Signal Camp near Gasherbrum Gilga (Permian to of China)

Where: Xinjiang, China (35.9° N, 76.8° E: paleocoordinates 24.0° S, 60.1° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Shaksgam Formation, Roadian to Roadian (272.3 - 265.1 Ma)

• No stratigraphic details given in primary reference, but most likely from member 1 of the Shaksgam Formation (sparse brachiopods are also present higher in the formation). Presence of fusulinids Monodiexodina, Minojapanella wutuensis, Parafusulina japonica, and Boultonia suggests an early Guadalupian age for those units.

• bed-level stratigraphic resolution

Environment/lithology: open shallow subtidal; lithified, brown, gray, argillaceous limestone

Size class: macrofossils

Collected by A. Desio in 1929

• 1929 Italian expedition to the Karakorum
