A note on the biostratigraphy of Paleocene-Eocene larger foraminifera from western Cuba

摘要

Larger foraminifera were collected from various Paleocene and Eocene localities in western Cuba. Included was a mea- sured section at San Francisco de Paula in Ciudad de la Habana Province in the Apolo and Capdevila Formations. This section spans the Paleocene/Eocene boundary and has been the focus of intensive biostratigraphic work. In this study, the stratigraphic occurrences of the Larger formainifera were correlated to biozoonations based on planktonic formainifera, calcareous nannofossils, radiolaria, and smaller benthic foraminifera already identified at San Francisco de Paula.
