Kham-keut, at Kham-mon (Schwagerina princeps horizon) (Permian to of Laos)

Where: Laos (18.3° N, 105.0° E: paleocoordinates 16.7° S, 101.9° E)

• coordinate based on political unit

• local area-level geographic resolution

When: Asselian to Asselian (298.9 - 290.1 Ma)

• Waterhouse (1973) considered the fusulinid and brachiopod fauna to indicate an Asselian age, but the region is faulted and folded, making age determination difficult given the poor geographic resolution of sample. Archbold (1981) mentioned Kham-keut as "Asselian to early Sakmarian."

• group of beds-level stratigraphic resolution

Environment/lithology: lithified limestone

Size class: macrofossils
