Introduction. a Monograph of Yorkshire Carboniferous Polyzoa, Will Be, Speaking Generally, a Monograph of Nearly the Whole of British Species Downloaded from http://pygs.lyellcollection.org/ at University of Iowa on June 25, 2015 68 A MONOGRAPH OF YORKSHIRE CARBONIFEROUS AND PERMIAN POLYZOA. PART I. BY GEORGE ROBERT TINE. I.—Introduction. A monograph of Yorkshire Carboniferous Polyzoa, will be, speaking generally, a monograph of nearly the whole of British species. There are a few forms found elsewhere, which, up to date, I have not detected in my Yorkshire material, but when we consider that only a few samples of our Yorkshire shales have been, as yet, persistently searched for the more minute fossils, we need not be surprised at that. Ordinary fossil collectors in the Limestone districts have secured many examples of Fenestella and Polypora, but the great mass of Carboniferous Polyzoa are small, and apparently insig• nificant, hence it is only those who study microscopic organisms who are brought into contact with the fragments found in shale washings. If the whole of the species, however, are not found in the York• shire Limestones and Shales, the genera are, and to a large extent the fades of the Yorkshire species are peculiar, and there oy merit special recognition. Certainly on this head, I have done justice to Yorkshire examples in the pages of this Journal, but my previous work can only be regarded as a catalogue of the species, and not a monograph. In this higher sense a true monograph should embrace all previous work, and the description of the forms should be full and complete up to date, and the illustrations, superficial and structural, should also be ample. So far as I am aware no attempt has yet been made to give to the scientific world a monograph of British Carbon• iferous forms, and it is only just recently that monographs of American Carboniferous Polyzoa are being brought to the front by the Palaeon• tologists of the various Geological Surveys. The forthcoming Report of the Geological Survey of Illinois will contain twenty-six plates of Cai'boniferous Polyzoa alone, besides seventeen plates of Devonian and Silurian forms, illustrative of species found in the varied strata of the same State. Most of the other papers which Mr. E. 0. Uirich will refer to in his noble work, must be regarded in a similar light Downloaded from http://pygs.lyellcollection.org/ at University of Iowa on June 25, 2015 VINE: CARBONIFEROUS AND PERMIAN POLYZOA. 69 with our own, as scattered fragments only, descriptive or otherwise, of a great and widely distributed Carboniferous fauna, and my desire will be to do for British Polyzoa what the late lamented Dr. Davidson did for the Brachiopoda, to furnish a full and reliable account of all the species known to me in our British rocks, but for the present I confine myself to Carboniferous and Permian Polyzoa.

  • Late Carboniferous Bryozoans from La Hermida, Spain
    Late Carboniferous bryozoans from La Hermida, Spain Andrej Ernst and Elke Minwegen Acta Palaeontologica Polonica 51 (3), 2006: 569-588 Fifteen bryozoan species belonging to thirteen genera have been identified from an outcrop of the Picos de Europa Formation (Moscovian, Upper Carboniferous) at La Hermida in northern Spain. Three species and one genus are new Coscinium hermidensis sp. nov., Cystodictya pustulosa sp. nov., and Cystocladia hispanica gen. et sp. nov. Rhabdomesid bryozoans are the most diverse order with seven species, followed by cystoporids (four species), fenestellids (three species) and trepostomids (one species). Bryozoans with erect branched or reticulate colonies dominate in the studied assemblage; only two species possess encrusting colonies. Together with associated crinoids, the bryozoan assemblage indicates a subtidal environment below the zone of vigorous water movement. The La Hermida bryozoan fauna confirms the Upper Carboniferous age of the Picos de Europa Formation and allows various biogeographical interpretations. All previously known species of the genus Coscinium were reported from the Lower Permian of Russia. Clausotrypa monticola is known from the Lower Permian of Russia and Arctic as well as from the Upper Carboniferous of Carnic Alps (Austria). Rhabdomeson cf. propatulissimum and Penniretepora pseudotrilineata are known from the same level of Italian Carnic Alps. Streblotrypa (Streblascopora ) nikiforovae and Rhombocladia punctata are known from the Upper Carboniferous (Moscovian) of Ukraine. Fistulipora petaloida is known from Kasimovian Stage of Russian Plate. Several other species show connections with North America. Key words: Bryozoa, Cystoporida, Fenestellida, Carboniferous, Picos de Europa Formation, Spain.

Wyse Jackson Department of Geology, Trinity College, Dublin 2, Ireland Ever since the commencement of scientific publication the views of the authors have been available to others to agree with or to find fault with. Without scientific debate it is unlikely that major scientific advancements could have been made. The differences of opinion of a number of scientific combatants have in the past led to long-term animosities. In the field of geology and palaeontology there are a number of well-known instances: James Hutton produced an abstract of his ideas on the history of the Earth in 1785, but was stung into publishing his full-length Theory of the Earth in 1795 following criticism leveled at him by various opponents including the Irishman and chemist Richard Kirwan (McIntyre 1997, Wyse Jackson 1998). The two close-friends and stratigraphers Adam Sedgwick and Roderick Impey Murchison, who together named the Devonian in 1839, ultimately fell-out when the latter’s Silurian encroached on the former’s Cambrian successions (Secord 1986). During the so-called ‘Bone-wars’, that raged in the United States during the late-nineteenth century, Edward Drinker Cope and Othniel Charles Marsh argued over the reconstructions and significance of many dinosaur specimens that each had discovered (Shor 1974, Jaffe 2000).

