Where: Nepal (29.5° N, 83.1° E: paleocoordinates 50.3° S, 62.0° E)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Pija Member (Senja Formation), Changhsingian (254.2 - 252.2 Ma)

• Correlation is difficult, but stratigraphic position and correlation of underlying Nangung Formation suggests a Changhsingian age. 7 m thick. Krotovia arcuata Subzone.

• group of beds-level stratigraphic resolution

Environment/lithology: marine; lithified, yellow, silty limestone and lithified siltstone

• Calcareous silty gold-weathering beds, and some intervening siltstone;.

Size class: macrofossils

Preservation: cast, original calcite

Collection methods: Some collections were of individual specimens, others as large as possible under the circumstances, with a few localities represented by rock weighing more than 50 kg. Most collections were made from just over 50 measured sections, and are under good stratigraphic control.
