Huai Dam Chum tracksite (Cretaceous to of Thailand)

Also known as Lao Nat

Where: Nakhon Phanom, Thailand (17.7° N, 104.4° E: paleocoordinates 17.5° N, 110.9° E)

• coordinate stated in text

• outcrop-level geographic resolution

When: Khok Kruat Formation (Khorat Group), Aptian to Aptian (125.0 - 100.5 Ma)

• bed-level stratigraphic resolution

Environment/lithology: terrestrial; sandstone and mudstone

• "The outcrop, which consists mainly of very-fine-grained sandstone, is present along route 212. Approximately 600 tracks occur in thin mudstone layer of the northern part of the outcrop at this site. On the footprint-bearing thin mudstone layer, current-ripple marks that show a NW flow direction and mud cracks are overprinted by footprints."
