Where: Ohio (39.2° N, 84.6° W: paleocoordinates 26.5° S, 62.3° W)
• coordinate estimated from map
• hand sample-level geographic resolution
When: Miamitown Formation, Caradoc (458.4 - 449.5 Ma)
• Lower Maysvillian 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.
• bed-level stratigraphic resolution
Environment/lithology: deep subtidal shelf; lithified, shelly/skeletal packstone and lithified shale
Size classes: macrofossils, mesofossils
Preservation: mold/impression, recrystallized, original calcite, 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 1612.9 square-cm. At least 254 specimens counted; 171 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.
