Kabi, Ziyun County (Permian of China)

Where: Guizhou, China (25.6° N, 106.2° E: paleocoordinates 4.7° S, 97.1° E)

• coordinate stated in text

• outcrop-level geographic resolution

When: Houziguan Formation, Wordian (268.8 - 265.1 Ma)

• Member XII, at the top of the Houziguan Formation, which is stratigraphically equal to the top of the Maokou Formation in the platform interior. The ammonoid collection presumably comes from a little below Bed 29 in the Shaiwa section (Sec. IV-IV’), but still correlates with the Waagenoceras sp. representatives of the Waagenoceras sp.-Propinacoceras beyrichi Zone, which is Wordian in age biostratigraphically.

• group of beds-level stratigraphic resolution

Environment/lithology: basinal (); lithified claystone

Size class: macrofossils

Reposited in the NIGPAS
