Book Description
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.

Book Description
This book takes a non-technical approach in covering the evolution of South American mammalian fauna throughout geological history, and discusses how South America has changed due to mammalian invasions. Unlike other works on the subject, this book attempts to answer several crucial questions that often go unmentioned together in one cohesive monograph. What was the fauna like before the American interchange? What were the origins of the now-extinct groups when northern species arrived and out-competed them? How did the modern mammalian fauna come into being with such disparate animal groups? This information is given from a historical perspective throughout the book's 15 chapters, and is presented in an easily graspable fashion by mostly avoiding technical language. The book is written for academics, scientists and scholars engaged in paleontology, zoology and evolutionary biology, but may also appeal to a larger audience of general readers interested in mammalian evolution. The book begins with an introduction, describing the tools necessary to interpret the evolutionary history of South American mammals in geological terms and some of the early people who helped found South American mammalian paleontology. Chapter 2 describes the Mesozoic first mammals of Gondwana and what we are learning about them, dominant before the K/T extinction event. Then chapters 3 through 8 cover the Cenozoic, or "Age of Mammals", highlighting the major mammalian groups of South America that replaced the earlier mammals of Gondwana. These groups include the marsupials, native ungulates, the xenarthrans (armadillos, anteaters, sloths), the caviomorphs (rodents), and the platyrrhine monkeys. Chapters 9 and 10 address the Antarctic La Meseta fossils and the Colombian La Venta fossil faunal assemblages. Chapter 11 discusses the neotropical mammals that invaded the Caribbean Islands, and illustrates the influence South America has had on adjacent faunas. Chapter 12 describes the origin of the Amazon River and the role it has played in the evolution of the mammals and other flora and fauna. Chapter 13 tells the story of the Great American Biotic Interchange (GABI), and chapter 14 follows this up with a discussion of the Pleistocene mammal communities and their eventual extinction. Chapter 15 concludes the text by discussing the modern mammals of South America, and how despite the extensive Pleistocene extinctions there is still a lot of mammalian diversity in South America. .

Book Description
Emerging technologies are opening new avenues for the study of past and present ecosystems. Computer-aided visualization and analysis of fossil specimens through X-ray tomography has revolutionized the study of organisms. X-ray tomography, or X-ray computed tomography, is a characterization technique for generating 3D information from 2-dimensional X-ray image slices. X-ray imaging is based on the differential absorption or scattering of an X-ray source to reveal internal attributes of biological specimens. High-resolution tomography can retrieve compositional and structural information of small objects or the macrostructure of larger objects non-destructively, allowing fossils to be characterized in three dimensions and in unprecedented detail. This has enabled paleontologists to gain important insights into the anatomy, development, and preservation of specimens. The resulting digital 3D reconstructions can be used in functional analyses to test hypotheses regarding the paleobiology of extinct organisms that could transform our understanding of long-studied fossil groups, and the narratives of organismal and ecological evolution. Furthermore, this proliferation of digital datasets should make the widespread sharing and dissemination of 3D data possible, providing access to rare fossil material worldwide.

Book Description
An in-depth look at the origin and evolutionary radiation of the synapsids. About 320 million years ago a group of reptiles known as the synapsids emerged and forever changed Earth’s ecological landscapes. This book discusses the origin and radiation of the synapsids from their sail-backed pelycosaur ancestor to their diverse descendants, the therapsids or mammal-like reptiles, that eventually gave rise to mammals. It further showcases the remarkable evolutionary history of the synapsids in the Karoo Basin of South Africa and the environments that existed at the time. By highlighting studies of synapsid bone microstructure, it offers a unique perspective of how such studies are utilized to reconstruct various aspects of biology, such as growth dynamics, biomechanical function, and the attainment of sexual and skeletal maturity. A series of chapters outline the radiation and phylogenetic relationships of major synapsid lineages and provide direct insight into how bone histological analyses have led to an appreciation of these enigmatic animals as once-living creatures. The penultimate chapter examines the early radiation of mammals from their nonmammalian cynodont ancestors, and the book concludes by engaging the intriguing question of when and where endothermy evolved among the therapsids. “Ever since Nick Hotton’s book from the 1980s we have needed an update on the biology of therapsids, and it has been Anusuya Chinsamy-Turan and her students and associates who through their bone histological work have made the greatest progress in this field.” —Martin Sander, Steinmann Institute, University of Bonn “Forerunners of Mammals is full of meticulous detail . . . [I]t also contains a number of excellently rendered illustrations of some of the animals covered in the book, and the final chapter is a discussion of the evolution of endothermy that anyone with a background in biology might find of interest. . . . Recommended.” —Choice “Forerunners of Mammals will take interested readers beyond the classic jaw-to-ear appreciation of therapsids, towards a deeper appreciation of the ancestry of mammals.” —Journal of Mammalian Evolution “This volume represents a state-of-the-art contribution to our understanding of the paleobiology of how mammals arose, and what factors contributed to their evolutionary radiation and eventual success. It is highly recommended for anyone interested in these topics, and will be accessible to readers with minimal background in bone histology and synapsid paleontology.” —Quarterly Review of Biology

Book Description
The fossil record on Mesozoic mammals has expanded by orders of magnitude over the past quarter century. New specimens, some of them breathtakingly complete, have been found in nearly all parts of the globe at a rapid pace. Coupled with the application of new scientific approaches and techniques, these exciting discoveries have led to profound changes in our interpretation of early mammal history. Mesozoic mammals have come into their own as a rich source of information for evolutionary biology. Their record of episodic, successive radiations speaks to the pace and mode of evolution. Early mammals were small, but they provide key information on the morphological transformations that led to modern mammals, including our own lineage of Placentalia. Significant and fast-evolving elements of the terrestrial biota for much of the Mesozoic, early mammals have played an increasingly important role in studies of paleoecology, faunal turnover, and historical biogeography. The record of early mammals occupies center stage for testing molecular evolutionary hypotheses on the timing and sequence of mammalian radiations. Organized according to phylogeny, this book covers all aspects of the anatomy, paleobiology, and systematics of all early mammalian groups, in addition to the extant mammalian lineages extending back into the Mesozoic.
