Palaeoanthropological Study of Homo erectus Fossils in Java

自从Dubois在爪哇中部首次发现古人类以来，印度尼西亚已经发现了一批更新世古人化石。由于这些丰富的材料，印尼一直是东亚地区人类进化研究的最重要的地方。本研究的主要目的是通过对印度尼西亚发现的更新世古人遗骸的调查，为了解东亚人口进化史的性质做出贡献。本研究期间开展的主要工作如下：1.对第四纪地质实验室保存的古人化石进行了形态观察，2.用于比较研究的原始人化石测量.3.第四纪地质实验室存放的Sangiran 17的铸件制作.4.使用这些种姓重建Sangiran 17.5.根据4.6的结果重建Sangiran 17原始标本.6.在爪哇主要的原始人化石承载地点(Trin il、Sangiran、Ngong、Sambungmachan、Perning、Punung、Pacitan、Wadjak、Miri、PatiAyam、Sonde、KedungBrubus、Ngawi，在本次调查中，在桑吉兰地区发现了两个新的原始人化石。7.确认了桑吉兰地区几个原始人化石的发现地点。8.野外对这些化石的地层成分进行了检验。9.通过多元素骨骼分析对这些化石的地层背景进行了研究。10.在桑吉兰地区进行了试掘。通过上述活动获得的形态数据在日本进行了分析，结果已发表在其他几篇论文中。其他活动的结果将在不久的将来报告。

Since Dubois'first find of a Pithecanthropus in Central Java, Indonesia has yielded a number of Pleistocene hominid fossils.Thanks to these rich materials, this country has always been the most important place for human evolutionary study in East Asia.The main pupose of the present research is, by investigating Pleistocene hominid remains recovered in Indonesia, to make a contribution to understanding on the nature of evolutionary history of East Asian populations.Main activities performed during this research period are as follows :1.Morphological observation on the hominid fossils housed in Quaternary Geology Laboratory, Bandung.2.Measurements of the hominid fossils for comparative studies.3.Cast making of the Sangiran 17 housed in Quaternary Geology Laboratory.4.Reconstruction of the Sangiran 17 using these casts.5.Reconstruction of the Sangiran 17 original specimen based on the results of 4.6.General survey at the major hominid fossil bearing sites in Java (Trinil, Sangiran, Ngandong, Sambungmachan, Perning, Punung, Pacitan, Wadjak, Miri, PatiAyam, Sonde, Kedungbrubus, Ngawi, Widodaren).Two new hominid fossils were obtained from the Sangiran region during this survey.7.Confirmation of findspots for several hominid fossils from the Sangiran region.8.Examination of stratigraphic conterxt for these fossils in the field.9.Examination of stratigraphic context for these fossils by multielement analyzes of bones.10.Test excavation in the Sangiran region.Morphological data obtained through the above activities were analyzed in Japan and the results habe been published in a few papers listed elsewhere.Results of the other activities will be reported in near future.
