| Research Abstract |
Based on taxonomic and stratigraphic analyses,earliest fossilrecord of the glycymeridid bivalve Glycymeris vestita is determined to be specimens from the Nojima Formation of the Kazusa Group(2 Ma).Earliest fossil record of the limid bivalve,Acesta goliath is found to be specimens from the Miyata and Kasamori formations(0.6-0.5Ma),and the same age is inferred for A.smithi from the earliest record from the Kasamori Formation.
