Danville Locality (Vertebrates) (Carboniferous of the United States)

Also known as Oakwood Locality; Horseshoe Bend; Vermillion River; Illinois bonebed

Where: Vermilion County, Illinois (40.1° N, 87.8° W: paleocoordinates 4.9° S, 22.6° W)

• coordinate stated in text

• outcrop-level geographic resolution

When: Bond Formation (McLeansboro Group), Missourian (305.9 - 303.4 Ma)

• "We believe the vertebrates have been collected from a zone 10 feet or so below the Shoal Creek Member of the Bond Formation" (DeMar, 1970)

•Note: Shoal Creek Member is equivalent to Carthage Limestone Member, a name now used throughout the Illinois Basin for that lithological unit; see Jacobson (2002) A summary of references with changes in Pennsylvanian stratigraphic nomenclature at the ISGS since Bulletin 95.

• group of beds-level stratigraphic resolution

Environment/lithology: terrestrial; lithology not reported
