The bone flute was discovered in 1995 in the cave of Divje babe near Cerkno during systematic excavations led by Ivan Turk. The cave lies below the north-eastern edge of the Šebrelje plateau, 230 meters above the Idrijca River. The cave in which it was found was a den of cave bears, but in the last glacial period it was occasionally also visited by people, initially Neanderthals and afterwards anatomically modern humans. The flute was found close to a hearth, in a layer deposited about 60 to 50 millennia ago.
