Alfred Romer – Wikipedia
Alfred Romer – Wikipedia https://de.wikipedia.org/wiki/Alfred_Romer aus Wikipedia, der freien Enzyklopädie Alfred Sherwood Romer (* 28. Dezember 1894 in White Plains, New York; † 5. November 1973) war ein US-amerikanischer Paläontologe. Sein Fachgebiet war die Evolution der Wirbeltiere. Inhaltsverzeichnis 1 Leben 2 Romer-Lücke 3 Auszeichnungen und Ehrungen 4 Schriften 5 Weblinks 6 Einzelnachweise Leben Alfred Sherwood Romer wurde in White Plains, New York geboren, wo er seinen High-School-Abschluss machte. Danach arbeitete er ein Jahr lang als Angestellter bei der Eisenbahn und entschloss sich dann doch für den Besuch eines College. Mit Hilfe eines Stipendiums vom Amherst College konnte er dort Geschichte und deutsche Literatur studieren. Durch häufige Besuche des American Museum of Natural History entdeckte er seine Begeisterung für naturkundliche Fossilien. Bei Ausbruch des Ersten Weltkriegs meldete er sich als Freiwilliger zum Kriegsdienst und wurde sofort in Frankreich eingesetzt. 1919 kam er zurück nach New York und nahm das Studium der Biologie an der Columbia University auf, das er bereits zwei Jahre später mit der Promotion abschloss. Danach war er als wissenschaftliche Hilfskraft an der Bellevue Medical School der New York University beschäftigt und lehrte insbesondere Histologie, Embryologie und Allgemeine Anatomie. 1923 erhielt er einen Ruf von der Universität Chicago, wo er seine spätere Ehefrau Ruth kennenlernte, mit der er drei Kinder hatte. In Chicago fand er Bedingungen vor, die es ihm ermöglichten, sein Hauptinteresse zu intensivieren - die Paläontologie. So entstanden in den Jahren von 1925 bis 1935 37 Fachartikel, die sich mit diesem Thema befassten. 1934 wurde er zum Professor für Biologie an der Harvard University ernannt. -

New Information on the Evolution of the Bradyodont Chondrichthyes the Lf
UBUVERSt' 3? KJUN01S i H UWNA-CHAMPAICN L30LOGY «H CD FIELDIANA Geology Published by Field Museum of Natural History Volume 33, No. 28 July 29, 1977 This volume is dedicated to Dr. Rainer Zangerl New Information on the Evolution of the Bradyodont Chondrichthyes The Lf Richard Lund 1H7C Department of Biology IYIhK 1 4 1^1 C Adelphi University University oj Illinois INTRODUCTION * UrbanaCham ^» Among the taxa of Chondrichthyans from the upper Mississip- pian Bear Gulch Limestone of Montana (Lund, 1974; Lund and Zangerl, 1974) are holomorphs of four petalodonts, two cochlio- donts, and a chimaeroid. These forms have all been included by vari- ous authors within the Holocephali, or Bradyodonti, usually ranked as a subclass within the Chondrichthyes (Arambourg and Bertin, 1958; Obruchev, 1967). Holomorphs of bradyodont fish are ex- tremely rare (Patterson, 1965) and considerable controversy sur- rounds the inter-relationships of the Bradyodonti and the phyletic position of the group (Patterson, 1968; Bendix-Almgreen, 1968; 1970). This paper attempts to relate some new information to the evolution of the Bradyodont chondrichthyes. CLASS CHONDRICHTHYES: The Chondrichthyes are char- acterized by a cartilaginous endoskeleton which may be superfi- cially calcified; an exoskeleton composed of cyclomorial, synchro- nomorial, or lepidomorial scales which may be lost, modified as cephalic spines, or fused into plates; gill chambers covered by an opercular fold or opening separately to the outside; the absence of an air bladder or lung; otoconia, not compact otoliths in the inner ear which remains open to the outside through endolymphatic ducts. Internal fertilization with copulation is present, males have claspers developed as extensions of the axis of pelvic fins. -
A New Lower Devonian Arthrodire (Placodermi) from the NW Siberian Platform
Estonian Journal of Earth Sciences, 2013, 62, 3, 131–138 doi: 10.3176/earth.2013.11 A new Lower Devonian arthrodire (Placodermi) from the NW Siberian Platform Elga Mark-Kurik Institute of Geology at Tallinn University of Technology, Ehitajate tee 5, 19086 Tallinn, Estonia; [email protected] Received 24 August 2012, accepted 5 November 2012 Abstract. A new genus and species of arthrodires, Eukaia elongata (Actinolepidoidei, Placodermi), is described from the Lower Devonian, ?Pragian of the Turukhansk region, NW Siberian Platform. A single specimen of the fish, a skull roof, comes probably from the lower part of the Razvedochnyj Formation. The occurrence of an actinolepidoid arthrodire in the Early Devonian of this area of Siberia is unexpected. Eukaia shows some distant relationship with the genus Actinolepis, but several features indicate similarity to representatives of other arthrodires. Key words: actinolepidoid arthrodire, placoderm, Lower Devonian, ?Pragian, NW Siberian Platform. INTRODUCTION (Fig. 1).

Development, Anatomy, and Phylogenetic Relationships of Jawless Vertebrates and Tests of Hypotheses About Early Vertebrate Evolution
Development, Anatomy, and Phylogenetic Relationships of Jawless Vertebrates and Tests of Hypotheses about Early Vertebrate Evolution by Tetsuto Miyashita A thesis submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy in Systematics and Evolution Department of Biological Sciences University of Alberta © Tetsuto Miyashita, 2018 ii ABSTRACT The origin and early evolution of vertebrates remain one of the central questions of comparative biology. This clade, which features a breathtaking diversity of complex forms, has generated profound, unresolved questions, including: How are major lineages of vertebrates related to one another? What suite of characters existed in the last common ancestor of all living vertebrates? Does information from seemingly ‘primitive’ groups — jawless vertebrates, cartilaginous fishes, or even invertebrate outgroups — inform us about evolutionary transitions to novel morphologies like the neural crest or jaw? Alfred Romer once likened a search for the elusive vertebrate archetype to a study of the Apocalypse: “That way leads to madness.” I attempt to address these questions using extinct and extant cyclostomes (hagfish, lampreys, and their kin). As the sole living lineage of jawless vertebrates, cyclostomes diverged during the earliest phases of vertebrate evolution. However, precise relationships and evolutionary scenarios remain highly controversial, due to their poor fossil record and specialized morphology. Through a comparative analysis of embryos, I identified significant developmental similarities and differences between hagfish and lampreys, and delineated specific problems to be explored. I attacked the first problem — whether cyclostomes form a clade or represent a grade — in a description and phylogenetic analyses of a new, nearly complete fossil hagfish from the Cenomanian of Lebanon. -

An Idiosyncratic History of Floridian Vertebrate Paleontology
Bull. Fla. Mus. Nat. Hist. (2005) 45(4): 143-170 143 AN IDIOSYNCRATIC HISTORY OF FLORIDIAN VERTEBRATE PALEONTOLOGY Clayton E. Ray1 The history of vertebrate paleontology of Florida is reviewed, analyzed, and compared and contrasted to that of North America as a whole. Simpson’s (1942) organization of the history of the subject for North America into six periods is modified and extended to fit the special case of Florida. The beginning of vertebrate paleontology in Florida is shown to have trailed that of the continent in general by at least a century and a half, and its advancement to have lagged at every period by several decades for most of its history, but to have accelerated dramatically in recent decades, resulting in integration and equality, if not superiority, for Florida at present and for the future.
