This actually does not surprise me, because Homo erectus was a very skilled and sophisticated tool maker, more to follow . . .

Homo erectus on Java was already using shells of freshwater mussels as tools half a million years ago, and as a 'canvas' for an engraving. An international team of researchers, led by Leiden archaeologist Jose Joordens, published this discovery on 3 December in Nature. The discovery provides new insights into the evolution of human behavior.

I belief this is a report of the same discovery.
