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 of chirothere 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 features a 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.

This volume addresses major evolutionary changes that took place during the Mesozoic and the Cenozoic. These include discussions on major evolutionary radiations and ecological innovations on land and at sea, such as the Mesozoic marine revolution, the Mesozoic radiation of vertebrates, the Mesozoic lacustrine revolution, the Cenozoic radiation of mammals, the evolution of paleosol biotas, and the evolution of hominins. The roles of mass extinctions at the end of the Triassic and at the end of the Cretaceous are assessed. This volume set provides innovative reviews of the major evolutionary events in the history of life from an ichnologic perspective. Because the long temporal range of trace fossils has been commonly emphasized, biogenic structures have been traditionally overlooked in macroevolution. However, comparisons of ichnofaunas through geologic time do reveal the changing ecology of organism-substrate interactions. The use of trace fossils in evolutionary paleoecology represents a new trend that is opening a window for our understanding of major evolutionary radiations and mass extinctions. Trace fossils provide crucial evidence for the recognition of spatial and temporal patterns and processes associated with paleoecologic breakthroughs.

Around 210 million years ago, life on Earth experienced sweeping changes. Many archaic reptiles and mammalian predecessors became extinct and were replaced by dinosaurs, pterosaurs, crocodiles, turtles, mammals, and essentially all of the major modern vertebrate groups except the birds. This period of change, which took place over a period of approximately five to ten million years, ushered in the beginning of the 'Age of Dinosaurs,' a period that lasted 160 million years to the end of the Cretaceous 65 million years ago. In the past decade, paleontologists have come to know a great deal more about this crucial interval of time. New discoveries, ideas, and insights from scientists in many related- disciplines have created new paradigms about the beginning of the 'Age of Dinosaurs.' What were the animals that preceded the dinosaurs like? How did the dinosaurs originate, and what do we know of their early history? Was their ascent tied to evolutionary innovations, global climatic and ecological changes, or just chance factors? How do paleontologists decide about the evidence preserved in the fossil record, and what areas now require major thought and reevaluation? In this book, 31 specialists in the paleontology of this era consider these and other questions related to Late Triassic and Early Jurassic times - the beginning of the 'Age of Dinosaurs,' its fauna, flora, climate, stratigraphic relationships, and major evolutionary changes. The book is divided into sections on background, Late Triassic taxa and faunas, changes across the boundary, Early Jurassic taxa and faunas, and major macroevolutionary patterns. This comprehensive volume is richly illustrated and is intended for students and professionals in the areas of paleontology, evolutionary biology, geology, and vertebrate zoology. Introductory and summary chapters are provided to acquaint the non-specialist with the issues and the setting of this interval of time in which the ancestral components of the modem fauna, as well as the Dinosauria, first appeared to rule the Earth.
