Late Ordovician And Early Silurian Pentamerid Brachiopods From Anticosti Island Qu Bec Canada

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.

It has become apparent from the literature that bioerosional processes affect a wide range of biological and geological systems that cross many disciplines among the sciences. This book is dedicated to crossing those traditional disciplinary boundaries to present a united and current perspective on the pattern and process of bioerosion. The book opens with papers on the evolutionary significance of bioerosion. It concludes with a primer on the bioerosion bibliography website.

Because of their generally great abundance and high diversity, brachiopods from the Red River and Stony Mountain formations of southern Manitoba are important to understanding the pattern, process, and rate of evolution, radiation, and extinction of the North American epicontinental marine shelly benthos during the Late Ordovician. This report presents a detailed taxonomic treatment of these brachiopods, coupled with an assessment of their implications for biostratigraphy, palaeoecology, and palaeobiogeography at continental and global scales.

The growth history of a brachiopod is entombed in its shell, but research on fossil and living brachiopods has generated unanswered questions about these marine invertebrates. Several contributors to Brachiopods Past and Present comment on their differing structures and morphological detail. They use these as examples of ontogenetic and evolutionar
