Where: Thailand (8.5° N, 98.5° E: paleocoordinates 32.1° S, 106.3° E)
• coordinate based on nearby landmark
• outcrop-level geographic resolution
When: Rat Buri Formation, Roadian (272.3 - 268.8 Ma)
• Brachiopod-bearing bed is visible in the cliff wall about 30 feet above the ground but is inaccessible. Blocks containing fossils have fallen from the cliff and lie along the base. 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.
