"The Markagunt and Sevier gravity slides are gigantic landslides that resulted from gravitationally induced catastrophic failure of the southern flank of the Oligocene to Miocene Marysvale volcanic field. Each is nearly 100 km long with runouts over the former land surface >35 km; together they span 7000 km2 and rank among Earth's largest terrestrial landslides. Basal cataclastic layers, injectites, pseudotachylyte, deformed clasts, and a variety of kinematic indicators demonstrate catastrophic emplacement, which was preceded by slow gravitational spreading of the volcanic field. This volume offers a history of their discovery, our current understanding of the gravity slides, and a guide to particularly instructive exposures for which the authors document their conclusions about the size, age, and significant structural features of these newly discovered features"-- Provided by publisher

The last comprehensive review of the fossil vertebrates from the Miocene of Calvert Cliffs was published more than 100 years ago. This volume is a collection of papers that updates some of the geological features of Calvert Cliffs and provides reviews of the fossil biota that includes representatives from the following taxonomic groups: chondrichthyans (chimaeras, shark, skates, and rays), actinopterygians (ray-finned fishes), crocodilians (crocodiles), pinnipeds (seals), and sirenians (sea cows). Peter Vogt, Ralph R. Eshelman, and Stephen J. Godfrey document how the 20-40 m (65-130 feet) high Calvert Cliffs along the Western Shore of Chesapeake Bay continue to yield insights into 18-8 Ma (middle Miocene) geology, marine and terrestrial vertebrate fauna, and origin and evolution of Chesapeake Bay and Calvert Cliffs up to the present. These exposures rank high among the best-known fossiliferous deposits of any age. Bretton W. Kent describes the cartilaginous fish (the chondrichthyan) fauna consisting of 53 species; three chimaeras (ratfishes), 38 sharks, and 12 skates and rays; a fauna rich in large macrophagous sharks and large neritic rays. Giorgio Carnevale and Stephen J. Godfrey present an account of the 38 actinopterygian taxa known from osteological remains and a diverse otolith assemblage of at least 55 taxa. These actinopterygians show an affinity for well-oxygenated muddy and sandy substrates dominated by shallow water species characteristic of the inner shelf, and secondarily by epipelagic taxa. Robert E. Weems details the crocodilians referable to the tomistomine Thecachampsa. The closest living relative is Tomistoma schlegelii, the false-gharial of Southeast Asia. Two species are present: Thecachampsa sericodon and T. antiquus--Provided by publisher.

Coastal exposures of the Santa Cruz Formation in southern Patagonia have been a fertile ground for recovery of Early Miocene vertebrates for more than 100 years. This volume presents a comprehensive compilation of important mammalian groups which continue to thrive today. It includes the most recent fossil finds as well as important new interpretations based on ten years of fieldwork by the authors. A key focus is placed on the paleoclimate and paleoenvironment during the time of deposition in the Middle Miocene Climatic Optimum (MMCO) between twenty and fifteen million years ago. The authors present the first reconstruction of what climatic conditions were like and present important new evidence of the geochronological age, habits and community structures of fossil bird and mammal species. Academic researchers and graduate students in paleontology, paleobiology, paleoecology, stratigraphy, climatology and geochronology will find this a valuable source of information about this fascinating geological formation.

Located at the southwest corner of Lake Turkana in northern Kenya, Lothagam represents one of the most important intervals in African prehistory. Early human remains are restricted in distribution to Africa and the acquisition of an upright bipedal striding gait, the hallmark of humanity, appears to be at least circumstantially linked to the reduction of equatorial forests and the spread of grasslands on that continent. The diverse Lothagam fauna documents the end-Miocene transition from forested to more open habitats that were exploited by grazing horses and antelopes, hippos, giant pigs, and true elephants. It also includes spectacularly complete fossil carnivore skeletons and some of the oldest human remains. Enlisting a team of highly qualified specialists, this book provides the geologic context and dating framework for the Lothagam fossiliferous sequences, describes the immense diversity of vertebrate fossils recovered from the Late Miocene and Early Pliocene sediments, and synthesizes the results to interpret the changing paleoenvironments that prevailed at this site. The book will interest anthropologists, paleontologists, geologists, and anyone interested in human origins. (source: Nielsen Book Data)

Integrated stratigraphy is essential for: detailed paleoecologic studies of critical intervals in Earth history; the calibration of the time scale for global use; and the establishment of Global Stratotype Sections and Points (GSSPs) for the definition of chronostratigraphic boundaries. This work constitutes an example of how interdisciplinary stratigraphic and geochronologic studies are approached with modern methodologies and techniques. It contains numerous unpublished radioisotopic dates of volcano-sedimentary layers interbedded in fossiliferous marine and continental Miocene sequences representing Mediterranean and Pacific environments. Detailed paleontologic data which constitutes the basis for an accurate definition of the Miocene biostratigraphy and the study of the ecologic evolution of Miocene marine environments are also included. This work should be of interest to stratigraphers, paleontologists and sedimentologists plus geologists working in oil companies. (source: Nielsen Book Data)
Focuses on evaporites such as limestone, dolomite, gypsum, and halite, found in the rift and foreland basins of eastern France and northern Spain. By demonstrating that the early environment of the region encouraged the habitation and growth of many forms of life, the text challenges traditional assessments of these areas as harsh, arid and inhospitable to life. It argues that the same evaporitic environment which promoted an abundance of organisms might also preserve their organic remains - producing potentially large amounts of oil. Supplemented by a com prehensive review of both recent and classic research in sedimentology, this text should be of interest to researchers and professionals in oil geology, stratigraphy, paleontology, chemistry and physics.

Introduction-- Features of the fossil soils-- Burial alteration of the fossil soils-- Early to middle Miocene fossil soils of Southweastern Kenya-- Late Miocene fossil soils of Northeastern Pakistan-- Reconstructed life and landscapes of the old world tropics.
(source: Nielsen Book Data)
In this book, the habitats of our apelike ancestors of the Miocene epoch - some 7 to 20 million years ago - are re-examined from the perspective of knowledge yielded by the buried fossil soils in which they have been found. Fossilized soils, or palaeosols, are distinctive layers within a sedimentary or volcanic sequence, and they also can be clues to former ecosystems and other aspects of palaeoenvironments. Here the author characterizes in detail some 20 kinds of palaeosols from the Kenyan and Pakistani localities for the tryopithicane and ramapithicine apes made famous by L.S.B. Leakey and D.R. Pilbeam. The extensive evidence cited allows for the reassessment of vegetation and landscape features of ancient tropical sites that are the source of much of what is known about our remote Miocene ancestors. The text also provides a basis for understanding palaeosols formed in all tropical climates and alluvial settings, and offers a model for future research on human evolution and major events in the geological history of soils. It is a valuable resource for palaeontologists, anthropologists, and soil scientists. (source: Nielsen Book Data)
