Sauropodomorpha Huene 1932 is one of the most successful groups of dinosaurs, including the most abundant and diverse herbivorous forms with a worldwide record, extending from the late Triassic to the late Cretaceous. Sauropodomorphs comprise a diverse assemblage of early forms (traditionally called “prosauropods”) and the well-established clade Sauropoda Marsh 1878. Early sauropodomorphs were small to medium sized forms, with long necks and reduced skulls, mostly bipeds and omnivores and were abundant in continental environments in the Late Triassic and Early Jurassic. With more than 150 valid species and a worldwide distribution, Sauropoda includes the dominant herbivorous dinosaurs, from the Middle Jurassic to the Late Cretaceous. Its unique body plan, characterized by gigantic size, graviportal locomotion, long necks and tails, and reduced skulls, made this group an undisputed icon in popular culture since the 19th century. In South America, the sauropodomorph record is particularly rich and abundant, and many species have shed light to understand important milestones in the evolutionary history of this group of dinosaurs. The origin of Sauropodomorpha, the transition to Sauropoda, and the diversification of its most successful evolutionary lineages are largely exemplified by the South American fossil record. In this contribution, we synthetize the diversity of sauropodomorphs from South America, including data on their geographic and stratigraphic provenance, phylogenetics, paleobiology, taphonomy and behaviour, underscoring their significance within the context of sauropodomorph evolution.

New research on the giants of the Age of Dinosaurs.

The remarkable dinosaur faunas of South America

Sauropods, those huge plant-eating dinosaurs, possessed bodies that seem to defy every natural law. What were these creatures like as living animals and how could they reach such uniquely gigantic sizes? A dedicated group of researchers in Germany in disciplines ranging from engineering and materials science to animal nutrition and paleontology went in search of the answers to these questions. Biology of the Sauropod Dinosaurs reports on the latest results from this seemingly disparate group of research fields and integrates them into a coherent theory regarding sauropod gigantism. Covering nutrition, physiology, growth, and skeletal structure and body plans, this volume presents the most up-to-date knowledge about the biology of these enormous dinosaurs.

“Bonnan combines wit and passion with the sensibilities of a talented instructor in this encyclopedic tour of the vertebrate skeleton.” —Publishers Weekly What can we learn about the evolution of jaws from a pair of scissors? How does the flight of a tennis ball help explain how fish overcome drag? What do a spacesuit and a chicken egg have in common? Highlighting the fascinating twists and turns of evolution across more than 540 million years, paleobiologist Matthew Bonnan uses everyday objects to explain the emergence and adaptation of the vertebrate skeleton. What can camera lenses tell us about the eyes of marine reptiles? How does understanding what prevents a coffee mug from spilling help us understand the posture of dinosaurs? The answers to these and other intriguing questions illustrate how scientists have pieced together the history of vertebrates from their bare bones. With its engaging and informative text, plus more than 200 illustrative diagrams created by the author, The Bare Bones is an unconventional and reader-friendly introduction to the skeleton as an evolving machine. “No bones about it, a text like The Bare Bones was sorely needed in the popular literature of vertebrate paleontology. Matthew Bonnan’s tome on the evolution, form, and function of the vertebrate skeleton may seem daunting in size, but it is written in an enjoyable and readable fashion that will absolutely delight all sorts of readers from expert to soon-to-be-expert.” —Palaeontologia Electronica “A remarkably fun book to read . . . his conversational style and wit make this an unintimidating yet highly informative book that would work wonderfully in college courses.” —The Quarterly Review of Biology

An illustrated record book of sauropod facts and figures—the hugest, the oldest, the most intelligent, and more The sauropod dinosaurs roamed the planet for millions of years, with creatures ranging from the smallest of the sauropods, Magyarosaurus, to the huge Argentinosaurus. This illustrated book of records is an essential compendium of sauropod facts and figures—from the biggest and the oldest to the smallest and the rarest. It covers every known species and features more than 2,000 diagrams and technical drawings along with hundreds of full-color reconstructions of specimens. The book is divided into sections that put numerous amazing sauropod facts at your fingertips. "Comparing Species" is organized by taxonomic group and gives comparisons of the size of species, how long ago they lived, and when they were discovered. "Mesozoic Calendar" includes page spreads showing the positions of the continents at different geological time periods and reconstructions of creatures from each period. "Prehistoric Puzzles" compares bones and teeth while "Sauropod Life" presents user-friendly graphics to answer questions like what did they eat and which was the most intelligent. There are sections that chart sauropod distribution on the contemporary world map, provide illustrated listings of footprints, compile the physical specifications of all known sauropods, and more. The essential illustrated record book for anyone interested in dinosaurs Features a wealth of comparative records Includes more than 2,000 diagrams and technical drawings and hundreds of full-color reconstructions Covers all known sauropodomorph species Provides listings of footprints, biometric specifications, and scholarly and popular references

