Subsurface Facies Analysis of the Devonian Berea Sandstone in Southeastern Ohio
SUBSURFACE FACIES ANALYSIS OF THE DEVONIAN BEREA SANDSTONE IN SOUTHEASTERN OHIO William T. Garnes A Thesis Submitted to the Graduate College of Bowling Green State University in partial fulfillment of the requirements for the degree of MASTER OF SCIENCE December 2014 Committee: James Evans, Advisor Jeffrey Snyder Charles Onasch ii ABSTRACT James Evans, Advisor The Devonian Berea Sandstone is an internally complex, heterogeneous unit that appears prominently both in outcrop and subsurface in Ohio. While the unit is clearly deltaic in outcrops in northeastern Ohio, its depositional setting is more problematic in southeastern Ohio where it is only found in the subsurface. The goal of this project was to search for evidence of a barrier island/inlet channel depositional environment for the Berea Sandstone to assess whether the Berea Sandstone was deposited under conditions in southeastern Ohio unique from northeastern Ohio. This project involved looking at cores from 5 wells: 3426 (Athens Co.), 3425 (Meigs Co.), 3253 (Athens Co.), 3252 (Athens Co.), and 3251 (Athens Co.) In cores, the Berea Sandstone ranges from 2 to 10 m (8-32 ft) thick, with an average thickness of 6.3 m (20.7 ft). Core descriptions involved hand specimens, thin section descriptions, and core photography. In addition to these 5 wells, the gamma ray logs from 13 wells were used to interpret the architecture and lithologies of the Berea Sandstone in Athens Co. and Meigs Co. as well as surrounding Vinton, Washington, and Morgan counties. Analysis from this study shows evidence of deltaic lobe progradation, abandonment, and re-working. Evidence of interdistributary bays with shallow sub-tidal environments, as well as large sand bodies, is also present. -

CONODONTS OF THE MOJCZA LIMESTONE JERZY DZIK Dzik, J. 1994. Conodonts of the M6jcza Limestone. -In: J. Dzik, E. Olemp ska, and A. Pisera 1994. Ordovician carbonate platform ecosystem of the Holy Cross Moun tains. Palaeontologia Polonica 53, 43-128. The Ordovician organodetrital limestones and marls studied in outcrops at M6jcza and Miedzygorz, Holy Cross Mts, Poland, contains a record of the evolution of local conodont faunas from the latest Arenig (Early Kundan, Lenodus variabilis Zone) to the Ashgill (Amorphognathus ordovicicus Zone), with a single larger hiatus corre sponding to the subzones from Eop/acognathus pseudop/anu s to E. reclinatu s. The conodont fauna is Baltic in general appearance but cold water genera , like Sagitto dontina, Scabbardella, and Hamarodus, as well as those of Welsh or Chinese af finities, like Comp/exodus, Phragmodus, and Rhodesognathu s are dominant in par ticular parts of the section while others common in the Baltic region, like Periodon , Eop/acognathus, and Sca/pellodus are extremely rare. Most of the lineages continue to occur throughout most of the section enabling quantitative studies on their phyletic evolut ion. Apparatuses of sixty seven species of thirty six genera are described and illustrated. Phyletic evolution of Ba/toniodus, Amorphognathu s, Comp/exodus, and Pygodus is biometrically documented. Element s of apparatu ses are homolog ized and the standard notation system is applied to all of them. Acodontidae fam. n., Drepa nodus kie/censis sp. n., and D. santacrucensis sp. n. are proposed .

GEOLOGICAL SURVEY OF OHIO. VOL. I.—PART II. PALÆONTOLOGY. SECTION II. DESCRIPTIONS OF FOSSIL FISHES. BY J. S. NEWBERRY. Digital version copyrighted ©2012 by Don Chesnut. THE CLASSIFICATION AND GEOLOGICAL DISTRIBUTION OF OUR FOSSIL FISHES. So little is generally known in regard to American fossil fishes, that I have thought the notes which I now give upon some of them would be more interesting and intelligible if those into whose hands they will fall could have a more comprehensive view of this branch of palæontology than they afford. I shall therefore preface the descriptions which follow with a few words on the geological distribution of our Palæozoic fishes, and on the relations which they sustain to fossil forms found in other countries, and to living fishes. This seems the more necessary, as no summary of what is known of our fossil fishes has ever been given, and the literature of the subject is so scattered through scientific journals and the proceedings of learned societies, as to be practically inaccessible to most of those who will be readers of this report. I. THE ZOOLOGICAL RELATIONS OF OUR FOSSIL FISHES. To the common observer, the class of Fishes seems to be well defined and quite distin ct from all the other groups o f vertebrate animals; but the comparative anatomist finds in certain unusual and aberrant forms peculiarities of structure which link the Fishes to the Invertebrates below and Amphibians above, in such a way as to render it difficult, if not impossible, to draw the lines sharply between these great groups. -

