Birds is the first book to examine bird remains in archaeology and anthropology. Providing a thorough review of the literature on this topic, it also serves as a guide to the methods of study of bird remains from the past and covers a wide range of topics, including anatomy and osteology, taphonomy, eggs, feathers, and, bone tools. It examines the myriad ways in which people have interacted with birds in the past. The volume also includes discussion on the consumption of wild birds, the domestication of birds, cockfighting and falconry, birds in ritual and religion, and the role of birds in ecological reconstruction, providing an up-to-date survey of current knowledge on these topics. Birds will be an invaluable resource for undergraduate and graduate students interested in zooarchaeology and human-animal relations, as well as professional zooarchaeologists, archaeologists, and anthropologists interested in birds and people of the past.

This volume is a record of the 6th International Conference on the Origins of Life and the 3rd Meeting of the International Society for the Study of the Origins of Life. The conference was held under the auspices of the Israel Academy of Sciences and Humanities at Jerusalem from June 22nd to June 27th 1980. A few weeks prior to the conference, Academician Aleksander Ivanovich Oparin passed away. Oparin, the father and founder of the study of the origins of life, proposed over 50 years ago that modern biological molecules had abidogical origins in the past, thus the beginning of life on Earth was preceded by a long period of abiogenic molecular evolution. Oparin was planning to report on his latest work in the opening session of the meeting - "Natural Selection: A Leading Factor in Transition from the Non-Living Matter to Life." This lecture will never be delivered. In Hebrew we say of those who have died "may their memory be bound with the bonds of eternal life." For Aleksander Ivanovich Oparin those words have particular significance, for surely his pioneering work will endure as long as the spirit of scientific enquiry prevails. This meeting was dedicated to the memory of Aleksander Ivanovich Oparin.

Palaeomagnetism and archaeomagnetism are fascinating specialized studies because they are applicable to such a wide range of problems in geology, archaeology and geophysics. They can also be undertaken cheaply, when compared with most other geophysical techniques, and, at first sight, simply. In fact, real comprehension of the magnetic processes that have occurred in rocks and other types of material over several thousands or many millions of years is still extremely difficult to assess and measure. On this basis, this book cannot explain all such features, nor can it attempt to cover all the actual and potential applications of the method. All that can be attempted is to give an impression of the ways in which such techniques can be used in a wide variety of fields, and how these techniques are usually applied. The magnetization of rocks is, in fact, one of the earliest of the true sciences, but we are still not in a position to answer many of the problems posed. Consequently some of the examples given of applications are, essentially, state-of-the-art comments, rather than being a review as such. The changing position of the geomagnetic poles with time is still not adequately defined, for example, and some of the more recent conventional views are given, although the emphasis is placed on more subjective, probably more controversial, evaluations.

This volume reviews the meaning of taxonomic statements and considers our present knowledge regarding the number and characteristics of species among living and extinct primates, including man and his ancestors. They also examine the relationship of behaviour changes and selection pressures in evolutionary sequences. First published in 1964.

The return of Halley's Cornet in 1986 has generated much ex citement in the scientific community with preparations already afoot for an International Cornet Watch and a cornet launch by the European Space Community, the Japanese and Soviet Space Scientists. The meet ing held at the University of Maryland in October 1980 was primarily stimulated by the preparations for further study of this cornet and by one of the most important unanswered questions related to comets, name ly, whether they may have made a eontribution to the origin of life on earth. Our un"derstanding of the role of comets in the origin of life must necessarily come from our studies of the astronomy and the chem istry of comets. Some clues to the processes which led to the for mation of organic molecules and eventually to the appearance of life have come from these studies of comets, perhaps the most ancient of all objects in our solar system. Whether there is, however, a biology of comets still remains to be seen, although some claims have been made that perhaps comets might themselves provide an environment for even the beginnings of life. Scientists with the latest available information on comets and differing opinions as to the role of comets in the origin of life attended this symposium. The formal papers presented are now being made available to the students of chemical evolution within the pages of this volume."

