Journal ArticleDOI

Roy Larick,Russell L. Ciochon,Yahdi Zaim,Sudijono,Suminto,Yan Rizal,Fachroel Aziz,Mark K. Reagan,Matthew T. Heizler +8 more
TL;DR: This work investigates the sedimentary framework and hornblende 40Ar/39Ar age for volcanic deposits in the southeast quadrant of the Sangiran dome, and identifies a sequence of sedimentary cycles in which H. erectus fossils are associated with epiclastic pumice.
Journal ArticleDOI
Last appearance of Homo erectus at Ngandong, Java, 117,000–108,000 years ago

TL;DR: Bayesian modelling of radiometric age estimates provides a robust chronology for Homo erectus at Ngandong, confirming that this site currently represents the last known occurrence of this long-lived species.

Journal ArticleDOI
New 1.5 million-year-old Homo erectus maxilla from Sangiran (Central Java, Indonesia)

TL;DR: The dental patterns suggest distinct demic origins for the earlier H. erectus populations represented at Sangiran and the later population represented at Zhoukoudian, suggesting these two east Asian populations may have had separate origins from different African/west Eurasian populations.
Journal ArticleDOI
Early hominin biogeography in Island Southeast Asia.
Roy Larick,Russell L. Ciochon +1 more
TL;DR: In this article, the authors reviewed the evidence across three Pleistocene climate periods and discussed patterns in relation to the pulse of global sea-level shifts and regional geo-tectonics, catastrophes, stegodon dispersal, and paleogenomics.
