A small set of fossilized bones discovered almost thirty years ago led paleontologist Sankar Chatterjee on a lifelong quest to understand their place in our understanding of the history of life. They were clearly the bones of something unusual, a bird-like creature that lived long, long ago in the age of dinosaurs. He called it Protoavis, and the animal that owned these bones quickly became a contender for the title of "oldest known bird." In 1997, Chatterjee published his findings in the first edition of The Rise of Birds. Since then Chatterjee and his colleagues have searched the world for more transitional bird fossils. And they have found them. This second edition of The Rise of Birds brings together a treasure trove of fossils that tell us far more about the evolution of birds than we once dreamed possible. With no blind allegiance to what he once thought he knew, Chatterjee devours the new evidence and lays out the most compelling version of the birth and evolution of the avian form ever attempted. He takes us from Texas to Spain, China, Mongolia, Madagascar, Australia, Antarctica, and Argentina. He shows how, in the "Cretaceous Pompeii" of China, he was able to reconstruct the origin and evolution of flight of early birds from the feathered dinosaurs that lay among thousands of other amazing fossils. Chatterjee takes us to where long-hidden bird fossils dwell. His compelling, occasionally controversial, revelations - accompanied by spectacular illustrations - are a must-read for anyone with a serious interest in the evolution of "the feathered dinosaurs," from vertebrate paleontologists and ornithologists to naturalists and birders.
Late Quaternary Environmental Change: Physical and Human
Perspectives
Throughout our history, humans have been captivated by mythic beasts and legendary creatures. Tales of Bigfoot, the Yeti, and the Loch Ness monster are part of our collective experience. Now comes a book from two dedicated investigators that explores and elucidates the fascinating world of cryptozoology. Daniel Loxton and Donald R. Prothero have written an entertaining, educational, and definitive text on cryptids, presenting the arguments both for and against their existence and systematically challenging the pseudoscience that perpetuates their myths. After examining the nature of science and pseudoscience and their relation to cryptozoology, Loxton and Prothero take on Bigfoot; the Yeti, or Abominable Snowman, and its cross-cultural incarnations; the Loch Ness monster and its highly publicized sightings; the evolution of the Great Sea Serpent; and Mokele Mbembe, or the Congo dinosaur. They conclude with an analysis of the psychology behind the persistent belief in paranormal phenomena, identifying the major players in cryptozoology, discussing the character of its subculture, and considering the challenge it poses to clear and critical thinking in our increasingly complex world.
The echinoderms are an ideal group to understand evolution from a holistic, interdisciplinary framework. The genetic regulatory networks underpinning development in echinoderms are some of the best known for any model group. Additionally, the echinoderms have an excellent fossil record, elucidating in in detail the evolutionary changes underpinning morphological evolution. In this Element, the echinoderms are discussed as a model group for molecular palaeobiological studies, integrating what is known of their development, genomes, and fossil record. Together, these insights shed light on the molecular and morphological evolution underpinning the vast biodiversity of echinoderms, and the animal kingdom more generally.
Based at the Parisian Museum of Natural History, Cuvier was able to compare the fossil bones he dug from the quarries of Montmartre with those of animals alive today. Guided by the principle of correlation, that all the parts of an animal must cohere, and by analogy, with living species, Cuvier boldly reconstructed extinct creatures from the incomplete skeletons he unearthed. This process is described in his Essay on the Theory of the Earth.
Covering a wide area of the London and Hampshire basins, the London Clay has been famous for over two hundred years as one of the richest Eocene strata in the country. In this work, first published between 1849 and 1858, Fellows of the Royal Society Richard Owen (1804-92) and Thomas Bell (1792-1880) describe their findings from among the reptilian fossils found there. The book is divided into four parts, covering chelonian, crocodilian, lacertilian and ophidian fossils, and includes an extensive section of detailed illustrations. Using his characteristic 'bone to bone' method and an emphasis on taxonomy, Owen draws some significant conclusions; he shows that some of Cuvier's classifications were wrongly extended to marine turtles, and adds to the evidence for an Eocene period much warmer than the present. The work is a fascinating example of pre-Darwinian palaeontology by two scientists later much involved in the evolutionary controversy.
