Book Description
The book reviews and summarizes the Indian Mesozoic geological evolution in an innovative alternative perspective of sequence stratigraphy. It mainly focuses on the Jurassic interval, but also concisely discusses the preceding Triassic and Cretaceous geological records. The key to the study is primarily held in the recently developed ammonoid based high resolution scales in the Triassic and Jurassic period. The Indian Jurassic record is thus elevated to a high resolution pedestal. The large intra-Jurassic stratigraphic gap in Kachchh, with increase in duration from margin to basin, has been précised in different sections, along with radical revision of its long held interpretation from sub-aerial to sub-marine all over from Arabia to Australia. Other significant gaps are also differentiated into sub-aerial and sub-marine. The Indian Late Precambrian – Neogene record is organized into five mega-sequences. Among these, the fourth – also the most important one – includes the intra-Permian to Early Eocene interval from the origin to the closure of the Neotethys. Based on multidisciplinary integration of the Indian Mesozoic geological record and comparison with hydrocarbon producing basins on east and west of India, a highly positive scenario of the hydrocarbon source/reservoir sediment perspective is outlined in the book in sequence stratigraphic backdrop as an edifice for future elaborate evaluation.

Book Description
Most major recent advances in understanding the history of life on Earth have been through the study of exceptionally well preserved biotas (Fossil-Lagerstätten). These are windows on the history of life on Earth and can provide a fairly complete picture of the evolution of ecosystems through time. This book follows the success of Evolution of Fossil Ecosystems by the same authors which covered Fossil-Lagerstätten around the world. The success of the first book prompted this new book which draws on four localities from the original book and adds another ten, all located in North America. Following an introduction to Fossil-Lagerstätten, each chapter deals with a single fossil locality. Each chapter contains a brief introduction placing the Lagerstätte in an evolutionary context; there then follows a history of study of the locality; the background sedimentology, stratigraphy and palaeoenvironment; a description of the biota; discussion of the palaeoecology, and a comparison with other Lagerstätten of a similar age and/or environment. At the end of the book is an Appendix listing museums in which to see exhibitions of fossils from each locality and suggestions for visiting the sites.

Book Description
The biological effects of asteroid and comet impacts have been widely viewed as primarily destructive. The role of an impactor in the K/T boundary extinctions has had a particularly important influence on thinking concerning the role of impacts in ecological and biological changes. th During the 10 and final workshop of the ESF IMPACT program during March 2003, we sought to investigate the wider aspects of the involvement of impact events in biological processes, including the beneficial role of these events from the prebiotic through to the ecosystem level. The ESF IMPACT programme (1998-2003) was an interdisciplinary effort that is aimed at understanding impact processes and their effects on the Earth environment, including environmental, geological and biological changes. The IMPACT programme has 15 member states and the activities of the programme range from workshops to short courses on topics such as impact stratigraphy, shock metamorphism, etc. The program has also awarded mobility grants and been involved in the development of teaching aids and numerous publications, including this one.

Book Description
This study identifies the fall of dinosaurs as the factor that allowed mammals to evolve into the dominant tetrapod form. It refutes the single-cause impact theory for dinosaur extinction and demonstrates that multiple factors--massive volcanic eruptions, loss of shallow seas, and extraterrestrial impact--likely led to their demise. While their avian relatives ultimately survived and thrived, terrestrial dinosaurs did not. Taking their place as the dominant land and sea tetrapods were mammals, whose radiation was explosive following nonavian dinosaur extinction. The author argues that because of dinosaurs, Mesozoic mammals changed relatively slowly for 145 million years compared to the prodigious Cenozoic radiation that followed. Finally out from under the shadow of the giant reptiles, Cenozoic mammals evolved into the forms we recognize today in a mere ten million years after dinosaur extinction.

Book Description
Terrestrial Depositional Systems: Deciphering Complexities through Multiple Stratigraphic Methods is the first collection of contributed articles that not only introduces young geoscientists to biostratigraphy, chemostratigraphy, magnetostratigraphy, and lithostratigraphy, but also provides seasoned practitioners with a standard reference that showcases the topic's most recent developments in research and application. When studying complex depositional systems, scientists often need to rely on more than one stratigraphic technique to truly understand the sequence of historical events. Through a blend of specific analytical techniques, experiments, sampling methods, and working examples, this book provides a practical reference for addressing a range of depositional system challenges. This multi-contributed reference combines reviews of stratigraphic methods with individual case studies, providing readers with a broad scope of techniques that will aid their work in the interpretation and understanding of complex depositional systems. - Offers multi-contributed expertise in biostratigraphy, chemostratigraphy, magnetostratigraphy, and lithostratigraphy, ensuring a thorough, yet topical coverage - Features case studies in each chapter that underscore the range of applications of individual stratigraphic methods - Provides detailed explanations of different analyses, data collection methods, and sampling techniques, making the content immediately implementable - Includes more than 100 illustrations, figures, and photographs that provide visual representations of core concepts
