On the Edge of a New Understanding
The Clovis culture remains the benchmark for chronological, technological, and adaptive comparisons in research on peopling of the Americas.
In Clovis: On the Edge of a New Understanding, volume editors Ashley Smallwood and Thomas Jennings bring together the work of many researchers actively studying the Clovis complex. The contributing authors presented earlier versions of these chapters at the symposium for which this book is titled—Clovis: Current Perspectives on Chronology, Technology, and Adaptations—held at the 2011 Society for American Archaeology meetings in Sacramento, California. In seventeen chapters, the researchers provide their current perspectives of the Clovis archaeological record as they address the question: What is and what is not Clovis?

What do we know about dinosaurs, and how do we know it? How did dinosaurs grow, move, eat, and reproduce? Were they warm-blooded or cold-blooded? How intelligent were they? How are the various groups of dinosaurs related to each other, and to other kinds of living and extinct vertebrates? What can the study of dinosaurs tell us about the process of evolution? And why did typical dinosaurs become extinct? All of these questions, and more, are addressed in the new, expanded, second edition of The Complete Dinosaur. Written by many of the world's leading experts on the "fearfully great" reptiles, the book’s 45 chapters cover what we have learned about dinosaurs, from the earliest discoveries of dinosaurs to the most recent controversies. Where scientific contention exists, the editors have let the experts agree to disagree. Copiously illustrated and accessible to all readers from the enthusiastic amateur to the most learned professional paleontologist, The Complete Dinosaur is a feast for serious dinosaur lovers everywhere.
During the Early Cretaceous, lakes, meandering streams, and flood plains covered the region where the current foothills of Rioja now exist. Today the area is known for its wine and for the dozens of sites where footprints and trackways of dinosaurs, amphibians, and even pterosaurs can be seen. The dinosaurs that lived here 120 million years ago left their footsteps imprinted in the mud and moist soil. Now fossilized in rock, they have turned Rioja into one of the most valuable dinosaur footprint sites in all of Europe. Félix Pérez-Lorente and his colleagues have published extensively on the region, mostly in Spanish-language journals. In this volume, Pérez-Lorente provides an up-to-date synthesis of that research in English. He offers detailed descriptions of the sites, footprints, and trackways, and explains what these prints and tracks can tell us about the animals who made them.
The Next Steps
The latest advances in dinosaur ichnology are showcased in this comprehensive and timely volume, in which leading researchers and research groups cover the most essential topics in the study of dinosaur tracks. Some assess and demonstrate state-of-the-art approaches and techniques, such as experimental ichnology, photogrammetry, biplanar X-rays, and a numerical scale for quantifying the quality of track preservation. The high diversity of these up-to-date studies underlines that dinosaur ichnological research is a vibrant field, that important discoveries are continuously made, and that new methods are being developed, applied, and refined. This indispensable volume unequivocally demonstrates that ichnology has an important contribution to make toward a better understanding of dinosaur paleobiology. Tracks and trackways are one of the best sources of evidence to understand and reconstruct the daily life of dinosaurs. They are windows on past lives, dynamic structures produced by living, breathing, moving animals now long extinct, and they are every bit as exciting and captivating as the skeletons of their makers.
This overview of dinosaur discoveries in Mexico synthesizes current information about the geography and environment of the region during the Mesozoic when it was the western margin of the ancient continent of Pangea. The book summarizes research on various groups, including turtles, lepidosauromorphs, plesiosaurs, crocodyliforms, pterosaurs, and last but not least, dinosaurs. In addition, chapters focus on trackways and other trace fossils and on K/P boundary (the Chicxulub crater, beneath the Gulf of Mexico, has been hypothesized as the site of the boloid impact that killed off the dinosaurs). Dinosaurs and Other Reptiles from the Mesozoic of Mexico is an up-to-date, informative volume on an area that has not been comprehensively described until now.
Dinosaurs of Utah is an ambitious book bridging the gap between the voluminous technical literature on Utah’s Mesozoic era and the numerous publications that describe dinosaurs at the elementary level. “Utah” dinosaurs are presented here as part of the Mesozoic terrestrial ecosystems that evolved in the Colorado Plateau region and are discussed in the context of the changing landscapes, environments, and biota recorded in the geological record.
