PURNELL Part I: Paleozoic Cephalopoda SMITHSONIAN INSTITUTION PRESS WASHINGTON, D.C. 1968 Publications of the United States National Museum The scientific publications of the United States National Museum in- clude two series, Proceedings of the United States National Museum and United States National Museum Bulletin. In these series are published original articles and monographs dealing with the collections and work of the Museum and setting forth newly ac- quired facts in the field of anthropology, biology, geology, history, and technology. Copies of each publication are distributed to libraries and scientific organizations and to specialists and others interested in the various subjects. The Proceedings, begun in 1878, are intended for the publication, in separate form, of shorter papers. These are gathered in volumes, octavo in size, with the publication date of each paper recorded in the table of contents of the volume. In the Bulletin series, the first of which was issued in 1875, appear longer, separate publications consisting of monographs (occasionally in several parts) and volumes in which are collected works on related sub- jects. Bulletins are either octavo or quarto in size, depending on the the needs of the presentation. Since 1902, papers relating to the botanical collections of the Museum have been published in the Bulletin series under the heading Contributions from the United States National Herbarium. This work forms number 262 of the Bulletin series. FRANK A. TAYLOR Director, United States National Museum U.S. GOVERNMENT PRINTING OFFICE WASHINGTON : 1968 Introduction By Richard S. Boardman The Paleozoic cephalopod catalog is the first in a proposed series listing invertebrate fossil type specimens of the Division of Invertebrate Paleontology of the Smithsonian Institution. The only other published catalog (Schuchert, 1905, USNM Bulletin 53, pt. 1) covered the entire type collection of fossil invertebrates held at that time. Since 1905 the type collections have grown from approximately 11,500 to nearly 200,000 (fig. 1). In compiling the cephalopod catalog all illustrated types were com- pared with published pictures, and all of the nomenclature was rechecked. This is necessarily a long and detailed task accomplished with meticu- lous attention by Museum Specialist Louis R. Purnell, under the super- vision of Erie G. Kauffman, Frederick J. Collier, and myself. All of the Paleozoic cephalopod type specimens acquired through 1965 are listed. The Collection Specimens in the type collections include the primary types and sec- ondary types designated in the literature. Designation can be by illus- stration, or isolation in the text by measurement of other mention. Each individually mentioned type specimen receives a separate catalog num- ber. Primary or secondary types which have not received individual designation are collected into occurrence suites and each suite is given a catalog number. Kinds of primary types differentiated in the collection include holotypes, syntypes, lectotypes, paratypes, paralectotypes, and neotypes, as defined in articles 73-75 of the International Code of Zoo- logical Nomenclature. Secondary types identified to species are gener- ally termed hypotypes for curatorial purposes. Secondary types not identified to species or identified with a degree of doubt are termed simply figured or mentioned specimens. Plastotypes are cataloged and placed in the type collections when illustrations, descriptions, or meas- urement are based on the plastotype itself. Other plastotypes are in- cluded in the type collection at the discretion of the curator. In addition to the type collection listed in this catalog, the division Curator-in-Charge, Division of Invertebrate Paleontology. U.S. NATIONAL MUSEUM BULLETIN 262 maintains a large nontype collection of identified specimens arranged taxonomically, in cooperation with the Paleontology and Stratigraphy Branch of the U.S. Geological Survey. Unstudied specimens are gener- ally filed by occurrence data in a third collection. The Catalog The cephalopod catalog is divided into four major chapters: Nautiloidea, Ammonoidea, Bactritoidea, and Coleoidea. Within each chapter the taxa are listed alphabetically by genus and species. With one exception, a specimen is entered only once and under the first generic and species combination assigned, regardless of the number of times it is redescribed or reillustrated. The exception is a previously described specimen that is redescribed as a primary type of a new species, whether or not the generic designation is also changed. The catalog is meant to be an objective and brief listing of type speci- mens and not a source book for occurrence data, synonymies, or strati- graphic interpretation of any kind. Individual citations include the bino- men, author, date, page, plate, figure numbers, kind of type, catalog number, rock unit as originally designated, and state, province, or coun- try, whichever best applies. A full bibliography is located at the end of the catalog. Use of the Collections VISITORS TO THE MUSEUM.-Qualified professional people and grad- uate students recommended by their universities are welcomed and en- couraged to use the collections of the division. Equipment is limited, especially during university vacation periods, so it is generally useful to inquire in advance about availability. Research areas are generally closed on Sundays and holidays. LOANS.—Loans of specimens in all categories are made regularly by mail in North America, and all but holotypes are loaned abroad. During fiscal 1966, 12,869 specimens were sent out on loan. Loans are made to educational and research institutions for the use of their professional staff within institutional quarters only. Loans for the use of graduate students are made through their major professor or departmental head. Nontype material is loaned for 2 months, or longer if needed. Loans will not be made to private individuals at private homes. TYPE SPECIMENS OF INVERTEBRATE FOSSILS NUMBER OF TYPE SPECIMENS ro ^ 0s od O o O O O o o O O o o O 4 U.S. NATIONAL MUSEUM BULLETIN 262 Type specimens are loaned for 2-week periods and sent by registered mail. People with requests for large loans of types are urged to come to the museum to study them. If a visit is not feasible, types are mailed in smaller lots; each lot is sent out upon return of the last one. Although the division has not had a loss using registered mail in recent years, it is better to risk just a few types in any one mailing. Silicified or other fragile specimens are not loaned because of the probability of breakage. Types from the Springer Echinoderm collection cannot be loaned out be- cause of the terms of the bequest. DEPOSIT OF TYPE SPECIMENS.-It is Smithsonian policy to accept all types sent in for permanent deposit by authors working outside the Institution. This is done regularly by taxonomists who do not have a stable repository convenient to them. It is recommended that those authors who plan to deposit types at the Smithsonian Institution write to the Division of Invertebrate Paleontology, U.S. National Museum, Washing- ton, D.C. 20560, to ask for a block of catalog numbers, one for each in- dividually designated specimen and paratype of hypotype suite. These numbers will be reserved and will be sent immediately to the author so that they can be included in the manuscript and published. Numbered specimens should be deposited by the time of publication. It is the re- sponsibility of the author to prepare specimens for permanent storage and to identify specimens with their assigned catalog numbers. Specimens sent in before publication will not be available for examination by any- one without the author's permission until published. At that time, the technical staff of the museum will catalog, label, and place the speci- mens in the collections.

