Africa, Scripta Geol., 69 (1983) On some occurrences of Diplognathodus in Carboniferous strata of Western Europe and North Africa M. van den Boogaard Boogaard, M. van den. On some occurrences of Diplognathodus in Carboniferous strata of Western Europe and North Africa. - Scripta Geol., 69: 19-29, 1 fig., 1 pl., October 1983. The occurrence is reported of Diplognathodus coloradoensis, D. orphanus and D. ellesmerensis in some localities in Western Europe and one locality in North Afri- ca.

Introduction 19 Localities 20 Palaeontology 23 Concluding remarks 25 References 27 Introduction Species of the genus Diplognathodus may be useful for stratigraphie correlation of Carboniferous strata because some of them are probably stratigraphically short-ranging (e.g. D. coloradoensis according to Landing & Wardlaw, 1981, pp. 1255-1256). Because still little is known about the distribution of représentants of the genus outside North America I thought it useful to relate the few occur• rences of D. coloradoensis, D. orphanus and D. ellesmerensis I encountered during my investigation of Carboniferous limestones from Western Europe and North Africa. 20 v.d.

Marshall _________________________ Dr. Anthony Walton Date Defended: 07/25/2011 The Thesis committee for Vincent Nowaczewski certifies that this is the approved version of the following thesis: Biomarker and Paleontological Investigations of the Late Devonian Extinctions, Woodford Shale, Southern Oklahoma _________________________________ Chairperson: Dr. Alison Olcott Marshall Date Approved: 08/18/2011 ii Abstract The Late Devonian extinctions at the Frasnian-Famennian (F-F) boundary and the Devonian-Carboniferous (D-C) boundary were investigated in the Woodford Shale of south- central Oklahoma with organic geochemical, bulk geochemical, petrographic, and paleontologic techniques. Three sections were collected, two outcrop sections in the Arbuckle Mountains, and one measured core section from the western Arkoma basin. The ratios of extractable biomarkers including steranes, indicative of differing eukaryote input, and pristane/phytane, indicative of oxic or anoxic depositional conditions, display different responses to the F-F boundary and the D-C boundary, as do the abundances of isorenieratane, indicative of photic zone anoxia, and gammacerane, indicative of water column stratification. The ratio of C29 steranes to C27 and C28 steranes are higher in abundance around the F-F boundary and lower in abundance around the D- C boundary, indicating different algal communities at each extinction. -

