Ngandong fossils are Homo erectus calvaria and tibia from Java. Fossils dated 117-108 thousand years old via Bayesian modeling of 52 radiometric dates. Ngandong terrace formed 140-92 thousand years ago. Non-human fossils at site aged 109-106 thousand years by uranium-series and 117-108 thousand years by US-ESR. Skulls larger and more advanced than Sangiran or Trinil Homo erectus. Homo erectus inhabited Java over 1.5 million years. Latest known Homo erectus in Southeast Asia. Dating resolves prior chronological inconsistencies. Flood accumulation preserved fossils. Supports biostratigraphic position in SE Asian hominin sequence. Dispels claims fossils too young for Homo erectus. Used U-series speleothem, luminescence, and Ar-Ar dating on sediments. Solo River terrace sequence 316-31 thousand years old. Regional tectonics shifted river 500 thousand years ago.
