This book was released on 1983 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The results of this study allow more precise correlations to be made with the classic Lower Silurian rocks of the Welsh Borderland in Great Britain, and will also facilitate making closer correlations between strata of this age in other sedimentary basins in Canada and elsewhere. Accurate dating of rocks is of great importance in assessing the hydrocarbon and other mineral potential of sedimentary basins." --

Download or read book Taxonomy Evolution and Biostratigraphy of Conodonts from the Kechika Formation Skoki Formation and Road River Group Upper Cambrian to Lower Silurian Northeastern British Columbia written by Leanne J. Pyle and published by NRC Research Press. This book was released on 2002 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: Conodonts, the tiny, phosphatic, tooth-like remains of an extinct group of early vertebrates, are the most important fossil group for biostratigraphy throughout their stratigraphic range from Late Cambrian to Late Triassic. This monograph represents a benchmark study of these important zonal fossils. The detailed paleontological work not only provides a taxonomic basis for future studies on early Paleozoic conodonts but also focuses on the evolution of conodonts in the early Ordovician, a time of extraordinary adaptive radiation. The taxonomic work provides detailed descriptions and illustrations of 185 species representing 69 genera. Seven new genera and 39 new species are described. The high diversity of taxa across the platform-to-basin transect shows the biogeographic differentiation and spatial ecological partitioning of conodonts through time. The taxonomy permits the refinement to the biostratigraphic zonation within two faunal realms for British Columbia that can be correlated with schemes elsewhere in North America and also internationally.

Thorsteinsson and published by Geological Survey of Canada. This book was released on 1980 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Boothia Uplift is a major structural feature that extends north from Boothia Peninsula to the northwestern extremity of Devon Island. On Somerset Island and Boothia Peninsula it consists of Precambrian crystalline rocks and Proterozoic sediments that are flanked by Cambrian to Lower Devonian platform-type sedimentary rocks. This report deals with strata of Late Silurian to Early Devonian age, the time of the principal crustal movements that produced the Uplift." --
Download or read book A New Silurian Llandovery Telychian Sponge Assemblage from Gotland Sweden written by Freek Rhebergen and published by John Wiley & Sons. This book was released on 2014-02-20 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: A newly discovered, diverse sponge fauna of early Silurian age, is described from Gotland, Sweden. This is the first Silurian sponge assemblage known from Baltica, and the only diverse Llandoverian assemblage known worldwide. The fauna includes 20 genera and 29 species, of which three genera and six species are new. Eighteen species are new to Baltica. The fauna shows strong similarities to later Silurian assemblages in Arctic Canada, but one endemic species comprises ca. 50% of the fauna. The fauna shows that lithistid sponges recovered well from the late Ordovician extinction in some areas, and became widely spread in the early Silurian. In contrast, non-lithistid sponges like, such as hexactinellids, appear to have evolved rapidly during the Late Ordovician – early Silurian interval, and some modern groups probably originated in inshore habitats.