Radiolarians in the Sedimentary Record presents the current state of knowledge on fossil radiolarians. The author discusses the record, as well as new integrated taxonomic systems at the family level. The book provides comprehensive coverage of the fossil record of these unicellular organisms. It also discusses their important role in the history of the Earth and their development of the biosphere. This text will prove indispensable for graduate students and researchers in geology, oceanography and earth sciences.
Ecologist Paul Colinvaux's past several years in the Amazon yield this manual written both in English and Portuguese. Consisting in part of illustrations of the principal pollen types that have been found and identified in the sediments of Amazonian lakes, this book should prove a useful tool for ecologists and climate modellers. The manual also contains brief reviews of pioneering pollen work in the Amazon to date, as well as sections on pollen methods, pollen statistics, paleoecology, and lake coring methods.
Fossil crinoids are exceptionally suited to deep-time studies of community paleoecology and niche partitioning. By merging ecomorphological trait and phylogenetic data, this Element summarizes niche occupation and community paleoecology of crinoids from the Bromide fauna of Oklahoma (Sandbian, Upper Ordovician). Patterns of community structure and niche evolution are evaluated over a ~5 million-year period through comparison with the Brechin Lagerstatte (Katian, Upper Ordovician). The authors establish filtration fan density, food size selectivity, and body size as major axes defining niche differentiation, and niche occupation is strongly controlled by phylogeny. Ecological strategies were relatively static over the study interval at high taxonomic scales, but niche differentiation and specialization increased in most subclades. Changes in disparity and species richness indicate the transition between the early-middle Paleozoic Crinoid Evolutionary Faunas was already underway by the Katian due to ecological drivers and was not triggered by the Late Ordovician mass extinction.
This volume offers comprehensive and up-to-date information on research in many different disciplines which give an overall insight into the environmental history of Africa.
Olduvai Groge is a valley in the Serengeti Plains at the western margin of the Eastern Rift Valley in northern Tanzania. The formations discussed in this volume, Beds I and II, were deposited in the Lower and Middle Pleistocene and have yielded large quantities of the remains of early man, in the form of bones and stone tools and evidence of the environment in which they lived. Bed I, in which remains of Australopithecus boisei and Homo habilis have been found, is firmly dated between 1.9 million years for the lowest level and 1.65 million years for a level below the top. This third volume describes the excavations. In Part I, starting with the lowest levels and devoting a chapter to each main level, Dr Leakey describes the actual process of excavation and the finding of the principal remains. In Part II, Dr Leakey describes the circumstances of the discovery of the hominid skeletal remains. These range from purposive excavation to accidental discovery while collecting small stones for mixing in concrete. Finally, mammalian bones, as tools and as food remains are discussed.
Studies of Sr isotopic composition of thousands of samples of marine sediments and fossils have yielded a curve of 87Sr/86Sr versus age for seawater Sr that extends back to 1 billion years. The ratio has fluctuated with large amplitude during this time period, and because the ratio is always uniform in the oceans globally at any one time, it is useful as a stratigraphic correlation and age-dating tool. The ratio also appears to reflect major tectonic and climatic events in Earth history and hence provides clues as to the causes, timing, and consequences of those events. The seawater 87Sr/86Sr ratio is generally high during periods marked by continent-continent collisions, and lower when continental topography is subdued, and seafloor generation rates are high. There is evidence that major shifts in the seawater ratio can be ascribed to specific orogenic events and correlate with large shifts in global climate.
This book is a collection of papers presented in the symposia, held in Beijing, on palaeontology and historical geology. The papers deal with different topics, providing information on Palaeobiogeography and Palaeoecology of Asian countries, their faunal content, and fossil preservation.
