Book Description
One of the most intriguing paleobiogeographical phenomena involving the origins and gradual sundering of Gondwana concerns the close similarities and, in most cases, inferred sister-group relationships of a number of terrestrial and freshwater vertebrate taxa, e.g., dinosaurs, flying birds, mammals, etc., recovered from uppermost Cretaceous/ Paleogene deposits of West Antarctica, South America, and NewZealand/Australia. For some twenty five extensive and productive investigations in the field of vertebrate paleontology has been carried out in latest Cretaceous and Paleogene deposits in the James Ross Basin, northeast of the Antarctic Peninsula (AP), West Antarctica, on the exposed sequences on James Ross, Vega, Seymour (=Marambio) and Snow Hill islands respectively. The available geological, geophysical and marine faunistic evidence indicates that the peninsular (AP) part of West Antarctica and the western part of the tip of South America (Magallanic Region, southern Chile) were positioned very close in the latest Cretaceous and early Paleogene favoring the “Overlapping” model of South America-Antarctic Peninsula paleogeographic reconstruction. Late Cretaceous deposits from Vega, James Ross, Seymour and Snow Hill islands have produced a discrete number of dinosaur taxa and a number of advanced birds together with four mosasaur and three plesiosaur taxa, and a few shark and teleostean taxa.

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
Tectonic plates are constantly moving, either crashing into one another creating a mosaic of mountains and shallow seas, or tearing apart and isolating large swathes of land. In both cases plate tectonics separates populations leading to the evolution of biota. Tectonics is also responsible for the destruction life, for instance when large coral reefs or shallow seas are compressed to form mountain peaks. Could recent research into these processes provide enough evidence to show that tectonics may be the ultimate driver of life on Earth? Our book delves into the current research in tectonics, particularly neotectonics, and its impact on rapid changes on biogeographical classification, also known as bioregionalisation. We also introduce a new term biotectonics that studies the impact of tectonics on biogeoregionalisation. The question we ask is how tectonics directly influences the distribution of biota in four case studies: the Mesozic and early Palaeogene Australides, which spans the Proto-Pacific coast of the South America, Antaractica and Australiasia; and the Neogene of Australia. To conclude we examine the role of neotectonics on tranistion zones and the Amazon Basin and make a case for biotectonic extinction.

Book Description
Where Did They Come From? The Origins of South American Fauna offers a fascinating journey into the origins of South American flora and fauna. Exploring life on the continent before and after the breakup of Gondwana, it delves into how creatures arrived in South America, be it through drifting across oceans or traversing land bridges. From birds and reptiles to mammals and fish, this book provides a comprehensive compendium of biological diversity, discussing their origins and evolutionary paths. Readers will gain insights into the mechanisms of animal dispersal, evolution, and the impact of the Great Biotic Interchange. The book also lists references for further exploration of the subject. The book is structured into five parts: Building South America: Covers tectonic movements, climate changes, and breaching isolation. Shaping South America: Explores the landforms and diverse biomes across the continent. Vertebrates within South America: Discusses unique amphibians, reptiles, fish, mammals, and birds that evolved on the continent. Vertebrates immigrating to South America: Examines exotic reptiles, birds, and mammals that found their way to the continent. The author also lists the families of almost all genera of South American animals, while giving knowledge of their origins. Recent Arrivals - the Great Biotic Interchange: Explores the significant interchange of various species that occurred later. Ideal for students, biologists, and anyone curious about the natural world, this book is a captivating read that uncovers the incredible history of South American fauna and its evolutionary tapestry.

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
Snakes comprise nearly 4,000 extant species found on all major continents except Antarctica. Morphologically and ecologically diverse, they include burrowing, arboreal, and marine forms, feeding on prey ranging from insects to large mammals. Snakes are strikingly different from their closest lizard relatives, and their origins and early diversification have long challenged and enthused evolutionary biologists. The origin and early evolution of snakes is a broad, interdisciplinary topic for which experts in palaeontology, ecology, physiology, embryology, phylogenetics, and molecular biology have made important contributions. The last 25 years has seen a surge of interest, resulting partly from new fossil material, but also from new techniques in molecular and systematic biology. This volume summarises and discusses the state of our knowledge, approaches, data, and ongoing debates. It provides reviews, syntheses, new data and perspectives on a wide range of topics relevant to students and researchers in evolutionary biology, neontology, and palaeontology.
