Where: Kanchanaburi, Thailand (14.0° N, 99.4° E: paleocoordinates 31.3° S, 99.8° E)
• coordinate based on nearby landmark
• outcrop-level geographic resolution
When: Rat Buri Formation, Roadian (272.3 - 268.8 Ma)
• The age of the Rat Buri fauna is problematic. "Rat Buri" limestones likely range in age from Kungurian through Capitanian to perhaps Wuchiapingian. Wordian fusulinids appear most common in other collections, but are not found in association with the brachiopod localities. The brachopod fauna is most similar to the Wordian Amb Formation of the Salt Range, in Pakistan, tentatively indicating a Wordian age.
• group of beds-level stratigraphic resolution
Environment/lithology: shallow subtidal; lithified, shelly/skeletal, silty, sandy limestone