Gonchar Str. 55-b, 01601 Kiev, Ukraine ___________________________________________________________________________ A major criterion for selecting a Global Stratotype Section and Point (GSSP) is to demonstrate depositional continuity. Depositional continuity is most often accepted where there is a transitional morphocline from an ancestral species to its descendent. The GSSP is then selected to correspond with the phylogenetic first occurrence of the descendent species. Ideally, strata elsewhere are subsequently correlated with the GSSP using the local first appearance of the descendent species, or by other taxa associated with the GSSP providing supplementary biostratigraphic data. Any other stratigraphic methods can be used for correlation once the GSSP has been ratified by the International Union of Geological Sciences Commission on Stratigraphy. Multiple conodont lineages with complete transitional morphologies characterize the Bashkirian- Moscovian boundary interval in the Naqing section. The presence of all these chronoclines through the section demonstrates depositional continuity at Naqing, and provides numerous possible conodont- based levels available for selecting a basal Moscovian GSSP. -
Ian, and the Early Upper Devonian Some Icriodus Species Such As
©Geol. Bundesanstalt, Wien; download unter www.geologie.ac.at ian, and the early Upper Devonian some Icriodus species such as /. fusiformis, I. culicellus, I. rectiro- stratus, I. retrodepressus, I. regularicrescens, I. obliquimarginatus and /. subterminus have a wide or so metimes nearly cosmopolite dispersion in different magnafacies areas (type Ardenno-Rhenish and Her- cynian-Bohemian) and there is no marked difference in the earliest occurrence of each species. This means that the geographical dispersion of at least some Icriodus species was due primarily to good com munication seaways which could be modified in the course of time and not to very specialised local fa des factors. Having in mind the SEDDON and SWEET model for conodonts, the dominance of Icrio dus in shallow water shelf environment implies no restriction in geographical dispersion. Particularly in this environment, anomalies in the vertical distribution ofPolygnathus taxa, e. g.,-P. serotinus, P. lingui- formis div. subspecies, P. cooperi cooperi can be noticed. Reexamination of Late Pennsylvanian and Early Permian Conodont Apparatuses Using Clustering Techniques. By T. R. CARR Department of Geology and Geophysics, University of Wisconsin, Madison, Wisconsin 53706, USA. Conodont faunas containing easily identified Pa elements assignable to the genera Diplognathodus and Hindeodus have been reported from Upper Pennsylvanian and Lower Permian strata of North Ame rica. If the seximembrate model for the apparatus of each genus is correct, the remaining elements should also be present. However, previous investigators have normally considered ramiform elements which might be assignable to the two genera as attributable to species of either the Idiognathodus— Streptognathodus plexus or Adetognathus. -
Pander Society Newsletter
Pander Society Newsletter S O E R C D I E N T A Y P 1 9 6 7 Compiled and edited by P.H. von Bitter and J. Burke PALAEOBIOLOGY DIVISION, DEPARTMENT OF NATURAL HISTORY, ROYAL ONTARIO MUSEUM, TORONTO, ON, CANADA M5S 2C6 Number 41 May 2009 www.conodont.net Webmaster Mark Purnell, University of Leicester 2 Chief Panderer’s Remarks May 1, 2009 Dear Colleagues: It is again spring in southern Canada, that very positive time of year that allows us to forget our winter hibernation & the climatic hardships endured. It is also the time when Joan Burke and I get to harvest and see the results of our winter labours, as we integrate all the information & contributions sent in by you (Thank You) into a new and hopefully ever better Newsletter. Through the hard work of editor Jeffrey Over, Paleontographica Americana, vol. no. 62, has just been published to celebrate the 40th Anniversary of the Pander Society and the 150th Anniversary of the first conodont paper by Christian Pander in 1856; the titles and abstracts are here reproduced courtesy of the Paleontological Research Institution in Ithica, N.Y. Glen Merrill and others represented the Pander Society at a conference entitled “Geologic Problem Solving with Microfossils”, sponsored by NAMS, the North American Micropaleontology Section of SEPM, in Houston, Texas, March 15-18, 2009; the titles of papers that dealt with or mentioned conodonts, are included in this Newsletter. Although there have been no official Pander Society meetings since newsletter # 40, a year ago, there were undoubtedly many unofficial ones; many of these would have been helped by suitable refreshments, the latter likely being the reason I didn’t get to hear about the meetings. -
From Microfossils to Megafauna: an Overview of the Taxonomic Diversity of National Park Service Fossils
Lucas, S. G., Hunt, A. P. & Lichtig, A. J., 2021, Fossil Record 7. New Mexico Museum of Natural History and Science Bulletin 82. 437 FROM MICROFOSSILS TO MEGAFAUNA: AN OVERVIEW OF THE TAXONOMIC DIVERSITY OF NATIONAL PARK SERVICE FOSSILS JUSTIN S. TWEET1 and VINCENT L. SANTUCCI2 1National Park Service, 9149 79th Street S., Cottage Grove, MN, 55016, [email protected]; 2National Park Service, Geologic Resources Division, 1849 “C” Street, NW, Washington, D.C. 20240, [email protected] Abstract—The vast taxonomic breadth of the National Park Service (NPS)’s fossil record has never been systematically examined until now. Paleontological resources have been documented within 277 NPS units and affiliated areas as of the date of submission of this publication (Summer 2020). The paleontological records of these units include fossils from dozens of high-level taxonomic divisions of plants, invertebrates, and vertebrates, as well as many types of ichnofossils and microfossils. Using data and archives developed for the NPS Paleontology Synthesis Project (PSP) that began in 2012, it is possible to examine and depict the broad taxonomic diversity of these paleontological resources. The breadth of the NPS fossil record ranges from Proterozoic microfossils and stromatolites to Quaternary plants, mollusks, and mammals. The most diverse taxonomic records have been found in parks in the western United States and Alaska, which are generally recognized for their long geologic records. Conifers, angiosperms, corals, brachiopods, bivalves, gastropods, artiodactyls, invertebrate burrows, and foraminiferans are among the most frequently reported fossil groups. Small to microscopic fossils such as pollen, spores, the bones of small vertebrates, and the tests of marine plankton are underrepresented because of their size and the specialized equipment and techniques needed to study them. -
Polychaete Jaw Apparatuses and Scolecodonts from the Upper Devonian of Poland
ACTA PALAEONTOLOGICA POLONICA Vol. XVIII 1973 No.3 HUBERT SZANIAWSKI & RYSZARD M. WRONA POLYCHAETE JAW APPARATUSES AND SCOLECODONTS FROM THE UPPER DEVONIAN OF POLAND Abstract. - From FrasniaJIl strata pierced by the Opole Lubelskie borehole in the sQuth-eaiStel'n Poland, 10 polychaete jaw apparatuses are des'cl'ibed. For these ap paratuses, 7 new ,species aJnd 3 new genera are proposed: Multiprion opolensis n.gen., n.,sp., MochtyeZla kielanae n.s-p., Xanioprion waZliseri In.sp., Processoprion longiproces sus n.gen., n.sp., Polychaetaspis hindei n.sp., Kielanoprion elleri n.sp., and Hinde oprion basalaris In.gen., n.,sp. Moreover, 4 new species and 3 new genera of isolated polychaete jaws are described: Langeites lublinensis n.Sip., Trianguligenys n.gen., Uncinogenys uncinatus n.gen., n.Sip., Serratula minutidentata n.gen., n.sp., and Ser ratula longidentata n.Sip. The problems of taxonomy of fossil polychaetes are discus sed and 'necessity of further application of two independent systematics, one for sC'olecodonts and other for jaw apparatuses, is emrpha,sized. INTRODUCTION Polychaete jaws are among the commonest microfossils in Paleozoic strata, and recent studies show that they are also common in Mesozoic ones. The polychaete jaws have been studied for over a century. A rela tive low biological-cognitive and stratigraphical value of isolated jaws resulted in the fact that little attention was paid to this material. Howe ver, a number of complete polychaete jaw apparatuses found rapidly increases nowadays, mainly due to improvement of extraction techniques. Moreover, recent detail studies on scolecodonts, based on the knowledge of fossil and recent apparatuses, showed that their stratigraphic value was underestimated (Kielan-Jaworowska, 1966; Taugourdeau, 1968; Szaniaw ski, 1970; Jansonius & Craig, 1971). -

