Tanagura, Higasi-Sirakawa-gun (Miocene of Japan)

Where: Japan (37.0° N, 140.4° E: paleocoordinates 38.6° N, 138.6° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Kubota Formation, Tortonian (11.6 - 7.2 Ma)

• From the "Tanagura beds", which now appears to be the Kubota Formation by comparison of the lithological descriptions. Kubota Formation dated to early Tortonian on the basis of magnetostratigraphy, fission track and K/Ar ages, and diatom, radiolarian, and planktonic foraminiferal biostratigraphy (Hayashi et al., 2002).

• group of beds-level stratigraphic resolution

Environment/lithology: marine; sandstone

Size class: macrofossils
