Book excerpt: Fossils and Strata is an international series of monographs and memoirs in palaeontology and biostratigraphy, owned by, and published on behalf of, The Lethaia Foundation in cooperation between the Scandinavian countries. Fossils and Strata forms part of the same structured publishing programme as the international journal Lethaia and provides a complementary outlet for more comprehensive systematic and regional monographs, including taxonomic descriptions. Fossils and Strata also offers the publication of thematic special issues comprising a series of shorter contributions.
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.

Download or read book The Triassic Timescale written by Spencer G. Lucas and published by Geological Society of London. This book was released on 2010 with total page 528 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Mesozoic Era begins with the approximately 50-million-year-long Triassic Period, a major juncture in Earth history when the vast Pangaean supercontinent completed its assembly and began its fragmentation, and the global biota diversified and modern-ized after the end-Permian mass extinction, the most extensive biotic decimation of the Phanerozoic. The temporal ordering of geological and biotic events during Triassic time thus is critical to the interpretation of some unique and pivotal events in Earth his-tory. This temporal ordering is mostly based on the Triassic time-scale, which has been developed and refined for nearly two centu-ries. This book reviews the state of the art of the Triassic timescale and includes comprehensive analyses of Triassic radio-isotopic ages, magnetostratigraphy, isotope-based and cyclostratigraphic correlations and timescale -relevant marine and non-marine bio-stratigraphy.
