"An essential introduction to the paleobiology of animal body size, locomotion, and feeding.Paleobiology is the branch of evolutionary biology involved in the reconstruction of the life histories of extinct organisms. It answers the questions, How do we use fossils to reconstruct the size of prehistoric animals, and How did they move and feed? Drawing on a rich inventory of South American Miocene fossils, Vertebrate Paleobiology: A Form and Function Approach examines different aspects of functional morphology and how they are tested by paleontologists, anatomists, and zoologists. Beginning with a review of various methodologies to interpret fossils, the authors turn to the main concepts important to functional morphology and give examples of each. They conclude by showing how functional morphology enables a dynamic, broadscale reconstruction of the life of prehistoric animals during the South American Miocene.Originally published in Spanish, Vertebrate Paleobiology: A Form and Function Approach provides a broad sweep of recent developments, including theoretical and practical techniques, applied to the study of extinct vertebrates"--

"Despite their fame and reputation, dinosaurs represent only half the story of the Mesozoic Era. In Beast Companions: The Unsung Animals of the Dinosaurs' World, paleontologist John Foster explores the often-overlooked animals that coexisted with them. These ancient species, often equally remarkable as their dinosaur neighbors, can provide valuable insights into the biotic history of our planet. In some cases, these animals reveal just as much, if not more, about the extinct ecosystems of the time as the dinosaurs themselves.By drawing on a wealth of current and past discoveries, Foster embarks on a sweeping journey across 164 million years to visit the beast companions of the dinosaurs. Along the way, he examines fish, insects, the first frogs and salamanders, turtles, snakes and lizards, marine reptiles, crocodiles, pterosaurs, birds, mammals, and other animals of the Mesozoic Era.Beast Companions is a groundbreaking exploration of the story of these contemporaries of the dinosaurs that set the modern world in motion more than 200 million years ago"--

A comprehensive study of the Late Cretaceous, duck-billed dinosaur, featuring insights on its origins, anatomy, and more.Hadrosaurs-also known as duck-billed dinosaurs-are abundant in the fossil record. With their unique complex jaws and teeth perfectly suited to shred and chew plants, they flourished on Earth in remarkable diversity during the Late Cretaceous. So ubiquitous are their remains that we have learned more about dinosaurian paleobiology and paleoecology from hadrosaurs than we have from any other group. In recent years, hadrosaurs have been in the spotlight. Researchers around the world have been studying new specimens and new taxa seeking to expand and clarify our knowledge of these marvelous beasts. This volume presents the results of an international symposium on hadrosaurs, sponsored by the Royal Tyrrell Museum and the Royal Ontario Museum, where scientists and students gathered to share their research and their passion for duck-billed dinosaurs. A uniquely comprehensive treatment of hadrosaurs, the book encompasses not only the well-known hadrosaurids proper, but also Hadrosaouroidea, allowing the former group to be evaluated in a broader perspective. The 36 chapters are divided into six sections-an overview, new insights into hadrosaur origins, hadrosaurid anatomy and variation, biogeography and biostratigraphy, function and growth, and preservation, tracks, and traces-followed by an afterword by Jack Horner."e;Well designed, handsome and fantastically well edited (credit there to Patricia Ralrick), congratulations are deserved to the editors for pulling together a vast amount of content, and doing it well. The book contains a huge quantity of information on these dinosaurs."e; -Darren Naish, co-author of Tetrapod Zoology, Scientific American"e;Hadrosaurs have not had the wide publicity of their flesh-eating cousins, the theropods, but this remarkable dinosaur group offers unique opportunities to explore aspects of palaeobiology such as growth and sexual dimorphism. In a comprehensive collection of papers, all the hadrosaur experts of the world present their latest work, exploring topics as diverse as taxonomy and stratigraphy, locomotion and skin colour."e; -Michael Benton, University of Bristol

