" $ /0& $ Anatomy of Middle Devonian Faunal Turnover in Eastern North America: Implications for Global Bioevents at the Eifelian-Givetian Stage Boundary A dissertation submitted to the Graduate School University of Cincinnati in partial fulfilment of the requirements for the degree of Doctor of Philosophy Department of Geology McMicken College of Arts and Sciences November 2010 By Michael K. DeSantis B.A., Boston University, 1992 M.S., University of Idaho, 1996 Committee Chair: Carlton E. Brett, Ph.D. ABSTRACT The late Eifelian-earliest Givetian interval (Middle Devonian) represents a time of significant faunal turnover both in the eastern North America and globally, herein termed the Late Eifelian Biocrisis. A synthesis of biostratigraphic, K-bentonite, and sequence stratigraphic data, indicates that physical and biotic events in the Appalachian foreland basin sections in New York are coeval with the predominantly carbonate platform sections of the adjacent midcontinent. The succession includes portions of three distinctive benthic faunas or ecological-evolutionary sub- units (EESUs): ‘Onondaga’, ‘lower Marcellus’, and ‘Hamilton’. In the northern Appalachian Basin in New York the boundaries of these bioevents show evidence of abrupt, widespread extinctions/extirpations, immigration and ecological restructuring. Regional analysis of faunas shows that EESUs comparable to the northern Appalachian Basin succession are recognizable within the coeval carbonate ramp and platform strata of central Ohio and southeastern Indiana, as well as in the Michigan Basin. However, faunas of the Wabash Platform area of central Ohio and southeastern Indiana show slightly higher persistence compared to those of the Appalachian Basin, indicating that the Wabash Platform served as a refuge for species extirpated from the Appalachian Basin by environmental changes brought on by tectonic and eustatic deepening. This interval can be subdivided into three discrete bioevents, with the last being the widely recognized Kaák Event in the ensensis conodont Zone near the Eifelian-Givetian stage boundary. The earlier bioevents, within the australis to eiflius Zones, are defined by striking faunal changes in the Appalachian Basin and coeval formations in adjacent areas of eastern North America. The Bakoven Event (australis conodont Zone), is marked by a significant reduction in faunal diversity in the uppermost Onondaga Limestone and overlying Bakoven Black Shale that is associated with eustatic/tectonic deepening and widespread hypoxia. The iii Stony Hollow Event (kockelianus-eiflius Zone) is marked by an incursion of tropical Old World Realm Cordilleran Province taxa, including distinctive atrypid brachiopods, corals, and bivalves, into the subtropical to temperate shelf region of eastern North America. The Stony Hollow bioevent appears to be associated with altered current patterns and/or climatic regime during the kockelianus-eiflius Zone interval. Approximately coeval formations in Europe and Morocco show the probable signatures of these events, indicating that the Bakoven and/or Stony Hollow may be global-scale events. In particular, the late Eifelian successions in the Eifel and Rhenish Schiefergebirge areas of Germany, and in the Cantabrian Mountains of Spain show evidence for faunal turnover during the interval of the australis-kockelianus Zones. Both the Bakoven and Stony Hollow and the terminal Kaák events appear to be associated with changes in climatic gradients and major disturbances in the global carbon cycle. iv v ACKNOWLEDGMENTS Many, many people helped in various ways, shapes and forms with this project. I would particularly like to thank my advisor Dr. Carl Brett; who is the reason I moved to the mid-west in the first place, and who has been a mentor and friend throughout this long process. I would also like to express my appreciation to the other members of my committee: Dr. Warren Huff, Dr. Tom Algeo, Dr. Dave Meyer, and Dr. Arnold Miller, and my outside committee member Dr. Charles Ver Straeten at the New York State Museum for their support. Thanks also to fellow UC Geology graduate students, especially Alex Bartholomew, Pat McLaughlin, and Sean Cornell for help with field and lab work, discussion of aspects of this study and geology in general. Thanks also to Rick Bullard for showing me some of the local color (in addition to geology) of SE Ohio/N. Kentucky; particularly the fun times out on the sporting clays course, as well as shooting trap and sighting in rifles down at “Ed’s field”. Keep your powder dry, amigo! For contributions to fieldwork, laboratory analyses, and various other aspects of this project I’d like to thank, in no particular order: Dr. P. Bultynck for revisiting and confirming identifications of conodonts from the base of the Rogers City Formation. Dr. R.T. Becker for providing additional litho- and biostratigraphic details of the Hassi Mouf section in Morocco. Dr. D. J. Over for processing and identifying conodonts from samples collected from several central Ohio localities. Dr. George Shaw, who answered my numerous questions regarding his method for analyzing apatites and generously provided me with some of his apatite calibration standard. The staff at the Microscopic Analysis Research Center at Ohio State University (John Olesik, Anthony Lutton, Lisa Fay) for helping to adapt Dr. Shaw’s analysis method, and teaching me how to 'drive' the ICP-MS. The staff of the Ohio Geological Survey’s Horace R. Collins vi Laboratory (Ron Rhea and Greg Schumacher) and of the Ontario Oil, Gas and Salt Resources Library for access to drill cores. The many quarry operators and property owners who allowed access onto their land – in particular John Chester, Jr. and family, of Columbus, OH who always greeted us cheerfully, even when we showed up unexpectedly with a large group of students. Last, but by no means least, I thank my parents, Mark and Gail DeSantis for your unflagging support of all my endeavours throughout the years. You gave me the freedom to steer my own course through life, while providing just the right amount of advice and guidance. vii TABLE OF CONTENTS INTRODUCTION .......................................................................................................................... 1 CHAPTER 1: Persistent Depositional Sequences and Bioevents in the Eifelian (early Middle Devonian) of eastern Laurentia: North American evidence of the Kaák Events? ........................ 5 Abstract.........................................................................................................................................5 1.1 Introduction.............................................................................................................................6 1.2.

