Where: Kentucky (38.6° N, 85.3° W: paleocoordinates 25.8° S, 59.1° W)
• coordinate estimated from map
• hand sample-level geographic resolution
When: Marble Hill Limestone Member (Lower Whitewater Formation), Ashgill (449.5 - 443.7 Ma)
• Middle Richmondian age. Sample #4 collected by Shuguang Mao. 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: sand shoal; lithified, dolomitic, shelly/skeletal, white grainstone
Size classes: macrofossils, mesofossils
Preservation: mold/impression, recrystallized, original calcite, replaced with calcite, replaced with dolomite
Collection methods: bulk, mechanical,
• Bulk collection made in field by Shuguang Mao and weighed, cleaned, prepped, and identified in lab at University of Cincinnati. Sample weighed 3769 g; outer surfaces samples, 116 square-inches (=748 square-cm). 97 specimens counted; 97 individuals estimated (using half of total disarticulated specimens with two parts plus number of articulated/intact specimens). Taxa counted using percent-coverage not included in this tally. Bivalves and brachiopods were counted as estimated percent cover using standard percent cover reference chart.
