Archaeological sites attributed to the Iron Age in Taiwam are mainly distributed along the coastal plain areas (see Fig.1).Most of them had been excavated in recent years, and yielded large amount of important archaeological material. Based on these findings and the chronlogical information, the author revised her earlier views about the prehistoric cultural sequence (see Fig. 2) in the text and pointed out some distinct cultural characteristics of this age synchronically and diachronically. The findings illustrate a higher technique of pottery making with geometric impressed patterns, and a stone inventory which differs from the earlier stages ,retarded in technique which appears to be related to an emerging iron industry .Eventually the jade industry which was highly developed in the Neolithic became extinct. The author also noticed the absence of the custom of tooth extraction. In addition to iron, many new items appearin this stage, such as implements or ornaments made from the materials of prosperous glass, agate, bronze, silver, andg gold. In addition, particular forms of burial were practiced in this stage, such as the prone and extended burials in wast central Taiwan, and the lateral and flexed burials in the north, and on impershable material used as coffins were found. The mentioned cultural traits of the early Iron Age of Taiwan were reported to be distinct from those of the Neolithin Cultures of Taiwan, and from those of the existing aborigines.
