Wucaiwan pterosaur (Jurassic of China)

Where: Xinjiang, China (45.2° N, 88.9° E: paleocoordinates 46.8° N, 91.3° E)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Middle Member (Shishugou Formation), Oxfordian (163.5 - 157.3 Ma)

• "The specimen is from 35 m below the T-1 marker tuff, which had been dated as

•161.2 6 0.2 Ma. Recalibration of the age of the Fish Canyon sanidine monitor mineral suggests that the age of the T-1 marker tuff should be adjusted 0.6% older. Thus, we regard its age as 162.2 plus/minus 0.2 Ma" (Andres et al 2014)

• bed-level stratigraphic resolution

Environment/lithology: alluvial fan; mudstone

Size class: macrofossils

Collected in 2001-2006; reposited in the IVPP

Collection methods: quarrying, surface (in situ),

• Collected from a 30 cm2 area separated from all other fossils by at least 10 m distance (Andres et al 2014)
