The transition from the Paleocene to the Eocene Epoch-approximately 55 million years ago-represents a critical moment in the earth's history, when the warmest climatic episode of the Cenozoic era occurred. This sudden global warming resulted in major turnovers among marine and terrestrial organisms. Although this episode has become one of the most popular areas of research in the geologic sciences in the past decade, there has not yet been a work that brings together the profusion of new results in one volume. This book offers by far the most comprehensive source of data on a critically important interval of the earth's history. The editors have brought together the finest scholars working today on the Paleocene-Eocene transition. Covering mammals, reptiles, invertebrates, and plants, as well as the spectrum of marine biotas, the book documents both the well-established and the lesser-known turnovers, such as those of the calcareous nannoplankton and terrestrial mollusks. The volume is also notable for its integration of knowledge culled from a wide variety of disciplines, geographic settings, fossil groups, and paleoenvironments.With 21 contributions and more than 180 illustrations, this book will be of great value as a reference source for a wide spectrum of scientists, from marine geologists and oceanographers to paleontologists, paleoclimatologists, and stratigraphers.

Geared towards a broad variety of students, Dinosaurs: The Textbook, sixth edition, is a concise and lucid presentation of the biological and geological concepts of dinosaur science. It clarifies the evolution, phylogeny, and classification of the various species while modeling the best approach for navigating new and existing research. Revised to reflect recent fossil discoveries and the current consensus on dinosaur science, this text moves through the major taxonomic groups-including theropods, sauropodomorphs, ornithopods, ceratopsians, pachycephalosaurs, stegosaurs, and ankylosaurs-and concludes with updated chapters on the behavior and extinction of the dinosaurs, their biological relationship to birds, and their representation (or misrepresentation) in art, literature, film, and other forms of popular culture. The sixth edition represents a major revision of the leading text for an introductory course on dinosaurs, including comprehensive updates based on the latest scientific discoveries, research, and literature.With an extensive art program revised by leading paleoartists that features cutting-edge illustrations, it is a complete reader-friendly pedagogical package with extensive end-of-chapter summary tools, review questions, a detailed glossary, a dinosaur dictionary, and a comprehensive index.

Geared toward a broad variety of students, Dinosaurs: The Textbook offers a concise and lucid presentation of the core biological and geological concepts of dinosaur science. Revised throughout to reflect recent fossil discoveries and the current scientific consensus, this seventh edition details the evolution, phylogeny, and classification of various dinosaur species while modeling the best approach for navigating new and existing research.Spencer G. Lucas takes readers through the major taxonomic groups, including theropods, sauropodomorphs, ornithopods, ceratopsians, pachycephalosaurs, stegosaurs, and ankylosaurs. He also examines the behavior and extinction of the dinosaurs, their biological relationship to birds, and their representation (or misrepresentation) in art, literature, film, and other forms of popular culture.This seventh edition of the leading text for introductory courses on dinosaurs incorporates comprehensive updates based on the latest research. Lucas highlights how dinosaur science is rapidly evolving, exploring how new discoveries, methods, and ideas are expanding the frontiers of knowledge. The book features cutting-edge and scientifically rigorous illustrations by leading paleoartists. It also includes extensive and reader-friendly end-of-chapter summary tools, review questions, a detailed glossary, a dinosaur dictionary, and a comprehensive index.

This book describes the microbiota of the intertrappean beds in the Chhindwara District, Madhya Pradesh, India. In this work, special emphasis is placed on the microbiota from the Late Cretaceous-Early Palaeocene transition of the central Narmada River region. Recently, the intertrappean beds of the Eastern Deccan Volcanic Province (one of the subprovinces of the Deccan Volcanic Province) have received considerable attention, which resulted in the addition of some significant biotic assemblages to the existing record from the Dindori-Chhindwara area of the province. The biotic assemblages include charophytes, ostracods, foraminiferans, fishes, frogs, lizards, turtles, crocodiles, and mammals. In spite of the recent discoveries, the known fossil record of the Late Cretaceous-Early Palaeocene biota of India is not sufficient and thus does not permit us to speculate on the possible impact of environmental changes triggered by the Deccan volcanic lava flows on the contemporary biota and toprecisely document their palaeoecologic, palaeoenvironmental and palaeobiogeographic implications. The recent biotic reports from the intertrappean beds exposed in the Chhindwara region of the Eastern Deccan Volcanic Province clearly indicate that these beds have a vast potential in terms of fossil content, which could reveal new and dissimilar biotic remains when compared to the Western Deccan Volcanic Province. The record of diverse accumulations of freshwater charophytes, brackish to freshwater ostracods, and planktic foraminiferal and fish assemblages from the intertrappean beds of Jhilmili and adjacent areas of Early Danian (P1a) age and lying just north of Chhindwara town and in the heart of peninsular India has intriguing implications for defining the age limits of the basaltic flows. The occurrence of non-marine taxa, for example, algae, molluscs, and vertebrates, associated with brackish water ostracods in the nearby Singpur and Mohgaon Kalan localities of the Chhindwara region, has also raised concerns about the sedimentary environments of these intertrappean beds. The new finds (presented in this book) prove useful for the better understanding of the palaeoecology and palaeoenvironment of the biota and also throw light on various paleobiogeographic models proposed for the northward drifting Indian plate. The microbiotic assemblages of the intertrappean beds of the eastern Deccan volcanic province at District Chhindwara, Madhya Pradesh are documented in this book. The microbiota of the central Narmada River region, the charophytes, ostracods, planktic foraminifera, and fishes, receive special attention in this study.
