Habitat comments: "the sediments of unit B2 consist mainly of carbonates and organic matter, whereas siliceous compounds are few... Ash and charcoal occur abundantly... Fire activity is remarkable... Taphonomic evidence of cut-marks, percussion damage and thermal modification show that most of the faunal remains were brought and processed into the cave by humans"
