Locality III, Eminence Formation, Crawford County, Missouri - Stinchcomb 1986 (Cambrian of the United States)

Where: Crawford County, Missouri (37.9° N, 91.2° W: paleocoordinates 22.5° S, 86.5° W)

• outcrop-level geographic resolution

When: Eminence Formation, Trempealeauan (501.0 - 485.4 Ma)

• The chert in which the fossils occur may or may not be in place stratigraphically. So, a rating of "A" through "F" indicates stratigraphi reliability with "A" = no question as to stratigraphic position of horizon and "F" = residual material of different ages. RATING: C

• formation-level stratigraphic resolution

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

• Strata are in pockets of the Ozark Uplift.

Preservation: original calcite, replaced with silica
