Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: This beautifully illustrated exploration of the diversity, anatomy, and evolution of dinosaur feeding adaptations is the first and only in-depth look at this crucial aspect of paleoecology. In An Illustrated Guide to Dinosaur Feeding Biology, experts Ali Nabavizadeh and David B. Weishampel bring dinosaurs to life on the page by exploring and illustrating their feeding adaptations. Whether dinosaurs were carnivorous, herbivorous, or omnivorous, their evolution produced a multitude of specialized adaptations that helped shape their ecologies. Dinosaur skulls show a variety of bone and joint specializations ideal for withstanding stresses and strains induced by high bite forces with strong jaw musculature. The bladed, steak-knife dentition of many carnivorous dinosaurs was well-suited for slicing meat and crushing bones, while the leaf-shaped, sometimes tightly packed dentition of many herbivorous dinosaurs was ideal for grinding up a variety of plant material. The first book of its kind, An Illustrated Guide to Dinosaur Feeding Biology is a synthesis of over a century of dinosaur feeding biology research, from the earliest hypotheses in the 1800s to today's studies using advanced techniques. Intended for both researchers and dinosaur enthusiasts alike, this book discusses functional morphological studies highlighting comparative anatomy, tooth wear, muscle reconstruction, and biomechanical analysis using modeling techniques like finite element analysis and multibody dynamics analysis. In addition to the feeding apparatus, Nabavizadeh and Weishampel explore postcranial adaptations and discuss the evolution of dinosaurs and their paleoecology more broadly. Integrating these various factors improves our understanding of dinosaurs as the living beings they were in their ecosystems millions of years ago and ultimately expands our knowledge and perspective of today's ecosystems by framing them in a broader evolutionary context.

Download or read book In the Shadow of the Dinosaurs written by Nicholas C. Fraser and published by Cambridge University Press. This book was released on 1997-08-28 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: The early Mesozoic period was a critical period in the evolution of life on land when most of todays major groups of terrestrial vertebrates arose and dinosaurs and pterosaurs rose to prominence. In recent years this period has received a great deal of attention from palaeontologists, and it is now felt that the small vertebrates which lived in the shadows of the first dinosaurs tell us a great deal about the evolution of modern terrestrial ecosystems. This book is an attempt to collate all the information on the small vertebrates and features contributions by experts with international reputations in their fields. There are chapters on the taxonomy and phylogeny of the key vertebrate groups followed by a section dealing with the most significant fossiliferous assemblages worldwide. The final section looks at how faunal turnover at this time is measured and examines the possibility of mass extinctions.
Download or read book Evolution of Jaw Mechanisms in Ornithopod Dinosaurs written by David B. Weishampel and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Ornithopoda, one of five suborders within the Ornithischia, was originally proposed by Marsh in 1881 to include those bipedal dinosaurs possessing a predentary bone fitted over the rostral end of the mandibles. Ornithopods as recognized today can be further characterized by moderately long facial skele tons equipped with well-developed, often toothless premaxillae and moderate to large external nares. Maxillary and dentary dentitions vary but usually consist of at least one replacement series beneath the functional set; some have many rows of successional teeth. Tooth morphology suggests ornithopods were suc cessful herbivores but, as will be discussed, the precise way(s) in which ornitho pods chewed their food, hence lending important information about their tro phic position, has not been settled. Postcranially, ornithopods show specializa tion for bipedality in hindlimb construction and lack well-developed protective structures on their flanks, back, and tail. The Ornithopoda can itself be divided into five families: Fabrosauridae, He terodontosauridae, Hypsilophodontidae, 19uanodontidae, and Hadrosauridae (subdivided into the subfamilies Hadrosaurinae and Lambeosaurinae). Both fabrosaurids and heterodontosaurids, first known from the Late Triassic and Early Jurassic of Argentina and South Africa, were small animals differing in details of cranial, dental, and appendicular anatomy. Fabrosaurids are be lieved to represent the basal ornithopod stock (Galton 1972, 1978; Thulborn 1970a, 1972). During the Jurassic, ornithopods underwent major radiations that included the medium- to large-sized Hypsilophodontidae and the large bodied Iguanodontidae, both of which survived into the Cretaceous.

Available in PDF, EPUB and Kindle. Book excerpt: A new edition of the illustrated compendium that is “a gift to serious dinosaur enthusiasts” (Science). What do we know about dinosaurs, and how do we know it? How did they grow, move, eat, and reproduce? Were they warm-blooded or cold-blooded? How intelligent were they? How are the various groups of dinosaurs related to each other, and to other kinds of living and extinct vertebrates? What can the study of dinosaurs tell us about the process of evolution? And why did typical dinosaurs become extinct? These questions and more are addressed in this new, expanded edition of The Complete Dinosaur. Written by leading experts on the “fearfully great” reptiles, the book covers what we have learned about dinosaurs, from the earliest discoveries to the most recent controversies. Where scientific contention exists, the editors have let the experts agree to disagree. The Complete Dinosaur is a feast for serious dinosaur lovers, from the enthusiastic amateur to the professional paleontologist.

Download or read book Anatomy Phylogeny and Palaeobiology of Early Archosaurs and Their Kin written by Sterling J. Nesbitt and published by Geological Society of London. This book was released on 2013 with total page 605 pages. Available in PDF, EPUB and Kindle. Book excerpt: Archosaurs, an important reptile group that includes today's crocodiles and birds, arose during the Triassic in the aftermath of the greatest mass extinction of all time. In the last 20 years, our understanding of the early evolution of the group has improved substantially with the discovery of new fossils and species of early archosaurs and their closest relatives, a better understanding of the relationships of these animals, and new insights into their palaeobiology. In order to synthesize these new data, researchers of early archosaurs from around the world met at the first symposium of early archosaur evolution at the IV Congreso Latinoamericano de Paleontología de Vertebrados (September 2011) in San Juan, Argentina. This symposium facilitated collaboration and strove to paint a better understanding of these extraordinary animals. The resultant body of work is a state-of-the-art examination of early archosaur groups and their close relatives including historical, anatomical, biogeographical, evolutionary and palaeobiological data. This contribution furthers our knowledge of the anatomy, relationships, and palaeobiology of species-level taxa as well as more global patterns of archosaur evolution during the Triassic -- P. 4 of cover.