Sauropod dinosaurs were the largest animals ever to walk the earth, and they represent a substantial portion of vertebrate biomass and biodiversity during the Mesozoic Era. The story of sauropod evolution is told in an extensive fossil record of skeletons and footprints that span the globe and 150 million years of earth history. This generously illustrated volume is the first comprehensive scientific summary of sauropod evolution and paleobiology. The contributors explore sauropod anatomy, detail its variations, and question the myth that life at large size led to evolutionary stagnation and eventual replacement by more "advanced" herbivorous dinosaurs. Chapters address topics such as the evolutionary history and diversity of sauropods; methods for creating three-dimensional reconstructions of their skeletons; questions of sauropod herbivory, tracks, gigantism, locomotion, reproduction, growth rates, and more. This book, together with the recent surge in sauropod discoveries around the world and taxonomic revisions of fragmentary genera, will shed new light on "nature's greatest extravagances."

This book presents a detailed examination of the current state of knowledge in the field of paleoneurology in the main amniote groups (reptiles, birds and mammals), and advances resulting from new non-invasive technologies. The study of fossil endocasts is an area of considerable current interest, and has long been central to our understanding of the evolution of the brain, development of senses and behavioral adaptations in diverse vertebrate groups and across vertebrates as a whole. Recent advances in non-invasive imaging have significantly increased the number of fossil taxa for which brain morphology is known, and it may now be possible to quantitatively analyze the relative size of brain regions. Providing a general overview of current perspectives and problems in evolutionary neuroanatomy, this book is intended for a wide range of readers, including undergraduate and graduate students, teachers, and anyone with a special interest in paleoneurology. It is also useful as supplementary reading for courses in digital anatomy, vertebrate comparative anatomy, computed morphometrics, paleontology, neurology and radiology as well as evolution programs

This book summarizes the most relevant published paleontological information, supplemented by our own original work, on the record of Mesozoic mammals’ evolution, their close ancestors and their immediate descendants. Mammals evolved in a systematically diverse world, amidst a dynamic geography that is at the root of the 6,500 species living today. Fossils of Mesozoic mammals, while rare and often incomplete, are key to understanding how mammals have evolved over more than 200 million years. Mesozoic mammals and their close relatives occur in a few dozen localities from Argentina, Brazil, Chile, Bolivia, and Peru spanning from the Mid- Triassic to the Late Cretaceous, with some lineages surviving the cataclysmic end of the Cretaceous period, into the Cenozoic of Argentina. There are roughly 25 recognized mammalian species distributed in several distinctive lineages, including australosphenidans, multituberculates, gondwanatherians, eutriconodonts, amphilestids and dryolestoids, among others. With its focus on diversity, systematics, phylogeny, and their impact on the evolution of mammals, there is no similar book currently available.

Comprehensive in detail and worldwide in scope, Chirotheres is the definitive compendium of what is known about the five-toed footprints of Triassic archosaurs, ancestors of the crocodiles. Sandstone slabs with extensive trackways have been known for almost two centuries and are highlights in museum exhibits around the globe. These trackways provide direct insight into the locomotion and behavior of the fascinating reptiles that made these tracks, and, together with known skeletons, they allow a richer reconstruction of chirothere lifestyle than is possible from bones alone. Written by expert researchers in the fields of vertebrate ichnology, vertebrate paleontology, and scientific illustration, Chirotheres explores the various facets ofchirothere research including the history of their study, footprint formation and preservation, the bone record, the environment and lifestyle of chirotheres, and finally, their disappearance at the end of the Triassic. Chirotheres also featuresa global compendium of track collections with chirothere material, including specimen numbers, detailed phylogenetic definitions of track makers, and extensive measurements from key chirothere tracks and trackways. It represents an invaluable resource of anyone interested in these ancient animals.
