Where: Okinawa, Japan (26.3° N, 127.8° E: paleocoordinates 26.4° N, 127.7° E)
• coordinate estimated from map
• outcrop-level geographic resolution
When: Naha Formation (Ryukyu Group), Calabrian (1.8 - 0.8 Ma)
• Naha Formation ranges from the middle Calabrian (c. 1.3 Ma) to the Middle Pleistocene (c. 0.4 Ma), according to Yamamoto et al. (2006). Collection from lower beds of the formation, so Calabrian age assigned here.
• bed-level stratigraphic resolution
Environment/lithology: lagoonal or restricted shallow subtidal; poorly lithified, brown, white, calcareous grainstone and poorly lithified, brown, white limestone
Size class: macrofossils
Preservation: original aragonite
