Where: Ningxia, China (38.1° N, 106.7° E: paleocoordinates 41.0° N, 111.1° E)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Middle Jurassic (174.7 - 161.5 Ma)

• Probably from Member 4 (of 5) in the upper part of the Yanan Formation (Xu et al. 2018), which is now dated to the Aalenian (Zhang et al. 2021), but You et al. (2019) have argued that it is more likely to be from the Zhiluo Formation, which is more likely to be Bathonian-Callovian

• bed-level stratigraphic resolution

Environment/lithology: fluvial-lacustrine; massive, brown, gray, yellow mudstone

Size class: macrofossils

Collected in 2005 onwards; reposited in the IVPP
