This book serves as an introduction to the Cretaceous geology and palaeontology of south-central Africa, covering the whole of Southern and Eastern Africa and Angola. Fifty two plates illustrate almost 1000 species and provide a field guide to the macrofossils of the subcontinent. The book will be of value to field geologists, students and non-specialists with an interest in the natural world. A bibliography of the Cretaceous palaeontology and stratigraphy of the subcontinent is provided. Features: Provides a concise account of the Cretaceous geology for 13 African regions Includes beautiful illustrations and a comprehensive bibliography Fossils are presented in stratigraphical order, allowing easy determination of the age deposits.

This open access multi-authored book presents a 'state of the science' synthesis of knowledge on the biodiversity of Angola, based on sources in peer-reviewed journals, in books and where appropriate, unpublished official reports. The book identifies Angola as one of the most biologically diverse countries in Africa, but notes that its fauna, flora, habitats and the processes that drive the dynamics of its ecosystems are still very poorly researched and documented. This 'state of the science' synthesis is for the use of all students of Angola's biodiversity, and for those responsible for the planning, development and sustainable management of the country's living resources. The volume brings together the results of expeditions and research undertaken in Angola since the late eighteenth century, with emphasis on work conducted in the four decades since Angola's independence in 1975. The individual chapters have been written by leaders in their fields, and reviewed by peers familiar with the region.

Everyone working in a problem as complex as continental drift, must at some time have feit the need for an objective data summary in fields other than his own. It is a scientific dilemma that, aIthough there is evident need for researchers with competence in many fields (the classical natural scientist), the time in volved in acquiring such broad experience is so great as to ren der the task largely impossible. The alternative seems to be the team approach, and we have espoused it in tbis volume. Editors and contributors alike have tried in this book to keep the accent upon factual information and to reduce interpretation to a minimum. Interpretation there must be, however, since without it science is but an inteHectual pastime comparable to pbilately. The librarian's need to classify results in the appearance of our names upon the spine oftbis volume, however, we would like to make it clear that the book has been a truly cooperative effort and could not have succeeded but for the active help of the individual contributors, whose assistance seldom was re stricted to their chapters. Special thanks must be given to our South American coHeagues, for the tolerance with which they viewed out editorial attempts, and to Dr. E. Machens, for his careful review of the translation of his manu script. We wish also to acknowledge the help of Dr. C. W.
