The black and greenish-black colors indicate Bing\u00f6l. Both blade and flake industry are seen but the blade industry is smaller than the flake industry.  Obsidian could have been brought partly as raw material and/or partly as a core or in an incipient stage of production.  The main bulk is comprised of unretouched small blades and flakes that might have been used for hide work or for cutting soft plants. \r\nFlint as a raw material is from local sources and is less frequent than obsidian. Direct percussion techniques have been used in flint knapping. Smooth blades are very few, and only one broken bullet core has been uncovered. A few fine brown and grey flints were brought from abroad.", "lithics_technology": [1], "research_event": 5, "lithics_core_shape": [1], "lithics_raw_material": [2, 1], "animal_remains_completeness": null, "lithics_retouched_tools": [15, 7, 8], "botany_species": [], "area": 3, "obsidian": "Yes", "confidence": "5", "small_finds_category": null, "pottery_form": null, "public": true, "amount": null, "animal_remains_species": [], "small_finds_type": [], "lithics_industry": [1, 2], "animal_remains_part": [], "reference": ["7X28C9PV", "BFXRW328", "UTEECGBE"], "pottery_detail": []}, "model": "defcdb.finds"}]
