Receptaculitids are extinct high-level fossils that provide a window into the history of life. After the discovery and analysis of a deposit of phosphatized receptaculitids on the Baltic Sea island of Oland, the authors conclude that receptaculitids possess an attribute not found in any other group of organisms, living or fossil."
The ability for people to connect, learn, and communicate about science has been enhanced through the Internet, specifically through social media platforms. Facebook and Twitter are well-studied, while Instagram is understudied. This Element provides insight into using Instagram as a science education platform by pioneering a set of calculated metrics, using a paleontology-focused account as a case study. Framed by the theory of affinity spaces, the authors conducted year-long analyses of 455 posts and 139 stories that were created as part of an informal science learning project. They found that team activity updates and posts outside of their other categories perform better than their defined categories. For Instagram stories, the data show that fewer slides per story hold viewers' attention longer, and stories using the poll tool garnered the most interaction. This Element provides a baseline to assess the success of Instagram content for science communicators and natural science institutions.
A Late Ordovician silicified brachiopod fauna from the White Mountain area, west-central Alaska is described and interpreted in a palaeoecological and biogeographical context. This area is situated within the Nixon Fork Subterrane of the Farewell Terrane, which origin and timing of final docking with Laurentia has been much debated. The current study adds new faunal data to the debate with nearly 100 species described, of these at least nine are new. The fauna is predominantly a deep-water autochthonous fauna that was mixed with an allochthonous fauna as a result of down-slope movement of turbidity currents. Biogeographically this study demonstrates close faunal affinities with Siberia.
That humans originated from Africa is well-known. However, this is widely regarded as a chance outcome, dependant simply on where our common ancestor shared the land with where the great apes lived. This volume builds on from the 'Out of Africa' theory, and takes the view that it is only in Africa that the evolutionary transitions from a forest-inhabiting frugivore to savanna-dwelling meat-eater could have occurred. This book argues that the ecological circumstances that shaped these transitions are exclusive to Africa. It describes distinctive features of the ecology of Africa, with emphasis on savanna grasslands, and relates them to the evolutionary transitions linking early ape-men to modern humans. It shows how physical features of the continent, especially those derived from plate tectonics, set the foundations. This volume adequately conveys that we are here because of the distinctive features of the ecology of Africa.
The names given to the variety of man-like fossils known to scientists should reflect no more than scientific views of the nature of human evolution. However, often in the past these names have also reflected confusion regarding the basic principles of scientific nomenclature; and the matter has been further complicated by the many new finds of recent decades. It is the unique purpose of this book to clarify the present state of knowledge regarding the main lines of human evolution by expressing what is known (and what is surmised) about them in appropriate taxonomic language. The papers in this volume were prepared by the world's leading authorities on the subject, and were revised in the light of discussions at a remarkable conference held in Austria in 1962 under the auspices of the Wenner-Gren Foundation. The authors review first the meaning of taxonomic statements as such, and then consider the substance of 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 behavior changes and selection pressures in evolutionary sequences. Ample illustrations, bibliographies and an index enhance the permanent reference value of the book, which will undoubtedly prove to be among the fundamental paleoanthropological works of our time.
In 1898, a 19-year-old girl marched into the Natural History Museum and demanded a job. At the time, no women were employed there as scientists, but for the determined Dorothea Bate this was the first step in an extraordinary career as a pioneering explorer and fossil-hunter and the beginning of an association with the Museum that was to last for more than 50 years. As a young woman in the early 1900s she explored the islands of Cyprus, Crete and the little known Majorca and Menorca, braving parental opposition and considerable physical hardship and danger. In remote mountain caves and sea-battered cliffs, she discovered, against enormous odds, the fossil evidence of unique species of extinct fauna, previously unknown to science, including dwarf elephants and hippos, giant dormice and a strange small goat-like antelope. Thirty years later in Bethlehem, she excavated against a backdrop of violence and under the shadow of war. By the end of her life Dorothea had earned an international reputation as an expert in her field. 'Discovering Dorothea' captures the indomitable spirit of a woman who, against social pressure and in the face of physical hardship, devoted her life to discovery and deepened our knowledge of the natural world.
