As shown in tables, the mammalian and plant fossils found in Hanaizumi seem to be similar to those of the mammoth fauna at Ku-Hsiang-Tung, China (Manchoukuo) and of Egota plant fossil bed found in Tokyo, respectively. Such similarity may suggest that the fossils found in Hanaizumi are of late Pleistocene age. Furthermore, it should be noticed here that several bone fragments which must be considered to be artificial cuts were found in the same bed.