More than one hundred of author Frank DeCourten’s meticulous line drawings illustrate fossil remains and various features of dinosaur anatomy, as do five stunning paintings by Carel Brest van Kempen. More than forty color landscape photographs by John Telford and Frank DeCourten show modern geologic contexts in most parts of the state and emphasize the dynamic nature of the region’s geologic history. There is also a series of detailed maps, including several new to this edition, that show the tremendous topographical shifts that occurred within the Mesozoic era from the early Triassic to the late Cretaceous periods, a span of over 175 million years.
This second edition of Dinosaurs of Utah enlivens our understanding of these amazing vanished creatures by explaining them and their world to us. It moves beyond the often superficial representations that have been so prevalent and more accurately portrays the variety of dinosaurs that once roamed the region now known as Utah.
In 1961, while mapping rock exposures along the Colville River in Alaska, an oil company geologist would unknowingly find the evidence for a startling discovery. Long before the North Slope of Alaska was being exploited for its petroleum resources it was a place where dinosaurs roamed. Dinosaurs under the Aurora immerses readers in the challenges, stark beauty, and hard-earned rewards of conducting paleontological field work in the Arctic. Roland A. Gangloff recounts the significant discoveries of field and museum research on Arctic dinosaurs, most notably of the last 25 years when the remarkable record of dinosaurs from Alaska was compiled. This research has changed the way we think about dinosaurs and their world. Examining long-standing controversies, such as the end-Cretaceous extinction of dinosaurs and whether dinosaurs were residents or just seasonal visitors to polar latitudes, Gangloff takes readers on a delightful and instructive journey into the world of paleontology as it is conducted in the land under the aurora.
A Natural History
The Dodo and the Solitaire is the most comprehensive book to date about these two famously extinct birds. It contains all the known contemporary accounts and illustrations of the dodo and solitaire, covering their history after extinction and discussing their ecology, classification, phylogenetic placement, and evolution. Both birds were large and flightless and lived on inhabited islands some 500 miles east of Madagascar. The first recorded descriptions of the dodo were provided by Dutch sailors who first encountered them in 1598—within 100 years, the dodo was extinct. So quickly did the bird disappear that there is insufficient evidence to form an entirely accurate picture of its appearance and ecology, and the absence has led to much speculation. The story of the dodo, like that of the solitaire, has been pieced together from fragments, both literary and physical, that have been carefully compiled and examined in this extraordinary volume.
Dinosaurs and the Science Wars
"... are dinosaurs social constructs? Do we really know anything about dinosaurs? Might not all of our beliefs about dinosaurs merely be figments of the paleontological imagination? A few years ago such questions would have seemed preposterous, even nonsensical. Now they must have a serious answer."
At stake in the "Science Wars" that have raged in academe and in the media is nothing less than the standing of science in our culture. One side argues that science is a "social construct," that it does not discover facts about the world, but rather constructs artifacts disguised as objective truths. This view threatens the authority of science and rejects science's claims to objectivity, rationality, and disinterested inquiry. Drawing Out Leviathan examines this argument in the light of some major debates about dinosaurs: the case of the wrong-headed dinosaur, the dinosaur "heresies" of the 1970s, and the debate over the extinction of dinosaurs.
Keith Parsons claims that these debates, though lively and sometimes rancorous, show that evidence and logic, not arbitrary "rules of the game," remained vitally important, even when the debates were at their nastiest. They show science to be a complex set of activities, pervaded by social influences, and not easily reducible to any stereotype. Parsons acknowledges that there are lessons to be learned by scientists from their would-be adversaries, and the book concludes with some recommendations for ending the Science Wars.
The Rock Record of Biological Development
How can we bring together the study of genes, embryos and fossils? Embryos in Deep Time is a critical synthesis of the study of individual development in fossils. It brings together an up-to-date review of concepts from comparative anatomy, ecology and developmental genetics, and examples of different kinds of animals from diverse geological epochs and geographic areas.
Can fossil embryos demonstrate evolutionary changes in reproductive modes? How have changes in ocean chemistry in the past affected the development of marine organisms? What can the microstructure of fossil bone and teeth reveal about maturation time, longevity and changes in growth phases? This book addresses these and other issues and documents with numerous examples and illustrations how fossils provide evidence not only of adult anatomy but also of the life history of individuals at different growth stages. The central topic of Biology today—the transformations occurring during the life of an organism and the mechanisms behind them—is addressed in an integrative manner for extinct animals.