"An essential introduction to the age of dinosaurs in Africa. Once Africa was referred to as the ''Lost World of the dinosaur era,'' so poorly known were its ancient flora and fauna. Worse still, many priceless fossil specimens from the Sahara Desert were destroyed during the Second World War. Fortunately, in the twentieth-first century, more researchers are now working in north Africa than ever before and making fascinating discoveries such as the dinosaur Spinosaurus. Based on a decade of study, The Desert Bones brings the world of African dinosaurs fully into the light. Jamale Ijouiher skillfully draws on the latest research and knowledge about paleoecology to paint a compelling and comprehensive portrait of the mid-Cretaceous in North Africa"

A thrilling guide to the Cenozoic mammals of South America, featuring seventy-five life reconstructions of extinct species, plus photos of specimens and sites.South America is home to some of the most distinctive mammals on Earth-giant armadillos, tiny anteaters, the world's largest rodent, and its smallest deer. But the continent once supported a variety of other equally intriguing mammals that have no close living relatives: armored mammals with tail clubs, saber-toothed marsupials, and even a swimming sloth. We know of the existence of these peculiar species thanks to South America's rich fossil record, which provides many glimpses of prehistoric mammals and the ecosystems in which they lived.Organized as a "e;walk through time"e; and featuring species from fifteen important fossil sites, this book is the most extensive and richly illustrated volume devoted exclusively to the Cenozoic mammals of South America. The text is supported by seventy-five life reconstructions of extinct species in their native habitats, as well as photographs of fossil specimens and the sites highlighted in the book. An annotated bibliography is included for those interested in delving into the scientific literature."e;Well-written and easy for the nonspecialist to understand, this is also a most needed updating of this subject, much in the line of classic works such as Simpson's The Beginning of the Age of Mammals in South America and Patterson and Pascual's The Fossil Mammal Fauna of South America."e; -Richard Farina, coauthor Megafauna: Giant Beasts of Pleistocene South America"e;This handsome book, written by a leading expert in South American paleontology, is profusely illustrated with maps, time charts, color photographs of fossils, and exquisite life reconstructions. The book . . . will appeal to any individual, young and old alike, interested in the fossil record, as well as to students and scholars of paleontology who work in other parts of the globe."e; -Choice

Aimed at the general reader, Jurassic West, Second Edition recounts the discovery of many important Late Jurassic dinosaurs made at the famous bone beds of the Morrison Formation.

Told in rich detail and with gorgeous color recreations, this is the story of marine life in the age before the dinosaurs. During the Middle Triassic Period (247-237 million years ago), the mountain of Monte San Giorgio in Switzerland was a tropical lagoon. Today, it is a UNESCO World Heritage Site because it boasts an astonishing fossil record of marine life from that time. Attracted to an incredibly diverse and well-preserved set of fossils, Swiss and Italian paleontologists have been excavating the mountain since 1850.Synthesizing and interpreting over a century of discoveries through a critical twenty-first century lens, paleontologist Olivier Rieppel tells for the first time the complete story of the fish and marine reptiles who made that long-ago lagoon their home. Through careful analysis and vividly rendered recreations, he offers memorable glimpses of not only what Thalattosaurs, Protorosaurs, Ichthyosaurs, Pachypleurosaurs, and other marine life looked like but how they moved and lived in the lagoon. An invaluable resource for specialists and accessible to all, this book is essential to all who are fascinated with ancient marine life.

The Age of Mammals, the Cenozoic Era, has never had its Jurassic Park, but it was an amazing time in earth's history, populated by a wonderful assortment of bizarre animals. This book presents their story, which is part of a larger story of a world emerging from the greenhouse conditions of the Mesozoic.

