Also known as Was: Russel Branch, sample 1 (RB1), Waynesville Formation, St. Marys, IN
Where: Indiana (39.4° N, 85.1° W: paleocoordinates 25.3° S, 58.5° W)
• coordinate estimated from map
• hand sample-level geographic resolution
When: Aphelognathus grandis conodont zone, Waynesville Formation, Richmondian (449.5 - 443.7 Ma)
• Middle 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.
• 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 phosphate, 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 weighed 3.744 Kg. 117 specimens counted; 57 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.
