Wulanwulaco and Wangshengshan, Hoxhil, China (Jurassic to of China)

Where: Qinghai, China (34.8° N, 91.0° E: paleocoordinates 25.4° N, 88.0° E)

• coordinate estimated from map

• local area-level geographic resolution

When: Yanshiping Group, Bathonian to Bathonian (168.3 - 152.1 Ma)

• group-level stratigraphic resolution

Environment/lithology: shallow subtidal; lithified, shelly/skeletal limestone

• The bivalves were probably buried in the inner sublittoral zone or on a beach near the lower to moderate-energy habitats in which they lived. The few non-marine bivalves are regarded as allochthonous and were probably carried onto the beach or into the inner sublittoral zone from a nearby fresh or brackish environment.
• bioclastic limestone

Size class: macrofossils

Preservation: cast, mold/impression, trace

Collection methods: Focus on bivalves.
