Evolution of Dental Tissues and Paleobiology in Selachians

Chondrichthyans possess unique anatomical features compared to other vertebrates, in particular a fully cartilaginous skeleton and a permanently renewed dentition. These characteristics make the fossilization of whole bodies difficult and consequently their fossil record consists mainly of a large number of isolated teeth. The study of their dentition is therefore of primary interest for our understanding of the evolution of this group. Beyond the dental morphology, the structure of the tissues composing the dentition has proved an important source of information, sometimes difficult to interpret, on the eating habits and the paleobiology of these animals. This book makes a thorough review of the existing theories in this field of research as well as introducing new elements from more recent studies. Through close reference to the fossil record of ancient selachians it examines what the study of dental tissue in cartilaginous fish can tell us about the evolution and the past biology of these animals, as well as what we can learn about the evolution of teeth themselves. Focuses on the evolution of the teeth microstructure of the cartilaginous fishes Offers a complete overview of the terminology used to describe fish tooth microstructures Offers an overview of convergent enameloid microstructures between actinopterygians (ray-finned fishes) and chondrichthyans to enable better understanding of the evolution of this kind of tissue Highlights the importance of isolated fossil teeth to understand the evolution of whole clades Discusses the use of isolated fossil teeth to understand the evolution of whole clades

Vertebrate Skeletal Histology and Paleohistology summarizes decades of research into the biology and biological meaning of hard tissues, in both living and extinct vertebrates. In addition to outlining anatomical diversity, it provides fundamental phylogenetic and evolutionary contexts for interpretation. An international team of leading authorities review the impact of ontogeny, mechanics, and environment in relation to bone and dental tissues. Synthesizing current advances in the biological problems of growth, metabolism, evolution, ecology, and behavior, this comprehensive and authoritative volume is

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

The fossil record of giant flightless birds extends back to the Late Cretaceous, more than 70 million years ago, but our understanding of these extinct birds is still incomplete. This is partly because the number of specimens available is sometimes limited, but also because widely different approaches have been used to study them, with sometimes contradictory results. This book summarizes the current knowledge of the paleobiology of seven groups of giant flightless birds: Dinornithiformes, Aepyornithiformes, Dromornithidae, Phorusrhacidae, Brontornithidae, Gastornithidae and Gargantuavis.

Evolutionary Biology, of which this is the twenty-second volume, continues to offer its readers a wide range of original articles, reviews, and commentaries on evolution, in the broadest sense of that term. The topics of the reviews range from anthropology, molecular evolution, and paleobiology to principles of systematics. In recent volumes, a broad spectrum of articles have appeared on such subjects as asymmetric sexual isolation, biochemical systematics in plants, species selection, DNA hybridization and phylogenetics, modes of evolution in Pleistocene

Diverse and abundant Middle and Late Triassic elasmobranch ichthyoliths (microscopic shark teeth and scales) coexisting with conodonts, ammonoids, and bivalves recovered from carbonates in the Peace River area of British Columbia provide an excellent biostratigraphic framework for Triassic strata. This report provides systematic descriptions and illustrations of Triassic elasmobranch ichthyoliths including seven species of teeth and 19 new form genera and 53 new form species of scales. A provisional ichthyolith zonation for the Middle and Upper Triassic is proposed for the Peace

The case history approach has an impressive record of success in a variety of disciplines. Collections of case histories, casebooks, are now widely used in all sorts of specialties other than in their familiar appli cation to law and medicine. The case method had its formal beginning at Harvard in 1871 when Christopher Lagdell developed it as a means of teaching. It was so successful in teaching law that it was soon adopted in medical education, and the collection of cases
