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

1.从不同的考古特点，特别是湿地条件下，发展微型动植物遗骸的采集技术。通过对土壤中有机残留物中无机成分的分析，开展了对埋葬、家居等人类活动的识别。利用土壤微形态技术对坑居的耕地和地面水平进行了鉴定。这种方法也使得在显微镜下直接观察考古土壤中的微遗迹成为可能。Ushimichi遗址(公元12年)发现的Tomiyo(刺鱼：)在新泻县的遗址报告中，首次报道了该物种在考古领域的情况。广岛大学在考博-达基洞穴遗址中发现了大火蜥蜴，这是考古遗址的第一份报告，在其遗址报告中证明了所罗门人从最早的时候就对其进行了开发，8000个基点。在大阪长原遗址(公元7年)的遗址报告中，讨论了利用死马和死牛制作皮革、医药等的技术。

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.
