Some imperforate larger foraminifera from the Paleogene of Jamaica and the Nicaragua Rise
Journal of Foraminiferal Research
Date of Publication
Two major types of larger foraminiferal assemblages can be recognised in the Paleogene rocks of the Caribbean region. Assemblage I species, mainly orbitoids and nummulitids, are widespread through the Caribbean and often are found in turbidites in arc/subduction zone sedimentary sequences. Assemblage II species, mostly imperforate, are more local in their distribution, many being found only in platform carbonates and restricted paleogeographically almost completely to the northern Caribbean. One of the more extensive carbonate buildups of the Caribbean Paleogene cover the present area of Jamaica and the northern part of the Nicaragua Rise. As part of a continuing review of larger foraminifera from that area, a number of informally recognised, undescribed or poorly known Assemblage II species are described in this paper. ....