  • Late Carboniferous Bryozoans from La Hermida, Spain
    Late Carboniferous bryozoans from La Hermida, Spain Andrej Ernst and Elke Minwegen Acta Palaeontologica Polonica 51 (3), 2006: 569-588 Fifteen bryozoan species belonging to thirteen genera have been identified from an outcrop of the Picos de Europa Formation (Moscovian, Upper Carboniferous) at La Hermida in northern Spain. Three species and one genus are new Coscinium hermidensis sp. nov., Cystodictya pustulosa sp. nov., and Cystocladia hispanica gen. et sp. nov. Rhabdomesid bryozoans are the most diverse order with seven species, followed by cystoporids (four species), fenestellids (three species) and trepostomids (one species). Bryozoans with erect branched or reticulate colonies dominate in the studied assemblage; only two species possess encrusting colonies. Together with associated crinoids, the bryozoan assemblage indicates a subtidal environment below the zone of vigorous water movement. The La Hermida bryozoan fauna confirms the Upper Carboniferous age of the Picos de Europa Formation and allows various biogeographical interpretations. All previously known species of the genus Coscinium were reported from the Lower Permian of Russia. Clausotrypa monticola is known from the Lower Permian of Russia and Arctic as well as from the Upper Carboniferous of Carnic Alps (Austria). Rhabdomeson cf. propatulissimum and Penniretepora pseudotrilineata are known from the same level of Italian Carnic Alps. Streblotrypa (Streblascopora ) nikiforovae and Rhombocladia punctata are known from the Upper Carboniferous (Moscovian) of Ukraine. Fistulipora petaloida is known from Kasimovian Stage of Russian Plate. Several other species show connections with North America. Key words: Bryozoa, Cystoporida, Fenestellida, Carboniferous, Picos de Europa Formation, Spain.

  • Message from the New Chairman
    Subcommission on Devonian Stratigraphy Newsletter No. 21 April, 2005 MESSAGE FROM THE NEW CHAIRMAN Dear SDS Members: This new Newsletter gives me the pleasant opportunity to thank you for your confidence which should allow me to lead our Devonian Subcommission successfully through the next four years until the next International Geological Congress in Norway. Ahmed El Hassani, as Vice-Chairman, and John Marshall, as our new Secretary, will assist and help me. As it has been our habit in the past, our outgoing chairman, Pierre Bultynck, has continued his duties until the end of the calendar year, and in the name of all the Subcommission, I like to express our warmest thanks to him for all his efforts, his enthusi- asm for our tasks, his patience with the often too slow progress of research, and for the humorous, well organized and skil- ful handling of our affairs, including our annual meetings. At the same time I like to thank all our outgoing Titular Members for their partly long-time service and I express my hope that they will continue their SDS work with the same interest and energy as Corresponding Members. The new ICS rules require a rather constant change of voting members and the change from TM to CM status should not necessarily be taken as an excuse to adopt the lifestyle of a “Devonian pensioner”. I see no reason why constantly active SDS members shouldn´t become TM again, at a later stage. On the other side, the rather strong exchange of voting members should bring in some fresh ideas and some shift towards modern stratigraphical tech- niques.

  • 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.

Etyrnologically the word "geology" should apply equally to the study of both these regions, but, for convenience and from the limitation of the individual human mind, it is usually confined to the problems presented by the rocks composing the crust, wMle those of the deeper regions lie outside its scope. Such, briefly, are the conclusions which may be drawn from the sciences of terrestrial observation. The statement, I know, is in- complete and imperfect; some at least of the conclusions will doubtless be traversed and regarded as incompatible with the results obtained from other lines of research, but in their main features of the threefold division of physical condition and the twofold division ot'chemical composition they seem to me so well founded that the burden of proof lies with those who would traverse, rather than with those who are prepared to accept, them. V.—NOTES ON AMMONITES. By L. F. SPATH, B.SC, F.G.S. I. TI1HE following notes were compiled, for the most part, some years J_ ago, but their publication in the present form suggested itself to the writer on the perusal (during a short "leave" from active service) of a number of recent papers ou Ammonites, principally Professor Swinnerton and A. E. Trueman's study of the " Morphology and Development of the Ammonite Septum".1 The main part of that inquiry is devoted to the development of the septum, illustrated by successive " septa 1 sections", and it is claimed that where sutural development cannot be worked out, "septal sections" will to some extent serve as a substitute.
