It was difficult to compile dates of archaeological sites with shell midden. There were not so many dates those were reported with the contemporary type of pottery in detail. Shell and charcoal remains excavated from the same layer as pairs were measured and compared. According to the sample of the shell midden in the Sanriku district, the ages of the shell samples are 200-300 years older than those of charcoal fragments. The dates of shell samples should be calibrated with the regional correction value (ΔR).Direct dating of a potsherd itself has been investigated for 'fiber-tempered pottery'. Contaminants alone can be removed when a suitable moderate condition of chemical treatment. About 40 potsherds of the Earliest and Early Jomon period have been dated. The measured values of δ ^<13>C were about 25‰, and C4 plants have not been used as a organic temper. The impression of fiber, remained on the surface or inside of the potsherd, was observed by SEM using the replica method. The fiber was seemed to be short and straight.Our project is now reconstructed for a successive investigation.

根据对同一层出土的贝壳和木炭遗骸的详细记录，很难统计出贝冢考古遗址的年代。三陆地区的贝冢样本，贝壳样本的年龄比木炭碎片的年龄要早200-300年，贝壳样本的年代应使用区域校正值进行校准。 (ΔR)。对陶器碎片本身进行了直接测年，对大约 40 个最早和早期绳文时代的陶器碎片进行了测年，仅污染物就可以被去除。 δ^<13>C的测量值约为25‰，并且C4植物没有被用作有机纤维的印记，保留在纤维的表面或内部。使用复制法通过扫描电镜观察到陶瓷碎片，纤维似乎又短又直。我们的项目现在正在重建以进行后续研究。
