Stratigraphy
| Geological group: | Odaira | ||||
| Stratigraphic resolution: | group of beds | ||||
| Stratigraphy comments: From the Odaira Formation (now raised to group rank). A late Early Miocene or possibly early Middle Miocene age is supported by the occurrence of calcareous nannofossils of CN3 or CN4 (Kano et al., 1993) and the presence of so-called Praeorbulina datum (ca. 16.1 Ma; Fig. 2, arrow) in the upper mudstone (Yoshida, 1992), along with a larger benthic foraminifera, Lepidocyclina (Nephrolepidina) japonica (Ibaraki and Kitamura, 2008) from the Odaira Group. | |||||
