Download or read book Ostracoda from the Ellis Bay Formation Ordovician Anticosti Island Quebec written by Murray John Copeland and published by . This book was released on 1973 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 200- to 300- foot-thick Ellis Bay Formation on Anticosti Island has yielded a well preserved and distinctive ostracode fauna. This fauna is closely related to that of the underlying Vaureal Formation and contains elements common to the Porkuni beds of Estonia and the Dalmanitina Series (5a, 5b) of Norway. The Late Ordovician age of these faunas is indicted.
Download or read book Late Ordovician Orthide and Billingsellide Brachiopods from Anticosti Island Eastern Canada written by Jisuo Jin and published by NRC Research Press. This book was released on 2008 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: A monographic study that deals with a major marine faunal turnover during the Late Ordovician global greenhouse/icehouse episodes. It aims to document the diversity change of brachiopods (one of the major groups of marine life during the Ordovician Period) from pre-extinction to extinction times.
Download or read book Ordovician Faunas Trilobita Ostracoda Cystoidea Crinoidea from West Thailand written by Reinhard Wolfart and published by . This book was released on 2001 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume describes Ordovician faunas from West Thailand (Khanchanaburi, Tong Pha Phum, and Bo Noi regions), their meaning for biostratigraphy and palaeogeography (some notes on climate, ecology, and sedimentation) in the Burmese-Malayan geosyncline. It includes also worldwide important palaeontological reference works. This paper concerns palaeontologists, stratigraphers, sedimentologists, and structural geologists interested in this long and ancient period of Earth history.

Download or read book Mass Extinctions and Their Aftermath written by A. Hallam and published by OUP Oxford. This book was released on 1997-09-11 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: Why do mass extinctions occur? The demise of the dinosaurs has been discussed exhaustively, but has never been out into the context of other extinction events. This is the first systematic review of the mass extinctions of all organisms, plant and animal, terrestrial and marine, that have occurred in the history of life. This includes the major crisis 250 million years ago which nearly wiped out all life on Earth. By examining current paleontological, geological, and sedimentological evidence of environmental changes, the cases for explanations based on climate change, marine regressions, asteroid or comet impact, anoxia, and volcanic eruptions are all critically evaluated.

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 Introduction to Microfossil Biostratigraphy written by M. Dan Georgescu and published by Cambridge Scholars Publishing. This book was released on 2021-09-24 with total page 285 pages. Available in PDF, EPUB and Kindle. Book excerpt: This textbook will appeal to students and graduates making their first steps in the application of both microfossils and stratigraphy. It presents, in detail, the historical development of microfossil biostratigraphy, from its birth to the emergence of sequence stratigraphy, including its roots in classical biostratigraphy. The interplay between the academic and economical challenges, on one hand, and developments in microfossil biostratigraphy, on the other, is explored thoroughly. The book also presents an introduction to the scientific concepts used in microfossil biostratigraphy practice, and the uses in microbiostratigraphy of 25 groups of microfossils, such as algae, protistans, reproductive plant debris, invertebrates, chordates and vertebrates, and microproblematica groups. It also provides a numerical method to calculate the biostratigraphical resolution of these microfossil groups.
