The Australopithecine Face provides an introduction to the interpretation of the facial skeleton of Australopithecus, a part of the anatomy well represented in the African collections. This book presents important morphological differences between the early hominid taxa and interprets them in a biochemical, functional, evolutionary framework. Organized into seven chapters, this book begins with an overview of the description of the face of the four species of Australopithecus, extending to comparisons both within the genus and with other primates. This text then provides an analysis of the facial morphology of Australopithecus in terms of structural significance. Other chapters consider the taxonomic and phylogenetic status of the australopithecine species in light of the description and comparison. This book discusses as well the changes in the morphology and topography of the facial mask. The final chapter deals with the phylogenetic assignment of the different species. This book is a valuable resource for anthropologists.
