Human settlement during the Paleolithic has not yet been confirmed by archaeological expeditions. The earliest archaeological evidence of organized settlement, which have been found in Kosovo, belong to the Neolithic Starčevo and Vinča cultures. Vlashnjë and Runik are important sites of the Neolithic era. The rock art paintings at Mrrizi i Kobajës, near Vlashnjë are the first find of prehistoric art in Kosovo. Amongst the finds of excavations in Neolithic Runik is a baked-clay ocarina, which is the first musical instrument to ever be recorded in Kosovo. The beginning of the Bronze Age coincides with the presence of tumuli burial grounds in western Kosovo as in the site of Romajë.
