A prehistoric human skull and 6,000 animal fossils were discovered in the Madura Strait, Indonesia, shedding light on the ancient landmass of Sundaland, which was home to venomous Komodo dragons. The skull fragments, dating back 140,000 years, suggest that Homo erectus may have developed unique hunting strategies influenced by interaction with more modern human species. This significant find, detailed in the Quaternary Environments and Human journal, highlights the diverse prehistoric ecosystem and the potential cultural exchange between early human populations.
