Where: Japan (37.2° N, 139.2° E: paleocoordinates 29.2° N, 114.9° E)

• coordinate stated in text

• outcrop-level geographic resolution

When: Otori Formation, Wuchiapingian (259.9 - 254.2 Ma)

• Brachiopod fossils from the formation indicate a Late Permian (Wuchiapingian) age

•(this study). In terms of age and lithology, the Otori Formation probably correlates with the Upper Permian Maizuru Group of the Maizuru Belt, southwest Japan

• group of beds-level stratigraphic resolution

Environment/lithology: marine; lithified sandstone and lithified, black shale

Size class: macrofossils

Preservation: mold/impression

Collected by Tazawa and students in 1998-1999
