Brachiopods Around The Permian Triassic Boundary Of South China

This timely book documents marvelous brachiopod fossils from the Palaeozoic-Mesozoic transition of South China. Numerous beautiful pictures and detailed descriptions (specifically the measurements of body size) of brachiopod species are presented. Systematic discussion on the evolution of brachiopod biodiversity and morphological features across the critical interval is not only extremely important for paleontologists to understand the marine ecosystem evolution from the Palaeozoic to the Mesozoic, but also attractive for students who need to know about the end-Permian mass extinction. The book distinguishes itself from other studies by its detailed study of the taxonomy, biodiversity and paleoecology of Permian-Triassic brachiopods from different palaeogeographic facies, especially from the deep-water environment in South China. The book also offers a unique study of the response of morphological features of brachiopods to palaeoenvironmental changes, providing insights for the process of Permian-Triassic crisis.

ovaloides, Squamularia formilla, Hustedia orbicostata, Rostranteris ptychiventria, and Notothyris bifoldes).The Cathaysia chonetoides-Chonetinella substrophomenoides assemblage zone and the Cathaysia sinuata-Waagenites barusiensis assemblage zone represent respectively faunas of the lower Changxingian and the upper Changxingian in clastic lithofacies; whereas the Peltichia zigzag-Prelissorhynchia triplicatioid assemblage zone and the Spirigerella discusella-Acosarina minuta assemblage zone represent faunas in limestone lithofacies.

This book timely provides high-quality records of 32 PTB sections across different depositional settings from terrestrial to marine facies in South China, including descriptions of lithologies, high-resolution correlation of key boundaries and fossil occurrences at each section. This book also analyzes the patterns and processes of the community and ecosystem evolution over space and through time in the lead to the end-Permian mass extinction, and critically analyzes the mostly debated hypothesis, anoxia and volcanism, which were considered as the causes of mass extinction, based on the data from the studied sections of South China, together with materials from other regions of the world.

This book documents timely and systematically marvelous fossils (plants and sporopollen) related to the biggest mass extinction of the Permian–Triassic transition. Numerous beautiful pictures and comprehensive records on the plants of this unique and critical interval of geohistory are presented in this book. It greatly contributes to understanding of the Permian–Triassic plant diversity and evolution. For geologists, it is important to understand the Permian–Triassic crisis, and for students, it is attractive to learn about the plants’ response to palaeoclimatic changes.

The first book to review all the evidence concerning both the dinosaur extinctions and all the other major extinctions - of plant, animal, terrestrial, and marine life - in the history of life. All the extinction mechanisms are critically assessed, including meteorite impact, anoxia, and volcanism. - ;Why do mass extinctions occur? The demise of the dinosaurs has been discussed exhaustively, but has never been out into the context of other extinction events. This is the first systematic review of the mass extinctions of all organisms, plant and animal, terrestrial and marine, that have occurred in the history of life. This includes the major crisis 250 million years ago which nearly wiped out all life on Earth. By examining current paleontological, geological, and sedimentological evidence of environmental changes, the cases for explanations based on climate change, marine regressions, asteroid or comet impact, anoxia, and volcanic eruptions are all critically evaluated. -

This collection of conference papers presents information on the molecular genetics, biomineralization, growth and ecology of extant brachiopod stocks (extrapolated back to the Cambrian), and the shell microstructure, taphonomy, paleogeography, evolution, and taxonomy of fossil brachiopods.

This volume focuses on the broad pattern of increasing biodiversity through time, and recurrent events of minor and major ecosphere reorganization. Intense scrutiny is devoted to the pattern of physical (including isotopic), sedimentary and biotic circumstances through the time intervals during which life crises occurred. These events affected terrestrial, lacustrine and estuarine ecosystems, locally and globally, but have affected continental shelf ecosystems and even deep ocean ecosystems. The pattern of these events is the backdrop against which modelling the pattern of future environmental change needs to be evaluated.

This volume brings together state-of-the-art reviews of the non-biostratigraphic and biostratigraphic data that are used to define and correlate Permian time intervals. It includes analyses of Permian radio-isotopic ages, magnetostratigraphy, isotope-based stratigraphy and timescale-relevant biostratigraphy. It is the first book devoted to this subject and represents the cutting edge of Permian time-scale research.
