Kurosawa, Minami-Akita-gun (Pleistocene of Japan)

Where: Japan (39.7° N, 140.2° E: paleocoordinates 39.9° N, 140.0° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Kitaura 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; poorly lithified, coarse-grained sandstone

Size class: macrofossils

Collection methods: Repository: Institute of Geology and Paleontology, Tohoku University, Sendai (IGPS)
