Manger Thesis Director ________________________________ ________________________________ Dr. Christopher Liner Dr. Thomas (Mac) McGilvery Committee Member Committee Member Abstract The geology of Arkansas has been studied for nearly 160 years, and our understanding of it is continually evolving. Part of this ever-changing study is the nomenclature of the stratigraphy. From the early reports to today, several lithostratigraphic names have been proposed and abandoned to improve the accuracy and clarity of the understanding of Arkansas’ geology. Over these 160 years of study, 214 names have been proposed for the Paleozoic beds of Arkansas, with nearly 80 of them currently in use today. These names are a testimony and legacy of the history of Arkansas’ natural resource development and Arkansas’ geologists. Compilations of the Paleozoic stratigraphic nomenclature of Arkansas have been few and far between, with the major publications being from the geologic maps of Arkansas (Miser and Stone, 1929; Haley et al., 1976, revised 1993), two Arkansas Geological Survey publications (Croneis, 1930a; McFarland, 1998, revised 2004), as well as U.S. Geological Survey lexicon publications (Wilmarth, 1938; Keroher et al., 1966; Cohee and Wright, 1976; Lutrell et al., 1981). This study compiles all Paleozoic lithostratigraphic nomenclature, including all abandoned names (indicated by a dagger symbol [†]), as well as both formal and informal names, excluding only the subsurface nomenclature. Some names have been found have conflicting usage between the Arkansas Geological Survey and the U.S. Geological Survey (indicated by an asterisk [*]), requiring further clarification to reduce stratigraphic nomenclatorial problems. © 2017 Noah Morris All Rights Reserved Acknowledgments I would like to take the time to forever thank some good folks who have helped make this work possible. Firstly, my parents, who I’m sure had deep concerns for me when I was little, since I would constantly walk home with pockets full of rocks. They have always encouraged me to pursue my interests and supported me in everything that I’ve done. Thank you. Secondly, my advisor, Dr. Manger. This work was his idea, but he let me steal it and run with it. I didn’t mean for it to become my thesis, but here we are. I am appreciative for all the helpful insight and suggestions from him that have vastly improved this work. Thanks to my committee members, Dr. Liner and Dr. McGilvery, for being willing to hear me yammer on about this thesis. Also, a word of appreciation goes out to those I’ve met along the way. Some of whom have contributed to putting the idea of me going back to school in my head. I hope you know that this is partly your fault. You know who you are. Lastly, special thanks goes out to you, dear reader. You have read at least one page of my thesis. Thank you. Dedication This thesis is dedicated to rocks. Without them, this work would not have been possible. Table of Contents I.

  • Palaeontologia Electronica DISCRIMINATION OF
    Palaeontologia Electronica http://palaeo-electronica.org DISCRIMINATION OF FENESTRATE BRYOZOAN GENERA IN MORPHOSPACE Steven J. Hageman and Frank K. McKinney ABSTRACT Concepts for generic diagnoses and discrimination of biserial fenestrate Bryozoa (Fenestellidae) have varied historically, but have largely been based on specialized colony forms (e.g., Archimedes), the shape and budding arrangement of chambers and other internal skeletal features such as hemisepta, and occasionally on the pres- ence or absence of discrete characters, such as placement of nodes on the frontal sur- face (e.g., Minilya). The question remains as to whether biserial fenestrate genera represent real biological clades, or whether they are convenient groupings of morpho- types based on untested characters. This study evaluates the distribution of 1075 operational taxonomic units (OTUs) from 15 fenestrate genera with measurements for nine morphometric characters – external features are not emphasized in most generic diagnoses. Here, each OTU represents a composite or idealized individual from a col- ony. Results show that OTUs plotted in principal component space do largely form coherent clusters based on a priori generic assignments. Thus the groupings based on characters other than the ones used to originally define them, add support to the notion of biological significance for recognized genera. The exceptions actually highlight and help resolve known issues. Therefore, we recognize Alternifenestella as a junior syn- onym of the genus Spinofenestella, and propose reassignment of Laxifenestella serrat- ula in Snyder (1991) to Fenestella serratula, and Fenestella sp. 1 in Ernst and Schroeder (2007) as Rectifenestella. We do not advocate that biserial fenestrate generic concepts should be based on the nine external characters used in this study, but rather that they can be used independently to evaluate the coherence of genera based on other discrete characters.

It is a known producer of hydrocarbons in the subsurface of Oklahoma and Kansas. There is a high level of complexity associated with the Bentonville and other Mississippian formations resulting in inadequate correlations and poor well performance in some cases. This stems from the use of oversimplified depositional models and limited understanding of how the Mississippian System responded and evolved over time as a result of sea level variation at various frequencies.
