Benthic foraminifera from the classic southern Caribbean region are presented in this book, to provide valuable information on ranges for biostratigraphers working in the region and beyond. Around 1000 of the more important species are assembled - from the Barremian (early Cretaceous) to the middle Miocene, approximately 120 to 10 million years before the present. The deeper water benthic species are tied in to the zonal scheme used in Plankton Stratigraphy, published by Cambridge University Press in 1985. The taxa have been brought up to date generically, and in many cases new comparisons between species have been made - the late Cretaceous and early Paleogene are particularly detailed. This information, together with detailed illustrations, will enable the taxa to be used stratigraphically.

This comprehensive synthesis of our knowledge of the biostratigraphy of marine plankton is the work of an international team of eighteen authors. It covers all the major fossil groups that can be used to date sediments and rocks in the time interval Late Mesozoic to Holocene. Altogether more than 3200 taxa are considered, almost all of which are illustrated and depicted on range charts, making the book a valuable work of reference in the earth sciences. For ease of reference by specialists interested in either calcareous or non-calcareous microfossils, the original work is now divided into two independent volumes. Volume I covers the calcareous microfossils and includes planktic foraminifers, calcareous nannofossils and calpionellids.
