Where: Indiana (39.4° N, 85.6° W: paleocoordinates 27.6° S, 51.7° W)
• coordinate based on political unit
• local area-level geographic resolution
When: Laurel Limestone Formation, Wenlock (433.4 - 427.4 Ma)
• "Laurel Limestone, units 2 and 3 of Frest (1975). The Tennessee equivalent, a part of the upper Maddox Member, Wayne Formation, is within the Kockelella ranuliformis and amsdeni conodont Zones as defined by Barrick and Klapper (1976) and Barrick (1983)."
• formation-level stratigraphic resolution
Environment/lithology: deep subtidal; shelly/skeletal grainstone and shelly/skeletal, argillaceous, cherty/siliceous wackestone
•SEP environmental call based on given information and knowledge of regional geology. Shallower than typical "deep subtidal" IMO, but doesn't really fit stated description of of shallow subtidal and is probably just below normal wave base for the most part.
