Abstract
This report is a summary of 17 Proboscidean fossils discovered in the Japan Sea. Although most specimens were discovered off the coast of the San'in district (N35°10′-36°10′, E131°30′-132°), molars were also discovered off the coast of the Noto Peninsula and northeast of the Yamato ridge. These specimens were identified as Palaeoloxodon naumanni (MAKIYAMA), with one specimen being Mammnuthus primigenius (BLUMENBACH). 14C datings indicates their ages to be about 23, 000y.B.P.-38, 000y.B.P.It is impossible to consider that M. primigenius migrated from Hokkaido to Honshu over a land bridge in the last glacial period as the manifestation of mammal fauna for Quaternary geohistory. It is desirable to take into consideration that the remain's most likely drifted from China or that the animal crossed the channel by swimming.
