Ulan Malgait Mtn. [Ulan Malgait Fm., bed 4] [SMPE] (Jurassic of Mongolia)

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

Where: Govi-Altay, Mongolia (44.1° N, 95.8° E: paleocoordinates 46.0° N, 98.0° E)

• coordinate estimated from map

• outcrop-level geographic resolution

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

• bed-level stratigraphic resolution

Environment/lithology: terrestrial; conglomeratic siltstone and massive, fine-grained sandstone

• "Cyclite; in the base there are siltstones with an admixture of gravel and sandy material (0.7 m) with bivalves, replaced by fine-grained to gravel-like massive sandstones (0.4 m). Above are variegated siltstones with an admixture of gravel (1.5 m). Gastropods, bivalves, ostracods, fishes, sauropods and oogonia of charophytes occur there. The bone-bearing horizon is overlapped by fine-grained massive sandstones, on which variegated silststones with carbonate varices occur. Total thickness 6 m."
