Where: Laos (19.9° N, 102.1° E: paleocoordinates 11.8° S, 97.2° E)
• coordinate based on nearby landmark
• outcrop-level geographic resolution
When: Capitanian (264.3 - 259.5 Ma)
• Level 10 of Deprat, 1913. The greywacke bed was considered a little younger than the Lepidolina multiseptata fusulinid zone of the Sisophon Limestone, western Cambodia, by Deprat (1913). Based on faunal correlations, Waterhouse (1973; 1976) later considered Level 10 as partly correlative with Sisophon Member D (middle−late? Capitanian) of Ishii et al. (1969) where L. multiseptata persists from Member C.
