Locality M-10, Eminence Formation, Iron County, Missouri - Stinchcomb 1986 (Cambrian of the United States)

Where: Shannon County, Missouri (37.6° N, 91.1° W: paleocoordinates 22.6° S, 86.8° W)

• outcrop-level geographic resolution

When: Pachendoceras zone, 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: D

• 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
