ABsTRAcr-Shelf-derived limestone boulders in debris flows of the Cow Head Group, western Newfoundland, have yielded rich mid- to Upper Cambrian trilobite faunas.

GATEHOUSE 2 ABSTRACT Eight trilobite faunules ranging in age from Early Cambrian to late Middle Cambrian have been recovered from fossiliferous moraine boulders at Mount Spann in the northeastern Argentina Range, by:
Georg-August-Universitat, Gottingen, western Germany, and the trilobites from these have been presented to the Palaeontological Muse um in Oslo. The present study of the Lower and Middle Cambrian trilobites was initiated by the senior author (G.H.) in , but the work was inter rupted until when the junior author (F.N.). Middle Ordovician (late Dapingian–Darriwilian) conodonts from the Shallow Bay and Green Point formations, Cow Head Group, and the Lower Head Formation are recorded from three sections in Gros Morne National by: Trilobites of North America - the U.S. and Canada.

Along the upper reaches of this creek lay the scattered remains of hundreds of oddly preserved trilobites from the Upper Cambrian (Upper Steptoean, Ma). Unfortunately, further work was not carried out so the species are sort of in limbo. However, The Western Trilobite Association.
Lower Ordovician (Arenig) rocks of the Cow Head Group in western Newfoundland represent a well preserved fragment of the continental slope of the early Paleozoic Iapetus Ocean. Cow Head Group strata are characterized by conglomerate beds intercalated with deep water carbonates and minor siliciclastics. Three megaconglomerate units (b 12 and 14) on Cow Head Peninsula with Cited by: The Moroccan Atlas ranges provide sections which not only permit fine-scale biostratigraphic analysis of the basal part of the Middle Cambrian by means of typical West Gondwanan faunal elements, but also include exotic trilobites well known from other Cambrian continents or at least extremely rare in West Gondwana. Such trilobites often permit intercontinental correlation that Cited by: 5. Cambrian-Ordovician boundary sections in the Cow Head Group, western Newfoundland.
