Introduction -- Common Trace-Making Endobenthic Invertebrates -- Descriptive Ichnology -- Biophysical Mechanisms of Crab Burrowing -- Ichnozones and their Characterization -- Preservation of Traces -- Ichnofacies and Ichnofabrics -- Spatio-Temporal Changes in Ichnozones -- Geological Significance -- Summary and Conclusions.This book focuses on the world’s largest mangrove delta complex, located at Sundarban, a world heritage site, and on the relatively new and rapidly expanding scientific discipline of ichnology. In addition to presenting a range of ichnological research databases that are widely applicable to multidisciplinary research fields in geology, biophysics, biology, ecology, geomorphology and the marine and environmental sciences, it addresses the global concern of rising sea levels to explain growing ecological problems, from the mass mortality of coastal organisms and rapid loss of mangrove forest wealth, to widespread coastal and riverbank erosion. It also demonstrates the value of applying new ichnological tools to coastal geotechnical planning and programming, and to groundwater exploration. Thus, the book addresses a broad readership including earth scientists from various disciplines, state administrators and members of the general public.
