Here twenty-one leading paleontologists use important refinements in fossil diversity data to provide critical evaluations of older hypotheses of diversification and extinction processes and to propose fresh interpretations. Originally published in 1986. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

"This detailed study of silicified Ostracoda from part of the Esbataottine Formation provides a basis for correlation of circum-cratonal early Middle Ordovician rocks of North America and consideration of their conditions of deposition." --

The early chapters of the volume present data and interpretations of the geophysics of the craton and summarise, with sequential maps, the tectonic evolution of the craton. The main body of the text and accompanying plates and figures present the stratigraphy, structural history, and economic geology of specific sedimentary basins and regions. The volume concludes with a summary chapter in which the currently popular theories of cratonal tectonics are discussed and the unresolved questions are identified.

Two measured sections of the upper Rabbitkettle Formation in the western District of Mackenzie are separated by a thrust fault. These sections provide a record of silicified tribobite faunas across the Cambrian-Ordovician boundary in open marine carbonate rocks along the deeper portion of the shelf - a North American palaeogeographic setting not previously extensively sampled for macrofossils.

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.
