Huananochonetes-Xenostrophia Comm., Liujing Mbr., ADH 18 bulk, Hengxian, Guangxi (Devonian of China)

Where: Guangxi, China (22.7° N, 109.2° E: paleocoordinates 3.7° N, 125.6° E)

• coordinate based on political unit

• local area-level geographic resolution

When: Liujing Member (Yukiang Formation), Early/Lower Emsian (409.1 - 402.5 Ma)

• member-level stratigraphic resolution

Environment/lithology: marine; mudstone

• Shells commonly articulated and matrix muddy; authors therefore infer quiet water. High diversity, large body size, and absence of BA 4 and deeper taxa used to infer BA 3. See PBDB collections 25725-25731 for fauna of underlying beds.
• "muddy matrix"

Collection methods: Table 10 (which includes specimen counts). Bulk sample.
