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 has been published by NRC Research Press this book supported file pdf, txt, epub, kindle and other format this book has been release on 2002 with Conodonts categories.

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.

The Palynology And Micropalaeontology Of Boundaries written by Alwynne Bowyer Beaudoin and has been published by Geological Society of London this book supported file pdf, txt, epub, kindle and other format this book has been release on 2004 with Political Science categories.

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.

The Great Ordovician Biodiversification Event written by B. D. Webby and has been published by Columbia University Press this book supported file pdf, txt, epub, kindle and other format this book has been release on 2004 with Nature categories.

Two of the greatest evolutionary events in the history of life on Earth occurred during Early Paleozoic time. The first was the Cambrian explosion of skeletonized marine animals about 540 million years ago. The second was the "Great Ordovician Biodiversification Event," which is the focus of this book. This is the first book devoted specifically to establishing the global patterns of differentiation of Ordovician biotas through time and space. It provides extensive genus- and species-level diversity data for the many Ordovician fossil groups and presents an evaluation of how each group diversified, with assessments of patterns of change, and rates of origination and extinction.

"The Ordovician period is a significant chapter in Earth's history that included the great Mid-Ordovician biodiversification event, the Hirnantian glaciation, and long-term greenhouse conditions. Ordovician rocks are widespread on most continents and the recent finalization of a modern chronostratigraphic classification of the Ordovician system now facilitates high-resolution correlations that allow for integrated multidisciplinary research. The diverse papers comprising this volume address orogenesis, paleogeography, climate modeling, sedimentation, biodiversity, and isotopic excursions; together they promote an integrated view of the Ordovician earth system."--Publisher's description.
