Geography
Country:United States State/province:Indiana County:Grant
Coordinates: 40.4° North, 85.8° West (view map)
Paleocoordinates:28.8° South, 48.6° West
Basis of coordinate:based on political unit
Geographic resolution:outcrop
Time
Period:Silurian Epoch:Ludlow
Stage:Ludfordian 10 m.y. bin:Silurian 2
Key time interval:Ludfordian
Age range of interval:425.60000 - 423.00000 m.y. ago
Stratigraphy
Formation:Wabash Member:Pipe Creek Jr. Reef
Stratigraphic resolution:member
Stratigraphy comments: 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.
Lithology and environment
Primary lithology:shelly/skeletal,gray argillaceous grainstone
Secondary lithology: packstone
Lithology description: fossils were collected from the flank beds of the reef; five lithologies were recognized: limestone, swirly limestone, dolomite and dolomitic limestone, silty mudstone, and interreef siltstone. 97% of the beds in the measured sections were limestone or swirly limestone. limestone described as white to gray, coarse-grained, and highly fossiliferous. swirly limestone described as argillaceous, characterized by milky while sparry calcite mixed with stringers and blobs of green silt to clay sized particles, medium to coarse-grained gray limestone and echinodermal debris
Environment:reef, buildup or bioherm
Taphonomy
Modes of preservation:body
Size of fossils:macrofossils
Collection methods and comments
Collection methods:surface (in situ),chemical,peel or thin section,field collection
Reason for describing collection:paleoecologic analysis
Collection method comments: 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
