Project Details


The aim of the project is to build in the Caribbean area an Upper Cretaceous larger foraminifera biozonation (KSBZ) covering the whole ecological gradient from the shore to the lower limit of the photic zone, and allowing the biostratigraphic correlation of shallow water sediments across the Atlantic ocean by means of benthic organisms. The improvement of Transatlantic biostratigraphic correlation of shallow water facies is a prerequisite to understand the evolution of sedimentary basins, the reconstruction of paleoceanographic and/or paleoclimatic global events and the genesis of faunal provinces during the Upper Cretaceous. Abundance, diversity, and high evolutionary rates make larger foraminifera extraordinary useful fossil-index for Upper Cretaceous biozonation. Moreover, larger foraminifera are the only larger group of fossils having sufficiently diagnostic structures by which they can be identified to a taxonomic level of biostratigraphic significance in thin section.