IDEAL, the International Decade for East African Lakes, is a ten-year multi-national, multi-disciplinary investigation of the biological, geological, chemical, and physical limnology of the East African Lakes, taking into special account the Great Lakes of the East African Rift Valley and the climatology and paleoclimatology of the Rift Valley itself. The selected papers in this book serve as baseline knowledge for this intensive examination, with most of the contributing authors already actively researching these lakes. The oldest in the world and the largest on the continent, the lakes are vital resources for the indigenous populations of their basins. They are unique not only in their diverse populations of endemic species of fish and invertebrates, but in their sensitivity to climatic change, unusual circulation dynamics and water-column chemistry in relation to higher altitudes, and continuous record of climatic change in tropical Africa. This volume provides an overview of our current knowledge of the lakes combined with the most recent results of specific research efforts by African, American, and European investigators. Included also are some discussions on the impact of man, as well as comprehensive bibliographies.
The burnt-red badlands of Montana's Hell Creek are a vast graveyard of the Cretaceous dinosaurs that lived 68 million years ago. Those hills were, much later, also home to the Sioux, the Crows, and the Blackfeet, the first people to encounter the dinosaur fossils exposed by the elements. What did Native Americans make of these stone skeletons, and how did they explain the teeth and claws of gargantuan animals no one had seen alive? Did they speculate about their deaths? Did they collect fossils? Beginning in the East, with its Ice Age monsters, and ending in the West, where dinosaurs lived and died, this richly illustrated and elegantly written book examines the discoveries of enormous bones and uses of fossils for medicine, hunting magic, and spells. Well before Columbus, Native Americans observed the mysterious petrified remains of extinct creatures and sought to understand their transformation to stone. In perceptive creation stories, they visualized the remains of extinct mammoths, dinosaurs, pterosaurs, and marine creatures as Monster Bears, Giant Lizards, Thunder Birds, and Water Monsters. Their insights, some so sophisticated that they anticipate modern scientific theories, were passed down in oral histories over many centuries. Drawing on historical sources, archaeology, traditional accounts, and extensive personal interviews, Adrienne Mayor takes us from Aztec and Inca fossil tales to the traditions of the Iroquois, Navajos, Apaches, Cheyennes, and Pawnees. Fossil Legends of the First Americans represents a major step forward in our understanding of how humans made sense of fossils before evolutionary theory developed.
This exciting new textbook examines the concepts of evolution as the underlying cause of the rich diversity of life on earth-and our danger of losing that rich diversity. Written as a college textbook, The Diversity and Evolution of Plants introduces the great variety of life during past ages, manifested by the fossil record, using a new natural classification system. It begins in the Proterozoic Era, when bacteria and bluegreen algae first appeared, and continues through the explosions of new marine forms in the Helikian and Hadrynian Periods, land plants in the Devonian, and flowering plants in the Cretaceous. Following an introduction, the three subkingdoms of plants are discussed. Each chapter covers one of the eleven divisions of plants and begins with an interesting vignette of a plant typical of that division. A section on each of the classes within the division follows. Each section describes where the groups of plants are found and their distinguishing features. Discussions in each section include phylogeny and classification, general morphology, and physiology, ecological significance, economic uses, and potential for research. Suggested readings and student exercises are found at the end of each chapter.
Imaging and visualizing fossils in three dimensions with tomography is a powerful approach in paleontology. Here, the authors introduce select destructive and non-destructive tomographic techniques that are routinely applied to fossils and review how this work has improved our understanding of the anatomy, function, taphonomy, and phylogeny of fossil echinoderms. Building on this, this Element discusses how new imaging and computational methods have great promise for addressing long-standing paleobiological questions. Future efforts to improve the accessibility of the data underlying this work will be key for realizing the potential of this virtual world of paleontology.
The study of echinoid evolution, diversity, and ecology has always suffered from the fact that they are represented by taxa showing widely differing architectural designs of their multi-plated skeletons, inhabiting a large range of marine paleoenvironments, which result in highly varying taphonomic biases dictating their presence and recognition. This Element addresses the taphonomy of echinoids and includes: a general introduction to the morphological features of echinoids that play a role in their preservation; a review of processes which play an important role in the differential preservation of both regular and irregular echinoids including predation and transport; a summary of taphonomic pathways included in actualistic studies for recent sea urchins and then reconstructed for fossil taxa; and finally, a case study of the variation of echinoid taphonomy across a shelf gradient using the rich Miocene echinoid fauna of Sardinia.
