2020年1月10日，日本国立科学博物馆Shuji Matsu’ura、神户大学Masayuki Hyodo等研究人员合作在《科学》上发表论文，揭示了桑吉兰地区爪哇直立人首次出现时间测定。

据悉，印度尼西亚的桑吉兰世界遗产地的年代顺序对于了解人类在早更新世（780,000年前）的传播和定居至关重要。然而，这一直是存在争议的，特别是关于最早的古人类迁移到桑吉兰地区的时间。

Abstract: The chronology of the World Heritage Site of Sangiran in Indonesia is crucial for the understanding of human dispersals and settlement in Asia in the Early Pleistocene (before 780,000 years ago). It has been controversial, however, especially regarding the timing of the earliest hominin migration into the Sangiran region. We use a method of combining fission-track and uranium-lead dating and present key ages to calibrate the lower (older) Sangiran hominin-bearing horizons. We conclude that the first appearance datum for the Sangiran hominins is most likely ~1.3 million years ago and less than 1.5 million years ago, which is markedly later than the dates that have been widely accepted for the past two decades.