This work is a detailed study of people and plants in Little Dixie, a seven-county region of central Missouri. Based on three summers of field research, Professor Nolan combines ethnoscience with folklore to document what and why people know about wild plants in this little-known section of the American Midwest. The book is organized around the cognitive and behavioral differences between local experts and 'novices' who gather wild plant foods and medicines regularly throughout the seasons in Little Dixie. Ethnobotanical knowledge is described as an ongoing interaction between ecology and cognition, under constant modification by shifting cultural beliefs about edibility, efficacy, and sensory appeal. As consumable resources and symbols of belonging, wild plants are detailed with ethnographic context and vivid pen-and-ink sketches. Wild Harvest in the Heartland will appeal to a broad audience of anthropologists, ethnobotanists, folklorists, and ecologists, and will provide a welcome resource for naturalists, conservationists, and outdoor enthusiasts.
Late Quaternary Environmental Change addresses the interaction between human agency and other environmental factors in the landscapes, particularly of the temperate zone. Taking an ecological approach, the authors cover the last 20,000 years during which the climate has shifted from arctic severity to the conditions of the present interglacial environment.
Placing evolutionary events in the context of geological time is a fundamental goal in paleobiology and macroevolution. In this Element we describe the tripartite model used for Bayesian estimation of time calibrated phylogenetic trees. The model can be readily separated into its component models: the substitution model, the clock model and the tree model. We provide an overview of the most widely used models for each component and highlight the advantages of implementing the tripartite model within a Bayesian framework.
This book is a reprint of the fourth edition, published in 1989, of the Textbook of Pollen Analysis and is unique in its approach as it discusses both the practical and theoretical aspects of palynology. It uses palynological techniques as tools for solving problems in quaternary geology, ecology and archeology. This edition of this standard reference has the same objectives as the earlier ones but the objectives have been widened, particularly the archaeological. There are over 130 illustrations and the identification keys have been thoroughly revised and are now illustrated. "Will certainly benefit all in understanding the principles of pollen analysis. All students, palynologists and libraries should have it as a text book for reference." Marine Geology "Classic and much-used text book ... will remain an indispensable book for those interested in paleoecology and practicing pollen analysis." The New Phycologist "Unsurpassed in its restriction to basic principles, breadth of coverage, clarity of expression and emphasis on ecology." Review of Paleobotany and Palynology
Evolution is the single unifying principle of biology and core to everything in the life sciences. More than a century of work by scientists from across the biological spectrum has produced a detailed history of life across the phyla and explained the mechanisms by which new species form. This textbook covers both this history and the mechanisms of speciation; it also aims to provide students with the background needed to read the research literature on evolution. Students will therefore learn about cladistics, molecular phylogenies, the molecular-genetical basis of evolutionary change including the important role of protein networks, symbionts and holobionts, together with the core principles of developmental biology. The book also includes introductory appendices that provide background knowledge on, for example, the diversity of life today, fossils, the geology of Earth and the history of evolutionary thought. Key Features Summarizes the origins of life and the evolution of the eukaryotic cell and of Urbilateria, the last common ancestor of invertebrates and vertebrates. Reviews the history of life across the phyla based on the fossil record and computational phylogenetics. Explains evo-devo and the generation of anatomical novelties. Illustrates the roles of small populations, genetic drift, mutation and selection in speciation. Documents human evolution using the fossil record and evidence of dispersal across the world leading to the emergence of modern humans.

The Pliocene-Pleistocene Crags of East Anglia are an incredibly rich source of fossil shells, many belonging to extant Boreal and Mediterranean genera. Dominated by marine gastropods and bivalves, the deposits also contain evidence of terrestrial and non-marine gastropods and bivalves, brachiopods, and extensive epifauna including bryozoans. Published between 1848 and 1879 in four volumes, the latter two being supplements with further descriptions and geological notes, this monograph by Searles Valentine Wood (1798-1880) covers more than 650 species and varieties of fossil mollusc. For each species Wood gives a synonymy, diagnosis (in Latin), full description, dimensions, occurrence and remarks. The supplements also provide a breakdown of the species and their current distribution. The detailed plates were prepared by the conchologist George Brettingham Sowerby and his namesake son. Volume 1 (1848) covers gastropods and scaphopods, illustrated in 21 plates.

