Also known as Hannah Creek

Where: Indiana (39.6° N, 84.9° W: paleocoordinates 25.2° S, 58.2° W)

• coordinate estimated from map

• hand sample-level geographic resolution

When: Waynesville Formation, Ashgill (449.5 - 443.7 Ma)

• Middle Richmondian 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: offshore shelf; lithified, burrowed, pyritic, shelly/skeletal claystone and lithified, shelly/skeletal wackestone

Size classes: macrofossils, mesofossils, microfossils

Preservation: cast, mold/impression, adpression, trace, recrystallized, coalified, original calcite, original chitin, original carbon, replaced with calcite, replaced with pyrite

Collection methods: bulk, mechanical,

• Bulk collection made in field and weighed, cleaned, prepped, and identified in lab at University of Cincinnati. Sample dimensions are 2212 cubic-cm. 94 specimens counted; 61 individuals estimated (using half of total disarticulated specimens with two parts plus number of articulated/intact specimens). Trepostome bryozoans and fragmented trilobites were counted as estimated percent cover using standard percent cover reference chart.
