A great variety of artifacts, in different traditions and periods were found. The obsidian is probably the most largely diffused one. Finds: bifacial preforms, pyramidal unipolar cores, bi-directional cores, prismatic pressure bladelet cores, naviform cores. Roughouts or preforms were taken out to be knapped at the settlements; the whole knapping sequence was performed at the workshop, only the intended central blades were exported. Different knapping strategies were used over different periods. It is one of the richest workshops ever discovered.", "settlement_special_features": [], "radiocarbon_dated": null, "cemetery_or_graves_topography": [], "dating_method": [], "earliest_date_14C_age": null, "cemetery_or_grave": null, "latest_date_14C_age_calibrated": null, "earliest_date_lab_number": "", "area_type": 5, "settlement_type": null, "created": "2016-09-06T19:22:33.054Z", "settlement_human_remains": null, "latest_date_standard_deviation": null, "grave_type_of_human_remains": [], "settlement_structure": [], "earliest_date_calibration": null, "grave_manipulations_of_graves": [], "modified": "2016-09-06T19:22:33.054Z", "grave_age_groups": [], "latest_datedated_by": [], "grave_estimated_number_of_individuals": "", "earliest_date_delta13": null, "area_nr": "", "latest_date_date_of_calibration": null, "latest_date_calibration": null, "latest_date_delta13": null, "grave_number_of_graves": "", "grave_number_of_female_sex": null, "earliest_date_14C_age_calibrated": null, "cave_rockshelters_human_remains": null, "cave_rockshelters_type": null}, "model": "defcdb.area", "pk": 754}]
