“…The occurrence of the brachiopod Mesolobus only below the Missourian has been known for a long time (Dunbar and Condra, 1932). Christopher et al (1990) demonstrated the occurrence of a distinct change in ostracode faunas at the Desmoinesian-Missourian boundary in the Appalachian basin. Tetractinomorph chaetetids were major reef builders during the Carboniferous, but declined suddenly in abundance at the end of the Westphalian (West and Archer, 1992).…”

Palynological Correlation of Major Pennsylvanian (Middle and Upper Carboniferous) Chronostratigraphic Boundaries in the Illinoi

Palynology provides chronostratigraphic correlations of Pennsylvanian (Middle and Upper Carboniferous) strata between the Illinois basin, which is the main focus of this study, and other coal basins in the UnitedStates, western Europe, and the Donets basin. Published reports and recent palynological analyses of coal samples from the Illinois basin, western part of the Midcontinent, and the Appalachian coal region were used in making the correlations. Correlations are made on the basis of first and last appearances and major changes in relative abundance of spore taxa. Studies of plant megafossils and faunas are discussed briefly in relation to some of the palynological correlations. Stratigraphers in the Midcontinent have considered the Lower Pennsylvanian Series equivalent to the Morrowan Stage, the Middle Pennsylvanian equivalent to the Atokan and Desmoinesian Stages, and the Upper Pennsylvanian equivalent to the Missourian and Virgilian Stages. I propose extending this nomenclature to the Illinois Basin. The chronostratigraphic classification of the Pennsylvanian System in the western part of the Midcontinent region was adopted by the Illinois State Geological Survey for the Illinois basin largely on the basis of studies of marine fossils. The precise position of the Morrowan−Atokan Stage boundary in Illinois is still not satisfactorily known. It generally has been correlated with the base of the Tradewater Formation but is herein correlated with the top of the Reynoldsburg Coal Bed, which is at the base of the formation. The top of the Morrowan occurs just above the base of the Tradewater Formation in western Kentucky and in the upper part of the Mansfield Formation in Indiana. I propose that the Atokan−Desmoinesian Stage boundary in Illinois correlates with the top of the Seville Limestone Member and equivalent limestone beds in Indiana and western Kentucky. The Desmoinesian−Missourian (Middle−Upper Pennsylvanian) boundary is correlated with the base of the Lake Creek Coal Member or, if that is not present, at the top of the Lonsdale Limestone Member in western Illinois and the top of the middle bench of the West Franklin Limestone Member in eastern Illinois and western Indiana. The Missourian−Virgilian Stage boundary has been correlated, in the absence of adequate palynological data, with strata a little below the Shumway Limestone Member as determined by fusulinid evidence. The Lower−Middle Pennsylvanian boundary in the Pennsylvanian stratotype in West Virginia proposed by the U.S. Geological Survey (USGS) is older than the Lower−Middle Pennsylvanian boundary of the Midcontinent. The latter correlates with the base of the Pounds Sandstone Member in Illinois and the Bee Spring Sandstone Member in western Kentucky.

“…The other dominating group of ostracodes is Bairdia McCoy, 1844 and its relatives. All these faunas are characterized by high species abundance (e.g., Cooper, 1946;Sohn, 1983;Christopher, Hoare, and Sturgeon, 1990;Sanchez de Posada and Bless, 1999;Sanchez de Posada and Fohrer, 2001).…”

The Pennsylvanian (Moscovian) Izvarino Section, Donets Basin, Ukraine: A Multidisciplinary Study on Microfacies, Biostratigraphy (Conodonts, Foraminifers, and Ostracodes), and Paleoecology

The mid-Moscovian Izvarino section, Donets Basin, eastern Ukraine, exhibits a complete sedimentological record of siliciclastics (sandstones, siltstones, and calcareous shales) with limestone intercalations and, rarely, coal seams. A multidisciplinary study including microfacies analysis, systematic paleontology (conodonts, fusulinoideans, and ostracodes), biostratigraphy, and paleoecology was focused on the limestones, from limestone L4 through limestone M1, and the adjacent marine shales. Based on sedimentology and fossil associations, the cyclic sediments of the Izvarino section were interpreted as entirely marine deposits of open- and shallow-marine, nearshore and offshore environments with variable terrigenous input.The well-preserved ostracode faunas are dominated by representatives of the families Amphissitidae, Hollinellidae, Healdiidae, Cavellinidae, and Paraparchitidae. The total fauna is 18 species, of which four are new: Hollinella (Hollinella) granuloba Fohrer, n. sp., Hollinella (Praehollinella) kamenka Fohrer, n. sp., Jordanites krasnodonensis Fohrer, n. sp., and Asturiella donbassica Fohrer, n. sp. The conodont fauna includes 21 species belonging to nine genera and includes one new species: Idiognathodus izvaricus Nemyrovska, n. sp. The conodont faunas are dominated by idiognathodontids. Representatives of Diplognathodus and Neognathodus play a subordinate role. A total of 56 fusulinoidean species referable to 20 genera has been identified; one is new: Eostaffella brazhnikovae Ueno, n. sp.Conodont and fusulinoidean biostratigraphy led to surprising differences in the age assignment of the Izvarino section and its correlation with the nearby Moscow Basin, Russia. The interval studied is lower Kashirian (Tsninskaya) to middle Kashirian (Narskaya), according to conodonts. It extends to the base of the Podolskian, however, according to fusulinoideans. This discrepancy is possibly related to problems in correlation of the type sections in the Moscow Basin. It calls for reexamination of the mid-Moscovian boundary interval and shows the limits of interbasinal correlations based on a single fossil group.

“…Two ostracod species that have been recovered from the basal muddy sandstone of the AA marine interval are identified as Kirkbyia bendensis (Harlton) and Kegelites wapanuckaensis (Harlton). Christopher (1990), in a study of ostracods from the Appalachian basin, described these two species only from the Kendrick Shale Member of the Breathitt Formation; they appear in no younger marine units. Unfortunately, Christopher (1990) did not examine any material older than the Kendrick, so these ostracods suggest only an upper limit on the age of the AA marine interval.…”

Unfortunately, Christopher (1990) did not examine any material older than the Kendrick, so these ostracods suggest only an upper limit on the age of the AA marine interval. However, I have collected samples of a fissile black shale from a marine unit identified as the Betsie Shale Member of the Breathitt Formation (Cobb et al, 1981) exposed along the Moun-tain Parkway in the Campton quadrangle.…”

Correlation chart of major and minor stratigraphic units in rocks of Pottsville and early Allegheny age between southern Ohio and northeastern and southeastern Kentucky. Palynology of coal beds for southern Ohio and Kentucky is from recent unpublished work of Robert M. Kosanke (U.S. Geological Survey, Denver, CO, written commun., 1992); palynology of the coal beds in the Gregoryville section at Stop 9 is by Cortland Eble. The Boggs limestone has been identified only in central Ohio, but is included here because it contains the earliest occurrence of fusulinids in Ohio and is a correlative of the Stoney Fork Member of the Breathitt Formation in Kentucky.
