• Late Richmondian age. Sample #1 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. C6.
• bed-level stratigraphic resolution
Environment/lithology: lagoonal or restricted shallow subtidal; lithified, pyritic, shelly/skeletal, gray wackestone and lithified, pyritic, shelly/skeletal, gray packstone
Size classes: macrofossils, mesofossils, microfossils
Preservation: cast, mold/impression, recrystallized, original calcite, replaced with calcite, replaced with phosphate
Collection methods: bulk, mechanical,
• Bulk collection made in field and weighed, cleaned, prepped, and identified in lab at University of Cincinnati. Sample weighed 2.7741 Kg. 41 specimens counted; 30 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. Bryozoans and ostracodes were counted as estimated percent cover using standard percent cover reference chart.