This volume is a collection of papers presented to Professor Tom Barnard by former students, colleagues and friends to mark thirty-two years of teaching and research in micropalaeontology at University College London. This period represents the major part of Tom Barnard's career with microfossils, which actually began rather earlier, but in 1949 his first postgraduate students were registered. Since then some 150 students have worked for higher degrees studying foraminifera, ostracods, calcareous nannofossils, dino of Research flagellates and palynomorphs, in company with a series Assistants and Visiting Scientists. The nature of micropalaeontology at 'UC' under Tom Barnard has always been unashamedly biostratigraphical. As a result many students have entered and continue to enter the petroleum industry, not least of all because their mentor has always had a pragmatic view of academic research and its direction. Despite this emphasis, with a particular attention to Mesozoic foraminifera, a major investigation of Recent Caribbean foraminiferal faunas has been carried out and most recently MSc classes have worked with material from the continental shelf of southern Africa. Work with Mesozoic ostracods was initiated in 1956 and during the past decade a growing number of students have concentrated on calcareous nannofossils. A book sum marising the results of biostratigraphical work with nannofossils is at present in the press (Lord, A. R. (ed. ) A stratigraphical index of calcareous nanno fossils. Chichester: Ellis Horwood)."

British Fossil reptile sites are of international importance since they include remains that fill the time gaps poorly known elsewhere. They include rich classic reptile beds which have been the source of dozens of important specimens. This volume details all those sites that have yielded fossil reptiles. The fifty most important localities are described in detail and an extensive bibliography of everything published on British Fossil reptiles since 1676 is provided.

Precambrian stromatolites have received in depth, consideration from geologists and paleontologists; they were indeed searching for biosedimentary structures that were sufficiently characteristic and widely distributed to be considered as useful tools for stratigraphic correlation. Silicified stromatolites are also of interest as they contain preserved traces of ancient life. Calcareous Phanerozoic stromatolites have not received very much attention from geologists. Logan's too schematic morphological classification of 1964, was not so helpful to the knowledge of Phanerozoic stromatolites because neither their morphology nor their microstructure were studied in the same detail in which Proterozoic stromatolites have now been described. We therefore know little about the Phanerozoic stromatolites which, do, however, show an interesting range of diversification. A major questions stiII remaining to be answered include the history of stromatolite development and wether their morphology has "evolved" in addition to detailed information concerning Cenozoic nonmarine stromatolites which precipitate carbonate and the Recent giant stromatolites which trap particles. For these reasons Claude Monty, in 1981, launched the first volume of what was going to be a series on "Phanerozoic stromatolites" in order to describe their morphology, microstructure and paleoecology and to present them in their stratigraphic context.

Gideon Mantell and the Discovery of Dinosaurs is a scholarly yet accessible biography--the first in a generation--of a pioneering dinosaur hunter and scholar. Gideon Mantell discovered the Iguanodon (a famous tale set right in this book) and several other dinosaur species, spent over twenty-five years restoring Iguanodon fossils, and helped establish the idea of an Age of Reptiles that ended with their extinction at the conclusion of the Mesozoic Era. He had significant interaction with such well-known figures as James Parkinson, Georges Cuvier, Charles Lyell, Roderick Murchison, Charles Darwin, and Richard Owen. Dennis Dean, a well-known scholar of geology and the Victorian era, here places Mantell's career in its cultural context, employing original research in archives throughout the world, including the previously unexamined Mantell family papers in New Zealand.

Living material contains about twenty different sorts of atom combined into a set of relatively simple molecules. Astrobiologists tend to believe that abiotic mater ial will give rise to life in any place where these molecules exist in appreciable abundances and where physical conditions approximate to those occurring here on Earth. We think this popular view is wrong, for it is not the existence of the building blocks of life that is crucial but the exceedingly complicated structures in which they are arranged in living forms. The probability of arriving at biologically significant arrangements is so very small that only by calling on the resources of the whole universe does there seem to be any possibility of life originating, a conclusion that requires life on the Earth to be a minute component of a universal system. Some think that the hugely improbable transition from non-living to living mat ter can be achieved by dividing the transition into many small steps, calling on a so-called 'evolutionary' process to bridge the small steps one by one. This claim turns on semantic arguments which seek to replace the probability for the whole chain by the sum of the individual probabilities of the many steps, instead of by their product. This is an error well known to those bookies who are accustomed to taking bets on the stacking of horse races. But we did not begin our investigation from this point of view.

In 1971 I published a review of ichnology other concentrating only on traces made (Houston AAPG: SEPM Trace Fossil Field by a certain group of organisms, regardless Trip Guidebook) that I thought could be of their setting. Nevertheless, needless re dundancy has hopefully been eliminated. expanded rather easily into a worthwhile Some of the chapters are more special book on the subject.

As I began to out somewhat less familiar or "comprehensible" line the chapters in more detail, however, than others-depending upon the reader's it soon became apparent that my personal own interests and background.

