Where: Washington County, Ohio (38.8° N, 84.2° W: paleocoordinates 27.0° S, 62.3° W)

• coordinate estimated from map

• hand sample-level geographic resolution

When: Climacograptus pygmaeus graptolite zone, Kope Formation, Edenian (451.0 - 450.2 Ma)

• Middle Edenian age. Sample #5 collected. Details on stratigraphy and sedimentation (lithology), and additional details of gastropod and bivalve fauna are included from Novack-Gottshall and Miller (2003) [PBDB reference #18186] and field notes.

• bed-level stratigraphic resolution

Environment/lithology: offshore shelf; lithified, graded, shelly/skeletal wackestone and lithified shale

Size classes: macrofossils, mesofossils

Preservation: mold/impression, recrystallized, original calcite, original carbon, replaced with calcite

Collection methods: bulk, mechanical,

• Bulk collection made in field and weighed, cleaned, prepped, and identified in lab at University of Cincinnati. Sample dimensions are 448.4 square-cm, weighing 893 grams. At least 41 specimens counted; 33 individuals estimated (using half of total disarticulated specimens with two parts plus number of articulated/intact specimens). Fragmented trepostome bryozoans, crinoid columnals, and fragmented trilobites were counted as estimated percent cover using standard percent cover reference chart.
