  • Preliminary report on fossil ostracods from Mazukari shell mound in Minamichita Town, Aichi Prefecture, central Japan

抄録

This study reconstructed the paleoenvironment and paleo-water depth using the fossil ostracod assemblage from Mazukari shell mound in Minamichita Town, Aichi Prefecture, central Japan. Six species in 5 genera of ostracods were identified for the first time. The sand species were found to be most dominant with minor amount of inner muddy bay species. We estimated the paleo-water depth of approximately 12 m at approximately 9600 to 8600 cal BP based on modern ostracod data from Ise bay. Meanwhile, fossil ostracods were found in only 8 adult specimens, suggesting that the sea level curve was higher than in the previous study.
