It encompassed 21 bifacial points that were horizontally disposed on the ground. Half of the points were 12 cm long, the rest was longer than 18 cm and one almost 25 cm, which leads to the assumption that there were highly skilled workers involved in making these. The points were not shaped from a plain nucleus, but on very large, long blades (around 6 cm).", "botany_species": [], "pottery_decoration": [], "pottery_form": null, "confidence": null, "obsidian": "Yes", "lithics_technology": [], "small_finds_category": null, "modified": "2016-10-01T19:26:26.278Z", "animal_remains_completeness": null, "created": "2016-10-01T19:26:26.278Z", "finds_type": 3, "obsidian_amount": null, "small_finds_type": [], "pottery_detail": [], "lithics_retouched_tools": [16, 8], "lithics_raw_material": [1], "animal_remains_part": [], "animal_remains_species": []}, "pk": 1823, "model": "defcdb.finds"}]
