Oldest Known Cave Art Discovered in Indonesia’s Sulawesi Island

The faint outline of a human hand discovered in a cave in eastern Indonesia is the world’s oldest known example of rock art, according to a new study.

The hand stencil, found in a limestone cave known as Liang Metanduno on the island of Sulawesi, was dated to at least 67,800 years ago, a team of researchers said in an article published Wednesday in the journal Nature.
