This is the first time that a single book has attempted to cover the whole of the fossil history of insects so comprehensively. The volume embraces the history of insect palaeontology, methods for studying fossils, the taphonomic processes leading to their formation, the diagnostic features of all insect orders, both extant and extinct, the major fossils of each order, and the implications that can be drawn from the palaeoentomological record about past ecology and climates. Many new insights are presented. It is the product principally of the largest palaeoentomological group in the world, in Moscow, and makes full use of the remarkable collection that these workers have developed. It includes a very large number of illustrations showing both real fossils and reconstructions of extinct taxa. The systematic part is treated in a phylogenetic framework, with information on fossil groups being used to help interpret relationships. There is an appendix that provides information on virtually all sites where fossil insects have been found. This book is essential to all students of palaeoentomology and contains a wealth of information that will be of interest to students of insect evolutionary relationships and of palaeontology in general.
