Understanding Late Devonian and Permian-Triassic Biotic and Climatic Events
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.* Provides updated, current models for the mid-Late Devonian and Permian-Triassic mass extinction episodes* Highlights several new analytical approaches for developing quantitative datasets* Takes an integrated approach presenting datasets from a broad range of sub-disciplines
Ichnology of the Permian-Triassic Mass Extinction in China
This book provides a detailed examination of ichnology during the Permian-Triassic mass extinction in China, focusing on the recovery patterns of marine trace-making organisms. It features a wealth of high-quality ichnofossil photographs and figures, offering readers a comprehensive guide to ichnotaxa identifications and descriptions from both South and North China, spanning the Late Permian to the Middle Triassic. The chapters cover critical topics such as the delayed biotic recovery due to the harsh environmental conditions of the Early Triassic oceans. Ichnological data is highlighted as a crucial tool for assessing the recovery process and patterns of marine trace-making organisms. The book includes ecological and sedimentological data, providing insights into the recovery patterns of marine infaunas across various habitats. It systematically presents semi-quantitative parameters of several ecological proxies, proposing different recovery models based on extensive data. Written by authorities in the field, this book is an invaluable reference for ecological and ichnological researchers. It is designed for undergraduates and graduate students in earth sciences, as well as researchers and professionals interested in ichnology and marine recovery post-extinction. This publication is an essential resource for understanding the intricate dynamics of marine ecosystems during one of Earth's most significant biocrises. It is a crucial addition to the field, offering a unique perspective on the recovery patterns of marine trace-making organisms in the aftermath of the end-Permian mass extinction.
Devonian Climate, Sea Level and Evolutionary Events

The geological and palaeontological records of climate change and evolutionary events reflect Earth’s widely fluctuating climate systems. Past climates hold the clues to understanding future developments. In this context, research on linked climate, biodiversity and sea-level fluctuations of the Devonian contributes to the general knowledge of deep-time climate dynamics. A fruitful co-operation between the International Geoscience Programme IGCP 596 and the International Subcommission on Devonian Stratigraphy (SDS) addressed the complex succession of climate-linked Devonian global events of varying magnitude. The primary goal of IGCP 596 was to assess mid-Palaeozoic climate changes and their impact on marine and terrestrial biodiversity using an interdisciplinary approach. The focus of SDS includes a revision of the eustatic sea-level curve and the integration of refined chrono- and biostratigraphy with modern chemo-, magneto-, cyclo-, event- and sequence stratigraphy. This enabled the much improved dating and correlation of abiotic perturbations, evolutionary changes, organism and ecosystem ranges. Results by 37 authors are presented in 14 chapters, which cover the entire Devonian.