  • Message from the New Chairman
    Subcommission on Devonian Stratigraphy Newsletter No. 21 April, 2005 MESSAGE FROM THE NEW CHAIRMAN Dear SDS Members: This new Newsletter gives me the pleasant opportunity to thank you for your confidence which should allow me to lead our Devonian Subcommission successfully through the next four years until the next International Geological Congress in Norway. Ahmed El Hassani, as Vice-Chairman, and John Marshall, as our new Secretary, will assist and help me. As it has been our habit in the past, our outgoing chairman, Pierre Bultynck, has continued his duties until the end of the calendar year, and in the name of all the Subcommission, I like to express our warmest thanks to him for all his efforts, his enthusi- asm for our tasks, his patience with the often too slow progress of research, and for the humorous, well organized and skil- ful handling of our affairs, including our annual meetings. At the same time I like to thank all our outgoing Titular Members for their partly long-time service and I express my hope that they will continue their SDS work with the same interest and energy as Corresponding Members. The new ICS rules require a rather constant change of voting members and the change from TM to CM status should not necessarily be taken as an excuse to adopt the lifestyle of a “Devonian pensioner”. I see no reason why constantly active SDS members shouldn´t become TM again, at a later stage. On the other side, the rather strong exchange of voting members should bring in some fresh ideas and some shift towards modern stratigraphical tech- niques.

