説明
Stratigraphic ranges of four species Anadara amicula, A. ommaensis, Dosinia japonica and D. tomikawensis in the early Pleistocene Omma Formation were examined in order to evaluate their utility as regional stratigraphic indicators. The results indicate that D. japonica and D. tomikawensis can not be used as stratigraphic indices in the Omma Formation. On the other hand, the last occurrence (LO) of A. amicula and the first occurrence (FO) and LO of A. ommaensis are recognized within the depositional sequences 1, 2 and 6, respectively, in the middle part of the formation. These datums are dated by nannofossils at between 1.45 Ma (the age of the last appearance datum (LAD) of Helicosphaera sellii) and 1.24 Ma (the age of the LAD of Gephyrocapsa large) and may be used as regional biostratigraphic indicators.
