Where: Pike County, Missouri (39.4° N, 91.1° W: paleocoordinates 27.5° S, 38.1° W)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Louisiana Limestone Formation, Late/Upper Famennian (364.7 - 360.7 Ma)

• Originally listed as Kinderhookian (Mississippian) age, changed by Sando et al. 1969. [JA: Siphonodella praesulcata Zone, i.e., latest Famennian, according to Chauffe and Nichols 1995]

• bed-level stratigraphic resolution

• typically composed of dense blue-gray limestone beds separated by brown dolomitic clay partings, includes a few beds of yellow-brown calcareous mudstone or soft argillaceous limestone. [dense limestone here is characterized as lithographic = lime mudstone to me]
