Available in PDF, EPUB and Kindle. Book excerpt: The Gaptank Formation crops out in the vicinity of the North American standard Lower Permian in the Marathon Basin of Texas. The formation contains a rich, largely unstudied invertebrate fauna. The richest fossiliferous zone of the Gaptank Formation is Bed ten for which a Missourian age is indicated. The Pelecypoda fauna from Bed ten is diverse and includes nine new species. Some of these species are so unique that they do not compare well to any known species. For this reason and because internal characters could not be determined, open nomenclature is used in appropriate places. The Bed ten faunal assemblage seems to belong to what Johnson (1962) termed the Chonetina association, a normal marine assemblage. Further, the association of pelecypod with gastropod genera with an abundant calcareous brachiopod assemblage would seem to indicate a deep water environment; perhaps deeper than other described North American Pennsylvanian faunas. It is suggested that depth of water accounts for the uncommon diversity of the Bed ten pelecypods. Because species of the various systematic groups are normal in size and ornamentation and because many species are common Pennsylvanian forms, an isolated normal or restricted abnormal environment does not explain the unique morphological types and unique associations found in Bed ten.

Available in PDF, EPUB and Kindle. Book excerpt: The print edition is published as 2 hardback volumes, parts A and B, and sold as a set. The Carboniferous was the time of the assembly of Pangaea by the collision of the Gondwanan and Larussian supercontinents, and the principal interval of the late Paleozoic ice ages. These tectonic and climatic events caused dramatic sea-level fluctuations and climate changes and produced a Carboniferous world that was diverse topographically and climatologically, perhaps only rivalled in that diversity by the late Cenozoic world. Furthermore, the Carboniferous was a time of the accumulation of vast coal deposits of great economic and societal significance. The temporal ordering of geological and biotic events during Carboniferous time thus is critical to the interpretation of some unique and pivotal events in Earth history. This temporal ordering is based on the Carboniferous timescale, which has been developed and refined for nearly two centuries. This book reviews the history of the development of the Carboniferous chronostratigraphic scale and includes comprehensive analyses of Carboniferous radioisotopic ages, magnetostratigraphy, isotope-based correlations, cyclostratigraphy and timescale-relevant marine and non-marine biostratigraphy and biochronology.

Download or read book Foundations of Paleoecology written by S. Kathleen Lyons and published by University of Chicago Press. This book was released on 2019-12-13 with total page 787 pages. Available in PDF, EPUB and Kindle. Book excerpt: Approximately 99% of all life that has ever existed is extinct. Fortunately, these long dead species have left traces of their lives and interactions with other species in the rock record that paleoecologists use to understand how species and ecosystems have changed over time. This record of past life allows us to study the dynamic nature of the Earth and gives context to current and future ecological challenges. This book brings together forty-four classic papers published between 1924 and 1999 that trace the origins and development of paleoecology. The articles cross taxonomic groups, habitat types, geographic areas, and time and have made substantial contributions to our knowledge of the evolution of life. Encompassing the full breadth of paleoecology, the book is divided into six parts: community and ecosystem dynamics, community reconstruction, diversity dynamics, paleoenvironmental reconstruction, species interaction, and taphonomy. Each paper is also introduced by a contemporary expert who gives context and explains its importance to ongoing paleoecological research. A comprehensive introduction to the field, Foundations of Paleoecology will be an essential reference for new students and established paleoecologists alike.
