Time
Period: Quaternary Epoch: Pleistocene
Stage: Calabrian 10 m.y. bin: Cenozoic 6
Key time interval: Calabrian
Age range of interval: 1.8 - 0.774 m.y. ago
Stratigraphy
Formation:Taya
Stratigraphic resolution:group of beds
Stratigraphy comments: Sandstone beds underlying the Sandy shale beds. Hatai says that the Sandy shale beds "probably correspond to a part of the Wakimoto sandy shale beds of Oga Peninsula," so these units are either part of or underlying the Wakimoto Formation. Taya beds contain same foraminifera association as the Kitaura beds, which are Calabrian in age and underlie the Wakimoto Formation (Ozawa & Kamiya, 2005).
