A New Species of the Conodont Genus Siphonodella Branson & Mehl
Estonian Journal of Earth Sciences, 2017, 66, 4, 188–192 https://doi.org/10.3176/earth.2017.15 A new species of the conodont genus Siphonodella Branson & Mehl (late Tournaisian) Andrey V. Zhuravlev Institute of Geology Komi SC, UrB RAS, Pervomayskaya 54, 167000 Syktyvkar, Russia; [email protected] Received 3 April 2017, accepted 6 June 2017, available online 16 October 2017 Abstract. A new upper Tournaisian (Lower Carboniferous) siphonodellid conodont species Siphonodella carinata n. sp. is described. The material comes from the shallow-water carbonate sediments of the Pechora Swell (Timan-Pechora region or NE of European Russia). The co-occurrence of conodonts Hindeodus cristulus (Youngquist & Miller), Bispathodus stabilis (Branson & Mehl) Morphotype 1, Polygnathus longiposticus Branson & Mehl and Pseudopolygnathus nodomarginatus (Branson) suggests the late Tournaisian (Lower Siphonodella crenulata Zone) age of the deposits. Morphologically the new species is similar to Siphonodella semichatovae Kononova & Lipnjagov and S. ludmilae Zhuravlev & Plotitsyn, but differs in possessing three rostral ridges at the late stages of ontogeny and Class III symmetry. The presence of the shallow-water siphonodellids Siphonodella bella Kononova & Migdisova and S. quasinuda Gagiev, Kononova & Pazuhin in the upper part of the Tournaisian is detected for the first time. Key words: Conodonta, new species, Siphonodella carinata n. sp., Lower Carboniferous, Tournaisian. INTRODUCTION platform and a wide pseudokeel or depressed keel at the aboral side of Pa elements. Traditionally species of the genus Siphonodella are used The shallow-water siphonodellids of the Chinese for biostratigraphy of the lower part of the Tournaisian branch appeared in the earliest Tournaisian and ranged (Sandberg et al. 1978; Ji 1985; Ji & Ziegler 1992; up to the late Tournaisian (Ji & Ziegler 1992). -

Collier of Invertebrate Fossils: Conodonta SMITHSONIAN CONTRIBUTIONS TO PALEOBIOLOGY NUMBER 9 SERIAL PUBLICATIONS OF THE SMITHSONIAN INSTITUTION The emphasis upon publications as a means of diffusing knowledge was expressed by the first Secretary of the Smithsonian Institution. In his formal plan for the Insti tution, Joseph Henry articulated a program that included the following statement: "It is proposed to publish a series of reports, giving an account of the new discoveries in science, and of the changes made from year to year in all branches of knowledge." This keynote of basic research has been adhered to over the years in the issuance of thousands of titles in serial publications under the Smithsonian imprint, com mencing with Smithsonian Contributions to Knowledge in 1848 and continuing with the following active series: Smithsonian Annals of Flight Smithsonian Contributions to Anthropology Smithsonian Contributions to Astrophysics Smithsonian Contributions to Botany Smithsonian Contributions to the Earth Sciences Smithsonian Contributions to Paleobiology Smithsonian Contributions to Zoology Smithsonian Studies in History and Technology In these series, the Institution publishes original articles and monographs dealing with the research and collections of its several museums and offices and of profes sional colleagues at other institutions of learning. These papers report newly acquired facts, synoptic interpretations of data, or original theory in specialized fields. These publications are distributed by mailing lists to libraries, laboratories, and other in terested institutions and specialists throughout the world.

