| Research Abstract |
This research project aims to clarify the West Pacific marine biogeography and climate during the Middle Miocene climatic optimum(MMCO) based on the comparison of fossil molluscan faunas between Japan and SE Asia(Philippines and Indonesia). The results include that the species in common between Japan and SE Asia is very low in number(less than 5%), suggesting that each constitutes own biogeographic entities. Historical changes of geographic distribution of the Melongena lainei lineage, one of few species in common between Japan and SE Asia, were revealed. Paleo-temperature estimation based on the isotopic analysis of fossil bivalve during MMCO is a future work.