ТОЛМАЧЕВА (ВСЕГЕИ) CТРАТИГРАФИЯ И ПАЛЕОНТОЛОГИЯ В НАУЧНОЙ ПРОГРАММЕ 34-й СЕССИИ МЕЖДУНАРОДНОГО ГЕОЛОГИЧЕСКОГО КОНГРЕССА (2012 г., Брисбен, Австралия) Рассматриваются сообщения, связанные с созданием Международной хроностратиграфической шкалы, выбором точек глобальных стратотипов границ (GSSP), обоснованием региональных зо- нальных последовательностей, комплексированием биостратиграфических и хемостратиграфических методов и др. Как показало сравнение с итогами предыдущей 33-й сессии Международного геологи- ческого конгресса (МГК), главным отличием современных палеонтолого-стратиграфических иссле- дований является их направленность на реконструкцию климатических особенностей геологического прошлого, оценку влияния палеоклиматов на биоту и характер осадконакопления. Обобщены доклады на секциях и заседаниях комиссий по системам, в которых авторы принимали непосредственное участие, а также дан аналитический обзор тезисов докладов 34-й сессии МГК. Ключевые слова: стратиграфия, палеонтология, 34-я сессия МГК. The main tendencies in modern stratigraphy and paleontology were discussed in the specialized sessions and meetings of the Stratigraphic Subcommissions, as well as in presentations of related sciences. Present review includes presentations connected with the creation of the International Stratigraphic Scale, proposition of the Global Stratigraphic Sections and Points (GSSP), compiling of the regional zonal successions, integration of methods of biostratigraphy and chemostratigraphy and many others. In comparison with previous 33th IGC, 2008, the modern paleontological and stratigraphic studies are different in intensification of investigations targeting the reconstruction of climatic features of the past, influence of paleoclimates to biota and sedimentation. The review is based both on synthesis of sessions and Subcommission meetings presentations where the authors took part and analytic review of the Abstract volume of 34th IGC. Key words: stratigraphy, paleontology, 34th IGC. -

[email protected] ABSTRACT This paper analyzes and describes a fi rst occurrence of the conodonts Ellisonia, Gondolella and Ubinates in Amazonas Basin, North of Brazil. The recovered material comes from two outcrops along the Tapajos River and from a limestone quarry of Itaituba Formation, whose levels are in- cluded in the Itaituba Formation, with a Pennsylvanian age. Those conodonts are relevant paleoecological indicators of water depth, salinity and environmental energy and have implications in the Late Carboniferous to Triassic biostratigraphy. The fossil remains represent M and S conodont elements, associated to Pa elements of the Idiognathodus, Idiognathoides, Neognathodus, Adetognathus, Hindeodus and Diplognathodus genus. Key words: conodonts, Amazonas Basin, Itaituba Formation, Pennsylvanian.

Burke DEPARTMENT OF NATURAL HISTORY (PALAEOBIOLOGY SECTION), ROYAL ONTARIO MUSEUM, TORONTO, ONTARIO, CANADA M5S 2C6 Number 38 June 2006 www.conodont.net CHIEF PANDERER’S REMARKS Dear Conodont Colleagues: A year has gone by since I last communicated like this, and I’m pleased (and relieved) that another Pander Society Newsletter is ready to ‘go’. Thank you for having sent in your reports and questionnaires; without your willingness to going through a bit of pain there would be no Pander Society Newsletter, and our communications would be the poorer. I am very grateful to compiler and editor Joan Burke (Toronto) and webmaster Mark Purnell (Leicester) for their dedication and ongoing interest; they have helped me greatly and continue to make me look better than I really am, particularly in a time of personal and professional transition. You, the Pander Society membership, continue to ‘re-invent’ and apply conodonts in startling new ways. Some of this re-invention was seen at the Pander Society Symposium in Harrisburg, Pennsylvania, where on March 20-22, 2006 our (mostly) North American members focused on Conodonts & Sequence Stratigraphy. Looking ahead, the programme of ICOS 2006 on July 12-30/ 2006 in Leicester, England, promises not only to surprise and delight, but looks remarkably diverse and imaginative. Christian Pander, would, on the 150th anniversary of the publication of his major conodont study, no doubt be enormously impressed and pleased with the innovativeness and progress of his intellectual grandchildren. My best wishes to all of you. -
