The Carboniferous Evolution of Nova Scotia
Downloaded from http://sp.lyellcollection.org/ by guest on September 27, 2021 The Carboniferous evolution of Nova Scotia J. H. CALDER Nova Scotia Department of Natural Resources, PO Box 698, Halifax, Nova Scotia, Canada B3J 2T9 Abstract: Nova Scotia during the Carboniferous lay at the heart of palaeoequatorial Euramerica in a broadly intermontane palaeoequatorial setting, the Maritimes-West-European province; to the west rose the orographic barrier imposed by the Appalachian Mountains, and to the south and east the Mauritanide-Hercynide belt. The geological affinity of Nova Scotia to Europe, reflected in elements of the Carboniferous flora and fauna, was mirrored in the evolution of geological thought even before the epochal visits of Sir Charles Lyell. The Maritimes Basin of eastern Canada, born of the Acadian-Caledonian orogeny that witnessed the suture of Iapetus in the Devonian, and shaped thereafter by the inexorable closing of Gondwana and Laurasia, comprises a near complete stratal sequence as great as 12 km thick which spans the Middle Devonian to the Lower Permian. Across the southern Maritimes Basin, in northern Nova Scotia, deep depocentres developed en echelon adjacent to a transform platelet boundary between terranes of Avalon and Gondwanan affinity. The subsequent history of the basins can be summarized as distension and rifting attended by bimodal volcanism waning through the Dinantian, with marked transpression in the Namurian and subsequent persistence of transcurrent movement linking Variscan deformation with Mauritainide-Appalachian convergence and Alleghenian thrusting. This Mid- Carboniferous event is pivotal in the Carboniferous evolution of Nova Scotia. Rapid subsidence adjacent to transcurrent faults in the early Westphalian was succeeded by thermal sag in the later Westphalian and ultimately by basin inversion and unroofing after the early Permian as equatorial Pangaea finally assembled and subsequently rifted again in the Triassic. -

Is described. The teeth consist of few relatively large, thtck, roughly triangular lamellae. He-interpretation of the teeth structure of the oldest known echlnolds - Upper Ordovician Autechtnus and Ecttnechtnus Is pre sented. It is suggested that their teeth also belong to the flat, ollgolamellar type and have been hitherto wrongly assigned to the grooved type.

Wanda Jesionek-Szymanska, Zaklad Paleobiologii, Polska Akademia Nauk, At 2wirki i Wigury 93, 02-089 Warszawa, Poland. Received: De cember 1978. INTRODUCTION In spite of the great importance of the echinoid teeth morphology in the classification of echinoids, the role of fossil material in this matter has been until now insignificant. This is particularly true of the Paleozoic echinoids which generally are assigned to the "grooved" type. The "serrate" type of teeth has also been reported from the Late Paleozoic deposits (Jackson 1912, Bindemann 1938) but without entering into details and interpretation of this structure. -
Chapter 5. Paleozoic Invertebrate Paleontology of Grand Canyon National Park
Chapter 5. Paleozoic Invertebrate Paleontology of Grand Canyon National Park By Linda Sue Lassiter1, Justin S. Tweet2, Frederick A. Sundberg3, John R. Foster4, and P. J. Bergman5 1Northern Arizona University Department of Biological Sciences Flagstaff, Arizona 2National Park Service 9149 79th Street S. Cottage Grove, Minnesota 55016 3Museum of Northern Arizona Research Associate Flagstaff, Arizona 4Utah Field House of Natural History State Park Museum Vernal, Utah 5Northern Arizona University Flagstaff, Arizona Introduction As impressive as the Grand Canyon is to any observer from the rim, the river, or even from space, these cliffs and slopes are much more than an array of colors above the serpentine majesty of the Colorado River. The erosive forces of the Colorado River and feeder streams took millions of years to carve more than 290 million years of Paleozoic Era rocks. These exposures of Paleozoic Era sediments constitute 85% of the almost 5,000 km2 (1,903 mi2) of the Grand Canyon National Park (GRCA) and reveal important chronologic information on marine paleoecologies of the past. This expanse of both spatial and temporal coverage is unrivaled anywhere else on our planet. While many visitors stand on the rim and peer down into the abyss of the carved canyon depths, few realize that they are also staring at the history of life from almost 520 million years ago (Ma) where the Paleozoic rocks cover the great unconformity (Karlstrom et al. 2018) to 270 Ma at the top (Sorauf and Billingsley 1991). The Paleozoic rocks visible from the South Rim Visitors Center, are mostly from marine and some fluvial sediment deposits (Figure 5-1). -

