Fauna from the Blocher Member, New Albany Shale (Upper Devonian) of Indiana (Carboniferous of the United States)

Where: Indiana (38.7° N, 85.7° W: paleocoordinates 27.0° S, 33.9° W)

• coordinate based on political unit

• local area-level geographic resolution

When: To I zone, Blocher Member (New Albany Shale Formation), Kinderhookian (358.9 - 352.0 Ma)

• The faunal zone "To I" refers to the German Upper Devonian and is based on conodonts and ammonites. This author's revised Blocher Member contains the lower few feet of Campbell's Blackiston Formation.

• member-level stratigraphic resolution

Environment/lithology: shallow subtidal; concretionary, dolomitic, gray, calcareous shale and limestone

• The New Albany Shale in Indiana was deposited in a shallow marine environment under reducing conditions that were caused by lack of water circulation.
• calcareous to dolomitic, brownish-black carbon-rich, laminated, fissile, pyritic shale; weathers light gray with brown and yellow stains; lower few feet have calcite present; lenticular, petroliferous, light to dark gray, micritic dolomite and rare calcitic dolomite beds are present (up to one foot thick); dolomicritic concretions (reaching 1 foot thick, 3 feet diameter); lenticular, cross statified, dolomitic quartz sandstone and quartz sandy dolomite present 4 to 10 feet above the base of the new albany; non-persistant beds of light olive-gray shale; dark carbonate shales with dolomite or calcite grains

Collection methods: faunal data includes information compiled from Kindle, 1901; Huddle, 1933; and Campbell, 1946 in addition to field collections.

Taxonomic list

• The list has questionable occurrences of the cephalopods Werneroceras wabashensis, Manticoceras kindlei, Maticoceras delphiensis, and Manticoceras unduloconstrictum that were compiled from Kindle, 1901; Huddle, 1933; and Campbell, 1946. These fauna were given solid indentifications but it was indicated that it was questionable that the fauna were found within the Blocher and they are, therefore, not included with the taxonomic list with this record. The list also indicates that burrows were found within the member.
