Racine Fm, SE Wisconsin, Franklin Quarry - Patzkowsky (Silurian to of the United States)

Where: Wisconsin (42.9° N, 88.0° W: paleocoordinates 25.2° S, 49.5° W)

• coordinate based on nearby landmark

When: Racine Formation, Wenlock to Wenlock (433.4 - 427.4 Ma)

Environment/lithology: reef, buildup or bioherm; lithified wackestone

• The major features of reefs in the Racine Formation include mound-like shapes, massive appearance, abundant fossils, and inclined flank beds. Carbonate mud and smaller bioclasts within reef deposits have been altered to a mosaic of dolomite crystals.

Size class: macrofossils
