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 #3 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 414.5 square-cm, weighing 984 grams. At least 52 specimens counted; 51 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.
