Ettensohn, Professor of Geology Lexington, Kentucky 2018 Copyright Ann Well Harris 2018 ABSTRACT OF DISSERTATION OCCURRENCE AND ATTRIBUTES OF TWO ECHINODERM-BEARING FAUNAS FROM THE UPPER MISSISSIPPIAN (CHESTERIAN; LOWER SERPUKHOVIAN) RAMEY CREEK MEMBER, SLADE FORMATION, EASTERN KENTUCKY, U.S.A. Well-preserved echinoderm faunas are rare in the fossil record, and when uncovered, understanding their occurrence can be useful in interpreting other faunas. In this study, two such faunas of the same age from separate localities in the shallow-marine Ramey Creek Member of the Slade Formation in the Upper Mississippian (Chesterian) rocks of eastern Kentucky are examined. Of the more than 5,000 fossil specimens from both localities, only 9–34 percent were echinoderms from 3–5 classes. Nine non-echinoderm (8 invertebrate and one vertebrate) classes occurred at both localities, but of these, bryozoans, brachiopods and sponges dominated. To understand the attributes of both localities (Valley Stone and 213 quarries), the geologic and structural settings, lithofacies and depositional environments, as well as faunal makeup and abundances (diversity, evenness, density), were compared and contrasted. Faunas from the Valley Stone Quarry were located on an uplifted fault block in more shallow, open-marine waters with higher energies. As indicated by four distinct lithofacies, the depositional setting was more extensive and varied with interspersed shoals and basins that could accommodate a greater richness (65 species), even though organism densities and abundance were less. In contrast, fauna from the 213 Quarry were located on a downdropped fault block in a more localized, deeper, storm-shelf setting, characterized by a single lithofacies. Although organism density and abundance were nearly twice as high as that at the Valley Stone Quarry, species richness was lower (45 species), and only one species, a bryozoan, predominated. Overall, echinoderm classes, species and individuals were more abundant at the Valley Stone Quarry, and I suggest that this is related to the shallower and more varied depositional environments that developed in response to presence on the shallow, uplifted fault block. This suggests the importance of regional features like faults in controlling environments and organism distribution through time. Although the faunas were originally collected for their echinoderm-dominated “crinoid gardens,” in fact, echinoderms were in the minority, and bryozoans and brachiopods predominated in the communities. Hence, the communities might better be described as bryozoan “thickets” and brachiopod “pavements.” KEYWORDS: Late Mississippian, Slade Formation, echinoderms, diversity, richness, depositional environments.

Woolery Director of Graduate Studies June 28, 2018 ACKNOWLEDGMENTS It is a pleasure to thank many people who made this dissertation possible. Foremost, I want to thank my advisor Dr. Frank R. Ettensohn. It has been an honor to be his Ph.D. student. With his enthusiasm, inspiration, and his efforts to explain things clearly, he helped to make geology enjoyable for me. Throughout my dissertation, he provided encouragement, sound advice, good teaching, and any good ideas. I appreciate all his contributions of time, ideas, to make my Ph.D. experience productive and invaluable. I am also thankful for the excellent example he has provided as a successful geologist and professor. My deepest gratitude is due to the members of the supervisory committee, Dr. Rebecca Freeman, Dr. Alan E. Fryar, Dr. Stephen F. Greb, and Dr. Carol Baskin, without whose knowledge and assistance, this study would not have been successful. My committee members have been an excellent source of advice, feedback, and collaboration. In addition, they have contributed immensely to my personal and professional time at the University of Kentucky. I want to thank my outside examiner, Dr. Timothy Taylor. I want to express my sincere gratitude to Professor Jill Carnahan-Jarvis, Eastern Kentucky University, for her guidance with the statistics, math, graphs, and charts that made this dissertation possible. Her help has been invaluable and has ranged from being my mentor and best friend at a time when I needed someone the most. I would have been lost without her mentorship, encouragement, and friendship. I am thankful for my late master’s thesis advisor, Dr. Robert T. Lierman, Eastern Kentucky University. His encouragement and support throughout the years have been instrumental in my success as a graduate student and adjunct instructor. I will always carry your memory and teaching methods with me. I would like to express my gratitude to Mr. Stephen Moore, Studiospectre, for providing assistance as a paleoartist for the figures and drawings in this dissertation. His efforts are greatly appreciated and made this dissertation possible. I would like to thank Ms. Adrianne Gilley, Department Manager, for her invaluable help and support during my graduate student career at the Department of Earth and Environmental Sciences, University of Kentucky. Lastly, I wish to express my love and gratitude to my family for their understanding and support. Being a first-generation college student, their support has been instrumental in my success. I am grateful for wonderful parents that always believed in me. To my late father, Mr. Billy Wayne Harris, I dedicate this dissertation. Although it has been a few months since you have passed, I carry your life lessons (and my middle name) with me, every day.

Although only one specimen of each is known, it is well preserved. The new Agnrico- crinus bears a resemblance to A. ponderoszts Wood, and the new Actinocriniles to four species described by Miller & Gurley: A. spergenensis, A. botuztosz~s,A. gibsoni, and A. shnronensis. A preliminary survey of species assigned to Agaricocrinz~ssuggests that revision of the genus is overdue. Although the occurrence of the specimens leaves some doubt as to their stratigraphic posi- tion, we conclude that they both probably weathered from the Fort Payne formation and rolled down the slope onto the New Providence, where they were found. The sites where the crinoids were picked up are now deeply inundated by water impounded by the Wolf Creek dam on the Cumberland River.

    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.

  • An Enigmatic Chondrichthyan with Paleozoic Affinities from the Lower Triassic of Western Canada
    An enigmatic chondrichthyan with Paleozoic affinities from the Lower Triassic of western Canada RAOUL J. MUTTER and ANDREW G. NEUMAN Mutter, R.J. and Neuman, A.G. 2006. An enigmatic chondrichthyan with Paleozoic affinities from the Lower Triassic of western Canada. Acta Palaeontologica Polonica 51 (2): 271–282. Listracanthus pectenatus sp. nov. represents the youngest record of the enigmatic chondrichthyan Listracanthus. This new species is the only Mesozoic record of this genus and highlights survival of a rare and enigmatic group of cartilagi− nous fishes across the Paleozoic–Mesozoic boundary. In the Vega−Phroso Siltstone Member of the Sulphur Mountain Formation (western Canada), two kinds of numerous dermal denticles identified as Listracanthus occur predominantly in strata probably of early Smithian age. The new species differs from all other known species of the genus in the structure of the anterior and posterior borders of the large denticles. The small denticles appear to be less diagnostic than the large ones and are readily distinguished from small denticles generally assigned to the genus Petrodus. Histology reveals that the largest denticles were originally hollow, probably secondarily ossified as acellular bone. The conclusion drawn by previous authors that Listracanthus may be a petalodontid shark, based on ambiguous non−skeletal associations with Deltoptychius, Petrodus, or Calopodus is not supported by this study. The large number of denticles, the size of both types of denticles and their arrangement suggest that Listracanthus pectenatus sp. nov. was a large chondrichthyan of aberrant body shape and yet uncertain systematic position. Key words: Chondrichthyes, denticles, Listracanthus, Smithian, histology, British Columbia. Raoul J.