Early Triassic marine fishes and reptiles Fish nodule therefore are key proxies in reconstructing the ecosystem recovery process after the end-Permian mass extinc- Redox condition tion. In South China, the Early Triassic Jurong fish fauna is the earliest marine vertebrate assemblage inthe Ecosystem recovery period. It is constrained as mid-late Smithian in age based on both conodont biostratigraphy and carbon Taphonomy isotopic correlations. The Jurong fishes are all preserved in calcareous nodules embedded in black shaleofthe Lower Triassic Lower Qinglong Formation, and the fauna comprises at least three genera of Paraseminotidae and Perleididae. The phosphatic fish bodies often show exceptionally preserved interior structures, including net- work structures of possible organ walls and cartilages. Microanalysis reveals the well-preserved micro-structures (i.e. collagen layers) of teleost scales and fish fins. -
Annual Meeting 1998
PALAEONTOLOGICAL ASSOCIATION 42nd Annual Meeting University of Portsmouth 16-19 December 1996 ABSTRACTS and PROGRAMME The apparatus architecture of prioniodontids Stephanie Barrett Geology Department, University of Leicester, University Road, Leicester LE1 7RH, UK e-mail: [email protected] Conodonts are among the most prolific fossils of the Palaeozoic, but it has taken more than 130 years to understand the phylogenetic position of the group, and the form and function of its fossilized feeding apparatus. Prioniodontids were the first conodonts to develop a complex, integrated feeding apparatus. They dominated the early Ordovician radiation of conodonts, before the ozarkodinids and prioniodinids diversified. Until recently the reconstruction of the feeding apparatuses of all three of these important conodont orders relied mainly on natural assemblages of the ozarkodinids. The reliability of this approach is questionable, but in the absence of direct information it served as a working hypothesis. In 1990, fossilized bedding plane assemblages of Promissum pulchrum, a late Ordovician prioniodontid, were described. These were the first natural assemblages to provide information about the architecture of prioniodontid feeding apparatus, and showed significant differences from the ozarkodinid plan. The recent discovery of natural assemblages of Phragmodus inflexus, a mid Ordovician prioniodontid with an apparatus comparable with the ozarkodinid plan, has added new, contradictory evidence. Work is now in progress to try and determine whether the feeding apparatus of Phragmodus or that of Promissum pulchrum is most appropriate for reconstructing the feeding apparatuses of other prioniodontids. This work will assess whether Promissum pulchrum is an atypical prioniodontid, or whether prioniodontids, as currently conceived, are polyphyletic. -

Paseo de Ronda 47, 15011 A Coruña (Spain). [email protected] ABSTRACT A stratigraphic description of the Devonian and Carboniferous pre-Variscan rocks of the Pyrenees is presented. The successions are grouped into sedimentary domains that replace the “facies areas” proposed by previous authors for areas with homogeneous stratigraphy. The description of the sedimentary filling is divided into temporal intervals, where the previous stratigraphic correlation, based on lithological criteria, is supplemented by faunal data, especially conodont findings. A simple palaeogeographic model of the sedimentation during the Upper Palaeozoic and data related to southern boundary between the Pyrenean basin and the Cantabro-Ebroian Massif are discussed. Keywords: Devonian, Carboniferous, conodonts, Pyrenees, stratigraphy. RESUMEN Se ha realizado una descripción estratigráfica de las rocas devónicas y carboníferas pre- variscas de los Pirineos. Las sucesiones son agrupadas en dominios sedimentarios que sustituyen a las “áreas de facies” propuestas por los autores previos para zonas con una estratigrafía homogénea. La descripción del relleno sedimentario está dividida en intervalos de tiempo, donde la correlación estratigráfica basada en criterios litológicos está incrementada por los datos faunísticos, sobre todo los hallazgos de conodontos. -
Jujuy Province, Argentina
Updated stratigraphy and biostratigraphy of the Sierra de Cajas / Espinazo del Diablo (Upper Cambrian – Lower Arenig), Jujuy province, Argentina Guillermo F. Aceñolaza1 1 INSUGEO – Facultad de Ciencias Naturales e I.M.L., Universidad Nacional de Tucumán, Miguel Lillo 205, 4000 Tucumán. E-mail: [email protected] Palabras clave: Estratigrafía. Bioestratigrafía. Cambro-Ordovícico. Cajas. Jujuy. Argentina. Key Words: Stratigraphy. Biostratigraphy. Cambrian-Ordovician. Cajas. Jujuy. Argentina. Introduction The Sierra de Cajas / Espinazo del Diablo is a classical locality for the Cambro- Ordovician transition in the Cordillera Oriental of Jujuy province, NW Argentina (Fig. 1). While Cambro-Ordovician strata characterize the Sierra de Cajas, Cretaceous/Tertiary sandstones and shales westwards flanked by highly fossiliferous Arenig shales and sandstones are displayed in the Espinazo del Diablo. The first references to the geological aspects of the area start in colonial times, with early data during the XVII century referring to the mineralization associated to the Aguilar Granite. Lead and zinc sedex deposit associated to the granite is been exploited nowadays by El Aguilar Mining Co since the 1950 ´s (e.g. Brown 1941, 1962; Spencer, 1950, Ahlfeld, 1955; Schalamuk and De Barrio, 2002). Among some of the pioneer papers dealing with the stratigraphy and paleontology of the area, Kobayashi (1936, 1937), Harrington (1938), Harrington and Leanza (1957), Aceñolaza (1966, 1968), Méndez (1973) and Benedetto (1977) introduced the potentiality of the area. Many other papers also focused the locality during the last 20 years, fact that has provided a fairly good amount of biostratigraphic information, that allowed the usage of the Sierra de Cajas as a reference section for the Cambrian-Ordovician boundary in the Central Andean basin (eg.
