By developing a new methodology for handling and assessing a large number of shoreline dated sites, this paper compares the summed probability distribution of radiocarbon dates and shoreline dates along the Skagerrak coast of south-eastern Norway. Both measures have previously been compared to elucidate demographic developments in Fennoscandia, but these have not been based on probabilistic methods for shoreline dating. The findings indicate a largely diverging development of the two data sets through the Mesolithic. The number of shoreline dated sites undergoes some process of overall decrease through the period, while the radiocarbon data is characterised by a lacking signal in the earliest parts of the period and then undergoes a logistic growth that quickly plateaus and remains stable for the remainder of the period. The precise nature of this discrepancy will necessitate further substantiation and the method of shoreline dating itself still requires further testing and assessment. Having noted this, we still tentatively suggest that while the number of shoreline dated sites is not devoid of influence from a demographic signal, this measure could be more heavily influenced by mobility patterns. Conversely, we also suggest that the lacking radiocarbon data from the earliest part of the Mesolithic is in part the result of mobility patterns, but that the radiocarbon data could be reflecting population dynamics more directly.

比较挪威中石器时代 Skagerrak 海岸的海岸线和放射性碳测年的总概率分布
通过开发一种处理和评估大量海岸线测年地点的新方法,本文比较了挪威东南部 Skagerrak 海岸沿线放射性碳测年和海岸线测年的总概率分布。以前曾对这两种措施进行比较以阐明 Fennoscandia 的人口发展,但这些措施并非基于海岸线测年的概率方法。研究结果表明,这两个数据集在中石器时代的发展在很大程度上不同。在此期间,海岸线测年地点的数量经历了一些总体减少的过程,而放射性碳数据的特点是该时期的最初阶段缺乏信号,然后经历了一个物流增长,迅速趋于平稳,并在该时期的剩余时间内保持稳定。这种差异的确切性质需要进一步的证实,而海岸线测年的方法本身仍需要进一步的测试和评估。注意到这一点后,我们仍然试探性地认为,虽然海岸线测得遗址的数量并非没有人口信号的影响,但这一衡量标准可能更严重地受到流动性模式的影响。相反,我们还认为,中石器时代最早部分缺乏放射性碳数据的部分原因是流动性模式的结果,但放射性碳数据可以更直接地反映种群动态。
