REDAKA 2 CAVE (Aleta Guadelli – aleta.guadelli@gmail.com, Jean-Luc Guadelli, Nikolai Sirakov, Ivailo Krumov) The explorations of the Upper Paleolithic layers in Stratum 4b continued in Sectors DE/5-6. There were finds from the Middle and the Upper Paleolithic periods in the lower part of Stratum 4b: Upper Paleolithic flint plates and two Middle Paleolithic nuclei with Levallois features. The discovered bones belonged to ox (Bovinae), deer (Cervidae), including reindeer (Rangifer tarandus), hyenas (Crocuta crocuta spelaea), a fox (Vulpes vulpes) and a cave bear (Ursus spelaeus). The taphonomic study showed that a significant part (28.40%) of the bone fragments had traces indicating that they were consumed by hyenas and only 1.95% had traces from human activity. The data showed that one and the same cave was visited by hunters and hyenas at relatively short intervals in the period from 39/36 to 25 ka BP.