Taxonomy, Phylogeny and Biogeography of the Late Famennian Conodont Genus Mashkovia

Taxonomy, phylogeny and biogeography of the late Famennian conodont genus Mashkovia ZDZISLAW BELKA Geologisch-Palaontologisches Institut, Universitat Tubingen, Sigwartstr. 10, D - 72076 Tiibingen, Germany. ABSTRACT - Mashkovia is one of the provincial conodonts which developed during late Famennian time in the cratonic regions of Russia. In this study, the taxonomy of this genus is revised, based on diagnostic characters of the Pa elements, such as the morphology of the anterior part of the platform, the ornamentation and the shape of the secondary keels. As a consequence, four species, including M. silesiensis n. sp. now discovered in Upper Silesia of southern Poland, are distinguished. The apparent absence of Mashkovia from North America, Variscan Europe, Australia and Africa cannot be simply explained by using temperature or other global climatic factors as a reason for the provincialism. Currents and/or local palaeoecologic factors were probably more important in controlling the distribution of these conodonts. J. Micropalaeontol. 17(2): 119-124, December 1998. INTRODUCTION This paper summarizes the present knowledge of the late Famennian conodont genus Mashkovia, which is a real rarity among the Devonian conodont elements. Up to now, only about 80 specimens of Pa elements of Mashkovia have been found throughout the world. The multi-element composition of its apparatus is unknown. As at present conceived, Mashkovia contains four species, three of which, M. simakovi (Gagiev, 1979), M. similis (Gagiev, 1979), and M. tamarae Kononova & Pazuhin, 1983, are known exclusively from Russia. The fourth one, M. silesiensis n. -

From the Lower Carboniferous of Belgium, and International Correlation Using Taphrognathids

PURNELL1, PETER H. VON BITTER2 & ERIC GROESSENS3 1Department of Geology, University of Leicester, University Road, Leicester LE1 7RH, UK (e-mail: [email protected]) 2Department of Palaeobiology, Royal Ontario Museum and Department of Geology, University of Toronto, 100 Queens Park, Toronto, Ontario, Canada, M5S 2C6 3Service Géologique de Belgique, Rue Jenner, 13, B-1000 Bruxelles, Belgium ABSTRACT – Lower Carboniferous conodont faunas from shallow shelf and more offshore settings have few taxa in common and correlation is difficult. Consequently, reports of shallow shelf taphrognathid conodonts and indications that the Taphrognathus transatlanticus Range Zone may be recognizable in Lower Carboniferous sequences in Belgium (Conil et al., 1991) are potentially significant for international correlation using conodonts. Here we present a review of the usefulness of taphrognathid conodonts in international correlation and a brief summary of the current state of their taxonomy. Taphrognathus transatlanticus von Bitter & Austin, 1984 cannot be accommodated within Taphrognathus Branson & Mehl, 1941 and, until a new genus is erected, it is best referred to as aff. Taphrognathus transatlanticus. The status of T. rhodesi as a distinct species is uncertain. The affinities of T. alaskensis are currently obscure, but we strongly doubt that it is a species of Taphrognathus. Regarding Belgian taphrognathids, examination of specimens from the collection reported by Conil et al. (1991) reveals that Taphrognathus carinatus (Higgins & Varker, 1982) is present. This extends the geographical range of T. -
(Upper Devonian) Conodont Zonation: Revised Global Standard
Famennian (Upper Devonian) conodont zonation: revised global standard CLAUDIA SPALLETTA, MARIA CRISTINA PERRI, D. JEFFREY OVER & CARLO CORRADINI The revision of the Famennian part of the “Late Devonian Standard Conodont Zonation” is based on the in-equivalence between biozones and time, and the rejection of the presumed single phyletic concept on which the previous zonation was based. It is also intended to simplify the zonation, eliminating the zonal groups named after only one taxon, and biozones that are defined by a Last Appearance Datum (LAD). The proposed revision is largely based on the zonation proposed by Ziegler and Sandberg (1990) and is for the most part correlatable using the same zonal markers. Modifica- tions have only been made when strictly necessary, as the aim of the proposal is to maintain the stability of over 50 years of studies. The 22 zones constituting the revised zonation are defined by the First Appearance Datum (FAD) of species or subspecies that have a well-established stratigraphic range and wide geographic distribution. Each zone is named after the taxon for which the FAD defines the lower boundary. For each zone an association of other species useful for its identification is listed. • Key words: conodonts, Upper Devonian, Famennian, biostratigraphy, biozonation.