The forbidding Big Badlands in Western South Dakota contain the richest fossil beds in the world. Even today these rocks continue to yield new specimens brought to light by snowmelt and rain washing away soft rock deposited on a floodplain long ago. The quality and quantity of the fossils are superb: most of the species to be found there are known from hundreds of specimens. The fossils in the White River Group (and similar deposits in the American west) preserve the entire late Eocene through the middle Oligocene, roughly 35-30 million years ago and more than 30 million years after non-avian dinosaurs became extinct. The fossils provide a detailed record of a period of abrupt global cooling and what happened to creatures who lived through it. The book provides a comprehensive reference to the sediments and fossils of the Big Badlands and will complement, enhance, and in some ways replace the classic 1920 volume by Cleophas C. O'Harra. Because the book focuses on a national treasure, it touches on National Park Service management policies that help protect such significant fossils.

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. Felix Perez-Lorente and his colleagues have published extensively on the region, mostly in Spanish-language journals. In this volume, Perez-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 region around Cincinnati, Ohio, is known throughout the world for the abundant and beautiful fossils found in limestones and shales that were deposited as sediments on the sea floor during the Ordovician Period, about 450 million years ago-some 250 million years before the dinosaurs lived. In Ordovician time, the shallow sea that covered much of what is now the North American continent teemed with marine life. The Cincinnati area has yielded some of the world's most abundant and best-preserved fossils of invertebrate animals such as trilobites, bryozoans, brachiopods, molluscs, echinoderms, and graptolites. So famous are the Ordovician fossils and rocks of the Cincinnati region that geologists use the term "e;Cincinnatian"e; for strata of the same age all over North America. This book synthesizes more than 150 years of research on this fossil treasure-trove, describing and illustrating the fossils, the life habits of the animals represented, their communities, and living relatives, as well as the nature of the rock strata in which they are found and the environmental conditions of the ancient sea.

With their spectacularly enlarged canines, sabertooth cats are among the most popular of prehistoric animals, yet it is surprising how little information about them is available for the curious layperson. What's more, there were other sabertooths that were not cats, animals with exotic names like nimravids, barbourofelids, and thylacosmilids. Some were no taller than a domestic cat, others were larger than a lion, and some were as weird as their names suggest. Sabertooths continue to pose questions even for specialists. What did they look like? How did they use their spectacular canine teeth? And why did they finally go extinct? In this visual and intellectual treat of a book, Mauricio Anton tells their story in words and pictures, all scrupulously based on the latest scientific research. The book is a glorious wedding of science and art that celebrates the remarkable diversity of the life of the not-so-distant past.

Istvan Fozy and Istvan Szente provide a comprehensive review of the fossil record of the Carpathian Basin. Fossils of the Carpathian Region describes and illustrates the region's fossils, recounts their history, and tells the stories of key people involved in paleontological research in the area. In addition to covering all the important fossils of this region, special attention is given to rare finds and complete skeletons. The region's fossils range from tiny foraminifera to the Transylvanian dinosaurs and mammals of the Carpathian Basin. The book also gives nonspecialists the opportunity to gain a basic understanding of paleontology. Sidebars present brief biographies of important figures and explain how to collect, prepare, and interpret fossils.

Written for everyone fascinated by the huge beasts that once roamed the earth, this book introduces the giant hornless rhinoceros, Indricotherium. These massive animals inhabited Asia and Eurasia for more than 14 million years, about 37 to 23 million years ago. They had skulls 6 feet long, stood 22 feet high at the shoulder, and were twice as heavy as the largest elephant ever recorded, tipping the scales at 44,100 pounds. Fortunately, the big brutes were vegetarians. Donald R. Prothero tells their story, from their discovery just a century ago to the latest research on how they lived and died.

More than 10,000 years ago spectacularly large mammals roamed the pampas and jungles of South America. This book tells the story of these great beasts during and just after the Pleistocene, the geological epoch marked by the great ice ages. Megafauna describes the history and way of life of these animals, their comings and goings, and what befell them at the beginning of the modern era and the arrival of humans. It places these giants within the context of the other mammals then alive, describing their paleobiology-how they walked; how much they weighed; their diets, behavior, biomechanics; and the interactions among them and with their environment. It also tells the stories of the scientists who contributed to our discovery and knowledge of these transcendent creatures and the environment they inhabited. The episode known as the Great American Biotic Interchange, perhaps the most important of all natural history "e;experiments,"e; is also an important theme of the book, tracing the biotic events of both North and South America that led to the fauna and the ecosystems discussed in this book.

