Excavations at Sangiran revealed animal bones with cut marks, but no stone tools, leading some researchers to suggest that shell tools were used by H. erectus to butcher the animals. Experimental data tends to support these suppositions. If so, this may be a characteristic of H. erectus behavior that scientists have missed in the past.
Sangiran cave was excavated by R.G.H. von Koenigswald in 1936-1941, and later by S. Sartono and T. Jacob. The most recent studies have been joint Indonesia and Japanese studies led by Kildo Choi and Dubel Driwantoro.