    MIDDLE- UPPER DEVONIAN DEPOSITIONAL AND BIOTIC EVENTS IN WESTERN NEW YORK Gordon C. Baird, Dept. of Geosciences, SUNY-Fredonia, Fredonia, NY 14063; D. Jeffrey Over, Dept. of Geological Sciences, SUNY-Geneseo, Geneseo, NY 14454; William T. Kirch gasser, Dept. of Geology, SUNY-Potsdam, Potsdam, NY 13676; Carlton E. Brett, Dept. of Geology, Univ. of Cincinnati, 500 Geology/Physics Bldg., Cincinnati, OH 45221 INTRODUCTION The Middle and Late Devonian succession in the Buffalo area includes numerous dark gray and black shale units recording dysoxic to near anoxic marine substrate conditions near the northern margin of the subsiding Appalachian foreland basin. Contrary to common perception, this basin was often not stagnant; evidence of current activity and episodic oxygenation events are characteristic of many units. In fact, lag deposits of detrital pyrite roofed by black shale, erosional runnels, and cross stratified deposits of tractional styliolinid grainstone present a counter intuitive image of episodic, moderate to high energy events within the basin. We will discuss current-generated features observed at field stops in the context of proposed models for their genesis, and we will also examine several key Late Devonian bioevents recorded in the Upper Devonian stratigraphic succession. In particular, two stops will showcase strata associated with key Late Devonian extinction events including the Frasnian-Famennian global crisis.

The structural framework of the platform results from the 20 accretion of Archean and Proterozoic terranes during the Pan-African orogeny (750–580 Ma). 21 The Ahnet and Mouydir basins are successively delimited from east to west by the Amguid El 22 Biod, Arak-Foum Belrem, and Azzel Matti arches, bounded by inherited Precambrian sub- 23 vertical fault systems which were repeatedly reactivated or inverted during the Paleozoic.

El género Aulatornoceras comprendía hasta la actualidad un amplio espectro de morfologías y, entre ellas, conchas de especies con perfiles más comprimidos que el resto de formas congenéricas, poseyendo al mismo tiempo ombligos puntifor­ mes. Esta peculiaridad nos induce a pensar que dentro de Aulatornoceras existen al menos dos grupos de especies con diferentes planteamientos ecológicos, por lo que hemos erigido el nuevo subgénero Aulatornoceras (Truyolsceras) , cuyo carác­ ter diagnóstico principal dentro del género es la existencia de ombligos puntifor­ mes. Palabras clave: Arnmonoidea, Tornoceratina, Aulatornoceras (Truyolsoceras) n. subgen., Dev6nico Medio y Superior, Cordillera Cantábrica, Cordillera Ibérica, España. Species included into the genus Aulatornoceras encompass shells with an excesi­ vely wide morphological range. Arnong them, those characterized by a compres­ sed shell with very narrow to occluded umbilicus where adapted to paleoecologi­ cal conditions other than the type-species Aulatornoceras auris and related forms.

Northrop, 1961, pp. 105-112 in: Albuquerque Country, Northrop, S. A.; [ed.], New Mexico Geological Society 12th Annual Fall Field Conference Guidebook, 199 p. This is one of many related papers that were included in the 1961 NMGS Fall Field Conference Guidebook. Annual NMGS Fall Field Conference Guidebooks Every fall since 1950, the New Mexico Geological Society (NMGS) has held an annual Fall Field Conference that explores some region of New Mexico (or surrounding states). Always well attended, these conferences provide a guidebook to participants. Besides detailed road logs, the guidebooks contain many well written, edited, and peer-reviewed geoscience papers. These books have set the national standard for geologic guidebooks and are an essential geologic reference for anyone working in or around New Mexico. Free Downloads NMGS has decided to make peer-reviewed papers from our Fall Field Conference guidebooks available for free download. Non-members will have access to guidebook papers two years after publication. Members have access to all papers. This is in keeping with our mission of promoting interest, research, and cooperation regarding geology in New Mexico. However, guidebook sales represent a significant proportion of our operating budget. Therefore, only research papers are available for download. Road logs, mini-papers, maps, stratigraphic charts, and other selected content are available only in the printed guidebooks.
