    Bryozoan Studies 2019

    BRYOZOAN STUDIES 2019 Edited by Patrick Wyse Jackson & Kamil Zágoršek Czech Geological Survey 1 BRYOZOAN STUDIES 2019 2 Dedication This volume is dedicated with deep gratitude to Paul Taylor. Throughout his career Paul has worked at the Natural History Museum, London which he joined soon after completing post-doctoral studies in Swansea which in turn followed his completion of a PhD in Durham. Paul’s research interests are polymatic within the sphere of bryozoology – he has studied fossil bryozoans from all of the geological periods, and modern bryozoans from all oceanic basins. His interests include taxonomy, biodiversity, skeletal structure, ecology, evolution, history to name a few subject areas; in fact there are probably none in bryozoology that have not been the subject of his many publications. His office in the Natural History Museum quickly became a magnet for visiting bryozoological colleagues whom he always welcomed: he has always been highly encouraging of the research efforts of others, quick to collaborate, and generous with advice and information. A long-standing member of the International Bryozoology Association, Paul presided over the conference held in Boone in 2007. 3 BRYOZOAN STUDIES 2019 Contents Kamil Zágoršek and Patrick N.

  • A Succession of Depositional Environments in the Mid-Ordovician Section at Crown Point, New York

    A Succession of Depositional Environments in the Mid-Ordovician Section at Crown Point, New York

    A SUCCESSION OF DEPOSITIONAL ENVIRONMENTS IN THE MID-ORDOVICIAN SECTION AT CROWN POINT, NEW YORK Brewster Baldwin 1 and Lucy E. Harding Department of Geology Middlebury College, Middlebury, Vermont 05753 Introduction The Crown Point section, exposed at the Crown Point State Historic Site, is a wonderful place for using fossils, sedimentary textures and structures, and lithologies to interpret changing environments of deposition. Formations exposed in the 120 meter (400 feet) thick section include the Crown Point, Valcour, Orwell, and Glens Falls limestones, deposited between about 458-444 million years ago on the eastern margin of North America. The rocks record the onset of the continent-arc collision known as the Taconic Orogeny. The lower half of the section records deposition on a slowly subsiding, passive continental margin. The upper half records a swift transition to deeper water environments as the continental margin entered the subduction zone. At Crown Point these rocks comprise a homoclinal section dipping about 8 degrees to the west-northwest. The Middlebury College geology department uses the Crown Point section as a field exercise for both first- and second-year geology students. Their field trip as well as yours consists of a walking tour beginning about 500 meters southeast of Fort Crown Point, heading towards and through the Fort, and then continuing west for about 200 meters along the Lake Champlain shoreline. We will visit most of the lettered stations shown on the index and air photo maps (Figs. 1 and 2). The lettered stations are also shown on the detailed columnar section (Fig. 3) and the student columnar section (Fig.

    A New Species of Conchicolites (Cornulitida, Tentaculita) from the Wenlock of Gotland, Sweden

    Estonian Journal of Earth Sciences, 2014, 63, 3, 181–185 doi: 10.3176/earth.2014.16 SHORT COMMUNICATION A new species of Conchicolites (Cornulitida, Tentaculita) from the Wenlock of Gotland, Sweden Olev Vinna, Emilia Jarochowskab and Axel Munneckeb a Department of Geology, University of Tartu, Ravila 14A, 50411 Tartu, Estonia; [email protected] b GeoZentrum Nordbayern, Fachgruppe Paläoumwelt, Universität Erlangen-Nürnberg, Loewenichstr. 28, 91054 Erlangen, Germany Received 2 June 2014, accepted 4 August 2014 Abstract. A new cornulitid species, Conchicolites crispisulcans sp. nov., is described from the Wenlock of Gotland, Sweden. The undulating edge of C. crispisulcans sp. nov. peristomes is unique among the species of Conchicolites. This undulating peristome edge may reflect the position of setae at the tube aperture. The presence of the undulating peristome edge supports the hypothesis that cornulitids had setae and were probably related to brachiopods. Key words: tubeworms, tentaculitoids, cornulitids, Silurian, Baltica. INTRODUCTION Four genera of cornulitids have been assigned to Cornulitidae: Cornulites Schlotheim, 1820, Conchicolites Cornulitids belong to encrusting tentaculitoid tubeworms Nicholson, 1872a, Cornulitella (Nicholson 1872b) and and are presumably ancestors of free-living tentaculitids Kolihaia Prantl, 1944 (Fisher 1962). The taxonomy (Vinn & Mutvei 2009). They have a stratigraphic range of Wenlock cornulitids of Gotland (Sweden) is poorly from the Middle Ordovician to the Late Carboniferous studied, mostly due to their minor stratigraphical (Vinn 2010). Cornulitid tubeworms are found only in importance. normal marine sediments (Vinn 2010), and in this respect The aim of the paper is to: (1) systematically they differ from their descendants, microconchids, which describe a new species of cornulitids from the Wenlock lived in waters of various salinities (e.g., Zatoń et al.