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.

Have you ever wondered what left behind those prints and tracks on the seashore, or what made those marks or dug those holes in the dunes? Life Traces of the Georgia Coast is an up-close look at these traces of life and the animals and plants that made them. It tells about how the tracemakers lived and how they interacted with their environments. This is a book about ichnology (the study of such traces) and a wonderful way to learn about the behavior of organisms, living and long extinct. Life Traces presents an overview of the traces left by modern animals and plants in this biologically rich region; shows how life traces relate to the environments, natural history, and behaviors of their tracemakers; and applies that knowledge toward a better understanding of the fossilized traces that ancient life left in the geologic record. Augmented by illustrations of traces made by both ancient and modern organisms, the book shows how ancient trace fossils directly relate to modern traces and tracemakers, among them, insects, grasses, crabs, shorebirds, alligators, and sea turtles. The result is an aesthetically appealing and scientifically grounded book that will serve as source both for scientists and for anyone interested in the natural history of the Georgia coast.

A fascinating, comprehensive, accessible account of conodont fossilsone of paleontology's greatest mysteries: ';Deserves to be widely read and enjoyed' (Priscum). Stephen Jay Gould borrowed from Winston Churchill when he described the eel-like conodont animal as a riddle wrapped in a mystery inside an enigma. The search for its identity confounded scientists for more than a century. Some thought it a slug, others a fish, a worm, a plant, even a primitive ancestor of ourselves. As the list of possibilities grew, an answer to the riddle never seemed any nearer. Would the animal that left behind the miniscule fossils known as conodonts ever be identified? Three times the creature was found, but each was quite different from the others. Were any of them really the one? Simon J. Knell takes the reader on a journey through 150 years of scientific thinking, imagining, and arguing. Slowly the animal begins to reveal traces of itself: its lifestyle, its remarkable evolution, its witnessing of great catastrophes, its movements over the surface of the planet, and finally its anatomy. Today the conodont animal remains perhaps the most disputed creature in the zoological world.

An entertaining and informative guide to an astonishing and little-known world

How can the tracks of dinosaurs best be interpreted and used to reconstruct them? In many Mesozoic sedimentary rock formations, fossilized footprints of bipedal, three-toed (tridactyl) dinosaurs are preserved in huge numbers, often with few or no skeletons. Such tracks sometimes provide the only clues to the former presence of dinosaurs, but their interpretation can be challenging: How different in size and shape can footprints be and yet have been made by the same kind of dinosaur? How similar can they be and yet have been made by different kinds of dinosaurs? To what extent can tridactyl dinosaur footprints serve as proxies for the biodiversity of their makers?Profusely illustrated and meticulously researched, Noah's Ravens quantitatively explores a variety of approaches to interpreting the tracks, carefully examining within-species and across-species variability in foot and footprint shape in nonavian dinosaurs and their close living relatives. The results help decipher one of the world's most important assemblages of fossil dinosaur tracks, found in sedimentary rocks deposited in ancient rift valleys of eastern North America. Those often beautifully preserved tracks were among the first studied by paleontologists, and they were initially interpreted as having been made by big birds--one of which was jokingly identified as Noah's legendary raven.

With its massive head, enormous jaws, and formidable teeth, Tyrannosaurus rex has long been the young person's favorite creepy carnivore in the Mesozoic zoo. This collection explores such questions as why T rexhad such small forelimbs; how the dinosaur moved; and, what bone pathologies tell us about life in the Cretaceous.

Showcases research of broad botanical and paleontological interest from the world's experts on Mesozoic plant life. This title covers various aspects of plant group - ranging from horsetails to ginkgophytes, from cycads to conifers - and relates them to key innovations in structure, phylogenetic relationships, Mesozoic vegetation.
