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 60 potsherds of the Earliest and Early Jomon period have been dated. The measured values of δ ^<13>C were about -25%o, 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 various types and conditions.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). Shell specimen were selected in the old shell collection of the University Museum, the University of Tokyo, and dated.

对陶器碎片本身进行了直接测年，在适当的条件下进行适度的化学处理就可以去除污染物。测量值​​δ 13 C 约为-25％，并且C 4 植物没有被用作有机材料。观察到纤维的痕迹残留在陶瓷碎片的表面或内部。通过扫描电镜观察，发现纤维的类型和状况各不相同。根据三陆地区贝丘的样本，对同一层出土的贝壳和木炭遗骸进行了测量和比较。贝壳样本比木炭碎片年代早200-300年，贝壳样本的年代应采用区域校正值（ΔR）进行校准，贝壳标本选自大学博物馆的旧贝壳收藏。东京大学，并注明日期。