I quickly de ous chapters stem from the simple fact cided that a better book could be produced that a considerably greater backlog of pre by soliciting specific contributions from vious work is available in certain facets of other workers who, collectively, had first ichnology than in others. But we hope hand experience with virtually every aspect that all of the chapters will prove to be use of the field. That became the actual plan, ful to anyone wishing to delve 'into them. the result of which is this book."

South America is a unique place where a number of past climate archives are ava- able from tropical to high latitude regions. It thus offers a unique opportunity to explore past climate variability along a latitudinal transect from the Equator to Polar regions and to study climate teleconnections. Most climate records from tropical and subtropical South America for the past 20,000 years have been interpreted as local responses to shift in the mean position and intensity of the InterTropical Conv- gence Zone due to tropical and extratropical forcings or to changes in the South American Summer Monsoon. Further South, the role of the Southern Hemisphere westerly winds on global climate has been highly investigated with both paleodata and coupled climate models. However the regional response over South America during the last 20,000 years is much more variable from place to place than pre- ously thought. The factors that govern the spatial patterns of variability on millennial scale resolution are still to be understood. The question of past natural rates and ranges of climate conditions over South America is therefore of special relevance in this context since today millions of people live under climates where any changes in monsoon rainfall can lead to catastrophic consequences.

This is a book for beginners. Not geological beginners, because an introductory course in paleontology and some knowledge of the petrographic microscope is assumed, but for beginners in the study of the petrography of fossil constituents in sedimentary rocks. Fossils are studied for various reasons: 1) to provide chron ologic (time) frameworks, 2) to delineate rock units and ancient environments, or 3) to understand the past development (evolu tion) of living plants and animals. All of these uses may be at tained through petrographic studies of thin sections of fossils embedded in sedimentary rocks. Some knowledge of the appear ance of fossils in thin section is also fundamental for general stratigraphic studies, biofacies analyses, and is even useful in studying some metamorphic rocks. Commonly, fossils are essen tial for the delineation of carbonate rock types (facies or bio facies). We have written this book for sedimentary petrologists and stratigraphers, who routinely encounter fossils as part of their studies but who are not specialists in paleontology, and for students who are seeking a brief review and an introduction to the literature of the petrography of fossiliferous sedimentary rocks. Although experienced paleontologists may be appalled by the many generalized statements on size, shape, and principal fossil characters recited herein, we counter that we have had some success in introducing non-paleontologically oriented geologists to the use and identification of fossil constituents without using excessive paleontological terminology and detailed systematics."

In Plants and the K-T Boundary, two of the world's leading experts in palynology and paleobotany provide a comprehensive account of the fate of land plants during the 'great extinction' about 65 million years ago. They describe how the time boundary between the Cretaceous and Paleogene Periods (the K-T boundary) is recognized in the geological record, and how fossil plants can be used to understand global events of that time. There are case studies from over 100 localities around the world, including North America, China, Russia and New Zealand. The book concludes with an evaluation of possible causes of the K-T boundary event and its effects on floras of the past and present. This book is written for researchers and students in paleontology, botany, geology and Earth history, and everyone who has been following the course of the extinction debate and the K-T boundary paradigm shift.

This volume is the fourth in the series of the Proceedings of the College Park Colloquia on Chemical Evolution. These Colloquia, and the resulting Proceedings, are presented in the interest of fostering the impact of the interdisciplinary nature of chemical evolu tion on contemporary scientific thought. vii EDITORS'INTRODUCTION The Fourth College Park Colloquium on Chemical Evolution was held on October 18 - 20, 1978 at the University of Maryland. The meeting, supported by the National Aero nautics and Space Administration and the National Science Foundation, centered on the variable environments, both past and present, in which living organisms have survived, grown, and evolved - the limits of life. Previous colloquia had emphasized the Giant Planets (1974) 1, Early Life during the Precambrian (1975)2 and Comparative Planetology (1976)3. The College Park Colloquia have been noted for the broad interdisciplinary nature of the training and interests of the participants. The fourth meeting was no ex ception with the participation of approximately 85 researchers, representing many academic fields. As with previous meetings, the interdisciplinary approach to the question of the limits of life encouraged the exchange of knowledge and information. A major scientific aspiration is to understand why living systems are restricted to certain environments."

Quantitative Paleozoology describes and illustrates how the remains of long-dead animals recovered from archaeological and paleontological excavations can be studied and analyzed. The methods range from determining how many animals of each species are represented to determining whether one collection consists of more broken and more burned bones than another. All methods are described and illustrated with data from real collections, while numerous graphs illustrate various quantitative properties.

