Phu Wiang 5A (Cretaceous of Thailand)

Also known as P.W.5A

Where: Khon Kaen, Thailand (16.7° N, 102.3° E: paleocoordinates 14.3° N, 110.9° E)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Sao Khua Formation (Khorat Group), Late/Upper Barremian (130.0 - 125.5 Ma)

• formerly considered Upper Jurassic

•Stratigraphy comments: Sao Khua Fm. was originally believed to be Early Cretaceous in age based on the vertebrate fossils by Buffetaut and Suteethorn (1999). More recently, the age has been constrained to the late Barremian based on non-marine bivalves by Tumpeesawan et al. (2010).

• bed-level stratigraphic resolution

Environment/lithology: terrestrial; red claystone and concretionary, calcareous conglomerate

• "red claystone with lime nodule conglomerate"
