Bor Ukhaa hills, Shar Teg [HMNS-GIN] (Jurassic of Mongolia)

Also known as Shar-Teg, Shar Teeg, HMNS/MPC JPE

Where: Govi-Altay, Mongolia (44.1° N, 95.8° E: paleocoordinates 46.1° N, 97.9° E)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Ulan Malgait Formation, Tithonian (152.1 - 145.0 Ma)

• Dollman et al. (2018) argue that the age of the Ulan Malgait Formation is likely to be Oxfordian based on the shared presence of Shartegosuchus and Nominosuchus with the radiometrically-dated Shishigou Formation at Wucaiwan, China

• bed-level stratigraphic resolution

Environment/lithology: terrestrial; red mudstone and lenticular, fine-grained, coarse, blue sandstone

• "bluish fine-coarse sandstone layer (lens) intercalated in red mustone"

Size class: macrofossils
