Where: Japan (36.9° N, 137.0° E: paleocoordinates 37.2° N, 136.6° E)
• coordinate based on nearby landmark
• outcrop-level geographic resolution
When: Junicho Formation, Gelasian (2.6 - 1.8 Ma)
• From the "Himi beds" of Otuka, now the Junicho Formation. Junicho Formation is mostly Gelasian (uppermost part is Calabrian) on the basis of planktonic foram and diatom biostratigraphy, and tephrostratigraphy.
• group of beds-level stratigraphic resolution
Environment/lithology: marine; poorly lithified sandstone
Size class: macrofossils
