Comment:	Age: The present specimens are not quite good enough to identify with confidence, considering the large number of North Pacific Tertiary oysters (especially in Sakhaline and Kamchatka). These specimens appear to be the same species that MacNeil identified from the Stepovak Formation as OSTREA TIGILIANA Slodkewitsch, an Eo-Oligocene species of the eastern USSR; NacNeil's specimens were far worse than yours and his identification must be considered questionable.