This is one of many related papers that were included in the 1961 NMGS Fall Field Conference Guidebook. Annual NMGS Fall Field Conference Guidebooks Every fall since 1950, the New Mexico Geological Society (NMGS) has held an annual Fall Field Conference that explores some region of New Mexico (or surrounding states). Always well attended, these conferences provide a guidebook to participants. Besides detailed road logs, the guidebooks contain many well written, edited, and peer-reviewed geoscience papers. These books have set the national standard for geologic guidebooks and are an essential geologic reference for anyone working in or around New Mexico. Free Downloads NMGS has decided to make peer-reviewed papers from our Fall Field Conference guidebooks available for free download. Non-members will have access to guidebook papers two years after publication. Members have access to all papers. This is in keeping with our mission of promoting interest, research, and cooperation regarding geology in New Mexico. However, guidebook sales represent a significant proportion of our operating budget. Therefore, only research papers are available for download. Road logs, mini-papers, maps, stratigraphic charts, and other selected content are available only in the printed guidebooks.

    VOL. 52, PL. IX SMITHSONIAN MISCELLANEOUS COLLECTIONS HENRY NETTELROTH Vol. 52 1908 Smithsonian Miscellaneous Collections Vol. V Quarterly issue Part 2 THE XETTELROTH COLLECTION OF INVERTEBRATE FOSSILS By R. S. BASSLER (With 3 Plates) One of the most important accessions in the division of strati- graphic paleontology during the year 1907 was the collection of the late Henry Nettelroth, acquired jointly by the Smithsonian Institu- tion and the U. S. National Museum from his sons, H. H. Nettel- roth and Dr. Alexander Nettelroth, of Louisville, Kentucky. The registration and installation of these specimens was recently com- pleted, and it seemed in order, as well as very desirable on account of Mr. Nettelroth's work in science and of the valuable nature of his collection, to publish an article upon the subject. The collection is composed entirely of invertebrate fossils, mainly from the Silurian and Devonian strata of Indiana and Kentucky, although many other American as well as foreign localities are represented. The total number of specimens is rather small compared with the number of species represented, the collection comprising about 8,000 specimens, registered under nearly 1,000 entries; but all of the material is the best that could be had. Mr. Nettelroth prided himself upon the fact that his cabinet contained only choice specimens, representing years of careful selection. Imperfect material was retained only when it showed something of scientific interest. In exchanging. Air. Nettelroth also insisted upon a few good specimens rather than numerous poor representatives of a species. Likewise he paid par- ticular attention to a class of fossils, the mollusca, which is seldom well represented in the cabinets of even the best collectors.

  • Paleobiogeographic Associations Among Mississippian Bryozoans
    PALEOBIOGEOGRAPHIC ASSOCIATIONS AMONG MISSISSIPPIAN BRYOZOANS BY Ryan FitzGerald Morgan A THESIS Submitted to Michigan State University in partial fulfillment of the requirements for the degree of MASTER OF SCIENCE Geological Sciences 2010 i ABSTRACT PALEOBIOGEOGRAPHIC ASSOCIATIONS AMONG MISSISSIPPIAN BRYOZOANS BY Ryan FitzGerald Morgan Area cladograms produced by parsimony analysis of endemicity coupled with seriation, paired group cluster, principal coordinates, and detrended correspondence analyses demonstrate endemic associations of Mississippian-age bryozoans. These methods identified three major biogeographic associations (North America I, North America II, and Old World Realms), and nine minor associations (Waverly, Keokuk, Warsaw, Burlington, St. Louis, Chester, Tethys I, Tethys II, Russia, Kazakhstan-Siberia Provinces). These associations, along with latitudinal diversity gradients, provide support for an early closure of the tropical seaway (Rheic Ocean) that existed between Laurussia and Gondwana, along with support for faunal shifts due to the onset of Gondwanan glaciation and the restriction of North American faunas from the more eastern Tethyan faunas. ii DEDICATION This thesis is dedicated to my mother, Christena Morgan, in recognition of her encouragement, support, and gift of an inquisitive mind. iii ACKNOWLEDGEMENTS I would like to first acknowledge Dr Robert L Anstey, both for all the help and guidance he has supplied over the course of my education and this thesis, and also for providing the push to engage in this field of study. I would also like to acknowledge my wife, Christina L Gurski, who has spent many long hours listening to me ramble about all sorts of ideas, and for providing much needed distraction from this thesis; if not for her it would have been completed ages ago.

  • 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).
