Where: Shannon County, Missouri (37.9° N, 90.8° W: paleocoordinates 22.8° S, 86.4° W)
• coordinate based on nearby landmark
• 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
Size class: macrofossils
Preservation: replaced with silica
