Major advances in our understanding of the history of life on Earth have resulted from the study of exceptionally well-preserved fossil sites (LagerstAtten). Study of such sites from around the world and from different periods in geological time can provide a fairly complete picture of the evolution of ecosystems down the ages.With this aim in mind, the authors have brought together succinct summaries of 14 of the better-known fossil Lagerstatten, beautifully illustrated throughout by over 250 colour photographs and diagrams.Following a general introduction to fossil LagerstAtten, each chapter deals with a single fossil site and follows the same format: its evolutionary position and significance; its background sedimentology, stratigraphy and palaoenvironment; a description of the biota and palaeoecology, and a comparison with other similar LagerstAtten. There are appendices of further reading, relevant museums and suggestions for visiting the sites.This book will be of value to a wide range of students and professionals in palaeontology and related sciences, and to amateur enthusiasts.
