Book Description
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.

Book Description
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.

Book Description
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.

Book Description
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)
