Where: Vietnam (21.1° N, 104.7° E: paleocoordinates 16.4° S, 96.9° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Cisuralian (298.9 - 273.0 Ma)

• Some species listed as coming from Uralian limestones or the horizon with schwagerines (Schwagerina princeps), but range is unclear. Grant (1976) felt that one species belonged to Bilotina, possibly suggesting a younger age.

• group of beds-level stratigraphic resolution

Environment/lithology: lithified limestone

Size class: macrofossils
