Where: Japan (39.7° N, 140.3° E: paleocoordinates 39.9° N, 140.1° E)
• coordinate based on nearby landmark
• outcrop-level geographic resolution
When: Taya Formation, Calabrian (1.8 - 0.8 Ma)
• 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).
• group of beds-level stratigraphic resolution
Environment/lithology: coastal; unlithified, red sandstone
Size class: macrofossils
Collection methods: Repository: Institute of Geology and Paleontology, Tohoku University, Sendai (IGPS)
