Toward the settlement of controversies over the chronology of the early Javanese hominids

对印度尼西亚爪哇的原始人类化石进行了年代学研究。我们的研究结果约束的最高年龄（最新出现）的原始人类化石约0.79马（百万年前）在Sangiran地区，产生了一些直立人的发现，也提供了一个标准的上新世更新世部分在爪哇。在这些日子里，原始人在1.5 Ma之前首次殖民爪哇的想法已经被广泛接受。然而，目前的研究未能支持上述“公认”的年代学概念，并强烈建议爪哇人最早的已知遗骸不应追溯到远超过1.0 Ma。

Geochronological research was carried out on the fossil hominid remains from Java, Indonesia. Our results constrains the uppermost age (latest occurrence) of hominid fossils to about 0.79 Ma (million years ago) in the Sangiran area, which has yielded a number of Homo erectus finds and also offers one of the standard Plio-Pleistocene sections in Java. In these days, the idea has become widely accepted that hominids achieved the first colonization into Java earlier than 1.5 Ma. However, the present research fails to support the above "accepted" chronological concept, and strongly suggests that the earliest known remains of the Javanese hominids should not date back far more than 1.0 Ma.
