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.

This third volume in the IAS Reprint Series reviews some of themajor contributions that have been made over the last twenty yearsto our understanding of deep water environments. Few groups ofrocks have received as much attention in recent years as deep seasands and yet retained so many unsolved problems - How far and howfast can sediment debris flows travel? Do the many ancient seriesthat have been interpreted as submarine fan deposits bear anyresemblance to present day deep sea flows? How valid are thesequences described as coarsening upward or fining upward, and howshould they be interpreted? This timely review of contributionsmade to this area of study since 1970 reflects the heightenedinterest that has surrounded it. Deep Water Turbidite Systems contains 22 papers(reproduced in full) and 22 abstracts of papers that have appearedin the journal Sedimentology, concerned with the broadspectrum of topics within the field of turbidites and associateddeep water systems.

Selected papers from the August 1988 symposium on the Ordovician System. Authors from the U.K., Canada, Australia, and the U.S. contributed papers on a project to redefine regional chronostratigraphic subdivisions. Papers also cover Ordovician paleontology and biostratigraphy, emphasizing conodonts, graptolites and trilobites. The interrelationships of stratigraphy, eustasy, tectonics, and volcanisms are explored, with particular attention to the Appalachian Orogen. The final section of the volume documents some of the new data and interpretations of Ordovician paleo-oceanography, paleoclimatology, and paleogeography.
