The dicynodonts, an important group of permo-triassic reptiles, were the first really successful herbivorous tetrapods. Moreover they provided the bulk of the prey species for the ecosystem in which the mammals evolved, which makes them interesting in a wider context. The dicynodonts left an abundant fossil record, mainly in what is now southern and eastern Africa. This abundance enables investigation of their community structure and permits observations to be made on the changes in diversity that the group underwent throughout history. Such palaeoecological studies are becoming increasingly important since they have direct bearing on the evolution of other fossil groups. Their detailed preservation allows functional considerations to be derived from structure, providing evidence for discussion of reproduction, thermoregulation and social behaviour - all important aspects of the study of the evolution of mammals. These studies are summarized by a recognized expert in the field and should be valuable to those interested in evolution, palaeoecology and palaeobiology, as well as geologists and zoologists. This book should be of interest to evolutionary biologists, palaeoecologists, palaeobiologists, geologists and zoologists.

This book looks at how an animal is organized to carry out a difficult task - that of feeding on plants. The complex adaptations necessary to enable animals to obtain nutrients successfully from a herbivorous diet are many. What structures are needed in the mouth, for example, or in the digestive system? How is behaviour adapted to allow an animal to survive and reproduce on a diet of plant material? For the first time, these problems are examined here purely from the perspective of the reptiles. Individual groups are looked at the structural, physiological and ecological adaptations of the herbivorous members are reviewed. The groups discussed include the modern reptiles, the lizards and the turtles and also extinct reptiles, the dinosaurs and the mammal-like reptiles. Common themes are teased out and arranged chronologically to help gain an understanding of the patterns of diversity change in the group. This book will be of great interest to researchers and students of zoology, palaeontology, evolution, ecology, functional anatomy and morphology.
