Where: Japan (34.7° N, 133.1° E: paleocoordinates 15.5° N, 100.5° E)

• coordinate estimated from map

• small collection-level geographic resolution

When: Kawai Formation, Sakmarian (293.5 - 290.1 Ma)

• group of beds-level stratigraphic resolution

Environment/lithology: lithified limestone

• Limestone is strongly recrystallized by Cretaceous rhyolitic volcanic activity, making it difficult to determine the original lithofacies.

Size class: macrofossils
