Where: Japan (33.8° N, 130.5° E: paleocoordinates 40.3° N, 126.4° E)

• small collection-level geographic resolution

When: Waita Formation, Early/Lower Oligocene (33.9 - 28.4 Ma)

• STRATIGRAPHIC RELATIONS: From Waita Fm, which overlies the Honjo Fm of the Ashiya Gp. THICKNESS: From individual bed within formation that reaches 450 m in thickness. AGE: latest Early Oligocene according to Sakakura (2002) on the basis of calcareous nannoplankton and foraminifera (see Saito and Okada, 1984; Tsuchi et al., 1987). STRATIGRAPHIC POSITION: From middle of cycle W-2, at base of formation.

• bed-level stratigraphic resolution

Environment/lithology: offshore; poorly lithified mudstone

Size class: macrofossils

Collection methods: COLLECTOR: Presumably Sakakura (c. 2002). REPOSITORY: Possibly Kyoto University, Kyoto, Japan.
