Pinchuan, Baiyin City (Jurassic of China)

Also known as Baiyinosaurus type

Where: Gansu, China (36.7° N, 104.8° E: paleocoordinates 39.3° N, 108.8° E)

• coordinate stated in text

• outcrop-level geographic resolution

When: Straw-yellow Sandstone Member (Wangjiashan Formation), Late/Upper Bathonian (167.7 - 164.7 Ma)

• "Based on its megafossil plants and palynoflora, as well as the lacustrine invertebrate assemblage of the overlying Oil Shale Member, including conchostracans, charophytes, and bivalves, the Straw-yellow Sandstone Member of the Wangjiashan Formation is considered to be late Bathonian in age" (Li et al. 2024). Fossil from upper part of member.

• bed-level stratigraphic resolution

Environment/lithology: lacustrine deltaic; yellow sandstone

• "The Straw-yellow Sandstone Member of the Wangjiashan Formation was deposited mainly in a lake deltaic setting, and the succession is characterized by its straw-yellow colour. It changes gradually upward from coarse sandstones at the base to fine sands with interbedded red mudstones in the upper part." (Ning et al. 2024)

Size class: macrofossils