Molybdenum (Mo) is a widely used trace metal for investigating redox conditions. However, unanswered questions remain that concentration and bulk isotopic analysis cannot specially answer. Improvements can be made by combining new geochemical techniques to traditional methods of Mo analysis. In this Element, we propose a refinement of Mo geochemistry within aquatic systems, ancient rocks, and modern sediments through molecular geochemistry (systematically combining concentration, isotope ratio, elemental mapping, and speciation analyses). Specifically, to intermediate sulfide concentrations governing Mo behavior below the 'switch-point' and dominant sequestration pathways in low oxygen conditions. The aim of this work is to 1) aid and improve the breadth of Mo paleoproxy interpretations by considering Mo speciation and 2) address outstanding research gaps concerning Mo systematics (cycling, partitioning, sequestration, etc.). The Mo paleoproxy has potential to solve ever complex research questions. By using molecular geochemical recommendations, improved Mo paleoproxy interpretations and reconstruction can be achieved.
Macroevolutionary inference has historically been treated as a two-step process, involving the inference of a tree, and then inference of a macroevolutionary model using that tree. Newer models blend the two steps. These methods make more complete use of fossils than the previous generation of Bayesian phylogenetic models. They also involve many more parameters than prior models, including parameters about which empiricists may have little intuition. In this Element, we set forth a framework for fitting complex, hierarchical models. The authors ultimately fit and use a joint tree and diversification model to estimate a dated phylogeny of the Cincta (Echinodermata), a morphologically distinct group of Cambrian echinoderms that lack the fivefold radial symmetry characteristic of extant members of the phylum. Although the phylogeny of cinctans remains poorly supported in places, this Element shows how models of character change and diversification contribute to understanding patterns of phylogenetic relatedness and testing macroevolutionary hypotheses.
The ideal textbook for non-science majors, this lively and engaging introduction encourages students to ask questions, assess data critically and think like a scientist. Building on the success of previous editions, Dinosaurs has been thoroughly updated to include new discoveries in the field, such as the toothed bird specimens found in China and recent discoveries of dinosaur soft anatomy. Illustrations by leading paleontological illustrator John Sibbick and new, carefully-chosen photographs, clearly show how dinosaurs looked, lived and their role in Earth history. Making science accessible and relevant through clear explanations and extensive illustrations, the text guides students through the dinosaur groups, emphasizing scientific concepts rather than presenting endless facts. Grounded in the common language of modern evolutionary biology - phylogenetic systematics - students learn to think about dinosaurs the way that professional paleontologists do.
Modern videography provides an ever-widening window into subsea echinoderm life with vast potential for new knowledge. Supported by video evidence throughout, this Element begins with time-lapse video made in 1983 on film, using an off-the-shelf camera, flash, and underwater housings. Although quality has now been significantly improved by digital imagery, films from over thirty years ago captured crinoid feeding behavior previously unknown and demonstrated a great potential to learn about many other aspects of their biology. This sequence is followed by several examples of recent digital videography from submersibles of deep-sea crinoids and remotely operated vehicles (ROVs) (stalked and unstalked), as well as close-up video of crinoids in aquaria. These recent studies enabled a new classification of crinoid arm postures, provided detailed views of food particle capture, and revealed a wide range of behaviors in taxa never before seen in life.
Recent advances in statistical approaches called phylogenetic comparative methods (PCMs) have provided paleontologists with a powerful set of analytical tools for investigating evolutionary tempo and mode in fossil lineages. However, attempts to integrate PCMs with fossil data often present workers with practical challenges or unfamiliar literature. This Element presents guides to the theory behind and the application of PCMs with fossil taxa. Based on an empirical dataset of Paleozoic crinoids, example analyses are presented to illustrate common applications of PCMs to fossil data, including investigating patterns of correlated trait evolution and macroevolutionary models of morphological change. The authors emphasize the importance of accounting for sources of uncertainty and discuss how to evaluate model fit and adequacy. Finally, the authors discuss several promising methods for modeling heterogeneous evolutionary dynamics with fossil phylogenies. Integrating phylogeny-based approaches with the fossil record provides a rigorous, quantitative perspective on understanding key patterns in the history of life. |