KEY, Jr. 2 1 Department of Geology, Trinity College, Dublin 2, Ireland 2 Department of Earth Sciences, Dickinson College, Carlisle, PA 17013, USA * Corresponding author e-mail: [email protected] SUMMARY - Epizoic bryozoans on cephalopods through the Phanerozoic: a review - Cephalopods have a long geological record and have been utilised by many encrusting organisms as suitable substrates on which to settle and grow. Living cephalopods, dead floating shells, and those lying on the seabed have been encrusted by bryozoans since the Ordovician; these records are reviewed here. Encrusta- tion by bryozoans declined through the Palaeozoic and into the Mesozoic, and few examples of encrustation of modern nautiloids and coleoids have been reported. The patterns of encrustation provides valuable information, firstly, on the palaeobiology of the hosts and the epizoan: some are obligate, but many appear accidental, and secondly, on the sedimentological conditions at the time of fouling of dead shells. Bryozoan-cephalopod interactions may additionally provide valuable data on present and past drifting patterns of shells, and on the palaeo- and biogeographic influences on bryozoan settlement on cephalopods. RIASSUNTO - Briozoi epizoici su cefalopodi attraverso il Fanerozoico: una rassegna - I cefalopodi hanno una lunga documentazione geologica e sono stati utilizzati da molti organimi incrostanti come substrati disponibili su cui impiantarsi e crescere.

Department of Geography, Geology, and Environmental Science, University of Colorado, Denver, 80217 4. Department of Earth Sciences, Denver Museum of Nature and Science, Denver, Colorado 80205 ABSTRACT Middle Pennsylvanian (latest Atokan) strata in the Minturn Formation of north-central Colorado have yielded new specimens of echinoderms, which have not been previously described from the area. Eretmocrinus sawdoi, new species, is the first batocrinid known from the Pennsylvanian. The Batocrinidae (a family of camerate crinoids) were previously thought to have become extinct during the Mississippian. A probable codiacrinid and an unidentified, upflared, infrabasal circlet are additions to the Minturn crinoid fauna. These specimens show that the crinoid fauna is more diverse than previously thought. New speci- mens of Ulocrinus rockymontanus Strimple and Moore, 1973, Aglaocrinus magnus (Strimple, 1949), and the columnal taxon Pentaridica pentagonalis Moore and Jeffords, 1968, provide new morphological infor- mation. Additional specimens of echinoid plates and spines have also been recovered from the Minturn Formation. They are assigned to Archaeocidaris ourayensis Girty, 1903, Archaeocidaris triplex White, 1881, and Archaeocidaris cratis White, 1876. These specimens come from three thin marine intervals that are overlain and underlain by coarse fluvial and marginal marine deposits. They were recovered from shale and limestone beds that interfinger with sandstone and shale beds. -

The Echinoderms Newsletterl NO.4. December 1972 Prepared in the Department of Invertebrate Zoology (Echinoderms), National Museum of Natural History, Smithsonian Institution, Washington, D. C. 20560 U.S.A. During the past year, we have spent much of our spare time in organizing the Echinoderms Conference, which was held in this Museum durina early September. Since September, we have tried to catch up with the many things we had neglected; one of these was the Newsletter. The present Newsletter contains the usual sections, including curre,,! research projects, recent publications, recent theses, requests, and additions and corrections to the Directory of Specialists. As always, we urge you to complete and return to us the last page of this Newsletter (see p.32). David L. Pawson Maureen E. Downey 'The Echinoderms Newsletter is not intended to be part of the scientific literature, and should not be cited, abstracted, or reprinted as a published document. l 2 Notes and News Most of you will be aware that the First International Congress of Systematic and Evolutionary Biology will be held in Bou1dert Colorado on August 4-12, 1973. The latest brochure (ICSEB Brochure No.2) states that if ten or more scientists have a common interest they will be given a time and place to meet on an informal basis during ICSEB. Those willing to organize such special interest sessions are asked to contact Dr. Doris Love or Dr. David Rogerst University of Coloradot Boulder Co10rado to make a reservation. t t Perhaps some may wish to discuss some aspects of echinoderm evolution or biology at ICSEB?