Primate Biogeography is a subject rarely addressed as a discipline in its own right. This comprehensive source introduces the reader to Primate Biogeography as a discipline. It highlights the many factors that may influence the distribution of primates, and reveals the wide range of approaches that are available to understanding the distribution of this order. The biogeography of primates in the past is a major component of our understanding of their evolutionary history and is an essential component of conservation biology. This book will appeal to primatologists, physical anthropologists, zoologists, and undergraduates in these areas.

The history of scientific research and technological development is replete with examples of breakthroughs that have advanced the frontiers of knowledge, but seldom does it record events that constitute paradigm shifts in broad areas of intellectual pursuit. One notable exception, however, is that of spin electronics (also called spintronics, magnetoelectronics or magnetronics), wherein information is carried by electron spin in addition to, or in place of, electron charge. It is now well established in scientific and engineering communities that Moore's Law, having been an excellent predictor of integrated circuit density and computer performance since the 1970s, now faces great challenges as the scale of electronic devices has been reduced to the level where quantum effects become significant factors in device operation. Electron spin is one such effect that offers the opportunity to continue the gains predicted by Moore's Law, by taking advantage of the confluence of magnetics and semiconductor electronics in the newly emerging discipline of spin electronics. From a fundamental viewpoine, spin-polarization transport in a material occurs when there is an imbalance of spin populations at the Fermi energy. In ferromagnetic metals this imbalance results from a shift in the energy states available to spin-up and spin-down electrons. In practical applications, a ferromagnetic metal may be used as a source of spin-polarized electronics to be injected into a semiconductor, a superconductor or a normal metal, or to tunnel through an insulating barrier.

This book offers exchanges between the fields of paleontology and zoology as patterns of biodiversity have long attracted the attention of both biologists and paleontologists. It covers the development of isolated island faunas, paleogeography and zoomorphology. The book shows that patterns are not always what they seem if looked at without a spatial or temporal reference.

Recent years have witnessed exciting and important scientific breakthroughs in the study of Neanderthals and their place in human evolution which have transformed our appreciation of this group s paleobiology and evolution. This volume presents cutting-edge research by leading scientists re-examining the major debates in Neanderthal research with the use of innovative state-of-the art methods and exciting new theoretical approaches.

Topics addressed include the re-evaluation of Neanderthal anatomy, inferred adaptations and habitual activities, developmental patterns, phylogenetic relationships, and the Neanderthal extinction; new methods include computer tomography, 3D geometric morphometrics, ancient DNA and bioenergetics. The diverse contributions offer fresh insights and advances in Neanderthal and modern human origins research.

This volume includes a general description of the Portuguese Cenozoic basins in the Iberian tectonic context. The main stratigraphic units, including sedimentological, stratigraphical and palaeontological data, are characterized. Correlations between different sectors are presented as well as general paleogeographical evolution maps. The volume includes a general bibliography concerning the Cenozoic of Portugal.

An understanding of the uniquely human behavior of stone tool making tackles questions about hominins' ability to culturally transmit and expand their base of social and practical knowledge and their cognitive capacities for advanced planning. The appearance of stone tools has often been viewed as a threshold event, impacting directly and profoundly the later course of cultural and social evolution. Alternatively, it has been understood as a prelude to significant succeeding changes in behavioral, social and biological evolution of hominins. This book presents a series of recent enquiries into the technological and adaptive significance of Oldowan stone tools. While anchored in a long research tradition, these studies rely on recent discoveries and innovative analyses of the archaeological record of ca. 2.6-1.0 million years ago in Africa and Eurasia, dealing with the earliest lithic industries as manifestations of hominin adaptations and as expressions of hominin cognitive abilities.

Although the name Pithecanthropus is now seldom used, there are few who study the origin of our species who will fail to recognise the historical place of the usage and its association with Eugene Dubois. During the last thirty or forty years, Australopithecus and its African context has tended to draw attention from the early work on our origins in Java. It is now increasingly common to hear the term 'pithecanthropine' used only to indicate the Asian or Far Eastern examples of Homo erectus which, although probably derived from African ancestry, have some features that in the opinion of some experts may justify their being considered distinctive. This discussion is not within the pages that follow which deal extensively with the work of Eugene Dubois. He was an extraordinary man who did as much as any person since to put the great antiquity of our ancestors firmly in the public domain. Dubois became involved with the study of human origins from a medical and anatomical background as have many since. The jealousies and professional pressures that we think of as a phenomenon of the post-war years were clearly a major factor in deciding the future of his career.
