Chronology of the Stone Age hunter-gather site Szczepanki, Masuria, NE-Poland

Data set includes results of AMS measurements - 14C Age (yrBP) along with calibrated age (cal. BC) and isotope measurements (15N, 13C) in case of bone samples (collagen). Table include the information about the sampled material and all important archaeological data. All results of AMS radiocarbon and isotope (EA-IRMS) measurements were obtained in 2024 year thanks to NCN grant project: Absolute chronology of burials and loose human bones from the hunter-gatherer Stone Age sites Dudka and Szczepanki in Masuria (NE-Poland) (Grant no. 2020/39/B/HS3/02375).28 charcoals and 31 bones were selected for radiocarbon dating and stable isotope measurement (bones). All charcoals were measured, however, few of them gave results which are contrary to the stratigraphy and other obtained dates. It could be a result of a bad preservation of charcoal or most probably by the layer disturbances. From the selected bones only 18 can be measured. 15 samples were dated along with stable isotope measurement, while for 2 samples only EA-IRMS measurements were made.Radiocarbon AMS dating of charcoal samples was made in the laboratory: Vilnius Radiocarbon in Lithuania. Bone and tooth samples were measured in Tandem Laboratory of Uppsala University in Sweden and in Vilnius Radiocarbon Laboratory in Lithuania.Calibrated BC dates (95% confidence intervals) provided in the table are based on: OxCal v.4.4.4 (Bronk Ramsey 2021r), IntCal20 curve (Reimer et al. 2020).Methods used by laboratories are numbered included in the instruction to table (readme.txt).

本数据集包含AMS测量（Accelerator Mass Spectrometry）的结果——14C年龄（yrBP）、校正年龄（cal. BC）；对于骨骼样本（胶原蛋白，collagen），还涵盖同位素测量（15N、13C）数据。
表格包含采样材料的相关信息及所有重要考古数据。
所有AMS放射性碳测量与同位素（EA-IRMS，Elemental Analysis-Isotope Ratio Mass Spectrometry）测量结果均于2024年通过NCN资助项目获取，项目名称为：‘波兰东北部马祖里地区狩猎采集石器时代遗址Dudka与Szczepanki的墓葬及散存人骨绝对年代学研究’（资助编号：2020/39/B/HS3/02375）。
研究选取28份木炭样本与31份骨骼样本，用于放射性碳定年及稳定同位素测量（针对骨骼样本）。
所有木炭样本均已完成测量，但少数样本结果与地层学记录及其他已得年代数据存在冲突。
这一现象可能源于木炭保存状况不佳，更可能是地层扰动所致。
在选取的骨骼样本中，仅18份具备测量条件。
其中15份样本同步完成了年代测定与稳定同位素测量，另有2份样本仅开展了EA-IRMS测量。
木炭样本的放射性碳AMS定年工作由立陶宛Vilnius Radiocarbon实验室完成。
骨骼与牙齿样本的测量则在瑞典乌普萨拉大学串联实验室（Tandem Laboratory）及立陶宛Vilnius Radiocarbon实验室开展。
