Microfossils is the definitive guide to all the major microfossil groups. In recent years a greater understanding of species' concepts and stratigraphical ranges, advances in the completeness of the microfossil record and the advent of molecular techniques in classification have led to major changes in the classification and applications of microfossils. This new edition of Microfossils has been restructured and rewritten to take into account these significant advances to provide a complete guide to taxonomy, phylogeny, ecology and palaeoecology of microfossils and their applications. This new edition includes: major revisions incorporating the latest available research; a new section on isotopes, and on applications in stratigraphy, geothermometry and evolution; coverage of the major developments in the use of microfossils in palaeo-oceanography and palaeoclimatology; and photographs to support the line drawings. Microfossils is an essential reference tool and laboratory guide for undergraduate and graduate students of micropalaeontology.