This volume explores the diverse ways in which the evolution of human behaviour can be investigated, and confronts the most challenging aspects of the subject.
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.
'Truth and courage are what memoirs need and this one has them both in spades … The unforgotten boy: that is what makes this a book a revelation' ADAM NICOLSON ‘Wonderful, absolutely beguiling … I learnt a lot and really loved it’ RICHARD HOLMES ‘Gloriously evocative’ DAILY MAIL What makes a scientist? Charming, funny and wise, in this memoir Richard Fortey shows how restless curiosity about the natural world led him to become a leading scientist and writer, with adventures and misadventures along the way. From a garden shed laboratory where he manufactured the greatest stink in the world to a tent high in the Arctic in pursuit of fossils, this is a story of obsession and love of nature, flavoured with the peculiarities and restrictions of post-war Britain. Fortey tells the story of following his father down riverbanks to fish for trout, and also of his father's shocking death. He unfolds his early passions – fungi, ammonite hunting and eyeing up bird's eggs. He evokes with warmth and wit how the natural world started out as his playground and refuge, then became his life's work. Much more than a story about science alone, this memoir gives an unforgettable portrait of a young, curious mind, and shows how luck and enthusiasm can create a special life.
Marine biogeography, the study of the spatial distribution of organisms in the world's oceans, is one of the most fascinating branches of oceanography. This book continues the pioneering research into the distributions of molluscan faunas, first studied by biologists over 160 years ago. It illustrates 1778 species of gastropods in full color, many of which are extremely rare and poorly known endemic species that are illustrated for the first time outside of their original descriptions. The spatial arrangements of malacofaunas shown in this book can be considered proxies for worldwide oceanic conditions and used as tools for determining patterns of global climate change. The book's documentation of evolutionary "hot spots" and geographically restricted endemic faunas can also be used as a base line for future studies on patterns of environmental deterioration and extinction in the marine biosphere. Documenting the evolution of the amazingly rich worldwide gastropod fauna, this book will appeal to physical and chemical oceanographers, systematic and evolutionary biologists, historical geologists, paleontologists, climatologists, geomorphologists, and physical geographers. The authors incorporate aspects of all of these disciplines into a new classification system for the nomenclature of biogeographical spatial units found in tropical, subtropical, and warm temperate seas.
This book provides a wealth of geomathematical case history studies performed by the author during his career at the Ministry of Natural Resources Canada, Geological Survey of Canada (NRCan-GSC). Several of the techniques newly developed by the author and colleagues that are described in this book have become widely adopted, not only for further research by geomathematical colleagues, but by government organizations and industry worldwide. These include Weights-of-Evidence modelling, mineral resource estimation technology, trend surface analysis, automatic stratigraphic correlation and nonlinear geochemical exploration methods. The author has developed maximum likelihood methodology and spline-fitting techniques for the construction of the international numerical geologic timescale. He has introduced the application of new theory of fractals and multi fractals in the geostatistical evaluation of regional mineral resources and ore reserves and to study the spatial distribution of metals in rocks. The book also contains sections deemed important by the author but that have not been widely adopted because they require further research. These include the geometry of preferred orientations of contours and edge effects on maps, time series analysis of Quaternary retreating ice sheet related sedimentary data, estimation of first and last appearances of fossil taxa from frequency distributions of their observed first and last occurrences, tectonic reactivation along pre-existing schistosity planes in fold belts, use of the grouped jackknife method for bias reduction in geometrical extrapolations and new applications of the theory of permanent, volume-independent frequency distributions.
This textbook introduces research on dinosaurs by describing the science behind how we know what we know about dinosaurs. A wide range of topics is covered, from fossils and taphonomy to dinosaur physiology, evolution, and extinction. In addition, sedimentology, paleo-tectonics, and non-dinosaurian Mesozoic life are discussed. There is a special opportunity to capitalize on the enthusiasm for dinosaurs that students bring to classrooms to foster a deeper engagement in all sciences. Students are encouraged to synthesize information, employ critical thinking, construct hypotheses, devise methods to test these hypotheses, and come to new defensible conclusions, just as paleontologists do. Key Features Clear and easy to read dinosaur text with well-defined terminology Over 600 images and diagrams to illustrate concepts and aid learning Reading objectives for each chapter section to guide conceptual learning and encourage active reading Companion website (teachingdinosaurs.com) that includes supporting materials such as in-class activities, question banks, lists of suggested specimens, and more to encourage student participation and active learning Ending each chapter with a specific "What We Don't Know" section to encourage student curiosity Related Titles Singer, R.

