Palaeoanthropological Study of Homo erectus Fossils in Java

自从杜布瓦在中爪哇首次发现猿人以来，印度尼西亚已经发现了许多更新世的原始人类化石。由于这些丰富的资料，这个国家一直是东亚人类进化研究最重要的地方。本研究的主要目的是通过调查在印度尼西亚发现的更新世古人类遗骸，为了解东亚种群进化历史的本质作出贡献。本研究期间的主要活动如下：1。2.万隆第四纪地质实验室古人类化石的形态观察。为比较研究而测量原始人化石。第四纪地质实验室桑吉兰17号的铸造制作。使用这些铸件重建桑吉兰17号。基于4.6的结果重建Sangiran 17原始标本。爪哇主要古人类化石产地（Trinil、Sangiran、Ngandong、Sambungmachan、Perning、Punung、Pacitan、Wadjak、Miri、PatiAyam、Sonde、Kedungbrubus、Ngawi、Widodaren）的总体调查。在这次调查中，在桑吉兰地区发现了两具新的古人类化石。确认桑吉兰地区几个原始人类化石的发现地点。这些化石在野外的地层环境检查。通过对骨骼的多元素分析来检查这些化石的地层环境。桑吉兰地区的试验挖掘。通过上述活动获得的形态学数据在日本进行了分析，结果已发表在其他地方列出的几篇论文中。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.
