Phu Wiang 1A, Phu Pratu Teema (Cretaceous of Thailand)

Also known as Phu Phratoo Teema

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).

• member-level stratigraphic resolution

Environment/lithology: "channel"; fine-grained, green sandstone and lithified, gray, green, red siltstone

• "[facies 1] can be interpreted as channel deposits...[facies 2] interpreted as floodplain deposits." (Buffetaut & Suteethorn, 1989)
• "resistant red, grey and green siltstones" (Martin, 1999). "fine-grained greenish sandstones [facies 1]...red or variegated siltstones [facies 2]." (Buffetaut & Suteethorn, 1989)

Size classes: macrofossils, mesofossils
