I-U-E community from Longmenshan Area (Devonian of China)

Where: Sichuan, China (32.3° N, 104.5° E: paleocoordinates 6.5° S, 122.2° E)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Guanwushan Formation, Givetian (387.7 - 382.7 Ma)

• bed-level stratigraphic resolution

Environment/lithology: perireef or subreef; shale and marl

• The I-U-E community is overlapped by C-H composite reef.
• The I-U-E community occurs within alternating marls and calcareous shale in the middle part of the Guanwushan Formation. The stratum is only 2 m thick in total.
