Download or read book Toarcian (early Jurassic) Ammonoids from Western North America written by G. K. Jakobs and published by . This book was released on 1997 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: Toarcian (Early Jurassic) strata in the Queen Charlotte Islands have yielded a well-preserved and diverse ammonite fauna that provides a framework for a regional ammonite zonation for western North America described in this report. Other localities, particularly in southern Alaska and north- western British Columbia, have provided additional material contributing to the development of this zonation, which is of prime importance in determining the age of sedimentary strata and the relative timing of tectonic events. The report describes the biostratigraphy of the five western North American Toarcian ammonite zones, the occurrence and stratigraphy of Toarcian fossil occurrences in the western Cordillera, Pacific Northwest, and Queen Charlotte Islands, and biostratigraphic correlations with other areas including Europe. Systematic paleontological descriptions are provided of fossil ammonoids. The appendix includes fossil specimen locality data.

Book Synopsis Ammonoid Paleobiology by : Neil H. Landman
Download or read book Ammonoid Paleobiology written by Neil H. Landman and published by Springer Science & Business Media. This book was released on 2013-11-21 with total page 857 pages. Available in PDF, EPUB and Kindle. Book excerpt: Renowned researchers summarize the current knowledge on ammonoid paleobiology. The book begins with a description of the systematic position of the Ammonoidea within the Cephalopoda, providing the phylogenetic framework for the rest of the book. Following discussions include soft- and hard-part morphology of ammonoids, rate of growth and ontogeny, and taphonomy and ecology. Closing chapters explore the distribution of ammonoids in time and space as well as their extinction at the end of the Cretaceous. With its diverse viewpoints and new material, this resource will benefit researchers and graduate students in paleontology, marine biology, and evolutionary biology.

Book Synopsis Ammonoid Paleobiology: From macroevolution to paleogeography by : Christian Klug
Download or read book Ammonoid Paleobiology: From macroevolution to paleogeography written by Christian Klug and published by Springer. This book was released on 2015-07-22 with total page 615 pages. Available in PDF, EPUB and Kindle. Book excerpt: This two-volume work is a testament to the abiding interest and human fascination with ammonites. We offer a new model to explain the morphogenesis of septa and the shell, we explore their habitats by the content of stable isotopes in their shells, we discuss the origin and later evolution of this important clade, and we deliver hypotheses on its demise. The Ammonoidea produced a great number of species that can be used in biostratigraphy and possibly, this is the macrofossil group, which has been used the most for that purpose. Nevertheless, many aspects of their anatomy, mode of life, development or paleobiogeographic distribution are still poorly known. Themes treated are biostratigraphy, paleoecology, paleoenvironment, paleobiogeography, evolution, phylogeny, and ontogeny. Advances such as an explosion of new information about ammonites, new technologies such as isotopic analysis, tomography and virtual paleontology in general, as well as continuous discovery of new fossil finds have given us the opportunity to present a comprehensive and timely "state of the art" compilation. Moreover, it also points the way for future studies to further enhance our understanding of this endlessly fascinating group of organisms.

Book Synopsis Sedimentary Cover of the Craton in Canada by : D.F. Stott
Download or read book Sedimentary Cover of the Craton in Canada written by D.F. Stott and published by Geological Society of America. This book was released on 1993 with total page 713 pages. Available in PDF, EPUB and Kindle. Book excerpt: The early chapters of the volume present data and interpretations of the geophysics of the craton and summarise, with sequential maps, the tectonic evolution of the craton. The main body of the text and accompanying plates and figures present the stratigraphy, structural history, and economic geology of specific sedimentary basins and regions. The volume concludes with a summary chapter in which the currently popular theories of cratonal tectonics are discussed and the unresolved questions are identified.
