Download or read book Cambrian Ocean World written by John Foster and published by Indiana University Press. This book was released on 2014-06-06 with total page 457 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume, aimed at the general reader, presents life and times of the amazing animals that inhabited Earth more than 500 million years ago. The Cambrian Period was a critical time in Earth's history. During this immense span of time nearly every modern group of animals appeared. Although life had been around for more than 2 million millennia, Cambrian rocks preserve the record of the first appearance of complex animals with eyes, protective skeletons, antennae, and complex ecologies. Grazing, predation, and multi-tiered ecosystems with animals living in, on, or above the sea floor became common. The cascade of interaction led to an ever-increasing diversification of animal body types. By the end of the period, the ancestors of sponges, corals, jellyfish, worms, mollusks, brachiopods, arthropods, echinoderms, and vertebrates were all in place. The evidence of this Cambrian "explosion" is preserved in rocks all over the world, including North America, where the seemingly strange animals of the period are preserved in exquisite detail in deposits such as the Burgess Shale in British Columbia. Cambrian Ocean World tells the story of what is, for us, the most important period in our planet's long history.
Download or read book Earth System Evolution and Early Life written by A.T. Brasier and published by Geological Society of London. This book was released on 2017-06-09 with total page 429 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume in memory of Professor Martin Brasier, which has many of his unfinished works, summarizes recent progress in some of the hottest topics in palaeobiology including cellular preservation of early microbial life and early evolution of macroscopic animal life, encompassing the Ediacara biota. The papers focus on how to decipher evidence for early life, which requires exceptional preservation, employment of state-of-the-art techniques and also an understanding gleaned from Phanerozoic lagerstätte and modern analogues. The papers also apply Martin’s MOFAOTYOF principle (my oldest fossils are older than your oldest fossils), requiring an integrated approach to understanding fossils. The adoption of the null-hypothesis that all putative traces of life are abiotic until proven otherwise, and the consideration of putative fossils within their spatial context, characterized the work of Martin Brasier, as is well demonstrated by the papers in this volume.
Download or read book Understanding Fossils written by Peter Doyle and published by John Wiley & Sons. This book was released on 2014-08-15 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first introductory palaeontology text which demonstrates the importance of selected fossil groups in geological and biological studies, particularly in understanding evolutionary patterns, palaeoenvironmental analysis, and stratigraphy. Part one explores several key concepts, such as the processes of fossil preservation, the determination of evolutionary patterns, and use of fossils and statigraphical tools. Part two introduces the main fossil groups of value in these applied fields. Part three concentrates on the examination of important case histories which demonstrate the use of fossils in diverse practical examples. Evolutionary studies, palaeoenvironmental analysis, and stratigraphical applications are documented using up-to-date examples supported by overviews of the principles.
Download or read book Global Events and Event Stratigraphy in the Phanerozoic written by Otto H. Walliser and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 455 pages. Available in PDF, EPUB and Kindle. Book excerpt: The existence of rapid and even catastrophic turnovers within the Phanerozoic ecosystems has been discussed controversially for more than 170 years. Since 1980 this discussion has become even more intensive after the hypothesis of Alvarez, explaining the end-Cretaceous mass extinction as the result of a huge asteroid impact on the Earth. This theory stimulated several thousand papers and is still controversial. The international research programme on "Global Biological Events in Earth History" attempts to bring the discussion back to the facts by using multidisciplinary investigations of the major Phanerozoic events. The results of an international group of experts are presented giving a wealth of information and a thorough discussion of the causes of the various global events.
Download or read book The Paleobiological Revolution written by David Sepkoski and published by University of Chicago Press. This book was released on 2015-03-04 with total page 581 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Paleobiological Revolution chronicles the incredible ascendance of the once-maligned science of paleontology to the vanguard of a field. With the establishment of the modern synthesis in the 1940s and the pioneering work of George Gaylord Simpson, Ernst Mayr, and Theodosius Dobzhansky, as well as the subsequent efforts of Stephen Jay Gould, David Raup, and James Valentine, paleontology became embedded in biology and emerged as paleobiology, a first-rate discipline central to evolutionary studies. Pairing contributions from some of the leading actors of the transformation with overviews from historians and philosophers of science, the essays here capture the excitement of the seismic changes in the discipline. In so doing, David Sepkoski and Michael Ruse harness the energy of the past to call for further study of the conceptual development of modern paleobiology.

Download or read book Controversy Catastrophism and Evolution written by Trevor Palmer and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 463 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Controversy, Trevor Palmer fully documents how traditional gradualistic views of biological and geographic evolution are giving way to a catastrophism that credits cataclysmic events, such as meteorite impacts, for the rapid bursts and abrupt transitions observed in the fossil record. According to the catastrophists, new species do not evolve gradually; they proliferate following sudden mass extinctions. Placing this major change of perspective within the context of a range of ancient debates, Palmer discusses such topics as the history of the solar system, present-day extraterrestrial threats to earth, hominid evolution, and the fossil record.
Download or read book Interpretation of Biological and Environmental Changes Across the Neoproterozoic Cambrian Boundary written by L.E. Babcock and published by Gulf Professional Publishing. This book was released on 2005-11-30 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Neoproterozoic-Cambrian transition was a time of fundamental change in the biosphere. Between about 570 and 510 million years ago, marine organisms underwent considerable evolutionary innovation during a time of shifting ecological setting. This dramatic activity culminated in the first stratigraphic appearances of many recognizable groups of animals, an "event" often referred to as the "Cambrian explosion". In addition, there was a major change from a microbial mat-dominated sediment-water interface to a more extensively burrowed interface in shallow-marine settings. The early fossil record is a function not only of the rise or ecological diversification of marine organisms, but also the development of taphonomic and sedimentary conditions suitable for the preservation of mineralizing and nonmineralizing organisms. This book is devoted to an exploration of some of the emerging concepts and techniques used to develop greater insight into the early record of biologic diversification and the preservational record of that diversification during the Neoproterozoic-Cambrian transition. * Addresses key issues related to the Cambrian diversification of multicellular animals * Provocative new ideas about the factors involved in the exceptional preservation of fossils, with a balance between the development of ideas and hypothesis testing * Broad coverage of topics related to the Cambrian diversification of animals and the fossil record of that diversification; broad geographic coverage
Download or read book A Revised Correlation of the Cambrian Rocks in the British Isles written by A. W. A. Rushton and published by Geological Society of London. This book was released on 2011 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work reviews the correlation of the British and Irish Cambrian with the current (though incomplete) international standard for the Cambrian. Since the earlier edition of 1972, the basal and upper limits of the Cambrian system have been internationally agreed; so this account excludes Tremadocian rocks but includes some that were formerly considered Neoproterozoic. Half of the series and stage subdivisions are internationally agreed, but for the undefined divisions of the Cambrian the standard used here makes use of data from Avalonian successions. Since the first edition was published, almost every aspect of the Cambrian in the British Isles has been subjected to new study. Here, the plate tectonic make-up of the British Isles is reviewed, new radiometric ages and isotopic studies are summarized and the biostratigraphy is enhanced by the study of acritarchs, especially in the Irish successions.
