Download or read book Oligocene Echinoids of North Carolina written by Porter M. Kier and published by . This book was released on 1997 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: Oligocene echinoids are rare, which makes important this material from three quarries in North Carolina. Three species occur in the state quarry at Pollocksville: Psammechinus carolinensis, new species, Maretia carolinensis, new species, and Agassizia sp. At the New Bern quarry occur Rhyncholampas gouldii (Bouv) newbernensis, new subspecies, Agassizia mossomi Cooke, Psammechinus carolinensis, new species, Dixieus dixie (Cooke), Clypeaster rogersi (Morton), and Maretia sp. Periarchus lyelli (Conrad) is found in underlying Eocene beds. The Belgrade quarry fauna consists of Arbia aldrichi (Clark), Gagaria mossomi (Cooke), Echinocyamus wilsoni, new species, and Agassizia mossomi Cooke. These echinoids indicate a middle to late Oligocene age for the Trent Formation (= River Bend) and Belgrade Formation (= River Bend).

Available in PDF, EPUB and Kindle. Book excerpt: The marine Eocene-Oligocene transition of 34 million years ago was a critical turning point in Earth's climatic history, when the warm, high-diversity "greenhouse" world of the early Eocene ceded to the glacial, "icehouse" conditions of the early Oligocene. This book surveys the advances in stratigraphic and paleontological research and isotopic analysis made since 1989 in regard to marine deposits around the world. In particular, it summarizes the high-resolution details of the so-called doubthouse interval (roughly 45 to 34 million years ago), which is critical to testing climatic and evolutionary hypotheses about the Eocene deterioration. The authors' goals are to discuss the latest information concerning climatic and oceanographic change associated with this transition and to examine geographic and taxonomic patterns in biotic turnover that provide clues about where, when, and how fast these environmental changes happened. They address a range of topics, including the tectonic and paleogeographic setting of the Paleogene; specific issues related to the stratigraphy of shelf deposits; advances in recognizing and correlating boundary sections; trends in the expression of climate change; and patterns of faunal and floral turnover. In the process, they produce a valuable synthesis of patterns of change by latitude and environment.

Download or read book Phylogenetic Revision of the Fish Families Luvaridae and Kushlukiidae Acanthuroidei with a New Genus and Two New Species of Eocene Luvarids written by Aleksandr Fedorovich Bannikov and published by . This book was released on 1995 with total page 490 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ten synapomorphies are described that support the proposed sister group relationship of the Eocene Kushlukiidae and the Eocene to Recent Luvaridae as the superfamilial clade Luvaroidea at the node between the siganid and zanclid+acanthurid clades of acanthuroid fishes. The Kushlukiidae previously have been known only on the basis of Kushlukia permira Danilchenko from the Eocene of Turkmenistan, but another species of that age is shown to have been present in India; the latter is not given a new specific name because the two specimens of it are only fragments. In addition to the well known Recent species Luvarus imperialis, three fossil species have been referred to the Luvaridae: Proluvarus necopinatus Danilchenko from the Eocene of Turkmenistan is here recognied as a valid species of Luvarus, with Proluvarus becoming a junior synonym of Luvarus; Eoluvarus bondei Sahni and Choudhary from the Eocene of India is shown to be not a luvarid but, rather, a member of the fossil perciform family Exelliidae, the affinities of which family are poorly understood; Luvarus praeimperialis Arambourg from the Oligocene of Iran is shown to be not a luvarid but, rather, a representative of the new genus Aluvarus of such uncertain affinity that we simply place it incertae sedis among the percomorphs. Among the materials used by Danilchenko in the description of Proluvarus necopinatus only the holotype and the five other largest specimens (about 326-495 mm SL) represent that species. All of the other specimens are smaller than about 215 mm SL and represent two new species of a new genus of luvarid, Avitoluvarus dianae and A. mariannae. Numerous derived features are used to define both the Kushlukiidae and Luvaridae. Within the Luvaridae, the preponderance of derived features is found in Luvarus, whereas Avitoluvarus has only two unequivocal synapomorphies. The Luvaroidea, therefore, are represented by the Eocene Kushlukiidae with one genus and two species (Kushlukia permira and K. sp.) and the Luvaridae with one Eocene genus with two species (Avitoluvarus dianae and A. mariannae) and one genus, Luvarus, with one Eocene species, L. necopinatus, and one Recent species, L. imperialis.

Available in PDF, EPUB and Kindle. Book excerpt: A fascinating study of the thousands of new animal species that walked in the footsteps of the dinosaurs—and the climate changes that brought them forth. The fascinating group of animals called dinosaurs became extinct some 65 million years ago (except for their feathered descendants). In their place evolved an enormous variety of land creatures, especially mammals, which in their way were every bit as remarkable as their Mesozoic cousins. The Age of Mammals, the Cenozoic Era, has never had its Jurassic Park, but it was an amazing time in earth’s history, populated by a wonderful assortment of bizarre animals. The rapid evolution of thousands of species of mammals brought forth many incredible creatures―including our own ancestors. Their story is part of a larger story of new life emerging from the greenhouse conditions of the Mesozoic, warming up dramatically about 55 million years ago, and then cooling rapidly so that 33 million years ago the glacial ice returned. The earth’s vegetation went through equally dramatic changes, from tropical jungles in Montana and forests at the poles. Life in the sea underwent striking evolution reflecting global climate change, including the emergence of such creatures as giant sharks, seals, sea lions, dolphins, and whales. Engaging and insightful, After the Dinosaurs is a book for everyone who has an abiding fascination with the remarkable life of the past.
Download or read book The Geology of the Carolinas written by J. Wright Horton and published by Univ. of Tennessee Press. This book was released on 1991 with total page 432 pages. Available in PDF, EPUB and Kindle. Book excerpt: To celebrate its fiftieth anniversary, the Carolina Geological Society invited forty-three authors to contribute to the creation of The Geology of the Carolinas. The only comprehensive, modern treatment of the subject, the volume has been prepared for a diverse readership ranging from undergraduate students to specialists in the fields of geology and related earth sciences. Following the editors' general introduction are chapters on Precambrian and Paleozoic metamorphic and igneous rocks of the Appalachian Blue Ridge and Piedmont; rocks of early Mesozoic rift basins, formed just before the opening of the Atlantic Ocean; Cretaceous and Tertiary sedimentary deposits of the Atlantic Coastal Plain; Quaternary geology and geomorphology; Cenozoic tectonism, including evidence for the recurrence of large earthquakes near Charleston; and an overview of mineral resources in the Carolinas. The book includes an index of field guides produced by the society and a thorough bibliography. By introducing exciting new concepts and focusing on challenging problems on the frontiers of research, this authoritative book will stimulate research in the years to come. The Editors: J. Wright Horton, Jr., is a research geologist for the United States Geological Survey in Reston, Virginia. Victor A. Zullo is a professor of geology at the University of North Carolina at Wilmington.

This book was released on 2012-12-06 with total page 488 pages. Available in PDF, EPUB and Kindle. Book excerpt: From the Foreword: "Predator-prey interactions are among the most significant of all organism-organism interactions....It will only be by compiling and evaluating data on predator-prey relations as they are recorded in the fossil record that we can hope to tease apart their role in the tangled web of evolutionary interaction over time. This volume, compiled by a group of expert specialists on the evidence of predator-prey interactions in the fossil record, is a pioneering effort to collate the information now accumulating in this important field. It will be a standard reference on which future study of one of the central dynamics of ecology as seen in the fossil record will be built." (Richard K. Bambach, Professor Emeritus, Virginia Tech, Associate of the Botanical Museum, Harvard University)
