Where: Crawford County, Missouri (37.9° N, 91.2° W)
• Paleocoordinates: 15.6° N, 112.0° W (Wright 2013)
• outcrop-level geographic resolution
When: Eminence Formation, Trempealeauan (490.2 - 486.9 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
Preservation: original calcite, replaced with silica
