Also known as TKRS 2
Where: Okinawa, Japan (26.4° N, 128.0° E: paleocoordinates 26.5° N, 127.7° 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; tuffaceous, gray, silty, sandy claystone
Size class: macrofossils
Preservation: original aragonite
Reposited in the USNM
Collection methods: quarrying,
• Collections held in USNM and UGSG repositories.
