Stratigraphic Paleobiology


Book Description

This work weaves important strands of the paleontological literature into a coherent worldview that emphasizes the importance of understanding the geological record.




Stratigraphy and Paleontology of the Cloverly Formation (Lower Cretaceous) of the Bighorn Basin Area, Wyoming and Montana


Book Description

The fiftieth anniversary edition of a landmark publication showcasing prehistoric North American landscapes and ecosystems, from a celebrated paleontologist at Yale University's Peabody Museum The fiftieth anniversary edition of John H. Ostrom's Stratigraphy and Paleontology of the Cloverly Formation revisits his groundbreaking work pinpointing the age of the continental sequence of the Bighorn Basin area in Wyoming and Montana. The Cloverly Formation is important for understanding the development of North American terrestrial landscapes and prehistoric ecosystems, and current investigations are reinterpreting the age of the Formation with new evidence and data. The reissue of Ostrom's original benchmark research offers contemporary relevance for researchers and students today.







Seriation, Stratigraphy, and Index Fossils


Book Description

It is difficult for today's students of archaeology to imagine an era when chronometric dating methods were unavailable. However, even a casual perusal of the large body of literature that arose during the first half of the twentieth century reveals a battery of clever methods used to determine the relative ages of archaeological phenomena, often with considerable precision. Stratigraphic excavation is perhaps the best known of the various relative-dating methods used by prehistorians. Although there are several techniques of using artifacts from superposed strata to measure time, these are rarely if ever differentiated. Rather, common practice is to categorize them under the heading `stratigraphic excavation'. This text distinguishes among the several techniques and argues that stratigraphic excavation tends to result in discontinuous measures of time - a point little appreciated by modern archaeologists. Although not as well known as stratigraphic excavation, two other methods of relative dating have figured important in Americanist archaeology: seriation and the use of index fossils. The latter (like stratigraphic excavation) measures time discontinuously, while the former - in various guises - measures time continuously. Perhaps no other method used in archaeology is as misunderstood as seriation, and the authors provide detailed descriptions and examples of each of its three different techniques. Each method and technique of relative dating is placed in historical perspective, with particular focus on developments in North America, an approach that allows a more complete understanding of the methods described, both in terms of analytical technique and disciplinary history. This text will appeal to all archaeologists, from graduate students to seasoned professionals, who want to learn more about the backbone of archaeological dating.




Carbonate Sedimentology and Sequence Stratigraphy


Book Description

Sedimentology and stratigraphy are neighbors yet distinctly separate entities within the earth sciences. Sedimentology searches for the common traits of sedimentary rocks regardless of age as it reconstructs environments and processes of deposition and erosion from the sediment record. Stratigraphy, by contrast, concentrates on changes with time, on measuring time and correlating coeval events. Sequence stratigraphy straddles the boundary between the two fields. This book, dedicated to carbonate rocks, approaches sequence stratigraphy from its sedimentologic background. This book attempts to communicate by combining different specialities and different lines of reasoning, and by searching for principles underlying the bewildering diversity of carbonate rocks. It provides enough general background, in introductory chapters and appendices, to be easily digestible for sedimentologists and stratigraphers as well as earth scientists at large.




Ancient Oceans, Orogenic Uplifts, and Glacial Ice


Book Description

"This volume includes compelling science and field trips in Indiana, Illinois, Kentucky, Michigan, and Ohio. Take a journey through the Heartland to sand dunes, outcrops, quarries, rivers, caves, and springs that connect Paleozoic stratigraphy with the assembly of Gondwana, continental glaciation with Quaternary geomorphology and hydrology, and landscape with the human environment"--







STRATIGRAPHY, PALAEONTOLOGY AND PETROLOGY Geology


Book Description

Geology is an inter-discipliry science and the advance made in its understanding is based on valuable research contributed from the other sciences. This has given rise to a host of specialised fields such as environmental geology, marine geology, photogeology and mining geology, to me a few. This book has been written for the first year students of Geology and also for those who have opted for Geology as one of their subjects for competitive examitions such as UPSC, MPSC and others.

Coccolithophores


Book Description

Paleobiology is arguably the next frontier in micropaleontology, and no one group may have more impact on the global environment with a more enigmatic life history than the tiny coccolithophores, whose countless calcitic skeletons are a considerable percentage of oceanic biomass, with a major role in the Earth's carbon cycle. The isolated fragments or "coccoliths" that make up vast carbonate deposits are no longer to be considered as merely sedimentary particles but as the invaluable record of once living organisms that have an important story to tell in terms of evolutionary biology. It is in this perspective that Coccolithophores: Cenozoic Discoasterales-Biology, Taxonomy, Stratigraphy presents a century of research on a recently extinct group whose species consistently represented over half of the coccolithophore communities in low latitudes. Their distinctive morphologies and structures, described and abundantly illustrated in this volume, render them ideal for biological and phylogenetic reconstruction as well as tentative physiological interpretations. The application to biostratigraphy, biochronology and chronostratigraphy of the several hundred species in the order is also reviewed and complemented by an appendix (https://www.sepm.org/supplemental-materials) of four catalogues with genera and species organized according to comprehensive keys of determination. While the book is designed to inform biologists and earth scientists interested in plankton evolutionary history, the appendix will assist students and professionals alike in academia and industry with the taxonomy of the order and the dating of marine sedimentary successions in which they occur.