What would it be like to experience the ancient landscapes of the past as we experience the reality of nature today? To actually visit the Jurassic or Cambrian worlds, to wander among their spectacular flora and fauna, to witness their continental shifts? In Otherlands, the multi-talented palaeontologist Thomas Halliday gives us a breath-taking up close encounter with worlds that are normally unimaginably distant. Journeying backwards in time from the most recent Ice Age to the dawn of complex life itself, and across all seven continents, Halliday immerses us in sixteen lost ecosystems, each one rendered with a novelist's eye for detail and drama. Every description - whether the colour of a beetle's shell, the shambling rhythm of pterosaurs in flight or the lingering smell of sulphur in the air - is grounded in fact. We visit the birthplace of humanity on the shores of the great lake Lonyumun, in Pliocene-era Kenya; in the Miocene, we hear the crashing of the highest waterfall the world has ever known as it fills the evaporated Mediterranean Sea; we encounter forests of giant fungus nine metres tall in Devonian-era Scotland; and we gaze at the light of a full and enormous moon in the Ediacaran sky, when life hasn't yet reached land. To read Otherlands is to time travel, to see the last 550 million years not as an endless expanse of unfathomable time, but as a series of worlds, simultaneously fantastical and familiar.
The plant fossil record provides evidence that the genus Metasequoia was widely distributed and experienced a wide range of climatic and environmental conditions throughout the Northern Hemisphere from the early Late Cretaceous to the Plio-Pleistocene. Today the genus is limited to one species with approximately 5,000 mature individuals growing in the Xiahoe Valley in southeastern China. This book is a distillation of the collective efforts and results of the worlda (TM)s Metasequoia specialists and enthusiasts. It is the most up-to-date and comprehensive reference source for the genus and the authors have sought to incorporate obscure, hard-to-get and non-English reference sources. The book reviews what is known about the biology, ecology and physiology of fossil and living Metasequoia, current research directions and problems that remain unresolved. This book presents a definitive overview of fossil and living Metasequoia and was written by sixteen of the worlda (TM)s experts on this important genus. Given the reality of increasing human pressure and the inevitability of global change, efforts to conserve this ancient genus are underway. This book will be of interest to botanists, geologists, paleobotanists, biogeographers, foresters, ecologists, paleoecologists, ecophysiologists, geochemists, climate modelers, geneticists, naturalists, science historians, and gardeners and will be useful as a supplemental text for advanced undergraduate and graduate level courses in paleoecology.
In this deep examination of functional morphology, a renowned paleoanthropologist offers a new way to investigate human evolution through the fossil record. It is common for two functional anatomists to examine the exact same fossil material, yet argue over its evolutionary significance. How can this be? Traditionally, paleoanthropology has interpreted hominin fossil morphology by first considering the ecological challenges hominins faced, then drawing adaptive inferences based on the idea that skeletal morphology is largely a reflection of paleoecology. In Functional Inference in Paleoanthropology, innovative paleoanthropologist David J. Daegling suggests that researchers can resolve dichotomous interpretations of the fossil record by instead focusing on the biology and development of the bones themselves-such as measurable responses to deformations, stresses, and damage. Critically exploring how scientists probe and interpret fossil morphology for behavioral and adaptive inferences, Daegling makes the case that an intelligible science of functional morphology in the fossil record is impossible without the inclusion of this mechanobiological perspective. Drawing on historical examples from long-standing debates on the emergence of bipedality and the dietary shifts that facilitated the emergence of the hominin clade, Daegling traces the disjunctions between theoretical principles of comparative morphology and methodological practice in the paleontological context of human evolution. Sharing rich findings from recent decades of research in skeletal biomechanics, Functional Inference in Paleoanthropology examines how bone adapts over the lifespan, what environmental factors influence its quality, and how developmental constraints limit the skeleton's adaptive potential over evolutionary time. |
