This book was released on 2023-06-06 with total page 329 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ichnology of shallow-marine to transitional environments is a key field of study with respect to understanding the variability of environmental parameters from inshore marginal-marine settings to the offshore transition zone. Over the last decades ichnology has evolved from being a tool to determine bathymetry, becoming the standard palaeoenvironmental methodology by which trace fossils can be used to inform sedimentary facies models. In particular, the analysis of mixed assemblages of invertebrate and vertebrate trace fossils allows detailed palaeoenvironmental and facies analysis. This volume focuses on the ichnological record of shallow-marine to transitional environments through the geological record, in addition to modern ones through neoichnology.

Available in PDF, EPUB and Kindle. Book excerpt: Roland Thaxter Bird, universally and affectionately known to friends and associates as R. T., achieved a kind of Horatio Alger success in the scientific world of dinosaur studies. Forced to drop out of school at a young age by ill health, he was a cowboy who traveled from job to job by motorcycle until he met Barnum Brown, Curator of Vertebrae Paleontology at the American Museum of Natural History in New York and a leader in the study of dinosaurs. Beginning in 1934, Bird spent many years as an employee of the museum and as Brown's right-hand man in the field. His chart of the Howe Quarry in Wyoming, a massive sauropod boneyard, is one of the most complex paleontological charts ever produced and a work of art in its own right. His crowning achievement was the discovery, collection, and interpretation of gigantic Cretaceous dinosaur trackways along the Paluxy River near Glen Rose and at Bandera, Texas. A trackway from Glen Rose is on exhibit at the American Museum and at the Texas Memorial Museum in Austin. His interpretation of these trackways demonstrated that a large carnosaur had pursued and attacked a sauropod, that sauropods migrated in herds, and that, contrary to then-current belief, sauropods were able to support their own weight out of deep water. These behavioral interpretations anticipated later dinosaur studies by at least two decades. From his first meeting with Barnum Brown to his discoveries at Glen Rose and Bandera, this very human account tells the story of Bird's remarkable work on dinosaurs. In a vibrantly descriptive style, Bird recorded both the intensity and excitement of field work and the careful and painstaking detail of laboratory reconstruction. His memoir presents a vivid picture of camp life with Brown and the inner workings of the famous American Museum of Natural History, and it offers a new and humanizing account of Brown himself, one of the giants of his field. Bird's memoir has been supplemented with a clear and concise introduction to the field of dinosaur study and with generous illustrations which delineate the various types of dinosaurs.

Available in PDF, EPUB and Kindle. Book excerpt: This look at the field of ichnology is “an excellent compendium and a timely piece on a rapidly expanding and changing area of research” (Quarterly Review of Biology). The latest advances in dinosaur ichnology are showcased in this comprehensive and timely volume, in which leading researchers and research groups cover the most essential topics in the study of dinosaur tracks. Some assess and demonstrate state-of-the-art approaches and techniques, such as experimental ichnology, photogrammetry, biplanar X-rays, and a numerical scale for quantifying the quality of track preservation. The high diversity of these up-to-date studies underlines that dinosaur ichnological research is a vibrant field, that important discoveries are continuously made, and that new methods are being developed, applied, and refined. This indispensable volume unequivocally demonstrates that ichnology has an important contribution to make toward a better understanding of dinosaur paleobiology. Tracks and trackways are one of the best sources of evidence to understand and reconstruct the daily life of dinosaurs. They are windows on past lives, dynamic structures produced by living, breathing, moving animals now long extinct, and they are every bit as exciting and captivating as the skeletons of their makers. Includes photos and illustrations
Download or read book Noah s Ravens written by James O. Farlow and published by Indiana University Press. This book was released on 2018-10-08 with total page 656 pages. Available in PDF, EPUB and Kindle. Book excerpt: How can the tracks of dinosaurs best be interpreted and used to reconstruct them? In many Mesozoic sedimentary rock formations, fossilized footprints of bipedal, three-toed (tridactyl) dinosaurs are preserved in huge numbers, often with few or no skeletons. Such tracks sometimes provide the only clues to the former presence of dinosaurs, but their interpretation can be challenging: How different in size and shape can footprints be and yet have been made by the same kind of dinosaur? How similar can they be and yet have been made by different kinds of dinosaurs? To what extent can tridactyl dinosaur footprints serve as proxies for the biodiversity of their makers? Profusely illustrated and meticulously researched, Noah's Ravens quantitatively explores a variety of approaches to interpreting the tracks, carefully examining within-species and across-species variability in foot and footprint shape in nonavian dinosaurs and their close living relatives. The results help decipher one of the world's most important assemblages of fossil dinosaur tracks, found in sedimentary rocks deposited in ancient rift valleys of eastern North America. Those often beautifully preserved tracks were among the first studied by paleontologists, and they were initially interpreted as having been made by big birds—one of which was jokingly identified as Noah's legendary raven.

Download or read book Terrestrial Ecosystems Through Time written by Anna K. Behrensmeyer and published by University of Chicago Press. This book was released on 1992-08-15 with total page 588 pages. Available in PDF, EPUB and Kindle. Book excerpt: Breathtaking in scope, this is the first survey of the entire ecological history of life on land—from the earliest traces of terrestrial organisms over 400 million years ago to the beginning of human agriculture. By providing myriad insights into the unique ecological information contained in the fossil record, it establishes a new and ambitious basis for the study of evolutionary paleoecology of land ecosystems. A joint undertaking of the Evolution of Terrestrial Ecosystems Consortium at the National Museum of Natural History, Smithsonian Institution, and twenty-six additional researchers, this book begins with four chapters that lay out the theoretical background and methodology of the science of evolutionary paleoecology. Included are a comprehensive review of the taphonomy and paleoenvironmental settings of fossil deposits as well as guidelines for developing ecological characterizations of extinct organisms and the communities in which they lived. The remaining three chapters treat the history of terrestrial ecosystems through geological time, emphasizing how ecological interactions have changed, the rate and tempo of ecosystem change, the role of exogenous "forcing factors" in generating ecological change, and the effect of ecological factors on the evolution of biological diversity. The six principal authors of this volume are all associated with the Evolution of Terrestrial Ecosystems program at the National Museum of Natural History, Smithsonian Institution.
