Download or read book Conodonts from Ordovician Silurian Boundary Strata Whittaker Formation Mackenzie Mountains Northwest Territories written by Godfrey S. Nowlan and published by Geological Survey of Canada. This book was released on 1988 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: The taxonomic work provides detailed descriptions and illustrations of almost fifty species belonging to twenty-three genera. One new genus and five new species are erected. The resulting taxonomic framework is used to provide a correlation with strata of this age in other sedimentary basins in Canada and elsewhere.

Download or read book The Palynology and Micropalaeontology of Boundaries written by Alwynne Bowyer Beaudoin and published by Geological Society of London. This book was released on 2004 with total page 370 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume explores geological boundaries in time and space using palynology and micropalaeontology. Boundaries produce distinct signatures in the micropalaeontological record. They can tell us much about the response of biotic systems to environmental change in both marine and terrestrial realms. Different microfossil groups and geological contexts require their own approaches, definitions and considerations of boundaries. The papers here cover the methodology of boundary identification from biostratigraphical, ecological and palaeoenvironmental perspectives.

This book was released on 1991 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: This compilation is a synthesis of Ordovician-Triassic conodont research undertaken in the Canadian Cordillera during the past decade. The studies include an overview of the record in Western Canada; a review of the paleontology; and descriptions of conodonts from the Cordillera Road River group in northern Yukon Territory, from the eastern and northern Canadian cordillera, of the Palliser Formation in the Rocky Mountains, and from the Cache Creek Complex in south-central B.C.

Download or read book Protopanderodus Conodontata from the Ordovician Road River Group Northern Yukon Territory and the Evolution of the Genus written by Alexander D. McCracken and published by Energy Mines and Resources Canada. This book was released on 1989 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: Investigations of conodonts and other fossils from well exposed lower Paleozoic strata in the Cordillera of northern Yukon and western District of Mackenzie provide important information on the depositional and tectonic history of western Canada. This report presents the systematic description of 7 species of the Ordovician conodont genus Protopanderodus from carbonate beds within the predominately fine grained clastic rocks of the Road River Group. In addition, the spatial and temperal distribution of Protopanderodus was compiled to facilitate the interpretation of the paleoecology and evolution of this genus and its phylogenetic relationship with Drepanodus.

Book excerpt: Rare conodont-bearing carbonates, in contrast to common graptolitic shale demand that the systemic boundary in Yukon clastic facies be defined using graptolites.

Download or read book Upper Cambrian to Lower Ordovician Conodont Biostratigraphy and Biofacies Rabbitkettle Formation District of Mackenzie written by Ed Landing and published by University of Toronto Press. This book was released on 1980 with total page 664 pages. Available in PDF, EPUB and Kindle. Book excerpt: Conodonts have been recovered from two sections through the Cambrian-Ordovician boundary beds of the upper Rabbitkettle Formation, near the headwaters of the Broken Skull River, western Mackenzie Mountains. This report contributes towards a biofacies evaluation of Cambrian-Ordovician boundary bed conodonts and illustrates the probable limitations on a highly resolved conodont-based correlation of this interval between strongly constrasting lithofacies.
