A Redescription and Phylogenetic Analysis of the Cretaceous Fossil Lizard Polyglyphanodon Sternbergi Gilmore, 1940
A Redescription and Phylogenetic Analysis of the Cretaceous Fossil Lizard Polyglyphanodon sternbergi Gilmore, 1940 by Meredith Austin Fontana B.S. in Biology, May 2011, The University of Texas at Austin A Thesis submitted to The Faculty of The Columbian College of Arts and Sciences of The George Washington University in partial fulfillment of the requirements for the degree of Master of Science August 31, 2014 Thesis directed by James M. Clark Ronald Weintraub Professor of Biology © Copyright 2014 by Meredith Austin Fontana All rights reserved ii This thesis is dedicated to the memory of my grandmother, Lee Landsman Zelikow – my single greatest inspiration, whose brilliant mind and unconditional love has profoundly shaped and continues to shape the person I am today. iii ACKNOWLEDGEMENTS I am deeply grateful to my graduate advisor Dr. James Clark for his support and guidance throughout the completion of this thesis. This work would not have been possible without his invaluable assistance and commitment to my success, and it has been a privilege to be his student. I would also like to express my appreciation to the additional members of my Master’s examination committee, Dr. Alexander Pyron and Dr. Hans-Dieter Sues, for generously contributing their knowledge and time toward this project and for providing useful comments on the manuscript of this thesis. I am especially grateful to Dr. Sues for allowing me access to the exquisite collection of Polyglyphanodon sternbergi specimens at the National Museum of Natural History. I am also extremely thankful to the many faculty members, colleagues and friends at the George Washington University who have shared their wisdom and given me persistent encouragement. -

Lyons Florida Department of Natural Resources Marine Research Laboratory St. Petersburg, Florida 33701 ABSTRACT Eulima subcarinata Orbigny, 184.2, is redescribed and transferred to the genus Eulimostraca Bartsch, 1917. The species occurs from the Caribbean and Yucatan to intermediate-depth shelf waters off Florida and North Carolina. Confusion regard ing the species’ identity is discussed. Eulima carolii Dali, 1889 (formerly affinis C. B. Adams, 1850, non Philippi, 1844) is considered nomen a dubium. Orbigny (1842) introduced the name Eulima of typical, unornamented melanellid form but subcarinata for a small melanellid from with a peripheral line suggesting a low carina on Guadeloupe, West Indies. Among the characters the last whorl. included in his Latin description (1845) were “an- Mörch (1875) reported the species from St. fractibus octonis. linea fulva omatis, ultimo Thomas [Virgin Islands]; and Dali (1889a) ex subcarinato”, expanded in French (1853) as “le tended the range to the southeastern United dernier [tour] un peu caréné en avant.

He stated that the East Side, from 37 to 110 St., probably afforded the most specimens. The various tunnels and their minerals were spoken of. Capt.

Late Devonian (Frasnian) bivalves from the Nocedo Formation – the results of Wilhelm Kegel’s 1927 field trip to northern Spain Michael R.W. Amler Amler, M.R.W. Late Devonian (Frasnian) bivalves from the Nocedo Formation – the results of Wil- helm Kegel’s 1927 field trip to northern Spain. Scripta Geologica Special Issue, 7: 13-34, 9 figs., Leiden, December 2010. Michael R.W. Amler, Department für Geo- und Umweltwissenschaften, Sektion Geologie, and Geo- Biocenter Munich, Ludwig-Maximilians-Universität München, Luisenstr. 37, D-80333 München, Ger- many ([email protected]), and Institut für Geologie und Paläontologie im Fachbereich Geographie der Philipps-Universität Marburg, Hans-Meerwein-Str., D-35032 Marburg, Germany ([email protected]). Key words — Bivalvia, Rhenish Facies, Nocedo Formation, Frasnian, Cantabrian Mountains, Iberia, Wilhelm Kegel. During a field trip to the Peña-Corada Unit of the southernmost Esla region of the Cantabrian Moun- tains in 1927, the German stratigrapher Wilhelm Kegel sampled brachiopods and bivalves from a section in the Laoz valley near La Ercina. The stratigraphic position is believed to be part of the No- cedo Formation of Frasnian age. This fauna includes poorly preserved steinkerns of a near-shore bi- valve fauna that was prepared for publication including labels and proposed names, but never pub- lished. The fauna represents only a very small and random part of the former community. But as in- formation on Frasnian bivalves is scarce, the few specimens add important information on the distri- bution and palaeogeographic occurrence of near-shore, that is, Rhenish Facies bivalves within the south Laurussian – Rheic Ocean Realm. -
