Reticulariopsis-"Chonetes" n. sp. Comm., Yikewusu Fm., Xipingshan, NW Neimongol (Devonian of China)

Where: Nei Mongol, China (40.0° N, 105.0° E: paleocoordinates 23.3° S, 88.6° E)

• coordinate estimated from map

• local area-level geographic resolution

When: Yikewusu Formation, Eifelian (393.3 - 387.7 Ma)

• formation-level stratigraphic resolution

Environment/lithology: marine; limestone

• "The overall high diversity and presences of Kayseria, Skenidium, and Teichertina indicates BA 4-5 and relatively normal level of current activity." Further downsection occur calcareous sandstone and sandy conglomerate.
• "The shells occur in limestone as dominantly articulated specimens."

Collection methods: Table 18 (which includes specimen counts).
