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.
