Braunberger W F; Hall R L.Canadian Journal of Earth Sciences, 2001,38(3): 333-346While the Cardium Formation (Turonian–Coniacian, Upper Cretaceous) is one of the majorhydrocarbon sources, and consequently oneof the most intensely studied siliciclastic formationsin the Western Canada Sedimentary Basin,it remains one of the more controversial units interms of understanding the depositional environmentsand processes it represents, and correlationsbetween subsurface and outcrop. Proposedsubsurface subdivisions based on sequencestratigraphic concepts, and relation ofthese allomembers to long-established membersof the outcrop belt, have provoked further disagreements.The general lack of biostratigraphicdata within the Cardium Formation makes it difficultto test different models and to resolve conflictingproposals. This paper provides stratigraphicand taxonomic information on all knownscaphitid ammonoids from the Cardium Formationand correlation of these faunas with the Turonianand Coniacian zonal scheme establishedin the United States Western Interior; future publicationswill provide similar treatments of thecollignoniceratid ammonites and inoceramidbivalves.2008040360加 拿 大 艾 伯 塔 上 白 垩 统 土 仑 阶 - 康 尼 亚 克 阶Cardium 组 和 相 邻 单 位 菊 石 动 物 群 :II.

Collignoniceratidaeand Placenticeratidae. ( 英 文 ).Braunberger W F; Hall R L. Canadian Journalof Earth Sciences, 2001, 38(7): 1117-1128Ammonite species of the genera Prionocyclus,Subprionocyclus, and Collignoniceras describedhere from the Cardium Formation, in combinationwith scaphitid ammonoids and inoceramidbivalves, allow recognition of all biozones forthe Turonian Stage (Upper Cretaceous) establishedfarther south in the United States WesternInterior Basin. Although many of the speciesused in this zonation were endemic to the WesternInterior seaway, more cosmopolitan forms atsome levels do allow correlation with westernEuropean sequences. The presence of Prionocyclusgermari Reuss is firmly established in thelower parts of the Leyland Member, confirmingthe position of the Turonian-Coniacian boundaryand earlier proposed constraints on the durationof the Cardinal–Leyland hiatus.2008040361北 美 下 侏 罗 统 菊 石 Amaltheidae 科 : 古 生 物地 理 和 大 地 构 造 意 义 = Lower JurassicAmaltheidae (Ammonitina) in North America:paleobiogeography and tectonic implications.( 英 文 ). Smith P L; Tipper H W; Ham D M. CanadianJournal of Earth Sciences, 2001, 38(10):1439-1449The amaltheids are restricted temporally to thelate Pliensbachian and geographically to thenorthern part of the northern hemisphere.Amaltheus stokesi is the only species that occursin all areas of North America where amaltheidsare found. The craton north of the Canada–U.S.A. border yields the most diverse amaltheidfauna, including six of the seven taxa known inNorth America. On Quesnellia and Stikinia,there are no endemic amaltheids, and diversity islow; A. stokesi increases in abundance northwardswhere, in Stikinia, A. margaritatus makesrare appearances. Wrangellia, with its richPliensbachian Tethyan and east Pacific faunas, isalmost devoid of amaltheids, but its amaltheidfauna does include two specimens of A. viligaensis,an eastern Russian species that is unknownelsewhere in North America. Cratonalamaltheid faunas have more in common withthose of northwest Europe than eastern Eurasia,suggesting that the Arctic and northern NorthAtlantic constituted the main dispersal route.Paleobiogeographic patterns on the major allochthonousterranes argue against terrane rotationand in support of post-Pliensbachian northwarddisplacement relative to the North Americancraton. In addition, the presence of western Pacificfaunal elements on Wrangellia suggests amore significant longitudinal displacement relativeto the craton for this terrane compared tothat for Quesnellia and Stikinia.2008040362加 拿 大 安 大 略 曼 尼 托 林 岛 对 晚 奥 陶 世 腹 足 类失 败 的 捕 食 = Failed predation in Late Ordoviciangastropods (Mollusca) from ManitoulinIsland, Ontario, Canada.
