Stone implements from Java and Flores: A history of the discoveries

In 1970, Verhoeven and Maringer found stone implements on the surface of Mengeruda (an area including the sites Boaleza, Lembahmenge and Matamenge) and Ola Bula on Flores, which were similar to those found in Sangiran by von Koenigswald and Ghosh on Java. This, among other things, led von Koenigswald and Ghosh to compare the findings from Flores with those from Java, the Ngebung site. They thought that the Stegodon fossil from Mengeruda was the same species as the one from Java and, therefore, of a similar age. von Koenigswald and Ghosh were the first to accept that the artefact findings of Flores were in situ. They drew the right conclusions regarding the crossing to Flores by Homo erectus. And their ideas have now, almost 40 years later, been confirmed by the find of Homo floresiensis on Flores.
