Where: Chaiyaphum, Thailand (16.3° N, 102.0° E: paleocoordinates 20.8° N, 93.0° E)
• coordinate based on nearby landmark
• small collection-level geographic resolution
When: Nam Phong Formation, Norian to Norian (228.0 - 201.3 Ma)
• Nam Phong Formation has been dated as late Norian–Rhaetian on the basis of palynomorphs (Racey et al. 1996. Journal of Petroleum Geology 19: 5–40), although new data based on subsurface observations and palynology suggests that the formation should be split into lower and upper parts, and that the upper part may be Jurassic in age, and possibly even Late Jurassic (Racey & Goodall 2009. Geol. Soc. Lond. Spec. Publ. 315: 69-83). At outcrop, only Norian-Rhaetian palynomorphs have yet beeen recovered, and so a Late Triassic age is retained for the vertebrate remains at present
• bed-level stratigraphic resolution
Environment/lithology: fluvial-lacustrine; lithology not reported
Size class: macrofossils
