Riccardi Institute of Sedimentary and Petroleum Geology Riccardi, A.C., An Upper Cretaceous ammonite and inoceramids from the Honna Formation, Queen Charlotte Islands, British Columbia; in Current Research, Part C, Paper S1-1C, p. 1-8, 1981. Abstract The lower part of the Honna Formation contains the Turonian bivalve species tiyliloides labiatus (Schlotheim) s.l., and Inoceramus sp. cf. L multiformis Pergament, whereas its uppermost beds have yielded the presumably Santonian ammonite Plesiotexanites? sp. indet. Therefore the formation appears to range from the early Turonian to the Santonian. The presence of Mytiloides labiatus s.l. in the upper pact of the underlying Haida Formation suggests the absence of a prolonged hiatus between the two formations and confirms their partial interfingering. Introduction The Honna and Skidegate formations of the Queen Charlotte Islands have yielded only a few generically and specifically indeterminate ammonite and inoceramid fragments to date. Therefore, they were assigned only a general Late Cretaceous (i.e. post-early Turonian) age by Sutherland Brown (1968, p. 98). The post-early Turonian age of the Honna Formation was indicated by the presence of the "Inoceramus" labiatus fauna in the immediately underlying Haida Formation (Sutherland Brown, 1968, p. 92). 13 1 10 ro Dixon Entrance \ 54 54 s O TJfn GRAHAM I ( QUEEN - ~*\ GWlnr} • <£^S wjiifskideqate GSC 100,976^^,*^^ O ^S?"

A new feature introduced in this edition is a section containing four essays: The HUDSON 70 Expedition by C.R. Mann Earth Sciences Studies in Arctic Marine Waters, 1970 by B.R. Pelletier Analysis of Marine Ecosystems by K.H. Mann Operation Oil by C.S. Mason and Wm. L. Ford They serve as an overview of the focal interests of the past two years in contrast to the body of the Review, which is basically a series of individual progress reports. The search for petroleum on the continental shelves of Eastern Canada and Arctic intensified considerably with several drilling rigs and many geophysical exploration teams in the field. To provide a regional depository for the mandatory core samples required from all drilling, the first stage of a core storage and archival laboratory was completed in 1970. This new addition to the Institute is operated by the Resource Administration Division of the Department of Energy, Mines & Resources. In a related move the Geological Survey of Canada undertook to establish at the Institute a new team whose primary function will be the stratigraphic mapping of the continental shelf.

Fieldwork conducted in Pontotoc County,Mississippi, targeted two sites containing montmorillonitic sand in the Maastrichtian Ripley Formation. U-Pb detrital zircon (DZ) ages from these sands (n = 649) ranged from Mesoarchean (~2870 Ma) to Pennsylvanian (~305 Ma) and contained ~91% Appalachian-derived grains, including Appalachian–Ouachita, Gondwanan Terranes, and Grenville source terranes. Other minor source regions include the Mid-Continent Granite–Rhyolite Province, Yavapai–Mazatzal, Trans-Hudson/Penokean, and Superior. This indicates that sediment sourced from the Appalachian Foreland Basin (with very minor input from a northern or northwestern source) was being routed through the Mississippi Embayment (MSE) in the Maastrichtian. We recognize six lithofacies in the field areas interpreted as barrier island to shelf environments. Statistically significant differences between DZ populations and clay mineralogy from both sites indicate that two distinct fluvial systems emptied into a shared back-barrier setting, which experienced volcanic ash input.

  • Circulation of Surface Waters in Parts of the Canadian Arctic Archipelago Based on Foraminiferal Evidence'
    Circulation of Surface Waters in Parts of the Canadian Arctic Archipelago Based on Foraminiferal Evidence' G. VILKS2 ABSTRACT. Planktonic foraminifera are present both in bottom sediments and surface waters on theshelf area averaging 400 metres in depth to the west of a line between Cape MClure and Cape Meecham, but in M'Clure Strait proper to the east of this line in the surface waters only. The evidence is used to suggest a slow net eastward movement of water from the ocean through MClure Strait in the past with increased ratesat the present time. RÉSUMÉ. La circulation des eaux de surface dans certaines parties de l'archipel arctique canadien, d'après l'étude des foraminifères. Dans la zone du plateau, d'une profondeur moyenne de 400 mètres, à l'Ouestd'une ligne tirée entre le cap de MClure et le cap de Meecham, les foraminifères planctoniques sont présents B la fois dans les sédiments du fond et dans les eaux de surface; mais à l'Est de cette ligne, dans le détroit de M'Clure proprement dit, on ne les trouve que dans les eaux de surface.

