    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 New Early Visean Coral Assemblage from Azrou-Khenifra Basin, Central Morocco and Palaeobiogeographic Implications Sergio Rodríguez1,2* , Ian D
    Rodríguez et al. Journal of Palaeogeography (2020) 9:5 https://doi.org/10.1186/s42501-019-0051-5 Journal of Palaeogeography ORIGINAL ARTICLE Open Access A new early Visean coral assemblage from Azrou-Khenifra Basin, central Morocco and palaeobiogeographic implications Sergio Rodríguez1,2* , Ian D. Somerville3, Pedro Cózar2, Javier Sanz-López4, Ismael Coronado5, Felipe González6, Ismail Said1 and Mohamed El Houicha7 Abstract A new early Visean coral assemblage has been recorded from turbidite facies in the southern part of the Azrou- Khenifra Basin, northwest of Khenifra, central Morocco. The newly discovered Ba Moussa West (BMW) coral fauna includes Siphonophyllia khenifrense sp. nov., Sychnoelasma urbanowitschi, Cravenia lamellata, Cravenia tela, Cravenia rhytoides, Turnacipora megastoma and Pleurosiphonella crustosa. The early Visean age of the coral assemblage is supported by foraminiferal and conodont data, with the recognition of the basal Visean MFZ9 Zone. This confirms that the first transgression in the Azrou-Khenifra Basin was during the earliest Visean. The allochthonous coral assemblage was recovered from coarse-grained proximal limestone debris flow and turbidite beds within a fault- bounded unit, lying to the west of a thrust syncline containing upper Visean limestones. No evidence exists of the former early Visean shallow-water platform from which the corals were derived. All other in situ platform carbonate rocks around the southern margin of the Azrou-Khenifra Basin are probably of late Visean (Asbian–Brigantian) age. The early Visean Ba Moussa West coral fauna can be compared with that at Tafilalt in eastern Morocco, as well as in other Saharian basins of Algeria. Many of the genera and species in the Ba Moussa West assemblage are identical to those in NW Europe, with which it must have had marine connections.

  • The Wristen of the Permian Basin: Effect of Tectonics on Patterns In
    THE WRISTEN OF THE PERMIAN BASIN: EFFECT OF TECTONICS ON PATTERNS OF DEPOSITION, DIAGENESIS, AND RESERVOIR DEVELOPMENT IN THE LATE SILURIAN Stephen C. Ruppel Bureau of Economic Geology Jackson School of Geosciences The University of Texas at Austin Austin, Texas ABSTRACT Rocks of the Upper Silurian Wristen Group display a range in facies and depositional style that contrasts markedly with the more homogeneous character of the underlying Middle to Lower Silurian Fusselman Formation. The Wristen contains distinct (1) shallow-water platform (Fasken Formation) and (2) deeper water, outer platform to slope carbonate facies (Frame and Wink Formations) that document crustal downwarping of the southern margin of the Laurentian paleocontinent during the Middle Silurian. Deeper water facies of the Frame and Wink Formations dominate the more southerly areas of the Wristen subcrop in the Permian Basin and consist of nodular mudstones and wackestones (Wink) and carbonate debris flows and shales (Frame). Wristen platform facies are assigned to the Fasken Formation and include platform-margin carbonate buildup successions and a complex variety of middle to inner platform facies ranging from small carbonate buildup facies to skeletal wackestones and packstones to tidal-flat complexes. Hydrocarbon reservoirs are restricted to the Fasken Formation; more than 1.2 billion barrels of oil has been produced. A large volume of oil (more than 1.8 billion barrels) remains as a target for improved characterization of reservoir facies and architecture. The models and data presented here provide an important basis for better understanding of this complex depositional system. 1 INTRODUCTION The Silurian of the Permian Basin constitutes a thick section (as much as 2,000 ft) of carbonate platform, platform-margin, and slope rocks.

A detailed study of a fragment of a colony of tbe halysitid tabulate coral Catenipora heintzi from tbe Norwegian Wenlock is . presented. The specimen was collected from tbe Braksøya Formation near Nes, Ringerike. Closely spaced (O.l mm) senal sectlons . document astogenetical events and trends, including lateral and interstitial increase, branching, damage and regeneratlon, and lateral growth of individual corallites. Among tbese events, two previously undescribed phenom�na are observed: conn�tlon to � . neigbbouring rank as a result of interstitial increase, and competition between polyps leadmg to atroph�. The studted spectmen ts discussed in tbe light of tbe tbeories for halysitid astogeny. This indicates tbe existence of rank branching, tbe prefe�ence for increase from tbe youngest corallite in a rank, an exclusive ability of new corallites to fuse witb otber ranks,regulation of lacuna size, occasional sediment smotbering and possibly an annua! periodicity in frequency of increase.

  • 1 PATTERNS of MONTOYA GROUP DEPOSITION, DIAGENESIS, and RESERVOIR DEVELOPMENT in the PERMIAN BASIN Rebecca H. Jones ABSTRACT
    PATTERNS OF MONTOYA GROUP DEPOSITION, DIAGENESIS, AND RESERVOIR DEVELOPMENT IN THE PERMIAN BASIN Rebecca H. Jones ABSTRACT Rocks composing both the Montoya (Upper Ordovician) and Fusselman (Lower Silurian) Formations were deposited during the global climate transition from greenhouse conditions to unusually short-lived icehouse conditions on a broad, shallow-water platform. The Montoya and the Fusselman also share many reservoir characteristics and have historically been grouped together in terms of production and plays. Recently, however, the Montoya has garnered attention on its own, with new gas production in the Permian Basin and increased interest in global Ordovician climate. Recent outcrop work has yielded new lithologic and biostratigraphic constraints and an interpretation of four third-order Montoya sequences within Sloss’s second-order Tippecanoe I sequence. The Montoya Group comprises the Upham, Aleman, and Cutter Formations, from oldest to youngest. The Upham contains a basal, irregularly present sandstone member called the Cable Canyon. The boundary between the Montoya and the Fusselman is readily definable where a thin shale called the Sylvan is present but can be difficult to discern where the Sylvan is absent. Montoya rocks were deposited from the latest Chatfieldian to the end of the Richmondian stage of the late Mohawkian and Cincinnatian series (North American) of the Upper Ordovician. Montoya reservoir quality is generally better in the northern part of the Permian Basin where it is primarily dolomite compared to limestone Montoya reservoirs in the south. Reservoir quality is also better in the lower part of the unit compared to the upper, owing to a predominance of porous and permeable subtidal ooid grainstones and skeletal packstones in the former and peritidal facies in the latter.

They are Michelinia flugeli sp. nov., late Bashkirian, Michelinia sp. indet., late Bashkirian, Donetzites mariae Flügel, 1975, late Serpukhovian, Syringopora iranica sp. nov., late Serpukhovian, and Multithe- copora sp. cf.

The Sardar tabulate coral fauna occurs from limestones that formed in Peri-Gondwana at the low lati- tudes of the southern hemisphere and faced the Paleo-Tethys Ocean. Except for a cosmopolitan species, closely related to comparable species with the fauna are reported from the Akiyoshi seamount chain, the South China Continent, and the Australian eastern Gondwana.
