USGS Loc. 618 (Devonian of the United States)

Where: Pike County, Missouri (39.4° N, 90.9° W: paleocoordinates 27.6° S, 38.0° 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

Environment/lithology: shallow subtidal; lithified, dolomitic, gray, yellow, argillaceous lime mudstone and mudstone

• 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]
