Also known as Shar Teeg, Shar-Teg, Shar Teg

Where: Govi-Altay, Mongolia (44.1° N, 95.8° E: paleocoordinates 46.5° N, 98.3° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Shar Teg Formation, Late/Upper Jurassic (161.5 - 145.0 Ma)

• bed-level stratigraphic resolution

Environment/lithology: terrestrial; massive, gray, sandy siltstone and fine-grained, brown, calcareous sandstone

• "Sharply asymmetric cyclite; in the base there is a thin interbed (0.2-0.3 m) of brown calcareous fine-grained massive sandstones (up to 25 m) with interbeds of yellow siltstones. The upper parts of the layer are sandy grey massive siltstones. Pelecypods, insects, fish scales, seeds of Baisia, ferns, large bottlebrushes, pine-needles occur there. Total thickness is 28 m."
