Book Description
This study contains a documentation of conodont biofacies deduced from fragments of the shelf margin facies to establish a biostratigraphic zonation and to determine conodont paleoecology of the inner marginal environment through the Arenig interval. Among clasts in the megaconglomerates, local (lower slope derived), foreign (shelf, shelf break, and upper slope derived), and older clasts were distinguished. About 300 conodont samples were collected and processed, mainly from clasts of the three conglomerate horizons. The 12,492 conodont specimens recovered represent 132 different form and multi-element species.

Book Description
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.

Book Description
Darriwilian to Sandbian (Ordovician) Graptolites from Northwest China analyzes the significance of these exquisite, mostly pyritic, graptolites of the middle to late Ordovician period from North China and Tarim, China—locations that have developed the world's most complete successions of strata and fossil records. The book provides the first systematic account of the renowned graptolite faunas, with over 100 species belonging to 45 genera and 15 families preserved in black shale and limestone, also presenting a comprehensive accounting of the graptolites during the critical transition from the middle to late Ordovician period with important data on new morphologies, the latest conventions in classification, diversity change and evolution, refined biostratigraphy divisions, and correlation with other major regions or continents. The book provides a key resource for paleontologists, stratigraphic specialists, petroleum geologists, and graduate students in varying fields of geology. - Presents the first systematic accounting of these world-renowned graptolite fauna - Provides an ideal reference for those interested in rocks, fossils, and biostratigraphy - Presents over 100 species belonging to 45 genera and 15 families preserved in black shale and limestone - Includes research from the top, most influential, Ordovician graptolite and conodont paleontologists in the world - Generously illustrated with four-color figures and photos throughout

Book Description
This is the first book to investigate the structure, origin and evolution of carbonate mud-mounds. Mud-mounds are accumulations of biogenic carbonate sediment that are common in the geological record, and economically important as they host lead zinc mineralization and oil and gas. The book reviews, for the first time, the different mechanisms of mud-mound formation and examines in detail the major changes in mud-mound type and occurrence through geological time. The major part of the book contains case studies of mud-mounds from the Palaeozoic, Mesozoic and Cenozoic. The coverage is global and truly international, with 32 authors from 10 countries. The first volume to deal with the structure, formation and evolution of mud-mounds. Copiously illustrated, with nine colour plates.

Book Description
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. During the 46-million-year Ordovician Period (489–443 m.y.), a bewildering array of adaptive radiations of "Paleozoic- and Modern-type" biotas appeared in marine habitats, the first animals (arthropods) walked on land, and the first non-vascular bryophyte-like plants (based on their cryptospore record) colonized terrestrial areas with damp environments. This book represents a compilation by a large team of Ordovician specialists from around the world, who have enthusiastically cooperated to produce this first globally orientated, internationally sponsored IGCP (International Geological Correlation Program) project on Ordovician biotas. The major part is an assembly of genus- and species-level diversity data for the many Ordovician fossil groups. The book also presents an evaluation of how each group diversified through Ordovician time, with assessments of patterns of change and rates of origination and extinction. As such, it will become the standard work and data source for biotic studies on the Ordovician Period.

Book Description
The Glenogle Formation of British Columbia consists mainly of shale sections, and its graptolite faunas have been known for over a century but their stratigraphic setting has been uncertain. Recently discovered sections that are less contorted than most well-known localities allow elucidation of the formation's stratigraphy and of its succession of graptolite faunas. This report describes these newly discovered stratigraphic sections, outlines the stratigraphy & depositional environments of the Glenogle, puts forward a biostratigraphic synthesis of the graptolite faunas, and relates this zonation to North American zonations provided by conodonts & shelly fossils and to other graptolite sequences throughout the world.
