(2017) - Shell microstructures in Lopingian brachiopods: implications for fabric evolution and calcification. Riv. It. Paleontol. Strat., 123(3): 541-560. Keywords: Rhynchonelliformea; Strophomenata; biomineralization; taxonomy; columnar layer. Abstract. The study of the shell microstructure of brachiopods is fundamental to understand their evolu- tionary history and their biomineralization process. Here, species of forty Lopingian brachiopods genera, represen- tative of twenty-seven different families, are investigated using the Scanning Electron Microscope. The investiga- ted specimens come from different paleogeographic localities in the Palaeotethys/Neotethys oceans. The studied brachiopods show a large variability of the shell fabric, which is mainly related to the organization of its structural units: laminae, fibers and columns, possibly crossed by pseudopunctae or punctae. For the Strophomenata, the laminar fabric of Productida is crossed by pseudopunctae with taleolae and the laminae are often organized in packages, with the blades oriented about perpendicular to each other; this feature is less evident in the laminar Or- thotetida, which bear pseudopunctae without taleoae. For the Rhynchonellata, fibrous fabrics are either impuctate in the Spiriferida, most Athyridida and Rhynchonellida, or with punctae, as observed in the Orthida, Terebratulida and in the Neoretziidae (Athyridida).

    1 PERMIAN AND TRIASSIC STRATIGRAPHY AND FOSSILS OF THE HIMALAYA IN NORTHERN NEPAL By J. B. WATERHOUSE Earthwise volume 6 2 ISBN 0-476-004180-7 Date of Publication March 31, 2004 Copyright J. B. Waterhouse Reproduction in full or in part, with acknowledgement, is authorized. Printed by Brackens, Oamaru 3 PREFACE This study focuses on Permian stratigraphy of the Manang district, north-central Nepal, and Carboniferous and Permian brachiopods significant from a regional Himalayan and world perspective. Fossiliferous Late Paleozoic rocks in the Manang district of north-central Nepal are exposed north of the Annapurna Range along the north side of the Marsyangdi valley from east of Braga settlement (11500ft, 3505m) to beyond Manang settlement (11650ft, 3551m), south of the peaks of Chulu (21672ft, 6630m and 20321ft, 6200m). The rocks persist westwards for 15km across Puchenpra Peak (16883ft, 4950m) and an unnamed peak at 17315ft, 5146m, along the north and west side of a huge glacial amphitheatre called Plateau of Lakes, and continue to Mesokanto Pass (16730ft, 5099m), then descend 5km along the Thini River valley to the Kali Gandaki River and the settlement of Jomson (8900ft, 2713m). Further west lies the region of Dolpo in northwest Nepal, where similar Permian-Triassic rocks are exposed north of the Dhaulagiri massif (Fuchs 1967, 1975, 1977, Waterhouse 1977, 1978). Overall these geological observations on Late Paleozoic and Early Mesozoic rocks and fossils extend over 160km, in a band 5-20km broad. General geological studies and maps of the Manang region by Bordet et al. (1975) and Fuchs et al. (1988) provide critical data on the regional setting, and Garzanti et al.

    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).

A list of brachiopods grouped according to R. E. King's localities and compiled from King's data by the authors is followed by the author's compilation of lists of brachiopods found at the localities designated by the United States Geological Survey, the American Museum of Natural History, Kansas University, and the National Museum of Natural History. The list pertaining to the last three groups of localities carries a code indicating the approximate number of speci­ mens of each taxon in the museum collections. A list of the authors' collection of ammonites is included, followed by lists of their fusulinids; these are ap­ pended to this monograph on brachiopods because they have important impli­ cations for dating and correlation.

Bapst <[email protected]> BugReports https://github.com/dwbapst/paleotree/issues Description Provides tools for transforming, a posteriori time-scaling, and modifying phylogenies containing extinct (i.e. fossil) lineages. In particular, most users are interested in the functions timePaleoPhy, bin_timePaleoPhy, cal3TimePaleoPhy and bin_cal3TimePaleoPhy, which date cladograms of fossil taxa using stratigraphic data. This package also contains a large number of likelihood functions for estimating sampling and diversification rates from different types of data available from the fossil record (e.g. range data, occurrence data, etc). paleotree users can also simulate diversification and sampling in the fossil record using the function simFossilRecord, which is a detailed simulator for branching birth-death-sampling processes composed of discrete taxonomic units arranged in ancestor-descendant relationships. Users can use simFossilRecord to simulate diversification in incompletely sampled fossil records, under various models of morphological differentiation (i.e. the various patterns by which morphotaxa originate from one another), and with time-dependent, longevity-dependent and/or diversity-dependent rates of diversification, extinction and sampling. Additional functions allow users to translate simulated ancestor-descendant data from simFossilRecord into standard time-scaled phylogenies or unscaled cladograms that reflect the relationships among taxon units.

Permian species are known from eleven fossil localities, and compare closely with Upper Permian Himalayan faunas from the Productus Shales, Chiticun 1, Kuling Shale, and Zewan beds of Kashmir, as well as the Upper Productus Limestone of the Salt *) New Zealand Geological Survey, Lower Hutt, New Zealand. ©Geol. Bundesanstalt, Wien; download unter www.geologie.ac.at 6 Range. The faunas are correlative with the Upper Permian Cyclolobus zone, generally presumed to come at the top of the Paleozoic succession, although possibly not as young as some Permian faunas of Japan and New Zealand. Two new genera are proposed, Multispinula with type species Strophalosia maxwelli WATBBHOUSB (1964 c), considered to include many species previously referred to Strophalosia, and Fusispirifer, with type species Spirifer nitiensis DIENER (1897 b). Newly named species are Ortho- tetes bisulcata, Anidanthus fusiformis, Costiferina alata, and Fusispirifer plicatus, and various other Upper Permian species are revised from exa­ mination of type material from the Salt Range and Himalaya, notably species of 'Strophalosia', Neospirifer moosakhailensis, N. ravana, Spiriferella rajah and S.
