Where: Kentucky (38.7° N, 83.8° W: paleocoordinates 27.3° S, 62.1° W)

• coordinate estimated from map

• hand sample-level geographic resolution

When: Bellevue Formation, Caradoc (458.4 - 449.5 Ma)

• Middle Maysvillian age. Sample #2 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: open shallow subtidal; lithified, shelly/skeletal packstone

Size classes: macrofossils, mesofossils

Preservation: cast, recrystallized, replaced with silica

Collection methods: bulk, mechanical,

• Bulk collection made in field and weighed, cleaned, prepped, and identified in lab at University of Cincinnati. Sample dimensions are 580.6 square-cm, weighing 3307 grams. At least 40 specimens counted; 37 individuals estimated (using half of total disarticulated specimens with two parts plus number of articulated/intact specimens). Fragmented trepostome bryozoans were counted as estimated percent cover using standard percent cover reference chart.
