Iriki-toge (Pliocene of Japan)

Where: Japan (31.7° N, 130.5° E: paleocoordinates 32.0° N, 130.0° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Piacenzian (3.6 - 2.6 Ma)

• Slightly younger than the Shigehira flora at the Shiake locality (in the English summary), or a little earlier than the Shiake flora (in the text). Shigehira flora/Shiake Formation is Piacenzian, c. 3.0 Ma according to Momohara 2016, so this locality is also assigned a late Pliocene age.

• group of beds-level stratigraphic resolution

Environment/lithology: terrestrial; lithified siliciclastic sediments

Size class: macrofossils

Preservation: adpression

Collection methods: Repository: National Science Museum, Tokyo
