Khermin Tsav I, Lower White Beds [HMNS-GIN] (Cretaceous to of Mongolia)

Also known as Khermeen Tsav

Where: Omnogov, Mongolia (43.5° N, 99.8° E: paleocoordinates 43.8° N, 90.4° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Baynshire Formation, Cenomanian to Cenomanian (100.5 - 83.6 Ma)

• Lower White Beds (geological age unknown)

• group of beds-level stratigraphic resolution

Environment/lithology: eolian; sandstone and paleosol/pedogenic mudstone

• "predominantly eolian and fluvio-lacustrine deposits"
• "The Lower White Beds have lithology mainly consisting of sandstone layers with cross-stratification, and intercalations of mudstone beds with paleosol. The thickness of the Lower White Beds is about 23 m. Paleocurrent direction based on trough cross-stratification on sandstone layer of the Beds mainly indicates NW (280 degree, standard deviation = 4.17, N = 12)."

Size classes: macrofossils, mesofossils
