D ., 1960 Geology University Microfilms, Inc., Ann Arbor, Michigan OSTRACODA OF THE STOWE CITY BEDS AT STOWE CITY BLUFF, TEXAS A Thesis Submitted to the Graduate Faculty of the Louisiana State University and Agricultural and Mechanical College in partial fulfillment of the requirements for the degree of Doctor of Philosophy in The Department of Geology by Raymond Ll’Artusy M.S., University of Southern California, 1939 June, 1960 Photo blank page ii, per library. ACKNOWLEDGMENTS Although to render adequate thanks is not possible within the scope of this limited acknowledgment, foremost I am grateful for the generous assistance afforded by Dr. H. V. Howe, Director, School of Geology, Louisiana State University, and his sponsorship of the project. Some of the important contributions for which thanks are due Dr. Howe are for suggestion of the thesis problem, for actively supervising the work in progress, for use of his personal library, type collections, topotype material, technical advice, identifications, photographic as­ sistance and especially his time, all of which were more than willingly and freely given. To my wife, Jane Artusy, I am most sincerely grateful for having read and criticized the manuscript, for the interest and care taken in producing the accurate illustrations of the Gstracoda and for the careful drafting of the check list which was facilitated by her technical skill, and for her assistance in a profuse number of other ways all of which enabled the task to progress much more rapidly than otherwise would have been possible. By calling attention to the exceptional Stone City outcrops, by directly assisting the author in the actual taking of field sample data and for liberally making available unpublished Middle Eocene data as well as for critically reading the manuscript, special thanks are Dr. Henryk B. Stenzel of the Shell Development Company, Houston, Texas. iii iv For his valuable assistance, indebtedness and gratitude are extended to Dr. Tetsuro Hanai, University of Tokyo, Tokyo, Japan, who most freely gave of his time by assisting with the general field work, measurement of the section, collection and preparation of samples, checking and comparison of the ostracode genera and the contribution of many valuable suggestions. Dr. Stuart E. Levinson, Research Geologist with the Humble Oil and Refining Corporation, Houston, Texas, is to be thanked for mak­ ing available his large personal library, for making suggestions re­ garding publication and for contributing valuable advice regarding taxonomic procedures and techniques. Mr. Noel P. Brown, Chief Paleontologist, Gulf Oil Corporation, Overseas Division, New York City, New York, read the manuscript criti­ cally and suggested improvements and corrections. This help is grate­ fully acknowledged. The author wishes to express gratitude to Dr. Leslie E. Spock, Professor of Geology, New York University, who read the introduction critically and suggested several improvements and corrections. Mr. Edward Grekulinski, Department of Micropaleontology, Museum of Natural History, New York City, is to be thanked for critically reading the taxonomic descriptions and for giving expert advice on taxonomy. Brother William J. Siemer and Brother Leo J. Bancks of St. Mary's University, San Antonio, Texas, are to be thanked for suggestions and guidance in the use of Latin names applicable to genera and species. V The Middle Eocene type ostracodes at the Smithsonian Insti­ tution, Washington, D.C., many of them Mexican and Texas types of J. A. Cushman and F. M. Swain, were studied and compared with the author's material. This work in Washington was greatly aided by the generous help given by Dr. I. G. Sohn and this assistance is gratefully acknowledged. Acknowledgment is also due Dr. Harold L. Scott of the Univer­ sity of Illinois, Urbana, Illinois, for his loan of the highly valuable colleption of the Sutton and Williams Weches type fossils. As holder of the Stanolind Oil and Gas Company Fellowship at Louisiana State University for the years 1952-54, the writer is properly appreciative and wishes to express sincere thanks for such direct finan­ cial assistance rendered in support of graduate research. To those unnamed individuals who, through careless oversight on my part have failed to receive due acknowledgment for assistance rendered, I must apologize. Raymond L.

This is the second time that the International Symposium on Ostracoda has been held in Germany, following the 5th International Symposium in Hamburg in 1974. The relative importance of Ostracodology - the science that studies Ostracoda - in Germany is further highlighted by well-known names such as G.W. Müller, Klie, Triebel and Helmdach, and others who stand for the long tradition of research on Ostracoda in Germany. During our symposium in Berlin more than 150 participants from 36 countries will meet to discuss all aspects of living and fossil Ostracoda. We hope that the scientific communities working on the biology and palaeontology of Ostracoda will benefit from interesting talks and inspiring discussions - in accordance with the symposium's theme: Ostracodology - linking bio- and geosciences We wish every participant a successful symposium and a pleasant stay in Berlin Berlin, July 27th 2005 Michael Schudack and Steffen Mischke CONTENT Schudack, M. and Mischke, S.: Preface

Kesling Abstract.-The content, arrangement, and rank of suprafamilial taxa of Ostracoda are presently far from settled. Phylogenies based on living ostracods differ seriously from those based on fossil forms. The genus Saipanetta has been suggested to be a surviving relict of the metacopidan superfamily Healdiacea because of its muscle scar pattern and narrow duplicature; never- theless, it differs from the Metacopida in its more complex hingement, lack of a distinct contact groove, exaggerated domiciliar asymmetry, and lack of pos- terior ridges or angulations. The shell morphology and dimorphic structures in the male, such as the clasper on the first thoracic leg and the internal Zenker's organ, strongly support placement of the genus Saipanetta in the Podocopida.

  • Ecology and Classification of Bahamian Cytherellidae (Ostracoda)
    ABSTRACT Four species {three new) of Ostracoda belonging to the family Cytherellidae, collected in the vicinity of Bimini, Bahamas, are described. The influence of water depth, salinity, substrate, and temperature on the distribution of cytherellids is dis- cussed. It is tentatively concluded that cytherellids are restricted to water having salinities above 25 parts per thousand and depths less than 2000 meters.

Manuscript Details Manuscript number MARMIC_2020_33 Title Bounded by crises: an updated view of the evolution of marine ostracods during the Triassic Article type Research Paper Abstract The Triassic has been a turning in the history of biodiversity: bracketed by two major biotic crises, characterized by major biotic, climatic and tectonic events, it has seen the transition from the Palaeozoic to the Modern evolutionary faunas. We propose the first synthetic analysis of the diversity of marine and brackish-water ostracods over the entire Triassic, in the light of palaeoecological, palaeoenvironmental and palaeogeographical contexts. Although general diversity trends witness poor ostracod communities during most of the Early Triassic after the end-Permian crisis, the roots of their Triassic taxonomic rediversification are visible as early as the Dienerian.
