Where: Okinawa, Japan (26.2° N, 127.8° E: paleocoordinates 26.3° N, 127.6° E)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Shinzato Formation (Shimajiri Group), Gelasian (2.6 - 1.8 Ma)

• The uppermost part of the Shimajiri Formation. Shinzato Formation correlated with planktonic foram zones PL5/6 and nannoplankton zones CN12b (upper part), 12c, and 12d by Ujiie (1994). This spans the latest Piacenzian and Gelasian, but a Gelasian age is assigned here following Sato et al. (1999) and Komatsubara et al. (2005).

• bed-level stratigraphic resolution

Environment/lithology: deep-water; poorly lithified, tuffaceous, gray, silty, sandy claystone

Size class: macrofossils

Preservation: original aragonite

Collected by F. Stearns MacNeil; reposited in the USNM
