KOZARNIKA CAVE (Nikolai Sirakov – nikolaysirakov@gmail.com, Jean-Luc Guadelli) Layers of the beginning of the Upper Paleolithic period were explored in Sectors DE7–DE10 in the entry hall of the cave and in Sector III in beginning of the gallery towards its interior, relevant to the early and partly to the middle phases of the Kozarnika Culture (39,000 – 26,000 BP). The flint assemblages of the early phases of the Kozarnika Culture displayed a technological variety. The artifacts included arrowheads and elements of complex tools (knives, saws, small awls and scrapers). The sporadic presence of Mousterian shapes in the transition to the earliest phase of the Kozarnika Culture (42,000 – 39,000 BP) indicated the end of the transition from the Middle to the Upper Paleolithic period. Aurignacian artifacts were found in Sector III: two flint scrapers and a flake and a fragment of a bone point dated to 34,500 – 31,000 BP. The faunal remains indicated hunting of deer, wild goats, horses, oxen and predators.
