Invertebrate palaeontology and evolution / Палеонтология и эволюция беспозвоночных

The first three editions of this textbook were published in 1979, 1986 and 1992, and I trust that tins new one, necessitated by so many advances both in fact and theory', will retain its function as a course text for students of palaeontology from their second year onwards. 1 have made substantial changes to Chapters 1-3,7, 8 and 12, and the Trace Fossils section has been transferred from Chapter I to die last chapter. AH the other chapters have been revised to a greater or lesser extent. 1 have redrawn about half of the illustrations: a singularly congenial occupation for long winter evenings, and l hope that these will prove of value in helping students to understand the anatomy and terminology of fossil invertebrates.
Key words appear in bold at their first mention in the text. There is no specific index tor them, but they appear in the General Index.
As before, 1 wish to thank all my friends, colleagues and family who have given me such assistance iu preparing this new edition. Derek Briggs, Colin Scmtton and Rachel Wood gave excellent advice at the beginning of the project as to how I should proceed with the fourth edition, and I have taken on board most of their suggestions. As always, these colleagues, together with David Harper, Peter Sheldon, Susan Rigby, Liz Harper, Dick Jefferies, John Cope, Alan Owen and various others have helped me at all stages, and so have many others, too numerous to mention, in my own country and abroad, and my thanks arc due to all. <...>
