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

The Beginning of the Age of Dinosaurs

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

Palaeobiology of Giant Flightless Birds

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

Evolution and Development of Fishes

Fish, or lower vertebrates, occupy the basal nodes of the vertebrate phylogeny, and are therefore crucial in interpreting almost every feature of more advanced vertebrates, including amphibians, reptiles, birds and mammals. Recent research focuses on combining evolutionary observations - primarily from the fish fossil record - with developmental data from
