Since World War II, like specimens have been found in Mokrica Cave () and Betal Rock Shelter (). These bones are preserved today at the National History Museum of Slovenia as well. According to Mitja Brodar, who discovered many of them, bones with holes have been dated only to the end of the Mousterian and the beginning of the Aurignacian, and have not yet been found in Western Europe. Brodar assumes these bones are still not recognized by the international research community due to the fact that most of them were found in France, and the Paleolithic is still considered to be the French's domain. Bones with holes such as those found in the Potok Cave have been ascribed to modern human Cro-Magnon, and Mitja Brodar asserts that they are an element of the Central European Aurignacian. He further posits that the Divje Babe Flute is a product of modern humans, but this has been disputed by other Slovene scholars.
