The study of organic remains in archaeological Sites, focussing on plants and animal remains in wetland

1. 不同考古遗址特别是湿地条件下微小动植物遗存采集技术的发展人类活动的鉴定，如墓葬、家庭生活等，是通过对土壤中有机残留物的无机成分的分析而发展起来的。利用土壤微形态技术对坑式民居的耕地和地面水平进行了鉴定。该方法也为在显微镜下直接对考古土壤中的微遗存进行地层观察提供了可能。新泻县Ushimichi遗址（公元12年）发现的Tomiyo（棘鱼）是该物种在考古单位的现场报告中首次发现。广岛大学在古博大木洞遗址发现了大鲵，这是首次在考古遗址上发现大鲵，并在现场报告中证实了绳纹人早在8000年前就开始利用大鲵了。在大阪的长原遗址，讨论了将死马和死牛用于皮革、医药等的利用技术。D)在其现场报告中。

1. Developing of the collecting technique for the micro animal and plant remains from various archaeological features especially in wetland condition.2. The identification of the human activities such as burials, household and so on, is developed by means of analysis of inorganic contents which derived from organic remains in the soil.3. Identification of cultivated fields and floor level in the pit dwellings is developed by means of soil micromorphological techniques. Also this method made it possible to observe the microremains directly in the archaeological soil stratigraphically under the microscope.4. Discovery of Tomiyo (stickleback : ) from Ushimichi site (12A.D.) in Niigata Prefecture is the first report of this species in archaeological sties in its site report.5. Discovery of Giant Salamander from Kobo-daki Cave site which conducted by Hiroshima University is the first report from archaeological sites and certified that the Jomon people exploited it since the earliest Jomon, 8000bp in its site report.6. The utilization technique of the dead horse and cattle for leather, medicine, and so on, is discussed at the Nagahara site, Osaka (7 A.D) in its site report.