  • Phylogeny, Diversity, and Ecology of the Ammonoid Superfamily Acanthoceratoidea Through the Cenomanian and Turonian
    PHYLOGENY, DIVERSITY, AND ECOLOGY OF THE AMMONOID SUPERFAMILY ACANTHOCERATOIDEA THROUGH THE CENOMANIAN AND TURONIAN DAVID A.A. MERTZ A Thesis Submitted to the Graduate College of Bowling Green State University in partial fulfillment of the requirements for the degree of MASTER OF SCIENCE August 2017 Committee: Margaret Yacobucci, Advisor Andrew Gregory Keith Mann © 2017 David Mertz All Rights Reserved iii ABSTRACT Margaret Yacobucci Both increased extinction and decreased origination, caused by rising oceanic anoxia and decreased provincialism, respectively, have been proposed as the cause of the Cenomanian Turonian (C/T) extinction event for ammonoids. Conflicting evidence exists for whether diversity actually dropped across the C/T. This study used the ammonoid superfamily Acanthoceratoidea as a proxy for ammonoids as a whole, particularly focusing on genera found in the Western Interior Seaway (WIS) of North America, including Texas. Ultimately, this study set out to determine 1) whether standing diversity decreased across the C/T boundary in the WIS, 2) whether decreased speciation or increased extinction in ammonoids led to a drop in diversity in the C/T extinction event, 3) how ecology of acanthoceratoid genera changed in relation to the C/T extinction event, and 4) whether these ecological changes indicate rising anoxia as the cause of the extinction. In answering these questions, three phylogenetic analyses were run that recovered the families Acanthoceratidae, Collignoniceratidae, and Vascoceratidae. Pseudotissotiidae was not recovered at all, while Coilopoceratidae was recovered but reclassified as a subfamily of Vascoceratidae. Seven genera were reclassified into new families and one genus into a new subfamily. After calibrating the trees with stratigraphy, I was able to determine that standing diversity dropped modestly across the C/T boundary and the Early/Middle Turonian boundary.

  • From the Late Cretaceous (Campanian) Kanguk Formation of Axel Heiberg Island, Nunavut, Canada, and Its Ecological and Geographical Implications MATTHEW J
    ARCTIC VOL. 67, NO. 1 (MARCH 2014) P. 1 – 9 A Hadrosaurid (Dinosauria: Ornithischia) from the Late Cretaceous (Campanian) Kanguk Formation of Axel Heiberg Island, Nunavut, Canada, and Its Ecological and Geographical Implications MATTHEW J. VAVREK,1 LEN V. HILLS2 and PHILIP J. CURRIE3 (Received 1 October 2012; accepted in revised form 30 May 2013) ABSTRACT. A hadrosaurid vertebra was recovered during a palynological survey of the Upper Cretaceous Kanguk Formation in the eastern Canadian Arctic. This vertebra represents the farthest north record of any non-avian dinosaur to date. Although highly abraded, the fossil nonetheless represents an interesting biogeographic data point. During the Campanian, when this vertebra was deposited, the eastern Canadian Arctic was likely isolated both from western North America by the Western Interior Seaway and from more southern regions of eastern North America by the Hudson Seaway. This fossil suggests that large-bodied hadrosaurid dinosaurs may have inhabited a large polar insular landmass during the Late Cretaceous, where they would have lived year-round, unable to migrate to more southern regions during winters. It is possible that the resident herbivorous dinosaurs could have fed on non-deciduous conifers, as well as other woody twigs and stems, during the long, dark winter months when most deciduous plant species had lost their leaves. Key words: Appalachia, Arctic, Campanian, dinosaur, Laramidia, palaeobiogeography RÉSUMÉ. La vertèbre d’un hadrosauridé a été retrouvée pendant l’étude palynologique de la formation Kanguk remontant au Crétacé supérieur, dans l’est de l’Arctique canadien. Il s’agit de la vertèbre appartenant à un dinosaure non avien qui a été recueillie la plus au nord jusqu’à maintenant.
