| 概要 |
The Kuchinotsu group of west Kyushu is one of the important Lower Pleistocene strata in Japan for its geographic position near the western extremity of the Japanese islands and for the mammalian fossi...ls therein. Some molars of elephants were reported from this area, but their exact localities are uncertain. A remarkable bone bed was recently discovered in the upper part of the Kazusa formation of the Kuchinotsu group on the coast of Tsubami, northwest of Kazusa, Shimabara peninsula. It contains various bones of mammals, reptiles and pieces, of which many well-preserved antlers and bones belonging to three species of the Cervidae are recognized. As the first report of the palaeontological study of these fossils, this paper gives the general account of the stratigraphy of the Kuchinotsu group with special reference to the fossil bed and the description of a new species of Cervus (Rusa). Living species of Rusa are distributed mainly in various areas of southeastern Asia, and some fossil species are known to occur in the Villafranchian of northeast China and Java. The new occurrence of this subgenus from the Kuchinotsu group may imply the presence of a faunal connection between Japan and the continent at that time.続きを見る
