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. Individual copies may be obtained from the Smithsonian Institution Press as long as stocks are available.

  • Taxonomy, Phylogeny and Biogeography of the Late Famennian Conodont Genus Mashkovia
    Journal of Micropalaeontology, 17: 119-124. 0262-821)</98$10.00 0 1998 British Micropalaeontological Society. 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.

BALSTER Micropaleontological studies in the Iowa geologic section have been gaining impetus in the past few years, but no previous attempt has been made to assemble the accumulated information. The value of microfossils in defining and correlating stratigraphic units is generally accepted. This paper is a compilation of existing in­ formation in an attempt to establish preliminary fauna! zones. Where diagnostic fossils for the various zones were not indicated by the original author we have chosen them according to relative abundance and unique occurrence, if possible. In some instances inadequate data limit the application of this method, and require listing of a larger part of the assemblage than would otherwise be necessary.

Aldridge Department of Geology, University of Leicester, University Road, Leicester LE1 7RH, UK Shunxin Zhang Canada – Nunavut Geoscience Office, 626 Tumit Plaza, Suite 202, PO Box 2319, Iqaluit, Nunavut, Canada X0A 0H0 SYNOPSIS Little attention has been paid to the suprageneric classification for conodonts and ex- isting schemes have been formulated without attention to homology, diagnosis and definition. We propose that cladistics provides an appropriate methodology to test existing schemes of classification and in which to explore the evolutionary relationships of conodonts. The development of a multi- element taxonomy and a concept of homology based upon the position, not morphology, of elements within the apparatus provide the ideal foundation for the application of cladistics to conodonts. In an attempt to unravel the evolutionary relationships between ‘complex’ conodonts (prioniodontids and derivative lineages) we have compiled a data matrix based upon 95 characters and 61 representative taxa. The dataset was analysed using parsimony and the resulting hypotheses were assessed using a number of measures of support. These included bootstrap, Bremer Support and double-decay; we also compared levels of homoplasy to those expected given the size of the dataset and to those expected in a random dataset.

  • Evolutionary Roots of the Conodonts with Increased Number of Elements in the Apparatus Jerzy Dzik Instytut Paleobiologii PAN, Twarda 51/55, 00-818 Warszawa, Poland
    Earth and Environmental Science Transactions of the Royal Society of Edinburgh, 106, 29–53, 2015 Evolutionary roots of the conodonts with increased number of elements in the apparatus Jerzy Dzik Instytut Paleobiologii PAN, Twarda 51/55, 00-818 Warszawa, Poland. Wydział Biologii Uniwersytetu Warszawskiego, Aleja Z˙ wirki i Wigury 101, Warszawa 02-096, Poland. Email: [email protected] ABSTRACT: Four kinds of robust elements have been recognised in Amorphognathus quinquira- diatus Moskalenko, 1977 (in Kanygin et al. 1977) from the early Late Ordovician of Siberia, indicat- ing that at least 17 elements were present in the apparatus, one of them similar to the P1 element of the Early Silurian Distomodus. The new generic name Moskalenkodus is proposed for these conodonts with a pterospathodontid-like S series element morphology. This implies that the related Distomodus, Pterospathodus and Gamachignathus lineages had a long cryptic evolutionary history, probably ranging back to the early Ordovician, when they split from the lineage of Icriodella, having a duplicated M location in common. The balognathid Promissum, with a 19-element apparatus, may have shared ancestry with Icriodella in Ordovician high latitudes, with Sagittodontina, Lenodus, Trapezognathus and Phragmodus as possible connecting links. The pattern of the unbalanced contri- bution of Baltoniodus element types to samples suggests that duplication of M and P2 series elements may have been an early event in the evolution of balognathids. The proposed scenario implies a profound transformation of the mouth region in the evolution of conodonts. The probable original state was a chaetognath-like arrangement of coniform elements; all paired and of relatively uniform morphology.
