the world's oldest known cave painting: a life-sized picture of a wild pig that was made at least 45,500 years ago in Indonesia.

This makes the painting at least that age, "but it could be much older because the dating that we're using only dates the calcite on top of it,"
"The people who made it were fully modern, they were just like us, they had all of the capacity and the tools to do any painting that they liked,"


The previously oldest dated rock
art painting was found by the same team in Sulawesi. It depicted a group of part-human, part-animal figures hunting mammals, and was found to be at least 43,900 years old.
