Bumastus (Cybantyx) cuniculus Subassociation, Schoonmaker Quarry, Wauwatosa (Silurian to of the United States)

Also known as Reef 820

Where: Wisconsin (43.1° N, 88.0° W: paleocoordinates 24.3° S, 50.1° W)

• coordinate based on political unit

• outcrop-level geographic resolution

When: Racine Dolomite Formation, Wenlock to Wenlock (433.4 - 423.0 Ma)

• formation-level stratigraphic resolution

Environment/lithology: reef, buildup or bioherm; dolomite

• "assigned to BA 3 because it occurs in the upper, higher energy portion of carbonate buildups...found with the Coral Stromatoporoid and Pentamerid communityes...trilobites generally disarticulated, localized, and display preferred orientations [suggesting selective transport of moults]..."

•SEP environmental call based on given information and regional context
