Understanding Late Devonian and Permian-Triassic Biotic and Climatic Events

About this book

The Late Devonian and Permian-Triassic intervals are among the most dynamic episodes of Earth history, marked by large secular changes in continental ecosystems, dramatic fluctuations in ocean oxygenation, major phases of biotic turnover, volcanism, bolide impact events, and rapid fluctuations in stable isotope systems and sea level. This volume highlights contributions from a broad range of geological sub-disciplines currently striving to understand these critical intervals of geologically rapid, global-scale changes.

Contents

1. Preface/Introduction to Volume. 2. Toward understanding Late Devonian global events: few answers, many questions. 3. Modelling Late Devonian extinction hypotheses. 4. Sedimentary Fill of the Late Devonian Flynn Creek Crater: A Hard Target Marine Impact. 5.

Using environmental niche modelling to study the Late Devonian biodiversity crisis. 7. Subdivision of the terminal Frasnian linguiformis conodont Zone, revision of the correlative interval of Montagne Noire Zone 13, and discussion of stratigraphically significant associated trilobites. 8. Productivity and bottom water redox conditions at the Frasnian-Fammennian boundary on both sides of the Eovariscan Belt: constraints from trace-element geochemistry. 9. Evidence for Late Devonian (Kellwasser) anoxic events in the Great Basin, western United States. 10. Late Permian double-phased mass extinction and volcanism: an oceanographic perspective. 11.
