  • Columnals (PDF)
    2248 22482 2 4 V. INDEX OF COLUMNALS 8 Remarks: In this section the stratigraphic range given under the genus is the compiled range of all named species based solely on columnals assigned to the genus. It should be noted that this range may and often differs considerably from the range given under the same genus in Section I, because that range is based on species identified on cups or crowns. All other abbreviations and format follow that of Section I. Generic names followed by the type species are based on columnals. Genera, not followed by the type species, are based on cups and crowns as given in Section I. There are a number of unlisted columnal taxa from the literature that are indexed as genera recognized on cups and crowns. Bassler and Moodey (1943) did not index columnal taxa that were not new names or identified genera with the species unnamed. I have included some of the omissions of Bassler and Moodey, but have not made a search of the extensive literature specifically for the omitted citations because of time constraints. Many of these unlisted taxa are illustrated in the early state surveys of the eastern and central United States. Many of the columnal species assigned to genera based on cups or crowns are incorrect assignments. An uncertain, but significant, number of the columnal genera are synonyms of other columnal genera as they are based on different parts of the stem of a single taxon. Also a number of the columnal genera are synonyms of genera based on cups and crowns as they come from more distal parts of the stem not currently known to be associated with the cup or crown.

Jacquemin, Ph.D. Barry Milligan, Ph.D. Professor and Interim Dean of the Graduate School ABSTRACT Hoenig, Matthew Michael James. M.S. Department of Earth & Environmental Sciences, Wright State University, 2019. Chondrichthyan diversity within the Burlington-Keokuk Fish Bed of Southeast Iowa and Northwest Illinois (Mississippian: Osagean) Chondrichthyan remains occur in abundance within a thin layer of limestone at the top of the Burlington Limestone at the point of the contact with the overlying Keokuk Limestone. This layer of rock, the “Burlington-Keokuk Fish Bed,”1 is stratigraphically consistent and laterally extensive in exposures of the Burlington Limestone near its type section along the Iowa-Illinois border. Deposition of the fish bed occurred on the Burlington Continental Shelf carbonate ramp off the subtropical western coast of Laurussia during the Lower Carboniferous (Late Tournaisian; Osagean) due to a drop in sea level, although the specific mechanism(s) that concentrated the vertebrate fossils remain(s) unknown.

    A New Crinoid Fauna from the Harrodsburg Limestone (Mississippian) of Southern Indiana James R. Welch and N. Gary Lane Department of Geology- Indiana University, Bloomington, Indiana 47401 Abstract A recently discovered crinoid fauna from the lower three meters of the Harrodsburg Limestone (Osagian; Mississippian) along Judah Branch, southern Monroe County, Indiana, provides new evidence for the age relations of the Bono and Canton crinoid faunas in Indiana. Fossils from Bono, Lawrence County, and Canton, Washington County, were collected in the 19th century and these localities and their stratigraphic positions are not now known. The new site has yielded 15 species of crinoids, nine of which have been reported from Canton and three from Bono. Other species found include one known from the Ramp Creek Formation below the Harrodsburg and one also found in the Salem Limestone above. This new locality thus supports the hypothesis of Lane (1972) that the Canton fauna is of early Harrodsburg age and that the Bono fauna is slightly younger, but also of Harrodsburg age. The Judah Branch fauna is almost equally divided between inadunate crinoids (8 species) and camerates (6 species) with one flexible crinoid. The fauna is thus intermediate in terms of community evolution between the Canton fossils, dominated by inadunates, and the Bono crinoids, in which camerates are predominant. Introduction During the latter part of the 19th century a series of Mississippian age crinoid faunas were described from Indiana that were typically attributed to what was called a "Keokuk" age. This meant that these Indiana rocks and fossils were judged to be of the same age as the Keokuk Limestone, the uppermost formation of the Osagian series of the Mississippian, which crops out along the west side of the Illinois Basin.
