| Abstract;S. shinshuensis, S. aurorae, M. protomammonteus, S. orientalis, P. naumanni and M. primigenius appeared successively during the Pio-Pleistocene in Japan. These proboscidean species take an important role in considering the origin and faunal succession of mammal fossils in Japan. The origin and faunal succession have been widely discussed by several authors, but most of these studies have been made through comparison between a faunal list of a given site and that of a specific region in the Asian Continent. We considered that this limited approach is an inadequate basis upon which to discuss meaningfully about the topic addressed in this paper, and therefore we include most papers that have described proboscidean fossils in China, Taiwan and Japan. A database that included 333 Chinese sites, 26 Taiwanese sites and 285 Japanese sites was prepared from these papers, and was used to produce a distribution map of proboscidean fossils in the Plio-Pleistocene. Field surveys and studies of museum materials have been made in these countries. These studies both provided new and supplementary information and clarified and corrected errors in the published literature. The sequence of the Plio-Pleistocene proboscidean fossils in China was correlated with the biozones of Japanese proboscidean fossils. A comparison of the proboscidean horizons of northern China with the biozones of the Japanese proboscideans showed the horizons of M. primigenius, P. naumanni and S. orientalis to be in agreement. These results of the distribution maps and the comparison with the biozones of Japanese proboscideans indicate that P. naumanni and S. orientalis originated in China. M. primigenius migrated to Japan from the northern region of mainland Asia. S. aurorae and M. protomammonteus are considered to be endemic species that have their ancestors in China. (author abst.) |
