Early flakes from sozudai, Japan: are they man-made?

Some archeologists consider the lowest component of the Sozudai site to be evidence of a human occupation of southern Japan during the early Würm period. Others deny that the Sozudai objects are artifacts. With separate test procedures, flakes in the Sozudai assemblage were identified and compared to the standard developed by A. S. Barnes. These procedures indicate that flakes in the Sozudai assemblage are of human origin.
