In 2014, a stone tool was found in the Gediz River that was securely dated to 1.2 million years ago. Evidence of paleolithic (prehistory 500,000–10,000 BC) habitation include the Yarimburgaz Cave (Istanbul), Karain Cave (Antalya), and the Okuzini, Beldibi and Belbasi, Kumbucagi and Kadiini caves in adjacent areas. Examples of paleolithic humans can be found in the Museum of Anatolian Civilizations (Ankara), in the Archaeological Museum in Antalya, and in other Turkish institutions.
