Although their value as palaeoenvironmental and palaeoclimatic proxies is widely acknowledged, ostracods have traditionally been considered to be of only limited use in British Pleistocene biostrati-graphy. To some extent this is due to the patchy and fragmentary nature of most onshore Pleistocene deposits, precluding the establishment of long, continuous records on which to base species ranges. It is also a result of taxonomic continuity; the majority of British Pleistocene species are still alive today and relatively few extinct taxa, such as might provide stratigraphical markers, have been recognized. Examples of the latter were discussed by Griffiths (2001) in his...

Ostracods in British Stratigraphy
This book charts the stratigraphical distribution of ostracods in the Cambrian to Pleistocene deposits of Britain and outlines their utility for dating and correlating rock sequences, as well as indicating aspects of their palaeoenvironmental and palaeogeographical significance. These small bivalved crustaceans are the most abundant arthropods in the fossil record. Indeed, the stratigraphy of Britain, which embraces many type-sequences, provides a particularly rich and full record of them, from at least the basal Ordovician, and from the British Cambrian there is a biostratigraphy based on their ‘relatives’, the bradoriids and phosphatocopids. Ostracod distributions demonstrate the ecological success story of the group, occupying as they do marine, non-marine and even ‘terrestrial’ habitats. Written by current specialists in the field, this book is an authoritative account and will be welcomed by all micropalaeontologists and applied geologists in the industrial and academic world alike. It is richly illustrated with over 80 plates of electron micrographs and specially drawn maps, diagrams and range-charts.
