This book offers many examples of calcareous microfossils and describes a new microfaunistic record in Argentina. These selected papers of the 11th Argentine Paleontological Congress include micropaleontological studies on material of different geological ages from several sites in Argentina and Colombia. The authors highlight several geological findings and explain the paleoenvironmental changes in Argentina and Colombia.

It is hoped this will stimulate more research in the field of plant micropaleontology in temperate South America. Such research in northern South America has advanced our knowledge immensely (Vander Hammen, 1966), and high rewards await ...

Written by specialists in the field, the papers in this volume explore evolution of animals and plants on the deserts of North America, South America, and Australia. Together, the articles constitute a complete survey of the geological history of the deserts of three continents, the evolution of the animals and plants of those deserts, and their adaptations to the environments in which they live. The first paper, by Otto T. Solbrig, discusses the flora of the South American temperate and semidesert regions, citing numerous genera and reasons that they are found in the different areas. John S. Beard uses the same approach in his discussion of the evolution of Australian desert plants and focuses on western Australian areas. Guillermo Sarmiento appraises the evolution of arid vegetation in tropical America, including the Lesser Antilles and the Coast Range of Venezuela and Colombia. A. R. Main surveys the adaptation of Australian vertebrates to desert conditions and gives examples of how various species of birds, reptiles, and amphibians adapt to their environment in order for the greatest number to survive. James A. MacMahon designates specific communities in the Mojave, Sonoran, and Chihuahuan deserts and discusses the similarity of species of the North American desert mammal faunas found there, while Bobbi S. Low focuses on the evolution of amphibian life histories in the desert and compiles a lengthy table of amphibia comparing egg size, habitat, number of eggs per clutch, and so forth. Finally, W. Frank Blair treats adaptation of anurans to equivalent desert scrub of North and South America and cites various species of frogs and toads that are found in similar areas. The volume also includes an introduction by the editor and an index. Evolution of Desert Biota is the result of a symposium held during the First International Congress of Systematic and Evolutionary Biology in Boulder, Colorado; in August 1973.

This book gathers and updates the most significant advances of the last two centuries and presents an unprecedented micro paleontological study covering more than 20 stratigraphic sections. This information is supplemented by numerous sedimentological observations and analyses, on the basis of which a new lithostratigraphic framework for the Neogene of the Chacoparanense Basin is proposed. The book is structured in an easy-to-read format: Its main section offers a comprehensive review of the current state of knowledge on transgressions in Argentina and similar transgressions in other South American countries, taking into account various key aspects (age, paleoenvironment, micropaleontology, etc.). Secondly, the book presents the main results on the TLP and TEP of the Chacoparanense Basin and the TEP of the Península de Valdés. Lastly, it provides readers with complete stratigraphic profiles (Appendix A), mineralogical analyses (Appendix B), distribution charts (Appendix C), systematics (Appendix D) and plates (Appendix E).

Microfossils are ideally suited to environmental studies because their short generation times allow them to respond rapidly to environmental change. This book represents an assessment of the progress made in environmental micropalaeontology and sets out future research directions. The taxa studied are mainly foraminifera, but include arcellaceans, diatoms, dinoflagellates, and ostracodes. The papers themselves range from reviews of applications of particular taxa to specific case studies.

This book presents extensive and new information on the geomorphology of cratonic areas of southern South America. It includes valuable data relating to recurrent controversies in general geomorphology beyond the boundaries of South America and reveals the great need to integrate many different aspects of geomorphology in regional studies. With the focus on ancient landscapes and especially on planation surfaces it addresses the question of what processes could form such huge features, and how they can be preserved for so long. Many of the papers include maps of planation surfaces or other geomorphic units. The volume brings together an up-to-date, state-of-the-art collection of information on South American geomorphology, and shows beyond doubt that geomorphology is on the same time scale as global tectonics, biological evolution and major climate change. Some of the papers describe ancient geomorphological features of areas that have never been studied or published before, while others describe regions which are totally unknown to the public. The scope of the book extends from tropical latitudes north of the Tropic of Capricorn, south to freezing Patagonia in the “roaring fifties”, more than 3,500 km from north to south. Including over one thousand citations from geological and geomorphological literature, this volume will serve as a starting point for a whole new phase of studies of the fascinating landscape history of southern South America.

How is it that we came to be here? The search for answers to that question has preoccupied humans for millennia. Scientists have sought clues in the genes of living things, in the physical environments of Earth from mountaintops to the depths of the ocean, in the chemistry of this world and those nearby, in the tiniest particles of matter, and in the deepest reaches of space. In Islands of the Cosmos, Dale A. Russell traces a path from the dawn of the universe to speculations about our future on this planet. He centers his story on the physical and biological processes in evolution, which interact to favor more successful, and eliminate less successful, forms of life. Marvelously, these processes reveal latent possibilities in life's basic structure, and propel a major evolutionary theme: the increasing proficiency of biological function. It remains to be seen whether the human form can survive the dynamic processes that brought it into existence. Yet the emergence of the ability to acquire knowledge from experience, to optimize behavior, to conceptualize, to distinguish "good" from "bad" behavior all hint at an evolutionary outcome that science is only beginning to understand.

Earth Sciences, Volume X: Principles of Zoological Micropalaeontology highlights the morphological, phylogenetic and ecological analysis of microfossils. This book is composed of 10 chapters that survey the most important microfossil taxa, their variety of form, evolution, relationships, and distribution. The opening chapter provides an introduction to the historical development of micropalaeontology. The succeeding chapters present the procedures for the collection, preparation, and microstratigraphic analysis of microfossils. The remaining chapters discuss the morphological, ecological, and phylogenetic properties of Radiolaria, Thekamoebae, Foraminifera, Tintinnina, Incertae sedis, Chitinozoa, and Hystrichosphere microfossils. This book is intended as a textbook and as a manual for practicing micropalaeontologists.
