Also known as Reef 1431
Where: Grant County, Indiana (40.4° N, 85.8° W: paleocoordinates 28.8° S, 48.6° W)
• coordinate based on political unit
• outcrop-level geographic resolution
When: Pipe Creek Jr. Reef Member (Wabash Formation), Ludfordian (425.6 - 423.0 Ma)
• time subdivision given as Niagaran-Cayugan, or Wenlock-upper Ludlow. PJW: Was Silurian; however, Pipe Creek Jr. Reef is a subdivision of the Wabash formation. Simo & Lehman (2000: J. Sedimentary Research 70(4):937-951) place it as it middle Ludlow; as the Wabash is thought to go from Ludfordian - Pridoli, I have it as Ludfordian.
• member-level stratigraphic resolution
Environment/lithology: reef, buildup or bioherm; shelly/skeletal, gray, argillaceous grainstone and packstone
Size class: macrofossils
Collection methods: surface (in situ), chemical, peel or thin section,
• while not explicitly stated, it appears that fossils reported are those collected during field work in the quarry, not from state survey drill cores that were studied; fossils were collected in situ whenever possible, but the majority came from rock blasted from the SNW end of the quarry. This work was completed about one year after the quarry opened for business
