Lubang Jeriji Saléh is a limestone cave complex in Indonesia, located within the Sangkulirang-Mangkalihat Karst in the remote jungle of the Bengalon district of East Kutai Regency, East Kalimantan province, on Borneo island. In 2018, a team of researchers announced the discovery of what was then believed to be the oldest known work of figurative art in the world among the cave paintings, dating back 40,000 years. However, the same team has since found and dated an elaborate therianthrope rock art panel in the Leang Bulu' Sipong 4 cave in Sulawesi's Maros-Pangkep karst to approximately 44,000 years ago.
